How long does the battery last from one charge? How to unlock Smart Lock C210 when the battery dies?

Roughly 4 months depending on usage(10 times unlock through keypad or app). You'll get a notification when the battery is low. If the battery dies, you can power it up via the port on the bottom of the exterior lock. (Includes 2 physical keys.)

What temperatures can the Smart Lock C210 handle?

The C210 Smart Lock(exterior part) can handle temperatures within the range of -22℉ to 158℉ (-30℃ to 70℃). We do not recommend using the Wi-Fi Smart Lock outside of these conditions.

It works with eufy doorbell. However, It's not compatible with these services yet.Neither does it work with eufy HomeBase or any wifi bridge.

Very Difficult To Obtain Spare Keys.

If you find you need any spare keys additional to the 2 provided, don't expect to just go down to your local key cutting kiosk or even locksmith and get them made.The key profile is unique to Eufy.
