Adopt it, haha.

An security door has an area of about 2 (square meters) and a width of about 1 (meter).

If someone in the room can open the door, then you can directly remove it, a total of three screws, two panel screws (at the indoor end), a lock cylinder fixing screw (in the middle and lower part of the lock body baffle on the door side), if you can't take it out, directly use a pipe pliers to break the lock cylinder, take it out, and then replace the lock cylinder. >>>More
