    I didn't see your fingerprint lock.

    Fingerprint locks are just convenient, and when it comes to anti-theft, it still depends on the mechanical performance.

    Excuse me: Can your anti-theft door lock be reversed? It is called anti-lock on the outside, and it cannot be opened without a password fingerprint on the inside.

    If you don't have this function, you can somehow stretch an iron rod into the door and press it open. That's not even as good as a normal lock.

    Also look at the fingerprint recognition rate: a fingerprint collection head, a better one is 600 yuan.

    This 600 is the cost of parts! If the quality is not good, the fingers are too dry, the fingers are too damp, and the cosmetics are not good.

    Fingerprint locks have a backup unlocking method. It's a spare key to unlock.

    The need for a spare key also has a high level of anti-theft performance. I've seen the same cylinder used for spare keys and outdoor trash cans in the community.

Summary. Under normal circumstances, if you lock the security door with a key from the house, the key will not be removed and it will not be opened from the outside.
