Install the New Battery
Take the new battery and position it in the same orientation as the old one. Press it down gently until it clicks into place. Ensure it is seated properly and that the contacts are making good contact with the battery terminals.

Align the two halves of the key fob and press them together until you hear a click. Make sure there are no gaps between the two halves. If needed, use the flathead screwdriver to ensure a snug fit, but be cautious not to apply too much pressure.

After reassembling, test the key fob to ensure it works correctly. Stand near your vehicle and press the lock and unlock buttons. If the key fob is functioning properly, you should hear the locks engage and disengage. If it does not work, double-check the battery orientation and the fit of the key fob.
