It's an easy swop though, so no big headaches or cost. Small 2032 battery, good make.About £3.00p. Dave B. I rarely use the fob and use keyless most of the time, as it's transmitting something while the car is in use I guess this would also cause battery usage.
To change the battery in a Ford F250 key fob, please follow the steps below: Locate the battery compartment on the back of the key fob. It will have a small indentation or button that needs to be pushed to release the cover. Press the button or use a small tool like a screwdriver to push the indentation and release the battery cover. zMSxY.
