Step-by-Step Toyota Corolla Key Fob Battery Replacement
Changing the battery in your 2017 Toyota Corolla key fob is easier than you might think. Follow these steps to get your key fob powered up again:
-
Remove the Mechanical Key: Locate the small button on your key fob. This button is usually a metallic silver color and situated near the key ring. Press and hold this button to release the mechanical key from the fob. Slide the key out completely.
-
Open the Key Fob Casing: Once the mechanical key is removed, you’ll see a slot where the key was housed. Insert a small flathead screwdriver or a thin pry tool into this slot. Gently twist the screwdriver to separate the two halves of the key fob. The casing should pop open without much force.
-
Access and Remove the Old Battery: Carefully open the key fob to expose the internal components. You’ll see a small green circuit board and the round, silver CR2032 battery. Note the orientation of the battery (usually positive side up). Gently pry out the old battery. You may be able to use your fingertip or the small screwdriver again, being careful not to damage the circuit board.
-
Insert the New CR2032 Battery: Take your new CR2032 3V battery and insert it into the battery compartment. Ensure the positive (+) side of the battery is facing upwards, matching the orientation of the battery you just removed.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and properly aligned. You should hear a click or feel them snap into place.
-
Replace the Mechanical Key: Slide the mechanical key back into its slot in the key fob until it clicks securely into place.
Now your 2017 Toyota Corolla key fob should be powered by a fresh battery and ready to use. Test the buttons to ensure they are working correctly.
