- Reassemble the Key Fob: Snap the two halves of the key fob back together until they click securely into place.

What if My Key Fob Still Doesn’t Work?
If your key fob still isn’t functioning correctly after replacing the battery, there may be other issues, such as a faulty key fob or a problem with your car’s receiver.
