How To Change The Battery In A GMC Key Fob  
 

The battery in your GMC key fob should last for three to four years, but it will need to be replaced eventually. Fortunately, that is a fairly simple matter. The back cover of your key fob can be removed, and the battery can be replaced in just a few minutes.

First, you need to make sure that you have a CR2032 battery. These 3-volt batteries can be purchased from just about any hardware or department store for a few dollars. You can even buy them in packs of three or four if you want to have a few extras on hand.

When you have the proper battery, carefully pry the back cover of your key fob off with a flathead screwdriver, remove the dead battery from where it's housed, and replace it with the new battery. The positive side should be facing you, but look closely at how your old battery was in place to make sure. After that, line up the two halves of the key fob and push them back together until you hear a click.

In most cases, this should be all you need to get your key fob working again. If it doesn't work, there may be other issues that you need to fix either with your vehicle or your key fob. Our dealership will be able to help you with that, so contact us if you have any questions or if your key fob stops working for any reason other than a dead battery.
