The keyless entry system consists of the following components:
  • driver door module (DDM)
  • keyless entry transmitter
  • keyless entry keypad
The driver door module (DDM) receives inputs from the digital transmission range (TR) sensor, ignition switch, brake switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).
  • Battery junction box (BJB) fuses:
    • circuit breaker 7 (20A)
  • Central junction box (CJB)
    • 4 (10A)
    • 6 (15A)
    • 8 (25A)
    • 13 (5A)
  • Keyless entry keypad switch
  • Power door lock actuator
  • Luggage compartment release switch
  • Luggage compartment release solenoid
  • Connectors or connections
  • Wiring harness
  • If fuse's good have checked for DTC'S - diagnostic trouble codes .
  • B1526 Keyless Entry Circuit Short to Ground DDM Go To Pinpoint Test E . B1553 Decklid Release Circuit Short to Battery DDM Go To Pinpoint Test B . B1751 Park/Neutral Switch Circuit Short to Battery DDM Go To Pinpoint Test K . B2425 Remote Keyless Entry Out of Synchronization DDM Go To Pinpoint Test L Need a professional grade scan tool to check fro these codes . Not a code reader for OBD2 codes .
  • The doors do not lock/unlock using the remote transmitter
  • Remote transmitter not programmed.

Did you program the new key fob ?

Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.
  1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.
  1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.
  1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.
  1. To exit program mode, turn the ignition to START or wait 7.5 seconds.
  1. NOTE: Failure to wait at least 20 seconds will cause programming failures. Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification

    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

    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!

    Keyless remotes not working


    Try reprogramming the remotes. Here are the instructions for the procedure. Hope it helps. Cobra!
    Programming NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.
    NOTE: To program (or reprogram) the keyless entry remote transmitters into the RAP module, perform the following steps:
    1. Make sure that the anti-theft system is not armed or triggered.
    1. Turn the ignition switch (11572) from OFF to RUN eight times within ten seconds, ending in RUN. If the RAP 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 RAP module will lock and unlock all doors one last time to confirm.

    Keyless entry stopped working on 05 cobalt now i have to unlock door with the key and when i do that the alarm goes off. Help


    Lock all the doors from the inside (with all the doors closed), unlock your driver's door by manually lifting the lock, then press it back down after you are out - this will prevent the alarm from sounding when you use the key to unlock the door.
