    318ti (1996),my car have only,central locking, im trying to install a keyless entry.but i cant find the exact location of the wire to connect my keyless entry unit.

  • kazzam88 Jul 18, 2009

    which harness should i connect my keyless entry unit

  • kazzam88 Jul 18, 2009

    there is no alarm, it has only central locking,i did try to top some wire of my remote to the driver side "actuator".but nothing happen.

  • kazzam88 Jul 18, 2009

    im trying to in keyless entry(remote) with my 318ti bmw,please guide me for the correct connection or tapping.

  • kazzam88 Jul 18, 2009

    sorry i did not time any from that web,,anymore suggestion-

  • kazzam88 Jul 18, 2009

    yes please,im really run out of ideas,

  • kazzam88 Jul 18, 2009

    this vehicle came with no keyless entry as default , there is be no ready wiring harness.
    i did open the door panel,driver side and check the wiring, and test the wires:
    1st test: i supply every wire with positive line,result nothing happen.
    2nd test: i supply all wires with negative supply.nothing happen-

  • kazzam88 Jul 20, 2009

    is this a BMW factory kit you are installing? if not you are going to need a factory wiring diagram, but short of that locate the power lock relay, that is where you need to tap in for an aftermarket system. if this is a aftermarket system please give name and maker of system



    no its not a bmw kit product. yes i have a diagram of the remote kit.the wires are labeled,so i know which is for lock,unlock,parking light,power,ground,etc...the problem is, i cant find where to tapin this wire from the kit to my car (bmw 318ti model 1996).how to trigger the lock and unlock.

    what do you mean marker,is it the brand of the keyless entry?if that so,im sorry there is no mark in the module.but i can send you the image.

  • kazzam88 Jul 20, 2009

    back of the glove box

  • kazzam88 Jul 21, 2009

    how would i test this wires, to make it sure that i get the correct wire.

    thanks

  • kazzam88 Jul 30, 2009

    where or what wire should i tap the common line of the module?

  • kazzam88 Aug 02, 2009

    "you are in the right area from your pictures of glove box veiw
    the left hand connector X13252 is the outputs to door lock motors, pin 1(lock), pin 9(unlock), pin 2 is earth back from door lock motors"


    did i get it right the pin 2 earth is the common line.

    color codes of my module:

    black= ground

    red= +power

    green= unlock

    blue=lock

    yellow/black=common line

    violet=parking light.

  • kazzam88 Aug 03, 2009


    i hook up the wires as it show. why still not operating. i measure the voltage of my module(unlock & lock) is more than 12v.

  • kazzam88 Aug 03, 2009

    can i try the connector X13253, even my module is high voltage?if so, how would be the connection?

  • kazzam88 Aug 03, 2009

    connector X13253 (middle connector) is input from master switch (pin 1 on switch colour RT/GN/GE pin 19 on BCM) eg power = lock request, no power = unlock request
    i have 5 wires from my module to hook up(power +,power-,common line,unlock,lock)

    which pin from this connector should i tap in.

  • kazzam88 Aug 03, 2009

    blue/grey(BL/GR)
    pin 1 lock is (SW) BLACK
    pin 9 unlock is (WS)white



    which pin is blue/gray, is it the same with blue/white?

    because i dont see blue/grey.



    is there other way or trial to test.

  • kazzam88 Aug 04, 2009

    i tried changing the 3 wires,and also cut them,but still nothing happen.

    maybe i will try to connect with the othe connector x13253.

    can you show me how will be the connection.

    can you say it by colour,because its very hard wire is in a pin.

  • kazzam88 Aug 07, 2009

    what do you mean by beamer?

  • kazzam88 Aug 08, 2009

    my car have no alarm, only a central locking,when i lock my car either of the 2 doors and the trunk,all will be lock.So im looking for the right wire to hook my keyless entry module(aftermarket, no product name).i did a trial and error under the glovebox, drivers door panel, by using a test light probe. 1st by connecting the end of the test light probe in negative(ground) and the other end by tapping in each wire.( all doors are closed) the result, the light goes on with some wire,theres is no light in other wires. and i did the same procedure by connecting in positive(+).same result. why the actuator did not trigger(lock or unlock).

  • kazzam88 Aug 12, 2009

    im installing a aftermarket keyless entry,but the my problem is, i can find the right wire to tap or hook my module.

The only way to do this is with a service manual for that specific car. The lock system is controlled from an electronic control module that receives a radio frequency signal from your remote.Without a schematic and color code for the wires, it would be very difficult even for a technician.
The service manual will have the information and schematic for that module. It will cost you around 20.00 dollars.

The keyless entry/alarm system was standard only on the Active Pkg 318ti in that year. Even that one was port-of-entry installed. You can get the same kit from a dealer and install it yourself with the instructions that come with it. As the sticker implies: your car is pre-wired for easy installation. Not too difficult though I've never done it on a ti. Most likely access to the installation/wiring is easier on the ti than an "normal" E36 that requires glovebox removal. If it were me, I'd be doing the factory kit, depending on the deal you get on the kit.

Each remote transmitter had a unique ID code and the car can store up to 4 ID codes.

Preperation
1. Close all doors,trunk,and hood.
2. The security system must be in disarm mode and key must be removed from the ignition key slot.

Enter Code learning mode
3.Open trunk and leave it opened.
4. open the driver's door and sit in the driver's seat
5. Close the driver's door.
6. Cycle ignition switch 5 times between Off and On (DO NOT START ENGINE)
The red status light will illuminate continuously, and the siren will chirp once to indicate that the code learning mode has been initiated.
The ignition switch cycling must be performed within 10 seconds.
The sequence in steps 1-6 must be performed within 45 seconds.

Register/Delete ID Code(s)
7. Open driver's door (remain seated in driver's seat)
8. Close driver's door
9. Press and relase any button on the remote you wish to register into the system. The status led will shut off momentarily to indicate that one id code has been registered.
10. Repeat steps 7 to 9 to register the remain the ID codes.

Exiting code learning mode
11. Open driver's door and exit vehicle, leaving the door open.
12. Close trunk.
13. Close dirver's door. The LED will turn off and the siren will chirp once twice.
14. The initializaiton procedure is now completed; test all remotes to confirm operation.
----------- I installed the bmwalarm.com keyless entry system this morning. There were a couple of hitches but I was ultimately successful.

There are two things that I would warn others about if they decide to go this route:

1. Although it is called "plug-and-play", it really isn't. I expected to unplug my BMW keyless entry box (which came with the car but was not working) and plug this one in. That was not the case. You need to unplug the OEM wiring harnass that plugs into the "alarm port" located under the glove box. The harnass that comes with the bmwalarm.com system does not have a plug that goes into the alarm port. Instead there are 8 wires, each with a connector that plug into the alarm port individually (red wire to pin 1, yellow wire to pin 2, etc.). I decided to cannibalize the connector from the OEM harnass and hook it up to the new harnass to make this a cleaner and more reliable setup. One tip for others: the alarm port is difficult to reach, but it can be unmounted for easier access by sliding the entire connector forward after releasing a plastic catch. Shine a flashlight in there and it will be obvious.

2. My other, and more major, complaint is the installation and programming instructions. Although written in English, they are nearly incomprehensible. On the installation, several pages are spent on the mechanics of removing the glovebox, knee bolster, etc. but the electrical connectivity is not very well detailed and complicated by the fact that the instructions are covering two different models which connect differently. There is no troubleshooting guide. Once installed you have to program the keyless remotes and set the various features of the system. As an example, to enter programming mode you turn on the ignition and press the "valet switch" 3 or 6 times depending on whether you want "designated mode" or "auto mode". It turns out that "designated mode" means single button lock/unlock and "auto mode" means one button locks and the other unlocks. There are six features that can be enabled/disabled but I couldn't figure most of them out and ended up doing a trial and error discovery process. This was all made more difficult by the fact that the manual says you will hear confirmation "chirps" as you program the unit but I never heard any chirps and had to rely on the LED and carefully following the instructions.

Bottom line: I now have a keyless entry system. The fobs are about the same size as the orginal BMW fobs and the system works fine. The installation was a bit of an adventure. I would recommend this system only to the fairly brave Do-It-Yourselfer.
check out and reply.will be always waiting to help you.when ever you require more help.please keep updated.please do rate the solution if helped.thank you for using fixya.

You are in the right area from your pictures of glove box veiw
the left hand connector X13252 is the outputs to door lock motors, pin 1(lock), pin 9(unlock), pin 2 is earth back from door lock motors.

connector X13253 (middle connector) is input from master switch (pin 1 on switch colour RT/GN/GE pin 19 on BCM) eg power = lock request, no power = unlock request

    can use test light back probe connectors on BCM to confirm polarity for lock and unlock events from information i supplied previously.

    depending on your system you are trying to fit it may want to be fitted to request side of BCM. so that the aftermarket system out puts request signal to BCM then BCM will operate door lock motors, if aftermarket system has only 1 out put wire.

    if it has a separate lock and unlock out put on aftermarket module hook up to out put connector on BCM left side connector.

  • Steve Hurc
    Steve Hurc Jul 30, 2009

    tap into the lock and unlock terminals(wires) i suggested in previous post with test light to confirm,

    which is bigger thicker wires in left hand connector from your picture and my scematic

    X13252 connector

  • Steve Hurc
    Steve Hurc Aug 03, 2009

    yes pin 2 is the earth (common) wire for lock and unlock which is blue/grey(BL/GR)

    pin 1 lock is (SW) BLACK

    pin 9 unlock is (WS)white

    try your module hooked up to how you said in last post it all depends on your aftermarket module is able to put out enough power on lock and unlock wire(amps/load).if it hasent door lock motors may not work properly or at all then measure voltage on unlock and lock wire from aftermarket module if 12v on lock and 0v on unlock or vise versa need to put these on middle connector on bcm these are the low voltage request so bcm does switching of high voltage to door locks so you dont burn out aftermarket module

  • Steve Hurc
    Steve Hurc Aug 03, 2009

    connector X13253 (middle connector) is input from master switch (pin 1 on switch colour RT/GN/GE pin 19 on BCM) eg power = lock request, no power = unlock request

    BL =BLUE

    BR= BROWN

    GE =YELLOW

    GN =GREEN

    GR= GRAY

    OR= ORANGE

    RS =PINK

    RT= RED

    SW =BLACK

    VI= VIOLET

    WS= WHITE

  • Steve Hurc
    Steve Hurc Aug 03, 2009

    it should be these colours looks like you have a wire wrong in picture

    yes pin 2 is the earth (common) wire for lock and unlock which is blue/grey(BL/GR)
    pin 1 lock is (SW) BLACK
    pin 9 unlock is (WS)white

  • Steve Hurc
    Steve Hurc Aug 03, 2009

    in description of operation the above colour wires and pin locations are correct but after carefully looking at wiring diagrams the black wire might be earth or power supply

    and the white is a power or earth

    and the blue/grey is switchable power and earth which is controlled by transistor in BECM (chip) by input received from central manual switch which is a 12V on,lock or 0V off, unlock signal to BECM via wires in centre connector of BECM

  • Steve Hurc
    Steve Hurc Aug 03, 2009

    which i also listed pin locatin in connector X13253 (middle connector) is input from master switch (pin 1 on switch colour RT/GN/GE, RED/GREEN/YELLOWpin 19 on BCM) eg power = lock request, no power = unlock request

  • Steve Hurc
    Steve Hurc Aug 03, 2009

    power your module from pin 10 in X13252 connector, red= +power

    earth wire from your module, black= ground, to good body earth of vehicle



    have these two wires disconnected, green= unlock and blue=lock so you can test what comes out of your module on these wires with test light to check for power, then also when operated, if no power then check for continuity to earth and then when operated with Ohms meter.

    then put the wire with 12V output from your module (blue or green) to pin 19 in middle connector of BCM connector X13253, doors should then lock if closed and keys out of ignition.



    you may also need to put your yellow/black=common line wire to earth but check for power on this wire 1st and then also when operated( press remote buttons)



    removing 12v from wire in BCM middle connector X13253 pin 19 should then unlock doors.










  • Steve Hurc
    Steve Hurc Aug 03, 2009

    or pin 9 in bcm connector X13252 is the output to door locks for lock signal - blue=lock

    pin 2 in bcm connector X13252 is the output to door locks for unlock signal - green= unlock
    pin 1 in bcm connector X13252 is the output to door locks for central arrest signal - yellow/black=common line
    when connected like this if it doesnt work you may need to cut these 3 wires out of bcm then try

  • Steve Hurc
    Steve Hurc Aug 03, 2009

    unfortunatley this is a long and slow process due to not knowing what the aftermarket module outputs on the lock and unlock wires power all the time or earth taken away on one of the 2 or a momentary power, earth or open circuit?

    plus trying to understand system operation and wiring diagrams of this vehicle when i have found 2 different systems were fitted to these vehicles but terminal locations are same functions

    description of operation is different to how wiring diagram is drawn for the lock and unlock wires they change (lock is unlock & unlock is lock)

Hi ,to do this you need a wiring diagram of the alarm/cenral locking system the car uses a CAN-Bus system so unless you have an oscilloscope you won`t be able to see the pulses as they are in microseconds,if the car is under 3 years old give it back to the dealer to repair free of charge if not find a good BMW garage with dealer ship level diagnostics (Winstar BMW) you can then go into the system and find any fault codes and actuate the different circuits to find the fault.Be warned if you power probe the wires you will cause thousands of pounds worth of damage to the CAN network and potentially cause an electrical fire,if your not sure ,Take it to an expert it will save you time and money in the long run

If you cannot lock or unlock the doors, the first thing I would check/replace would be the battery in the key fob/remote. You may have to take it to the dealer to have a reprogram done to the module which controls the door locks.

You can either use an ohmmeter and hook one end up to the door wires, and find the keyless entry box that is usually located under the dash panel and find out which wires are for what.

The answer is quite simple: I take a close look at all wires on the other door. I measure resistance to each wire on the WORKING side. I go back to the broken side and detirmine the bad wire. It takes time Kimosabe. But that my friend is the secret to how it is done.

    If you see in my original answer - your doors use a - pulse trigger, a test light is not sufficient, you will need a multimeter capable of measuring 12vDC.



    Test lights only show the presence of voltage. Not how much.



    Good luck!

Is this a BMW factory kit you are installing? if not you are going to need a factory wiring diagram, but short of that locate the power lock relay, that is where you need to tap in for an aftermarket system. if this is a aftermarket system please give name and maker of system.

I don't know what you have already covered but, Generally to trace a wire, first find the wire on a schematic that lists color code and color changes along its pathway. What I have always liked least about schematics is that they tell you a wire or component is there but not where. (none I've ever seen do) It seems that from what I can see that you have written, there is no power inside the door...The most common problem that causes that is where the door meets the body at the hinge end, there is a rubber boot containing the harness...most wires break right there. Sorry I can't offer much more but to diagnose electrical work without actually being there and doing testing is next to impossible (it's not easy even in person) And, entry systems are generally considered part of your security system and often are kept "secret" or anyone could defeat them. Then, tracing has to be done inch by inch.
Good luck.

Whne you run out of help let me know and I will tell you where to hook up the wire, there is a control module you need to connect to to operate all locks.

It sounds like you are trying to find a wiring schematic to trace the electric door lock system?
If so, the link below will lead you to a web site that will show you the wiring.
Good luck, let me know.

Hi there ,

The basic diagram below should allow you to connect the keyless entry module, it is for US/CA models:

Legend: ITEM - WIRE COLOR - |POL| - WIRE LOCATION
| 12V red/wht or red |+ | ignition harness
| STARTER blk/yel or grn/blk |+ | ignition harness
| IGNITION green |+ | ignition harness
| SECOND IGNITION pur/wht or purple |+ | ignition harness
| POWER LOCK white/red |+ | factory alarm plug *1
| POWER UNLOCK blue/red |+ | factory alarm plug *1
| PARKING LIGHTS + gry/pur, gry/ye l *3 | headlight switch
| PARKING LIGHTS - blue/green (hazards) factory alarm plug *1
| HEADLIGHTS yellow headlight switch
| DOOR TRIGGER|*4 factory alarm plug *1
| DOME SUPERVISIO |comes on with unlock
| TRUNK/HATCH PIN brown/white |- | factory alarm plug *1
| HOOD PIN| purple/green |- |*6
| FCTRY ALARM ARM *7
|FCTRY ALRM DISAR *7
| TACHOMETER| black instrument cluster *2
| BRAKE WIRE| blue/red |+ | at brake pedal switch
| HORN TRIGGER brown/red |- | steering column
| WIPERS blk/gry and blk/blu |- | steering column
| LF WINDOW UP/DN|blk/wht - pur/wht |A |body electr control mod *5 |
| RF WINDOW UP/DN|blu/grn - yel/grn |A |body electr control mod *5 |
| LR WINDOW UP/DN|blk/yel - blu/grn |A |relay module *5 |
| RR WINDOW UP/DN|wht/yel - blu/red |A |relay module *5 |

NOTES: This vehicle is equiped with the EWS II immobilizer system that need to be bypassed when adding a remote start. Use DEI module 555B. *1 The alarm plug is a black 12 pin plug located just behind the glove box. It is mounted with the pins facing you atop a vent just to the left of the body computer. Other wires at the alarm plug are: 12V- red/white; Accessory- purple/white; Siren- black/blue; Ground- brown/orange. Do not use the power sources at the alarm plug to operate high-current devices. The other side of the siren wire is mounted in a 2 pin plug at the passenger rear corner of the engine compartment. The other wire in the plug is a brown ground wire. DEI recommends attaching the siren at this point. *2 The wire is located in a white connector behind the instrument cluster. Do not unplug the white connector with the ignition on or turn the ignition on with the plug disconnected. *3 These wires are the separate left and right parking light wires. Use both wires and isolate each. *4 Door triggers are brown/gray for the drivers front door, brown/blue for the passenger front door, and brown/white for the rear doors (if equipped). Use all three wires and diode isolate each. *5 The body electronics control module and the relay module are located behind the glove box. When using a 530T and locking and unlocking with the key will cause the windows to travel full direction. The 529T will not alter the factory operation. *6 Located in a single pin connector next to the factory alarm plug. *7 If equipped with a factory alarm, the alarm will be plugged into the factory alarm plug. The only way to arm and disarm the factory alarm is with the factory remote. If your planning on using the 8360 pre-wired alarm harness the factory alarm must absent or removed.

From 12Volts.


If that is not enough, then the best thing to do is getting a complete wiring diagram for your car.
If you register onto this forum you can get a free wiring diagram for the 318Ti 1996-US model, that is not much different from the europena one (on UK models driver side features are inverted).

A good thing to do when you decide to DIY your vehicle is also grabbing the repair manual for your model, with full diagram, and illustrated step by step repair procedures: BMW Automotive Repair Manuals.

If my comment had been helpful, then please do not forget to leave feedback, answering, researching and typing takes its time.

thanks.

    If this vehicle came with no keyless entry as default , then there may be no ready wiring harness.

    You need to pass wiring to connect the module to Ground, Alarm, Ignition, and door lock switches.

    I can see if I will find more on this specific model.

    I checked the wiring manual for a 1986 BMW series 3 (325, 2.5 engine war different, but wiring diagram for in-car features is similar). There appear to be no ready connector for remote keyless entry.

    If there is an alarm you need to bypass the alarm as previously instructed. Alarm connector is located below the injection on the steering column.

    If there is no alarm, just connect the door switch harness , download manual from forum indicated on previous comment and connect the central lock illustrated at page 50 or so.

    Regards.

    Note :when I said '' door switch harness'' in my last comment I meant connect straight to the central lock if this car has a central lock already (it should).

  • Ginko
    Ginko Jul 25, 2009

    You test the wires with a voltmeter like this: Schumacher BT-50 Digital Voltmeter

    If you want precise indications upload a big picture of the wiring diagram you scanned.

    You can upload the pictuer here:

    and give us the final link afterward.

  • Arjun Komath Jul 18, 2009

    The 1993 installation instructions show two steps to connect the module: "Locate
    the 12-pin connector secured to the main wire harness with blue tape. Plug the 12-pin
    connector of the keyless entry wire harness into the main harness 12-pin connector."
    "Plug the keyless entry 14-pin connector into the keyless entry control unit."

SOURCE: keyless entry on honda civic 2006 not working

The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

I have a 96 ford conversion van with a 600 plus addon keyless system and need to program new keyless remots , need to know how to get system in program mode.


Hi.

To program ( or reprogram ) a keyless entry remote transmitter into the remote keyless entry module, perform the following steps:

1. Turn the key to ON or ACC and short the two terminals of the program connector, a two-pin connector located below the driver's side of the instrument panel at the base of the steering column. All doors should lock and then unlock.
2. Press any button on each keyless entry remote transmitter in turn. All doors should lock and then unlock. If the door locks do not respond, press the button again (up to three times maximum with the same keyless entry remote transmitter). If the door locks still fail to respond, go to Pinpoint Test A.
3. Repeat Step 2 to program additional keyless entry remote transmitters into the remote keyless entry module (up to four keyless entry remote transmitters maximum).
4. Turn key off.
5. Remove the short from the program connector. All doors should lock and then unlock.
6. Verify that the keyless entry remote transmitters have been successfully programmed by pressing the LOCK or UNLOCK button on each one, and observing that the system responds by locking and/or unlocking the doors.


I hope this helps you.

Thanks!

Unlock doors without keys


The vehicle must be equipped with 'Keyless Entry" system. You didn't mention if your vehicle is equipped with it. If it isn't, there are 'after market' systems which you can install 'do-it-yourself', provided your door locks are electrical. If your door lock are 'manual', you cannot install a "keyless entry' system without replacing the door lock/unlock actuators & main wiring harnesses.

1999 Chevy Tahoe Door wiring diagram


I am not sure exactly where to get your info for free, but have another solution. The drivers door holds all you need. The door panel needs to be removed and then reconnect the power door lock switch. Then just locking and unlocking the door will trigger the actuator to move, allowing you to find it and the wires connected to it. Disconnect the wires and plug in a Digital Multi-Meter into the plug on the wire end and hit the lock and the unlock buttons to find which polarity to which wire unlocks the door and to lock it would be in reverse. Then he can wire the keyless entry into the truck via these wires and can use wire-taps which will pop over the wires in the truck and allow him to add the keyless entry w/o cutting wires. :D Have fun

Key Pad Entry does not work


does the key pad light when you press a button at night? If yes, the fuse is ok.
Do you have the plastic card with the permanent code in your owner manual packet? If yes, tryit.
report back.

Keyless Entry The keyless entry keypad is hardwired to the GEM. The GEM interprets the inputs from the keyless entry keypad and then controls the associated operation. The keyless entry keypad will be illuminated for five seconds when any button is pressed. Additionally, it will request the illuminated entry feature to turn the courtesy lamps on. If a lock all doors code is entered, the illumination will turn off, as well as request the illuminated entry feature to turn off the courtesy lamps. When pressed, the keyless entry keypad supplies the ground signal to the GEM or the GEM receives a signal from the keyless entry remote transmitter. Then the GEM outputs a ground signal to the appropriate lock or unlock relay which supplies the power to the actuator to lock or unlocks all doors, including the luggage compartment. The keyless entry remote transmitter also unlocks the liftgate or activates the panic alarm by sending a signal to the GEM.
