To power cycle Wyze Lock Bolt:
Take off the cover, then remove one battery and put it back in. A beep will sound to indicate that it's powered on again.
Warning: If you press the pairing button and take out the battery during the pairing period, Wyze Lock Bolt will delete everything stored in the device (all users and settings). Don't try pairing and power cycling at the same time. Wait for re-pairing to finish first.
