After entering the hotel room, close the door, then lock it, and finally wear an anti-theft chain. Generally speaking, after the lock is locked, you can't open the door from the outside even if you have a room card. After wearing the anti-theft chain, even if you open the door, you can only open a crack and you can't enter the room. It is the safest method.

The chain buckle is installed on the back of the door, not far from the door edge. One end of the sliding chain is fixed on the door frame, and the other end is movable and can be inserted into the chain buckle behind the door for locking.

When hanging the anti-theft chain, the door can only be opened about 5~8 cm at most, so that people can't get through it and their hands can't reach the chain buckle behind the door, ensuring that the host will not be suddenly attacked by the other party when he opens the door to confirm the identity of the visitor. Because the sliding chain is easy to be cut by tools such as metal cutting pliers, the security door chain is rarely used as a door lock alone, but only as an auxiliary tool for theft prevention.
