Fobs utilize small, coin-shaped batteries that can be replaced in a few minutes. They are available at home improvement stores, and even auto parts stores. Make sure you purchase the right type.

The key fob contains a short-range radio transmitter/radio-frequency identification (RFID) chip and antenna, which sends a distinct coded signal to the receiver module in your car. If the signal isn't in order the receiver module will not recognize the key and display an error message that states the key is not detected. This is a problem that can be frustrating, especially when trying to start your car.

Before replacing the battery, it's crucial to ensure it's of the correct type and size. The circuit board on the key fob can be damaged when the battery you replace is too large or has different voltage. You should also clean any corrosive material from the chip inside the fob prior to installing a new battery. The right battery type can ensure that the key fob is sealed and protected from moisture. Once the key fob is replaced, it should work normally. You should be able to use the second key even the car displays a message saying "key not found."
