Use a flathead screwdriver or a coin to gently pull the two halves apart. Once you've opened the fob, take out the old battery and then insert an alternative one in its place. Snap the two halves of the fob after you've inserted the new battery. Then test it. If you're still unable to get the key fob to unlock your car or start the engine, try holding it closer to the ignition switch. The key fob's radio transmitter can send a signal to the vehicle's receiver from some distance. However, it will only work with a wireless remote powered by batteries that is close to the ignition.

It may seem impossible that your key fob would require a new battery, however, it's better to be prepared rather than have it happen at the worst time.
