2010 Mercury Grand Marquis

Programming Guide for 2010 Keyless Entry Remote Fob

Important Notice: This vehicle supports onboard programming for standard keyless entry remote fobs using an ignition cycle procedure. To maintain proper function, all remotes must be programmed during the same session. Remotes not included during programming will be erased from the vehicle’s memory.

Programming Instructions:

  • Step 1: Sit inside the vehicle with all doors closed. Make sure you have all remote fobs you plan to program before beginning.
  • Step 2: Insert the ignition key into the ignition switch. Do not start the engine.
  • Step 3: Within 10 seconds, turn the ignition key from the OFF position to the RUN position eight times, ending with the key in the RUN position on the eighth cycle. Perform this action quickly and smoothly.
  • Step 4: The door locks will automatically lock and unlock, confirming the vehicle has entered programming mode.
  • Step 5: Within 20 seconds, press any button on the first remote fob. The door locks will cycle again to confirm successful programming.
  • Step 6: If you are programming a second remote, press any button on it within 20 seconds of programming the first. The locks will cycle again to confirm registration.
  • Step 7: Repeat Step 6 for any additional remotes, ensuring each one is programmed within 20 seconds of the previous.
  • Step 8: After all remotes have been programmed, turn the ignition key to the OFF position. The door locks will cycle one final time, indicating that programming mode has ended.
  • Step 9: Remove the key and test each remote to ensure that the lock and unlock features function correctly.
  • Step 10: If any remote fails to operate, repeat the procedure from Step 1, carefully following the timing instructions.

Additional Considerations: All remotes must be programmed in one session. Any remotes not included will no longer function and must be reprogrammed. Precise timing is essential. Delays in ignition cycles or remote button presses can cause the procedure to fail. Check battery condition in each remote before starting. Weak batteries can prevent proper signal transmission.
