Anonymous users2024-01-23Haha, this is easy, the reason is that the anti-theft lock inside is half locked when the door is closed, you turn the key in reverse, all the way to the lock of the anti-theft lock, and then turn it back, so that it can be opened normally
1. Because the safety bolt button inside the door is loose, the safety bolt is shaken down by excessive force when closing the door, and the lock cylinder can be rotated with the original key, but the door cannot be opened. >>>More
Before installing the door, you should communicate with the foreman, and leave a few centimeters off the ground for the anti-theft door to open inside, and the consequences should be borne by the decoration company. >>>More
You can ask the lock changer in the store to come and help you see if it can be repaired. If it doesn't work, you can only ask him to help you change the lock cylinder of your security door.
Is there a key? If you try to push the key inside and turn it, you can open it when you have time.
Causes and solutions:
1. Check whether the anti-theft door key is correct, and whether the anti-theft door key and lock are damaged. >>>More
