How do I change a Toyota key fob battery?
The key fob for my Toyota Camry is hardly working to unlock my car. I think it’s time to change the battery. What’s the easiest way to replace a remote battery for a Toyota?

I see how that could be frustrating! It’s actually pretty simple to change a Toyota key fob battery, and it will only take a few short minutes.
- Pull the metal spare key out from the fob. Press the small metal button at the top of your fob to release the key and pull it out.
- Open the key fob. Use a flat tool, like a flathead screwdriver, to stick into the slot for the metal key and turn it to pop open the fob.
- Remove the circuit board to access the battery. Make sure to use caution so you don’t damage anything.
- Replace the dead battery. Most Toyota fobs use a CR2032 battery, which can be found online and at most big-box retailers.
- Put it all back together. Replace the circuit board, snap the plastic back together, and reinsert the metal key. Then, test the fob.
Just like that, you have a fresh battery in your Toyota key fob!
