Where can I find my device's battery life?
To determine your device's remaining battery percentage, open the Door App, and select the door name. We recommend performing a Door Update first (tap 'Update' and then 'Update' again) to ensure you are seeing the most up-to-date battery reading. Then, go back to the device page and select 'Device Details,' where you can see your device's battery reading.

How do I change the batteries on my Latch device?
If you don't manage your own Latch device, please request that your property manager change the batteries of your device to avoid any damage. If you do manage your own Latch device, below are the steps to change the batteries for your device. For all Latch devices, you'll also want to follow this guidance for battery changes:
- Replace ALL 6 AA batteries with new batteries of the same brand. Mixing and matching new and old batteries can cause battery failure and reduced battery life.
- Perform a door update using the Door App immediately after changing the batteries. Failing to update the device with the Door App after battery replacement can result in unreliable functionality or a disruption in guest access.
Latch M Devices:
- Remove the Latch M's inner trim by removing the two screws on the top and bottom with a Phillips head screwdriver.
- Replace the 6 AA batteries with AA non-rechargeable alkaline batteries, noting the polarity on the battery tray (for step-by-step instructions, please refer to the installation guide for your device).
- Update the device using the Door App.
Latch C and C2
- Remove the Latch C’s inner trim by removing the two screws on the top and bottom with a Phillips head screwdriver.
- Replace the 6 AA batteries with AA non-rechargeable alkaline batteries, noting the polarity on the battery tray. Also, note the tabs on the outer sides of the battery compartment and the polarity. You will need to slide the battery into place under these tabs before placing the second battery. (For step-by-step instructions, please refer to the installation guide for your device).
- Update the device using the Door App.
