You’ll need to replace the rubber ring underneath the battery, too.

Once you have a new battery, you’ll need to replace the cover on the key case. Place the new battery with the positive side facing up. The key cover will need to be attached to the key case until you hear a click.

Changing a key fob battery can save a lot of money. If you are not sure about handling the key fob circuit, do not touch it with your bare hands. It can be dangerous.

The most common key fob problem is that the battery is not working. A faulty battery can stop the immobilizer system from working. A weak battery can also prevent the keyless entry system from receiving a signal from the key. It can also prevent the engine from starting.

The battery may be the culprit, but other problems can also contribute to the key’s malfunction. If your key is unable to start your Mazda CX-5, you may want to consider replacing the battery. A key fob battery is marked with the voltage it holds.

Another common key fob problem is that the buttons are faulty. You may need to press the button several times before the vehicle accepts the signal. You should also check to see if the locking mechanism of the car is working properly.
