Using a bank card or x-ray

This is an approved method, although it works less well with modern doors. It only works if the entry has been slammed. Slammed or locked, the door will remain closed anyway, and you will stay on the threshold.

Since the card you are going to use may be damaged a bit by the operation, choose one that is less important to you. If it is a little flexible, it will be even more useful.

The card should be inserted, taken lengthwise, between the door and its jamb.

The card should be inserted a little above where the door jamb and the lock mechanism come into contact.

Don’t forget the screwdriver

This straightforward method will not allow you to open all locked doors. It can be instrumental if the entry includes an opening button located in the middle. Choose a thin screwdriver, which slides easily into the lock. Once correctly entered into the safety, it will be able to turn inside.

Use percussion keys

Still other keys

They no longer look like standard keys. These are L-shaped metal rods, called hex keys; These are generally used to operate screws or bolt heads. Not all locks can be opened using these keys. Only those with a circular hole in their center can be unlocked using a hexagonal key.
