A fob with a sliding key has a small button on the top. Hold the button down while pulling on the key to remove it. For a fob with a springing key, press the spring button on the fob or pull the key forward to get it out of the way.
Set the screw aside in a safe spot, such as inside a resealable bag or small cup, to avoid losing it.
Prying a stuck cover is easier if you use the screwdriver on all of the fob’s sides. Work the blade into the seam in a few different spots to separate the halves.
Some fobs have clips over the battery. Lift the clips with the screwdriver to free the battery. Move slowly, lifting the clips as gently as possible to avoid breaking them.
Fobs generally use small, coin-shaped batteries like CR2025 or CR2032. You can usually find them at general stores, home improvement stores, and some auto part stores. To find the specific type of battery yours uses, consult the owner’s manual of inspect the fob and battery for a label.
All key fob should work without having to reprogram it after replacing the battery. A dealer or an auto locksmith can replace the fob. You may also be able to buy a new fob and program it yourself.
