Your hubs is probably right! To replace the battery in a 2017
Toyota Camry
key fob, follow these steps:
  • Purchase a new CR2032 battery.
  • Push on the side of the key fob (where it says push) to remove the metal key.
  • Using a flathead screwdriver, pry apart the halves of the key fob. Do so cautiously to prevent the contents from falling out.
  • Without touching the battery terminals, remove the old battery. Make sure to note where the positive and negative terminals are located inside the key fob.
  • Install your new battery in the same position as the old battery.
  • Snap the two halves back together and slide your metal key back into place.
  • Make sure to test your key fob to see if it’s functioning properly!
