Can the hotel security chain be opened outside?

They can't be opened in a very safe situation. However, if you want to seek psychological comfort, you can move a chair and put it at the door. You can also leave the beer bottles and beverage bottles left outside at the door. Take it back and put it at the door, so that if you accidentally kick it down, they will make a noise. You can also leave your suitcase at the door.

One side of the anti-theft chain is movable and the other side is fixed. Putting the chain head into the lock and placing it along the inside of the card slot can play a double safety role, but it is only an auxiliary role and can be clipped off with metal pliers. But you can't take the chain off from the outside by hand. When the anti-theft chain is hung, the door can only be opened 5 to 8 cm, and people can't get through.

The anti-theft chain can be stuck in the slot, and there is double insurance in the hotel door. The anti-theft chain cannot be opened from the outside after being locked, and one side of the anti-theft chain is movable and the other side is fixed. If you put the chain head in the buckle and walk along the groove, it can play the role of double insurance. If you tear it off from the outside by hand, the anti-theft chain will not come off.
