How can I unlock the ULTRALOQ Smart Locks if the battery runs out?

There will be a low battery alert on the lock and App when the battery level is low. The Tri-color LED Indicator will flash RED 3 times, along with three beeps when the lock is activated. Please replace the batteries.

Solution 1. Use the backup key to unlock.

Solution 2. Connect a 5V power bank with the Micro-USB Backup Power Interface to activate the lock temporarily, only for ULTRALOQ U-Bolt Pro, U-Bolt Pro WiFi, U-Bolt Pro Z-Wave, Lever, and UL300.
