How to Program a 2021 Ford Expedition Ignition Smart Chip Key Transponder

Step by Step How to Programming Instructions:

1. Ensure you have two valid keys. If you don’t, you’ll need a locksmith to program a key for you.
2. Insert the first valid key into the ignition switch. Turn the ignition switch to the ON/RUN position for at least three seconds but no longer than 15 seconds. Then, turn the ignition switch to the LOCK position and remove the first key.
3. Insert the second valid key into the ignition switch. Turn the ignition switch to the ON/RUN position within 15 seconds. After 10 seconds, a chime will sound, and the Vehicle Security Light will start flashing. Turn the ignition switch to the LOCK position and remove the second key.
4. Insert the new key into the ignition switch. Turn the ignition switch to the ON/RUN position within 60 seconds. After 10 seconds, a single chime will sound, and the Vehicle Security Light will stop flashing. To indicate that programming is complete, the Vehicle Security Light will turn on again for a few seconds and then turn off. Your new key is now programmed. Repeat this procedure to program up to eight keys.
