They are powered by the same two-dollar battery that is used in hearing aids and watches. The batteries are available in drug, hardware and online stores.
If the battery is fine, it's likely that the buttons are dirty or worn down, and can be cleaned using a damp cloth to wipe them down. If the buttons do not work, try another car key fob.

This is an expensive proposition particularly if you're down to one functioning fob. It is always advisable to have at least one spare mechanical key that you can use to open the doors and trunk, even if it won't start the car.
If you attempt to reprogram your fob on your own be prepared for a frustrating journey. You'll be disappointed with the countless online guides that promise success.

Fobs utilize a small radio transmitter on circuit boards to communicate with the car's receiver. By pressing a button, the transmitter sends an RF signal unique to the car's receiver. The receiver recognizes and compares the signal to preprogrammed codes. This allows a driver to start the vehicle from a distance without the need to insert the ignition key in.
If the buttons on your key fob are not responding or working intermittently, they may be damaged by water. You can fix the fob by taking it apart and examine for damaged or non-responsive buttons. If this does not solve the problem, try reprogramming the fob or purchasing an entirely new fob.
