I forgot my key. How can I open the door quickly?

Insert the rectangular plastic card into the gap between the door and the door frame, and then quickly slide down to the position where the lock tongue is located. This is a very traditional way to open the door, and it only takes a few seconds to open the door smoothly. This method is mostly old-fashioned residential areas, and thieves mainly target wooden doors and old-fashioned security doors.

This unlocking method is suitable for unlocked lock cores, but not for lock cores with safety bolts.

Chewing gum unlocking

The door is locked. How can I open it without a key? Chew the gum soft and put it in the lock hole. Put the gum in the lock hole with a tool.

Some old-fashioned lock cylinder marbles are of poor quality or short length. After being "squeezed out" by chewing gum, you can easily open the lock by inserting the tool into the lock core.

You can also thread a thin wire into the hole of the door lock and try to unscrew the door lock. You can also use pliers and other tools to destroy the iron sheet on the door lock, then use tools to destroy the lock core, and then take down the whole door lock.
