    don't know if it will work on yours but try closing and locking all the doors, lock drivers door with the key and then unlock...also with key. On some systems it re-sets the system.

I had the same problem with my 2007 Sahara Unlimited. I'll make a long story as short as possible. For a number of years my son ran a Chrysler / Jeep dealership and I contacted him (I bought my Jeep from him before he got out of the business) and he told me this is a sporadic problem with the Wrangler line. To the point of calling him I had tried everything and nothing worked...insert key, turn, nothing...all electrical worked, lights, power windows, radio, etc, etc. He told me to disconnect the negative power connection on the battery for a second or two then re-attach. Insert key, engine starts, everything works as advertised.

Essentially, my son told me this "re-boots" the system. For whatever, and to his knowledge, never explained by Jeep, this fix works but no idea as to why it happens in the first place.

Hope this is of some help...though I suggest that there may be more "fixes" to this problem.

Regards...

Keyless entry wont unlock


TThere is probably a problem with the door unlock relay or the passenger door module. The passenger door modules on Jeep Cherokee have had a lot of problems and there are a couple of Technical Service bulletins published by the manufacturer as a result of these failures.

I have a 2000 ford mustang. Suddenly my keyless entry remote stopped working. I replaced the battery and turned the off and on 8 times and the locks cycled. after which i pushed the unlock but nothing...


The keyless entry system is controlled by the (GEM) - generic electronic module .
Keyless Entry The electronic door lock system has two main components:
  • generic electronic module (GEM)(14B204)
  • keyless entry remote transmitter (15K601)
  • NOTE: Battery power and ground must be remove before disconnecting the GEM connectors to avoid setting false codes.
    Power Locks Operation The power locks feature allows the customer to lock and unlock the doors via momentary switches located on the driver and passenger door. When the GEM detects a momentary press of the driver or passenger lock button, the GEM will supply power to the driver or passenger lock actuators for approximately 250 ms from relays internal to the GEM. When the GEM detects a momentary press of the driver or passenger unlock button, the GEM will supply power to the driver or passenger unlock actuators for approximately 250 ms from relays internal to the GEM.
    Remote Keyless Entry Door Locks Operation The remote entry feature allows the customer to unlock the driver door, unlock all doors, and lock all doors using a valid remote transmitter as long as the ignition switch is not in RUN or START. The driver door is unlocked whenever the GEM detects a valid remote transmitter unlock transmission. All the doors are unlocked when the GEM detects a second valid remote transmitter unlock transmission within three seconds of the first transmission. All the doors are locked when the GEM detects a valid remote transmitter lock transmission. If the GEM detects a second valid remote transmitter lock transmission within three seconds of the first transmission, the doors will lock again, the horn will sound for 20 ms and the parking lamps will flash for 200 ms to indicate the doors are locked. If the GEM detects the driver or passenger door is ajar during the second lock transmission, the doors are locked again and the horn is sounded twice. If the GEM detects a valid remote transmitter lock transmission within three seconds of detecting a valid remote transmitter unlock transmission, the GEM will lock all the doors
    • The doors do not lock/unlock using the remote transmitter
    • Ignition switch.
    • GEM.
    • Remote transmitter.
    • Remote transmitter batteries.
    • GO to Pinpoint Test C .
    You followed the program instructions to the letter ? Programming -Keyless Entry Remote Transmitter NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.
    NOTE: All previous transmitter identification codes (TIC's) will be erased when programming mode is entered.
    NOTE: To program (or reprogram) the keyless entry remote transmitters into the generic electronic module (GEM)(14B204), perform the following steps.
    1. Turn the ignition from OFF to RUN eight times within 10 seconds, ending in RUN. If the GEM has successfully entered program mode, it will lock and unlock all the doors.
    1. NOTE: The first TIC must be entered within 7.5 seconds of entering the program mode and additional TICs must be entered within 7.5 seconds of the first TIC. The programming mode is exited whenever the timing constraints are not met.
      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.
    1. If the door locks do not respond for any keyless entry remote transmitter, wait for several seconds and press the button again.
    1. Turn the ignition switch to the OFF position, or wait up to five minutes after step 1, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the GEM will lock and unlock all the doors one last time.
    1. Take an have the vehicle checked for DTC'S

Keyless entry does not unlock doors, open trunk, or start vehicle (remote start built onto keyless entry). Battery is new in BOTH remotes and neither one works. Could a fuse in vehicle be bad? Secondly,...


RFA / MOD fuse 10amp . location - insturment panel fuse box. Fuse Block - I/P
Right side of the I/P, behind the access panel
If the fuse is good your best bet would be to take it to a qualified repair shop , that doesn't mean the dealer . Lot of good independant repair shops around , just have to check the yellow pages.
Do you know what DTC'S are ? diagnostic trouble codes ! Not only the ones for the engine management system OBD 2 . There are also DTC'S for the remote keyless entry system , BCM - body control module. You need a factory or professional scan tool to view this codes
DTC B3101

DTC B3103
DTC B3106

The remote control door lock receiver (RCDLR) communicates with the body control module (BCM) through the keyless entry serial data circuit. When any button on the keyless entry transmitter is pressed, the transmitter sends a signal to the RCDLR. The RCDLR sends a lock, unlock, or panic alarm request to the BCM, depending on which button is pressed on the transmitter. The BCM receives the message and performs the appropriate function. The BCM also uses the keyless entry serial data circuit in order to communicate with the RCDLR when programming transmitters. Do you know what serial data circuits are ?

This is what the factory manual said as to the location of power steering fluid reservoir ! Not much help , you would do better googling it.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine

I don't have a manual for my 2004 lincoln Avaitor but would like to know how I can change the code on the drives door key pad


KEYLESS ENTRY SYSTEM With the keyless entry keypad, you can: • lock or unlock the vehicle doors without using the key. Your vehicle has a factory set 5 digit code that operates the keyless entry system. You can also program your own 5 digit personal entry code. The factory-set code is located: • on the owner's wallet card in the glove compartment • or at your dealer. When pressing the controls on the keyless entry keypad, press the middle of the controls to ensure a good activation. This system will disable the power door lock controls. These will not work until the vehicle is disarmed. Programming your own personal entry code To program your own code: 5. Enter factory set code (keypad will illuminate when pressed). 6. Press 1/2 control within five seconds of step 1. 7. Enter your personal 5 digit code. Enter each digit within five seconds of previous one. 8. After the code is entered, the locks will cycle, confirming that the new code has been set. Do not set a code that includes five of the same number or presents them in sequential order. Thieves can easily figure out these types of codes. Your personal code does not replace the permanent code that the dealership gave you. You can use either code to unlock your vehicle. If a second personal code is entered, the module will erase the first personal code in favor of the new code. Locks and Security 149 Locks and Security If you wish to erase your personal code, use the following instructions: 1. Enter factory set code. 2. Press 1/2 control and release. The system will now only respond to the factory set code. Anti-scan feature The anti-scan feature prevents repeated attempts at arriving at a valid key code. The keyless entry pad is disabled for 1 minute after 7 unsuccessful attempts (35 consecutive button presses) at entering a valid key code. The keypad will flash during this 1 minute mode. However, the 7/8 and 9/0 controls will still lock the vehicle. Anti-scan will be turned off after: • one minute of keypad inactivity. • the remote entry transmitter UNLOCK button is pressed. • the ignition is turned to the ON position. Unlocking the doors with the keyless entry system To unlock the driver door, enter either the factory set code or the personal code (each digit must be pressed within five seconds of the prior digit). The interior lamps will also illuminate. To unlock all doors, enter the factory set code or personal code (driver door unlocks) and press the 3/4 control within five seconds. Locking the doors with the keyless entry system It is not necessary to enter the factory or personal code prior to locking all doors. To lock the doors: • with the driver's door closed, press the 7/8 control and the 9/0 control at the same time.

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.

Fuse or what


Your multifunction switch on the steering column controls your exterior lights. The GEM module controls the interior lights and other stuff. If bad, it would not blow fuses. WHich fuse blows?
Your Ford dealer might be familiar with this issue, so call the service dept and ask them and get a quote. It may be wiring.
reoprt back.

  • The high beams are inoperative
  • Circuitry.
  • Multifunction switch.
  • Go To Pinpoint Test C .


--------------------------------------------------------------
Principles of Operation
Generic Electronic Module (GEM) The generic electronic module (GEM) receives inputs from the following:
  • door ajar switches
  • liftgate ajar switch (wagon)
  • liftgate glass switch (wagon)
  • headlamp switch
  • keyless entry keypad switches
  • the powertrain control module (PCM) (vehicle speed signal)
  • ignition switch
  • remote keyless entry transmitter
The GEM uses these inputs to control the output to the battery saver relay and interior lamp relay. Both relays are integral to the central junction box (CJB) and cannot be accessed directly.
Interior Lighting Systems The GEM grounds the battery saver relay and interior lamp relay coils when any door ajar switch or the headlamp switch is closed. The interior lamp relay then supplies power to the interior lamp circuit. Vehicle speed must be less than 15 kph (9 mph) for the GEM to ground the interior lamp relay. The interior lamps will remain illuminated for a period of up to 25 seconds after all doors are closed or until the ignition is switched from the OFF position, or the GEM receives a vehicle speed signal. Actuating the interior lights from the headlamp switch will operate at any time.
Illuminated Entry Illuminated entry is activated when a keyless entry keypad switch provides ground on the GEM input or when the GEM receives an unlock signal from the remote keyless entry key fob. The GEM then provides ground to the battery saver and interior lamp relay coils. Illuminated entry is deactivated when the GEM receives a lock signal from the remote keyless entry key fob or if the GEM receives ground inputs from the keyless entry keypad switch lock code. Illuminated entry will also be deactivated when the GEM receives input voltage from the ignition switch.
Battery Saver The battery saver is activated when the GEM is not receiving voltage input from the ignition switch (off position). The GEM will then provide ground to the battery saver relay coil for a maximum of 30 minutes depending on the state of the interior lamp switch inputs to the GEM. The energized battery saver relay switches voltage to the demand lamp circuit and the interior lamp relay coil. After time-out, the GEM removes ground to the battery saver relay disabling the demand lamp circuit.
Puddle Lamps The puddle lamp relay operates reverse from the battery saver relay and the interior lamp relay. The puddle lamp relay coil receives voltage when the ignition switch is in the START or RUN position, which disables the circuit to the puddle lamps.
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.
