Programming a Remote Head Key for 2007 Lincoln MKZ

Important: This procedure allows you to program a spare remote head key using the vehicle’s ignition system. To perform this successfully, you must have two valid, previously programmed keys. If fewer than two working keys are available, this process cannot be completed manually. You will need three keys: two already programmed and one new, unprogrammed key. Follow the timing carefully between each step. Read the entire guide before starting. If any step is missed, restart the process from the beginning after a 10-second pause.

Remote Head Key Programming Steps:

• Step 1: Make sure all doors are closed and the vehicle is turned off.
• Step 2: Insert the first programmed key into the ignition.
• Step 3: Turn the ignition from OFF to ON (do not start the engine).
• Step 4: Leave the ignition in the ON position for at least 3 seconds, but no more than 10 seconds.

• Step 11: Turn the ignition from OFF to ON.
• Step 12: Leave the ignition ON for at least 6 seconds to complete the programming.
• Step 13: Turn the ignition OFF and remove the newly programmed key.
• Step 14: Test the new key by starting the vehicle. Ensure that the engine starts successfully.
• Step 15: Confirm that the remote functions work, such as lock and unlock, if the key includes integrated remote features.
