The anti-theft door can not be opened from the inside, it is likely to be the problem of the lock cylinder, the lock cylinder of the anti-theft door will appear after a long time, it is recommended to change the lock cylinder, so as not to lock the door next time can not open the tragedy, now there are sales on the market that kind of super B-level lock cylinder, anti-theft performance is very good. If you really want to change, I recommend the super B-grade lock cylinder of Golden Point Atom, the service and after-sales are good, and the one-year warranty is provided. Two days ago, I also had a problem with the door of my house, the lock could be opened, and it couldn't be opened, and it was fine after changing the lock cylinder.
