Review on 🔒 Smart Fingerprint Door Lock - Biometric Keyless Entry Door Knob for Homes, Apartments, Office, AirBnB, Hotels (Silver) by Justin Metz

After restarting the device and switching between locked and unlocked, it worked again. wanted to exchange the unit if the reboot doesn't work, my consolation is if there are problems with the return they are happy to exchange it even though the 3rd June is Revain's return deadline. If I had never had this problem, I would have gotten 5 stars, currently 4 are more than 2. Preliminary remark with 2 stars: I was very satisfied with the easy start in the first few weeks. However, perhaps because it was getting close to 90 degrees for the first time, it seemed to recognize my thumbprint, a blue light, but didn't open. I started charging the battery hoping that was the problem. But today when it does the same thing I switched to open mode and the door still doesn't open. Slightly maneuvering the key in can cause it to get stuck for a short time, but is no longer functional after a few attempts. Tomorrow I will try to find recommendations from the manufacturer.
