Sensor Battery Replacement?

I read that the sensor batteries are expected to last 12 months. However, I do not see any instructions for battery replacement. Are they replaceable? If not, are we expected to throw them away? Thank you.

Yes, they are replaceable coin style batteries. The Motion Sensor uses CR2450 and the Contact Sensor uses CR1632. They are replaced by putting a small flat screwdriver or perhaps a dime in the slot on the side of the sensor case and popping it open.


We need a battery replacement section with a graphic in the Support files.
This is another thing that may seem obvious to some, but baffles others.


Thank you both for your replies. That covers the issue quite well.

I’ve already asked them directly to add that. :slight_smile:

One of my door sensors already has a dead battery. :frowning: It is on our front door.

Thanks! I lost one battery when my garage door scraped the large part of the contact sensor off. Happened once before, and replacing the battery and remounting fixed it up. This time, I just can’t find the battery. :slight_smile: Thanks for giving the sizes. I’ll get some ordered.

You can see someone opening up a Wyze motion sensor here:

And, of course, once you’ve opened up the sensor, it’s a simple matter to swap out the battery.

I’ve confirmed that the Wyze contact sensor opens up in the same way.
