The security door of my house. At night, when I sleep, I lock the security door with the door, and t

The door doesn't always open by itself, someone always opens it. There's a reason for it! Beware of everything, change the lock if you can. Why don't you install a monitor to find out why?

The lock is the heart of the anti-theft door, as long as the lock turns the door opens, the state stipulates that the technical unlocking in not less than one minute to open the door lock, is also considered a qualified product. Change the door.,Give you a brand goods.,But it's inconvenient for me to say here.,I'm worried about the moderator blocking my post.,You can contact me on the site.。

It is impossible to open from the outside, it is to open from the inside.

You let your wife lock it inside, and you won't know if you open it outside! If you can't open it, then I suggest you change to a better lock cylinder, now the thieves, all the masters have, the lock master can open the ordinary anti-theft door in less than ten minutes, that is to say, the anti-theft door you think is not much different from no door in their eyes.

Go and install a sensor yourself, and if something passes, it will sense an automatic alarm.

Press the monitor and see what's going on.

Well、、、 it's really weird.

You have to ask a special master to take a look at this, otherwise it will be real next time. I won't say anything unlucky, spend a little money, and keep safe.

Maybe there is a problem with the security door you are using, find a master to repair it.

There is no lock that cannot be opened, beware.
