Ford F-150 Key Fob
Notch At Bottom Left
Insert Flathead Screwdriver
This automotive "how-to" guide was specifically written to assist owners of the 12th generation (2009, 2010, 2011, 2012, 2013 & 2014) Ford F-150 truck in changing a weak or worn out coin cell battery in the key fob remote control.

Owners of other F-Series trucks or other Ford, Lincoln and Mercury vehicles such as the Super Duty F-250, F-350, F-450, Expedition, Explorer, Edge, Escape, E-150, E-250, E-350, Transit Connect, Flex, MKX, MKT, Navigator and Mountaineer may also find these DIY instructions to be helpful.

A replacement key fob coin, "button" or "watch" battery is part number CR2032 from manufacturers such as Panasonic, Sony, GE, Energizer and Philips.

The only tool needed to change the battery is a small flathead screwdriver or a plastic pry bar tool.

You can also use a coin, key or butter knife.

Pry Off Back Halve
Remove Rubber Cover
Pry Out Old Battery
The first step is to locate the notch in the bottom left corner of the combination car key and remote control fob closest to the red "Panic" button.

Insert the blade of the small flathead screwdriver in to the notch and gently pry off the back cover of the fob.

If necessary, remove the rubber cover from the front halve of the fob that creates the water resistant seal to protect the battery.

Gently pull out the old battery with your fingernail or the blade of the small flathead screwdriver.


Panasonic CR 2032 3V
Insert New Battery + Side Up
Replace Rubber Seal
Insert a new CR2032 3 volt battery in to the socket with the positive "+" side facing up.

Replace the rubber seal over the front halve of the key fob.

Line Up Rear Cover
Snap Together Two Halves
Test New Key Fob Battery
Line up the back cover of the key fob and gently snap together the two halves. Make sure that they two halves of the key fob are flush together all the way around.

Test the new key fob battery by standing near your truck and pressing the lock or unlock buttons. If the new battery is working properly, you should see the parking lights flash.
