Key Fob Not Working: Battery Replacement
Common Reasons Your Key Fob is Malfunctioning
Several factors can contribute to a key fob’s failure. Identifying the root cause is the first step towards finding a solution.
Dead Battery
The most frequent reason a key fob stops working is a dead battery. Key fobs rely on small batteries to power their wireless signals. Over time, these batteries deplete, eventually rendering the key fob useless. Replacing the battery is usually a simple and inexpensive fix. You can often find instructions in your car’s owner’s manual or online. For example, if you’re struggling with a 2018 Chevy Malibu, you can learn how to replace key fob battery 2018 chevy malibu.
Key Fob Programming Issues
Sometimes, the key fob might lose its programming, preventing it from communicating with your car. This can happen after a battery change, or due to electronic interference. Reprogramming the key fob might require a visit to a dealership or a qualified automotive locksmith.

Physical Damage
A dropped or damaged key fob can suffer internal component damage, affecting its functionality. Cracks in the casing, broken buttons, or water damage can all lead to a malfunctioning key fob.
Signal Interference
Electronic devices, radio towers, or even other key fobs in close proximity can interfere with the signal between your key fob and your car, preventing it from working correctly. This is less common, but it can still happen.
Troubleshooting Your Key Fob
- Check the Battery: If your key fob isn’t working, the first thing you should do is check the battery. Replace it with a fresh one and see if that solves the problem.
- Try the Spare Key: If you have a spare key fob, test it to see if it works. If the spare key functions properly, the issue lies with the original key fob, not the car’s receiver.
- Check for Physical Damage: Inspect your key fob for any visible signs of damage. If it’s cracked, broken, or has water damage, it might need to be repaired or replaced.
- Move Closer to Your Car: If you suspect signal interference, try moving closer to your vehicle and trying the key fob again.
