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.
Here’s how to replace the battery in your Toyota Camry remote:
  1. 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.
  2. 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.
  3. Remove the circuit board to access the battery. Make sure to use caution so you don’t damage anything.
  4. Replace the dead battery. Most Toyota fobs use a CR2032 battery, which can be found online and at most big-box retailers.
  5. 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!
