Anonymous users2024-01-24First of all, there are three kinds of keys in your set, one is the A key (decoration key or temporary key), the second is the B key (the master key), and the third is the C key (functional key).
Let me tell you about the relationship between these three keys.
The B and C keys are sealed, and the A key is not sealed. After the installation or decoration of the A key, due to the decoration workers or other people have used the key, in order to prevent others from stealing your key outside with ulterior motives, the manufacturer designed the C key. At this time, after you use the C key to insert the lock cylinder and rotate 360 degrees to pull it out, the A key will be invalid and can no longer open the door, that is, the function of opening the door with the B key will be activated.
In this case, the B key and the C key can be used at the same time.
The activation of the B key must be inserted into the lock cylinder with the C key and rotated 360 degrees before it can be used.

ABC key, 1 temporary key A for the contractor, 1 B key for destroying the temporary key function, 5 C key for yourself. Of course, most of the security doors are only divided into AB keys, A keys for the contractor, and B keys that become invalid after using the A key. The principle is that the protrusion of the second key destroys the steel ball inside the door lock that the A key opens normally, so that the shape of the internal lock hole changes. >>>More
