Recognizing a Weak 2021 Silverado Key Fob Battery
How do you know your key fob battery is dying?
Several signs indicate a failing key fob battery. These include decreased remote range, intermittent functionality (where the fob sometimes works and sometimes doesn’t), and the need to be unusually close to the vehicle for the key fob to function. Also, look out for the dashboard displaying a “Key Fob Battery Low” message. This is a clear indicator that a replacement is needed.
What if my key fob stops working entirely?
If your key fob completely stops working, you can often still start your vehicle using the hidden key inside the fob. Consult your owner’s manual for the exact location of this key and how to use it with your specific Silverado model.

Identifying the 2021 Silverado Key Fob Battery Location
Removing the Old Battery
Once open, locate the CR2032 battery. Carefully pry it out using your flat-head screwdriver, taking care not to damage the battery contacts.
Installing the New Battery
Insert the new CR2032 battery, ensuring the positive (+) side faces upwards. Press it firmly into place until it’s secure.
Closing the Key Fob
Align the two halves of the key fob and press them together until you hear a click. Test the functionality of the key fob by locking and unlocking your Silverado.
“Regularly checking your key fob battery can save you from unexpected headaches down the road,” says John Davis, Senior Automotive Technician at CarDiagTech. “It’s a simple preventative measure that can prevent a lot of inconvenience.”
Troubleshooting Tips
What if the new battery doesn’t work?
If your key fob still doesn’t work after replacing the battery, try reprogramming it. Your owner’s manual will provide instructions on how to do this. If reprogramming doesn’t solve the issue, it might be a problem with the key fob itself, and you may need to consult a dealership or qualified technician.
“Sometimes, the issue isn’t the battery itself, but the contacts within the key fob. Make sure these are clean and free from corrosion,” advises Sarah Miller, Electrical Systems Specialist at CARDIAGTECH.
Conclusion
Replacing the 2021 silverado key fob battery is a simple and inexpensive procedure that can prevent frustrating situations. By following this guide, you can maintain the convenience and security of your vehicle. Remember to have a spare CR2032 battery on hand, just in case.
