Replacing a General Motors key fob battery

General Motors key fob battery

We recently added a new video replacing a General Motors key fob battery. The fob is used in various Buick, Chevrolet and GMC models and Cadillac uses a mirror version of the same fob.

The fob uses a larger battery than is typically seen, a CR 2450. It will last longer than the more common CR 2032. The embedded mechanical key and the tip of a very small screwdriver will be needed as tools.

The video has been added to our Buick, Cadillac, Chevrolet and GMC, and pages here, here, here, and here respectively. Overall, we now have a seven videos that help drivers of GM models in the event that the battery in the key fob dies. These videos will help you get in and start your vehicle even if it is not responding to the key fob, as well as replacing the battery in the fob.
