On modern Chevrolet key fobs, the key itself is used as a tool to help you swap out the old battery for a new one.

If you're looking to pick up a new key fob, or repair one, you might wonder how long programming it takes and whether or not you can do it yourself.

Extra key fobs are now available for those fleet customers who ordered them for 2025 Chevy Silverado HD and 2025 GMC Sierra HD trucks, with programming extra.

Batteries fade and die over time, but but changing the cell in your Chevrolet key fob doesn't have to be difficult.
