What you will need:

  • 1x CR2032 battery

First step—pull the silver switch on the back of the device to release the internal key. Next, look at the bottom of the key fob. Next to the keyhole there is a slot. Insert a flathead screwdriver into the slot and twist, this will separate the two halves of the device.

From here, all you need to do is lift the battery out of its housing with your screwdriver. Be gentle! Take a new CR2032 battery and click it into place positive side down. Finally, click the two halves of the device back together. That’s all it takes. Well done!
