I have a shed that many people need to get to it daily, so instead of using the physical key, I bought a Bluetooth (BT), Fingerprint, Key Code and also physical key smart lock from Aliexpress. It cost $50 and it work wonder.
This one uses 4xAAA batteries and 5V microUSB input source in case the batteries power gets low. To replace the batteries, we don’t need to remove the lock, just the face plate with a small cross screw driver. The batteries actually lasted almost 2 years.
