Lost your key fob or need to program a new one for your 2008 Ford Fusion? You’re in the right place. Programming your key fob yourself can save you time and money compared to going to a dealership. This guide provides straightforward instructions for programming both the remote function and the transponder chip for your 2008 Ford Fusion Key Fob.
Programming Your 2008 Ford Fusion Remote (Remote Only)
These instructions are for programming the remote control functions of your key fob, such as locking and unlocking your doors and remote start (if equipped). Make sure you have all the remotes you intend to use with your vehicle before starting this process, as you will need to program them all at the same time.
-
Enter Programming Mode: Start by turning your ignition key from the OFF position to the RUN position rapidly eight times within a 10-second period. The eighth turn should end in the RUN position. You’ll know you’ve successfully entered programming mode when the door locks cycle (lock then unlock). The OFF position is where you can remove your key from the ignition, and the RUN position is just before you would start the engine.
-
Program the First Remote: Within 20 seconds of the door locks cycling, press any button on the first keyless remote you want to program. The door locks will cycle again to confirm that the remote has been programmed.
-
Program Additional Remotes (If Applicable): If you have more than one remote to program, you have 20 seconds after the locks cycle to press any button on the next remote. Again, the door locks will cycle to confirm programming. Repeat this step for every additional remote you need to program.
-
Exit Programming Mode: Once you have programmed all your remotes, turn the ignition key to the OFF position. The door locks will cycle one last time to indicate that you have exited the programming mode.
Programming Your 2008 Ford Fusion Remote Key Combo (Transponder Chip)
These steps are specifically for programming the transponder chip within your remote key combo. This chip is essential for starting your 2008 Ford Fusion. Important: To program the transponder chip, you must have two previously programmed, original Ford keys that currently work with your vehicle. If you do not have two working keys, you will need to visit a locksmith or dealership for programming.
-
Insert First Working Key: Insert your first previously programmed, working Ford key into the ignition.
-
Turn to RUN Position (First Key): Turn the ignition from the LOCK position to the RUN position. Keep the key in the RUN position for at least 3 seconds, but no longer than 10 seconds.
-
Remove First Key: Turn the ignition back to the LOCK position and remove the first key.
-
Insert Second Working Key: Within 10 seconds of removing the first key, insert your second previously programmed, working Ford key into the ignition.
-
Turn to RUN Position (Second Key): Turn the ignition from the LOCK position to the RUN position with the second key. Hold it in the RUN position for at least 3 seconds, but no longer than 10 seconds.
-
Remove Second Key: Turn the ignition back to the LOCK position and remove the second working key.
-
Insert New Key: Within 20 seconds of removing the second working key, insert the new, unprogrammed key (this could be a new key or a valet key) into the ignition.
-
Turn to RUN Position (New Key): Turn the ignition from the LOCK position to the RUN position with the new key. Keep it in the RUN position for at least 6 seconds.
-
Programming Complete: Remove the newly programmed key from the ignition. Your new key should now be programmed to start your 2008 Ford Fusion.
Troubleshooting: If the new key does not successfully program, repeat steps 1-9. If the remote portion of your remote key combo does not program after these steps, but the key starts the vehicle, follow the “Remote Only” programming instructions above to program the remote functions.
By following these instructions, you can program your 2008 Ford Fusion key fob and remote key combo efficiently and get back on the road.
