Use the USB-C port to enter your access code.
Wyze Lock Bolt's low battery indicator will flash red when the batteries are low. If you forget to replace the batteries in time, there is a USB-C port on the bottom of Wyze Lock Bolt that you can connect to a power bank. You can then enter your access to get inside--and replace the batteries ASAP.
This is only a temporary solution and should not be used continuously (connecting the lock to a power bank for longer than a few moments).
