Opening the Key Fob and Replacing the Battery
If you need to replace the battery or access the internal components of your key fob, follow these instructions for opening it safely. Look for a notch or indentation on the side of the key fob, usually near the keyring attachment. This is where you will insert a small screwdriver to pry the fob open.
Tip: Be careful when prying the key fob open to avoid damaging the plastic casing or any delicate internal components.
Once you have located the indentation, gently insert the screwdriver and apply light pressure to release the clips holding the key fob together. Work your way around the edges, ensuring all the clips have been disengaged. Once the clips have been released, the two halves of the key fob should separate easily.

Once the new battery is securely in place, press the two halves of the key fob back together until you hear a click, indicating that the clips have re-engaged.
