Step-by-Step Battery Replacement

1. Remove the Internal Key

First, locate the small switch at the bottom of the key fob. Hold this switch down and remove the internal key. This will reveal the keyhole and a small slot in the plastic, which will be used in the next step.

2. Open the Key Fob

Insert a regular flathead screwdriver into the slot perpendicular to the keyhole. Hold the device loosely and twist the screwdriver. The key fob should crack open easily. Set aside the top part of the fob and lift out the internal component.

3. Remove the Old Battery

Using a smaller flathead screwdriver or a precision screwdriver, pry up the old battery from the small area underneath it. It should pop out with minimal force. If you don’t have a precision screwdriver, a paper clip can also be used.

4. Insert the New Battery

Take your new CR2032 battery and place it under the two small pieces of plastic in the battery compartment. Push it down until it clicks into place. Ensure the battery is securely seated.

5. Reassemble the Key Fob

Carefully lift the internal component and place it back into the key fob. Snap the top part of the fob back into place. Test the key fob by pressing a button and checking if the light comes on, indicating the battery is working correctly.
