    That's because the lock in your house was picked by a thief, and then the lock cylinder inside was damaged, but it was not completely broken. So you can open it with the B key. The A key can't be opened.

    It is recommended that the merchants who sell security doors consult and let them go to the scene to see the situation!

Because there is a transmission mechanism of the lock tongue inside the lock body, when the lock cylinder rotates, the fork in the middle of the lock cylinder will drive the transmission mechanism of the lock tongue, thereby driving the indentation or extension of the lock tongue, the gear is also there, the fork is also there, the function is indeed the same, I don't know if I say this, you understand it.
