Published on Jan 10, 2023 by Boulder Service Team

The car keyfob is one of the most important pieces of technology for a car driver. Without it, a driver would be unable to unlock or start their car. As such, it is important to make sure that the keyfob is always in good working order, and this includes regularly changing the keyfob battery. Fortunately, replacing the keyfob battery is not a difficult task, and can be done relatively easily.


The first step in replacing a car keyfob battery is to determine what type of battery is needed. This information can be found in the owner's manual for the car, or on the back of the keyfob itself. Once the type of battery is determined, the next step is to purchase a new battery that is compatible with the keyfob. Batteries of the correct type and size can be found at most electronics stores or in the parts deparment at your local dealership.


Once the new battery has been purchased, the next step is to remove the old battery. This is done by taking a small flathead screwdriver and carefully prying the old battery out of the keyfob. Once the old battery is removed, the new battery can be inserted into the keyfob. Be sure not put the new battery in upside down. This will cause the key fob not to operate correctly. 


The last step in replacing a car keyfob battery is to test the keyfob to make sure that it is working correctly. This can be done by pressing the various buttons on the keyfob, such as the lock and unlock buttons. If the keyfob is working correctly, then the battery replacement process is complete.
