The battery can be checked by opening the case of the key fob with a screwdriver and determining whether it's dirty or requires replacement. The most commonly used batteries in key fobs are 3V button cell batteries that can be bought in almost any retailer.

Broken Battery Terminals

If your fob doesn't work when you attempt to start your car it could be because the battery terminals have failed. To unlock and start your vehicle, the fob needs to be able to communicate with the central system of your vehicle. This communication is carried out via a small transmitter inside the key fob. The transmission signals are sent to the car key's internal circuit (if there is one) and it unlocks the doors and begins the engine. The fob can transmit the signal as far as 50 feet away, but should the battery's terminals are damaged, the transmission may not function.

Modern keys need to be programmed in order to work with a specific vehicle, and certain error codes may cause a problem with the programming on the key fob. This can be corrected by a professional who can program the key again to the car.

The circuit board could be damaged because the key fob had been exposed to excessive heat or other issues. Sometimes, this is because of having work done on your car that accidentally exposed wires, which could cause other issues, such as a damaged horn or a malfunctioning key fob. Make sure you check your key fob, and replace it or repair it if needed. In the absence of a functioning key can be stressful and potentially dangerous.
