Car Keyfob Batteries

A car key fob is a small electronic device used to remotely control various functions of a vehicle, such as unlocking doors, starting the engine, or activating the car's alarm. It often works via radio frequency (RF) or infrared signals.

To change the battery:

Open the key fob: Most fobs have a small screw or can be pried open with a flat tool.

Remove the old battery: Carefully take out the old battery and note the orientation of the positive and negative sides.

Insert the new battery: Insert the new battery, making sure the positive side is in the correct direction.

Close the fob: Snap the key fob back together or screw it closed.
