Screwdriver Attempt

This automotive "how-to" guide was specifically written to assist owners of the 1997 to 2003 GM Pontiac Grand Prix in replacing the coin battery inside the key fob remote control.

Owners of other General Motors brand vehicles from Chevrolet, Buick, GMC, Cadillac, Saturn, Hummer, Oldsmobile and Pontiac with similar keyless entry remote controls may also find this guide to be useful.

After nearly 10 years of service, the key fob remote controls for my 2001 Pontiac Grand Prix are only able to open or lock the car doors from a foot or two away.

To open a GM key fob, you'll need either a flathead screwdriver or a thick coin such as a U.S. Quarter.

The original battery is a Panasonic CR 2032 3V coin cell. A replacement CR2032 can be purchased at Radio Shack, on eBay, or a pharmacy such as CVS.

Key Fob Remote Open
The first step is to remove the remote control from the key ring. I had trouble popping open the key fob using several flathead screwdrivers until I figured out that a U.S. Quarter would work best. Insert the edge of the Quarter into the notch located next to the key ring hole and turn it to pry open the two halves of the remote.

Panasonic CR2032 3V


 
Once the halves of the key fob remote control are separated, you can gently pry out the Panasonic CR2032 3V watch battery with a small flathead screwdriver from the bottom half of the key fob. Replace the old battery with a new one, being sure to place the "+" (top) side of the battery down. Finish the job by lining up the two halves of the key fob and snap them together. Then re-attach the key ring and test to see if the new battery vastly increases the distance at which you can lock or unlock the doors and pop open the trunk.
