- Flathead screwdriver
- CR2032 battery
Remove the Internal Key
First, locate the small switch at the bottom of your key fob. Hold down this switch and pull out the internal key. Set the key aside for now. This will expose the keyhole and a smaller hole next to it, which we will use to open the key fob.
Open the Key Fob
Insert your flathead screwdriver into the smaller hole adjacent to the keyhole. Hold the key fob loosely in your hand and twist the screwdriver. You should feel the key fob crack open. Once it is open, you can pull the two halves apart with your fingers.
Remove the Old Battery
With the key fob open, locate the battery. Use your flathead screwdriver to gently pry the battery out of its compartment. If your screwdriver is too large, you can use a smaller precision screwdriver or even a bent paperclip to remove the battery.
Insert the New Battery
Take your new CR2032 battery and make sure the positive side (marked with a plus sign) is facing up. Slide the battery into the compartment, ensuring it fits snugly under the two small plastic pieces. Press down gently until the battery clicks into place.
Reassemble the Key Fob
With the new battery in place, align the two halves of the key fob. Make sure the side with the silver buttons is facing up. Press the halves together until they click back into place. Finally, insert the internal key back into its slot.
Test the Key Fob
To ensure you have replaced the battery correctly, press a button on the key fob. If the indicator light comes on, you have successfully replaced the battery. Congratulations!
