The Ford Fusion was among the first cars to feature an integrated key fob that combines the key with the car's remote so that you do not have to carry two separate pieces. The key fob allows you to lock and unlock your car's doors and open the trunk. The equipment also has a panic button to allow you to turn on your car's alarm system by remote. Because the key fob is an electronic device, it is subject to mechanical failure on occasion. Fortunately, fixing a Ford Fusion remote is simple.

Battery Replacement

Step 1

Read through the manual for your Ford Fusion. The manual should list the battery model that your Fusion remote will take. Purchase this battery and set it on your work table next to your Fusion remote so that you can quickly change out the batteries.

Step 2

Look over the key fob for the seam where the fob is put together. This is the point where you will pry the fob apart. This seam should be located on the side of the key fob.

Step 3

Pry the key fob in half by inserting a Phillips-head screwdriver into the seam where the two halves of the fob come together and rocking the screwdriver back and forth to pry the fob open. An eyeglasses screwdriver is a good size for working with the key fob.

Step 4

Remove the button battery from the key fob and place the new battery in the battery cradle.

Place the two halves of the key fob together and press until they snap closed.

Reprogram the Key Fob

Step 1

Turn off the anti-theft system in your car by ensuring that the car is unlocked.

Step 2

Insert the key into the ignition.

Step 3

Switch the ignition back and forth between off and run eight times in 10 seconds. End with your ignition set to run.

Step 4

Press all buttons that you want the car to reprogram.

Switch off the ignition. This should reprogram the key.


  • Ford recommends that you return your key fob to the dealership for service if it ever stops working. Although you can attempt to fix the key fob yourself, doing so can invalidate any key-fob warranty. In the event that you are unable to repair the key fob yourself, your local Ford dealer may be unwilling to repair the key fob. You may instead be required to purchase a new fob.
