How to prevent cat's eye from unlocking
Some brands of fingerprint lock manufacturers have specially designed anti-cat-eye unlocking buttons for this phenomenon. After pressing the button, the door handle can be fixed directly, but the handle cannot be pressed inside the door, and the door can still be unlocked in the correct unlocking way without affecting the use.
In addition to this specific anti-cat-eye unlocking design, there are other ways to prevent thieves from unlocking through cat's eyes:
1. Lock the fingerprint lock mechanically, and lock the fingerprint lock when going out. Even if someone presses the handle through the cat's eye, the locked bolt will pop out of the back door and cannot be opened.
