It certainly is frustrating when your key fob stops working, so it’s a good move to replace the battery before then. To replace a Toyota Tacoma key fob battery:
  • Locate and push the internal key release button to remove the key. The button may say “push” on it
  • Near the space that the key was just removed from, you’ll find a small slot. Gently wedge a small flathead screwdriver into the slot and carefully twist the tool so the fob case splits apart
  • Slide the same tool behind the battery to remove it. Be careful not to damage any circuitry behind the battery with the tool
  • Insert the new battery with the positive side facing up
  • Align the two halves of the key fob case and snap them back together.
  • Reinsert the internal key
Simple, right? Your Toyota Tacoma’s key fob should be good to go now! And since you’ve just mastered this car maintenance task, you may feel like tackling another.
