The security door can be unscrewed from the outside without a key, can it be adjusted?

It depends on what kind of security door, some can't be opened, and some can be opened. You'd better take a picture.

Other anti-theft doors are not good, buy Wang Li's anti-theft doors, basically close the door automatically locked, and the technology opens, the lock time is two or three hundred minutes, small * and open, the lock master is too lazy to earn this money. Big brand, don't worry about being unreliable.

The lock with a spring meeting head can be locked as long as the spring meeting is opened, and the door can be locked on the outside, and the lock without a spring meeting head cannot be locked without a key outside, however, most of the security doors are now locks with a spring meeting head, and most of them can be locked outside.

The anti-theft door does not use a key from the outside, and it is a normal door lock to be opened, but you need to be reminded that the person who is required to install the lock is to reinstall it, so that it can not be opened from the outside, but only from the inside.

It may be that the door lock is copied with an external or double-active handle, and it is recommended to replace the door lock. >>>More
