Programming Guide for 1998 Mercury Sable Keyless Entry Remote Fob

Important Notice: The 1998 Mercury Sable supports onboard programming for keyless entry remote fobs using a timed ignition cycle. All remotes must be programmed during the same session. If a remote is missed, it will be erased from the system and will need to be reprogrammed.

Programming Instructions:

• Step 1: Sit in the driver’s seat and ensure that all vehicle doors are fully closed.
• Step 2: Insert the key into the ignition switch but 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 the eighth turn in the RUN position. Ensure the cycle is completed quickly and smoothly. Upon successful entry into programming mode, the door locks will cycle (lock and unlock) to confirm the system is ready.
• Step 4: Within 20 seconds, press any button on the first keyless remote fob. The door locks will cycle again to confirm that the first remote has been successfully programmed.
• Step 5: If programming a second keyless remote, press any button on the second remote within 20 seconds of the first remote. The door locks will cycle again to confirm that the second remote has been accepted.
• Step 6: Once all remotes have been programmed, turn the ignition key to the OFF position.
• Step 7: The door locks will cycle one final time, signaling the end of the programming session.
• Step 8: Remove the key from the ignition and test all remotes to ensure the lock and unlock functions are working properly.

Additional Considerations: All remotes must be programmed during the same session. Any remote that is not programmed will be erased and will need to be reprogrammed. Timing is important. If too much time passes between steps, the vehicle will automatically exit programming mode. Check the batteries in each remote before beginning the process to ensure they are functioning properly.
