Behind it is the mechanism that is activated with the help of the previous key, this pushes the inner lock body upwards and releases another keyhole. Then the inner lock body can be unlocked with the help of a key. After this the mechanism on the key hole on the shackle can be unlocked with another key. Finally, you have to unlock the key hole on the wide with the help of the last key. After this, the trick lock is open.
