How do you change a Toyota key fob battery?

Is there a way to change my Toyota key fob battery, or do I have to take it to a dealership? My key hasn’t been working as well lately, and I think the battery is dying.

Definitely! You can change your Toyota key fob battery quickly and easily by following these steps:
  • Press the small metal button located at the top of your key fob and remove the metal key.
  • When you remove the key, there will be a small hole left behind. Use a flathead screwdriver or another small, flat object to fit into the hole and pop the key fob open.
  • Carefully, remove the green circuit board from the key.
  • Make sure that the battery in your key fob and your replacement battery are the same type. Most Toyota key fobs will require a ​​CR 2032 3V battery, but it’s a good idea to compare the two.
  • Remove the old battery and replace it with the new one. Make sure that your new battery faces the same way as the old one, with the negative and positive terminals in the same positions.
  • Replace the circuit board carefully in its original position.
  • Finally, click the two halves back together and replace the metal key.
  • Remember to test your key fob to make sure that it’s still functioning as it should.
