How do I replace the battery in my Ford key?

The key fob uses one coin-type three-volt lithium battery. For instructions on how to replace the battery in the key fob, refer to your ​Owner's Manual​ under Keys and Remote Control.

Notes: 

  • Do not wipe off any grease on the battery terminals or on the back surface of the circuit board.
  • Refer to local regulations when disposing of batteries.
  • Replacing the battery does not erase the programmed key from the vehicle. 

If you need assistance, take all your keys to your Ford Dealer.
