How to replace the battery in a Ford 3-button key

Model: (Various brands) Various
Part: Key

Video tutorial

For this operation, you will need a small flat-head screwdriver and a new CR2032 battery, which can be found at hardware stores, supermarkets, and online. Start by extracting the key blade as if you were opening the car: insert the screwdriver into the slot at the base of the blade, on the inside of the remote.

Pry apart the two plastic shells, which open like a clam. Remove the old battery and insert the new one with the positive terminal facing upwards.

Reconnect the two shells, pressing until they click back together, and done! The key is operational again.
