Programming Guide for 1997 Mercury Sable Keyless Entry Remote Fob

Important Notice: The 1997 Mercury Sable allows onboard programming of keyless entry remote fobs using a timed ignition cycle. During this process, all remotes must be programmed in the same session. If any remotes are not included, they will be erased from memory and must be reprogrammed.

Programming Instructions:

• Step 1: Sit in the driver’s seat and ensure all doors are securely 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 five times, ending the fifth turn with the key in the RUN position. The ignition cycles must be 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 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 once more, confirming the end of the programming session.
• Step 8: Remove the key from the ignition and test each remote to ensure the lock and unlock functions are working correctly.

Additional Considerations: All remotes must be programmed in the same session. Any remote not included will be erased and will need to be reprogrammed. Be mindful of the timing. If you take too long between steps, the system will automatically exit programming mode, requiring you to start over. Ensure the batteries in the remotes are functional before beginning the programming process to avoid programming failures.
