Where can I find my device's battery life? 

To determine your device's remaining battery percentage, open the Latch 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 long can I expect the batteries in my Latch device to last?

• The Latch M's batteries should last 12 months under normal usage with 6 x AA Duracell non-rechargeable batteries.
• The Latch C2’s batteries should last 24 months under normal usage with 6 x AA Duracell non-rechargeable batteries.  
• The Latch C1’s batteries should last roughly 9 months under normal usage with 6 x AA Duracell non-rechargeable batteries.  
• The e-Genius Powered by Latch's batteries should last 18 months under normal usage with 6 x AA Duracell non-rechargeable batteries.  

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 Latch App (instead of the Latch Manager App) immediately after changing the batteries. Failing to update the device with the Latch App after battery replacement can result in unreliable functionality or a disruption in guest access.

Latch M Devices:

1. Remove the Latch M's inner trim by removing the two screws on the top and bottom with a Phillips head screwdriver.
2. 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).
3. Update the device using the Latch App (instead of the Latch Manager App).

Latch C and C2

1. Remove the Latch C’s inner trim by removing the two screws on the top and bottom with a Phillips head screwdriver.
2. 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).
3. Update the device using the Latch App (instead of the Latch Manager App).

1. Swipe up to "My doors" or "My Spaces."
   
   
   
   
2. In your Door List, tap the Door you want to update.
   
   
   
   
3. Below the Door name, select "Update" in blue.
   
   
   
   
4. Then, tap the blue "Update" button. Note: You must be close to the device in order to update the Door.
   
   
   
   
5. Once your Door is updated, a green check mark will appear, along with the date and time of the last update.
   
   
   

If the numbers on the lens blink after typing in your doorcode or attempting to use a Latch Keycard, it's possible the doorcode was incorrectly entered or, in both cases, your access may not be synced to the Latch device. We recommend the following:

1. Verify in your Latch App that you have current access to the door you're attempting to unlock.
2. If you do have current access, perform a manual update using the Latch App.
3. Attempt a Latch App unlock by tapping the blue 'Unlock' button.
4. Attempt an unlock using your doorcode and/or Latch Keycard again. Ensure you're tapping the device lens to wake the device before typing in your doorcode or presenting your Latch Keycard and that you're following the doorcode recommendations in this article. 

If these steps do not resolve the issue, we recommend contacting your property management team for assistance. Please include the specifics around the issue you are facing (any error messages or device behavior being seen, etc) so your property management team can troubleshoot the issue further.

If you notice your Latch C device deadbolt is repeatedly extending and retracting, it's possible the device detects a jam.

What happens during a jam?

When the Latch C detects a jam (an inability to sufficiently extend the deadbolt), it performs an anti-jamming routine where it retracts and extends the deadbolt three additional times to give the user an opportunity to take corrective action. After the anti-jamming routine, the Latch C either indicates that it was successfully locked with a locking animation on the Lens, or that the locking attempt was unsuccessful with a double-blink animation on the Lens. If you see that locking was successful, please still test your door to ensure that the door is secure. If the locking was unsuccessful, simply unlock to retract the deadbolt and try locking again.

Ensure you have closed the door the whole way.

On some doors, it will be necessary for you to pull or push on the door while locking to ensure that the deadbolt is aligned with the door frame. This can be for a number of reasons but may be because there is weather-stripping material installed to create a good seal between your door and doorframe to better insulate your home.

Check your door alignment.

It's important that the Latch C locks and unlocks smoothly. The resistance felt when locking and unlocking with the thumb turn is the same resistance the motor encounters. Longterm, this will reduce your Latch C’s battery life and can cause additional wear and tear. If you feel that there is unusual resistance, contact your property management for guidance.
