Losing the ability to remotely control your 2008 Ford Fusion can be a major inconvenience. Often, the culprit is a dead key fob battery, but sometimes, even after replacing the battery, your key fob might still not work. This is often due to the key fob losing its programming to your vehicle. Luckily, reprogramming your 2008 Ford Fusion key fob is a straightforward process you can do yourself, saving you a trip to the dealership. This guide will walk you through the steps for both remote-only programming and programming for remote key combos, ensuring your key fob is functioning perfectly.
Programming Your 2008 Ford Fusion Remote (Remote Only)
If you have a standard key fob remote for your 2008 Ford Fusion, follow these simple steps to program it. Make sure you have all your remotes for the vehicle before starting, as you’ll need to program them all at once.
-
Begin by turning your ignition from the OFF position to the RUN position rapidly, eight times within a 10-second period. Ensure the eighth turn ends in the RUN position. You should hear your door locks cycle; this confirms that your Fusion has entered programming mode. (OFF is when you can remove the key; RUN is just before starting the engine).
-
Within 20 seconds of the locks cycling, take your first keyless remote and press any button. The door locks should cycle again to confirm that the remote has been successfully programmed.
-
If you have additional remotes to program, repeat step 2 for each one. Make sure to do this within 20 seconds of the previous remote programming confirmation.
-
Once you have programmed all your remotes, turn the ignition to the OFF position. The locks will cycle one last time, indicating that the programming mode has ended. Test each remote to ensure they are all working correctly.
Programming Your 2008 Ford Fusion Remote Key Combo
For 2008 Ford Fusion models equipped with a remote key combo (where the remote is integrated into the key itself), the programming process involves the transponder chip and requires two previously programmed original Ford keys.
-
Insert your first previously programmed, coded key into the ignition.
-
Turn the ignition from the LOCK position to the RUN position. Keep it in the RUN position for at least 3 seconds, but not longer than 10 seconds.
-
Turn the ignition back to the LOCK position and remove the first key.
-
Within 10 seconds of removing the first key, insert your second previously programmed, coded key into the ignition.
-
Turn the ignition from LOCK to RUN again, holding it in the RUN position for 3 to 10 seconds.
-
Return the ignition to LOCK and remove the second programmed key.
-
Now, within 20 seconds, insert the new, unprogrammed key (this could be a new key or a valet key) into the ignition.
-
Turn the ignition from LOCK to RUN and hold it in the RUN position for at least 6 seconds.
-
Remove the newly programmed key from the ignition.
After these steps, your new key should be programmed. If it wasn’t successful, repeat steps 1-4. If only the remote portion didn’t program but the key starts the car, perform the “Remote Only” programming procedure mentioned above to program the remote functions of your remote head key.
By following these instructions, you can address key fob issues for your 2008 Ford Fusion, whether it’s due to a dead 2008 Ford Fusion Key Fob Battery requiring reprogramming after replacement, or simply adding a new remote to your vehicle.
