Replace GM Keyless Remote Battery
The compact batteries that are used in GM keyless entry remotes require periodic replacement. Taking in a keyless remote for battery replacement to a car dealer can set you back $20-$50. You would not take your TV remote to an electronics store to have the batteries replaced, so use the same logic for your car’s keyless remote. Do it yourself and save some money.
Warning: Take care when opening the remote’s case and removing the battery to avoid damaging the delicate connection of the battery holder to the circuit board.
- Small screwdriver or flat thin tool
- Replacement battery (typically a CV 2032)
- Voltmeter or multimeter (optional)
Keyless Remote Battery Replacement
Step 1: Starting at the bottom opposite the key ring connection, use a small screwdriver or flat tool to pry open the black case of the keyless entry remote. Take care not to crack the case, damage the circuit board inside or hurt your hands in the process.
Step 2: Inspect the position and orientation of each part inside the remote’s case. There should be a circuit board with attached battery and a rubber button grommet in addition to the 2 halves of the black case.
Step 3: Carefully slide the old battery out of the battery holder on top of the circuit board.
Step 4: Optionally you can check that the battery was dead by using a voltmeter or digital multimeter. Most GM keyless entry remotes use a CR 2032 battery which provides 3 volts DC.
Step 5: Place the new battery into the battery holder with the imprinted marking side up, just like the old battery was oriented before removal.
Step 6: Position the rubber button grommet and circuit board together and place properly in one half of the remote’s black case. Line up the second half of the keyless remote case and squeeze together. If the parts do not fairly squeeze back together, stop applying pressure since something is lined up incorrectly. Realign the parts and try again.
Step 7: Take the keyless remote with fresh batteries out to your GM vehicle and give it a try. Hopefully everything works and you can enjoy your savings.
