Here are the steps on how to replace the battery in your key fob:
1. Locate the key fob battery compartment. It is usually on the back of the fob.
2. Open the battery compartment. Some key fobs have a small slider that you need to move, while others have a small screw that you need to remove.
3. Remove the old battery. Be careful not to touch the positive and negative terminals of the battery with your fingers.
4. Insert the new battery. Make sure that the positive and negative terminals of the battery are facing the correct way.
5. Close the battery compartment.
