Dispose of the Old Battery

Properly dispose of your old battery. Batteries should not be thrown in regular trash due to environmental concerns.

Insert the New Battery

Take your new CR2032 battery. Ensure the positive side with the plus sign is facing up. Slide it under the metal piece in the battery slot.

Reassemble the Key Fob

Drop the circuit board back into the front section of the device, with the battery facing up. Click the back section of plastic onto the device.
