Dead Key Fob Battery on a 2023 Chevy Silverado: How to Get Back In & Start It
A dead key fob battery on a 2023 Chevrolet Silverado can leave you unable to unlock the doors remotely or trigger push-button start like normal. The good news: your Silverado has built-in backup methods to get in and drive, and a fob battery swap is usually quick and inexpensive.
Understanding Your Situation
The coin-cell battery inside the Silverado’s key fob has discharged, reducing or eliminating the fob’s ability to transmit a signal. You may still be able to start the truck using the vehicle’s passive/backup detection method or by using the hidden mechanical key to unlock the door.
🚀 Immediate Steps to Take
- Use the mechanical emergency key inside the fob to unlock the driver’s door (look for the release on the fob, then use the key in the door lock cylinder—often hidden behind a small cover on the handle).
- If the truck has push-button start, start it using the backup method: hold the fob against/near the designated receiver area (commonly the start button area or a specified pocket/slot depending on trim) while pressing the brake and pushing START. If it’s a keyed ignition, insert the key blade (if applicable) or use the backup start procedure in the owner’s manual.
- Replace the key fob battery with the correct coin-cell (commonly a CR2032 on many GM fobs, but verify your exact fob/trim by checking the old battery or the owner’s manual), then test lock/unlock and remote start (if equipped).
⚠️ What to Avoid
✕ Don’t force the fob open with a large screwdriver—use a small plastic pry tool to avoid cracking the case or damaging the seal.
✕ Don’t assume the battery type without checking; install the same type printed on the old battery (CR2032 is common, but not universal).
✕ Don’t keep pressing buttons repeatedly at close range for long periods—if the fob is weak, it can drain the remaining battery faster and may confuse troubleshooting.
⚠️ Common Mistakes to Avoid
- Using wrong battery type
- Damaging case during opening
- Not resetting after replacement
- Buying expensive batteries
Frequently Asked Questions
Can I start my 2023 Silverado if the key fob battery is dead?
Usually, yes. Most trims with push-button start have a backup method that lets the truck read the fob at very close range. Use the emergency key to get in, then hold the fob against/near the designated receiver area (often near the START button or a specified pocket/slot depending on trim) while pressing the brake and pressing START. Check your owner’s manual for the exact location for your truck.
What battery does a 2023 Chevy Silverado key fob use?
Many GM/Silverado fobs use a CR2032 coin-cell, but it can vary by fob style and trim. The safest way is to open the fob and read the battery number on the old battery, or confirm in the owner’s manual or with a Chevrolet parts counter.
Do I need to reprogram the key fob after replacing the battery?
In most cases, no. Replacing the coin-cell battery does not erase programming. If the fob still doesn’t work after a new battery, check battery orientation, contact tabs, and whether the fob was damaged by moisture or impact.
My fob works up close but not from far away—does that mean the battery is dying?
Often, yes. Reduced range is a common early symptom of a weak coin-cell. Replace the battery first. If range is still poor, the issue could be interference, a damaged fob, or (less commonly) a vehicle antenna/receiver problem.
