Why can t the lock tongue of the anti theft door enter the card slot when the door is closed?

In this case, it should be the dislocation caused by the loosening of the screws that fix the door, and it is recommended to find a door lock master to adjust it.

The deadbolt of the security door cannot enter the card slot when the door is closed, and it is likely that it is because of the security door. Snakes are immobilized and therefore cannot bounce back automatically. As usual, one cannot be retracted into the card slot, and another possibility is that the lock of the security door is artificially damaged.

After being damaged by man-made damage, the spring construction is damaged, resulting in a lock. The deadbolt cannot be made of springs. It cannot be retracted freely, so it cannot be snapped into the card slot.

The diagnosis was that the door was deformed or drooping.

The deadbolt does not lock smoothly into the door frame.

There are two common problems we find when changing locks:

Try for yourself which direction you are off.

1. Generally, the door is sagging, and the phenomenon is that you have to lift the handle to lock the door or open the door, so you use a steel file to file the lock mouth on the door frame as a whole until the door no longer needs to lift the handle.

2. In addition, the vertical direction of the door has been deformed, and the phenomenon can only lock the lock by pulling the door hard, and there will be a sound of collapse when opening the door, so you can file it in the direction of the door with a steel file (file the door in the direction of the house, and vice versa).

The door is deformed, and the deadbolt cannot be aligned with the keyhole of the door frame, so it is enough to correct the keyhole of the door frame.

The reason why the door lock tongue can't enter the card slot is generally because the door is deformed or sagging, and the lock tongue can't be locked into the card slot smoothly.

1. The door is sagging, that is, you need to lift the handle to lock the door or open the door; Then use a steel file to file the lock on the door frame downwards as a whole, until the door is no longer required to lift the handle.

Advertisement 2, the door is deformed vertically, that is, the door can be locked by pulling the door hard, and there will be a sound of collapse when the door is opened; Then you need to file in the direction of the door opening with a steel file (file the inside door in the direction of the house, and vice versa).
