If your Toyota Camry key fob isn’t working as well as it used to, there’s a good chance the battery is dying. A dead key fob battery can be a major inconvenience, leaving you unable to lock, unlock, or start your car remotely. Fortunately, replacing the battery in your Toyota Camry key fob is a quick and easy process that you can do yourself. This comprehensive guide will walk you through everything you need to know about Toyota Camry key fob batteries, from identifying the right replacement to installing it yourself and troubleshooting common issues.
Understanding Your Toyota Camry Key Fob Battery
Your Toyota Camry key fob is a small, but powerful device that uses a battery to send a signal to your car’s system. Over time, this battery will naturally drain and need to be replaced. Most Toyota Camry key fobs use a standard CR2032 battery, which is a common type of lithium coin battery.

- Intermittent Function: The key fob works sometimes but not others, or only works at certain angles.
- No Response: The key fob doesn’t respond at all when you press the buttons.
- Dashboard Warning Light: Some Toyota Camry models may display a warning light on the dashboard when the key fob battery is low.
Choosing the Right Battery for Your Key Fob
While most Toyota Camry key fobs use a CR2032 battery, it’s always best to double-check your owner’s manual or look for the battery type inscription on the existing battery itself. Purchasing the correct battery will ensure compatibility and optimal performance.

Replacing the battery in your Toyota Camry key fob is a straightforward process:

Troubleshooting Key Fob Issues
If replacing the battery doesn’t resolve your key fob issues, there might be other underlying problems:
- Key Fob Programming: In some cases, you may need to reprogram your key fob to the car after replacing the battery. Consult your owner’s manual for instructions on how to do this.
