Central locking failed on volvo C30

Central locking normally by keyless entry, just stopped working, system seems to be locking and unlocking itself very fast, although the door will not open, when opening with the key the alarm goes off. Tried another remote, still the same. Remote batteries are in good condition.

Disconnect the battery from your car (negative cable only) overnight. Make sure you have your radio reset code before doing so.

Then reconnect after 10 hours, and make sure you have remote handy as alarm may go off. Then if that doesnt fix it, go to driver door, then insert master key, pull up on handle first all the way and hold it. Then turn the key slowly all the way so the doors unlock and continue turning the key. This will reset the central locking system as yours may have gotton stuck. then remove key let go of handle, open door and try to lock and unlock doors from switch inside car.

Then try remote. It should work, this is what the dealer will do and charge you about $350...if it doesnt work order a new remote b/c yours may have become damaged by liquid or dropping?

Have a great day,

Thanks,

Mark

SOURCE: BMW Keyless Entry not working

hi, to program the keys to the vehicle is quite simple

1) open the vehicle, sit inside and close the door

2) insert the key in the ignition and turn to position 1 so that just the air bag light illuminates

3) press and hold the unlock button on the key and remove the key from the ignition (do not release the unlock button)

4) while still holding the unlock button with the key removed press the lock button 3 times

5) release the unlock button on the remote and the door locks should lock and unlock if the proceedure has been carried out correctly

6) to program any other key(s) press and hold the unlock button on remote and again press the lock button 3 times but do not insert it into the ignition or turn the ignition on as done previous.

you may want to print these instructions and read them a few times before proceeding, if you muck up the process while programing keys, no harm will be done, you just have to start the process over. hope this is of some help, regards mark.

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.

SOURCE: Power door locks do not work with keyless remote control

There are two multiplex control units - one on the driver side and one onthe passenger side - which one did you unplug? The one on the driver side is the main "Brain" while the other one is the one that houses the keyless reciever. According to the service manual, any troubleshooting of this system must begin with the one on the driver side. It can get quite involved because Honda does not provide actual troubleshooting (symptom) charts, just descriptions of the electrical connectors and what conditions should be present at each conector pin under what system condition. (each pin has to be tested to determine what is malfunctioning) The system is not capable of outputting fault codes of any kind.

I went through programing as far as lock recycling but wont go any further


Remote Transmitter Programming NOTE: All keyless entry remote transmitters must be programmed at the same time.
NOTE: Programming (or reprogramming) the keyless entry remote transmitters into the central security module can be accomplished using a diagnostic tool or by carrying out the following steps.
  1. Turn the ignition switch from OFF to RUN eight times within 10 seconds, ending in RUN. If the module has successfully entered program mode, it will lock and then unlock all doors.
  1. Within 20 seconds, press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed. Repeat this step for each transmitter.
  1. If the door locks do not respond for any keyless entry remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Inspection and Verification.
  1. Turn the ignition switch to the OFF position, or wait up to 20 seconds after Step 2, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the doors will lock and unlock one last time to confirm.

Mervia. Why is central locking not locking any door?


It's only an educated guess. If all other locks switches are working it' either the switch panel itself or an electrical short. Switches are popular, get it checked first

My keyless entry for my 2008 Volvo s 40 won't work. I've tried replacing the battery but it still doesn't work. Anything I may can do before spending money on a new key.?


How are you trying to open the door , button on key fob ? With this system you can pull up on the drivers handle an it activates Antennas in the external side door handles (C30/C70 front doors, S40/V50 rear doors)
  • Antennas in the passenger compartment and cargo compartment
  • An antenna in the rear bumper
  • Quick lock motors in the lock units in the side doors
  • The remote keyless entry (RKE) receiver receives a signal from the key
  • The switch in the clutch pedal (manual transmissions) or a signal from the brake pedal switch via the central electronic module (CEM) (automatic transmissions)
  • Key-in switch.
  • Switch in door handle and lock button on handle .
    If a door handle is pulled outward, a switch closes that wakes up the system and activates the antennas in the handles on the side where the handle has been pulled out. If a valid key is within a radius of approx. 1.5 metres from the handle, the relevant door will open and the vehicle will unlock one or several doors. Which doors are unlocked depends on the settings for the system. The vehicle can also be unlocked if the handle is affected on the tailgate.

    You can't figure out thing's without knowing how there work , what controls them . In this case a control module .
    Principles of Operation

    Power Door Locks
    The central security module controls the power door lock and keyless entry system. The lock and unlock operation is carried out by supplying ground to the central security module from the door lock control switch. The normal path of the actuators is to ground through the central security module. The door lock control switch will lock and unlock all doors by grounding the appropriate circuit to the central security module. The central security module then supplies power to the appropriate common actuator circuit to lock or unlock all doors.
    Plus we don't guess , we test the electrical circuits with a DVOM - digital multimeter or a test light . We use a wiring diagram so we know which part of the circuits to test .

    Keyless Entry
    The remote transmitter sends a frequency that is received by the central security module internal antenna. Depending on the frequency received, the central security module will lock all doors or unlock the driver door. If the unlock frequency is received again within five seconds of the first unlock, the central security module will unlock all doors.
    If the frequency received is for the panic button, the central security module will cycle ground to the park lamp and horn. The park lamps and horn will continue to cycle until the panic button is pressed again or the ignition switch is turned to the RUN position or 2.75 minutes elapse.
    Plus we hook up a scan tool that can read codes from the control module , not a code reader for engine codes , won't work ! Need a professional scan tool .Do you know what DTC'S are ? Diagnostic trouble codes !
    Central Security Module Diagnostic Trouble Code (DTC) Index DTC Description Source Action to Take B1309 Power Door Lock Circuit Short to Ground Central Security Module Go To Pinpoint Test C . B1341 Power Door Unlock Circuit Short to Ground Central Security Module Go To Pinpoint Test C . B1485 Brake Pedal Input Circuit Short to Battery Central Security Module Go To Pinpoint Test E . B1526 Keyless Entry Circuit Short to Ground Central Security Module Go To Pinpoint Test F . B1629 PRNDL Reverse Input Short to Battery Central Security Module Go To Pinpoint Test E . B2276 Less Than Two Transmitters Programmed Central Security Module Go To Pinpoint Test I . B2425 Remote Keyless Entry Out of Synchronization Central Security Module Go To Pinpoint Test I . - All Other DTCs Central Security Module REFER to Section 419-10 .
    • All door locks are inoperative
    • Battery junction box (BJB) fuse(s):
      • 8 (15A).
      • 115 (20A) (Super Crew).
    • Circuitry.
    • Central security module.
    • Go To Pinpoint Test C .

    Seams you lack the knowledge and test equipment to tackle this type of repair . Your best bet mite be to have a qualified repair shop check it out.
    So, without testing i couldn't even begin to suggest what mite be wrong . I would only be guessing , as would anyone on here would.

    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!
