Secondly, if you are the only one who has the key, you should call the security door manufacturer for help. Because the manufacturer's technicians are more professional, and the parts of each brand product may also be unique. Therefore, please ask the manufacturer's technicians to get the necessary repair and replacement services.
It is not recommended that the owner find a lock picking company to open the lock without permission. First of all, some unlocking companies only need to open the lock and repair it, and finally the owner has to find the manufacturer to repair, so that the warranty problem is difficult to solve. Even if the lockpicker can repair the door lock, because the original parts are not produced by the original factory, the accuracy of the assembly may not meet the requirements, so it is likely to bury a safety hazard for the use of the door lock.
So this is a very good way, if you can't open it, call the sales location of the security door.

There is also a situation when the door handle is loose, resulting in the loosening of the connecting rod between the front lock and the rear lock, we can open the door from a new fixation, if these two methods do not work, we can only remove the door lock and replace it with a new door lock.
Unload, find or find someone to open the lock, add a little less oil to the lock, a little even,
Use a hard plastic sheet to insert it from the crack of the lock door, if the door crack is not too tight, it is okay, similar to an ID card, it is best not to use an ID card.
Don't worry about the broken door at home, teach you how to remove the door lock, and you can change it at home.
Hello answer, at present, according to your question, I have summarized three points 1, first of all, you can find a tool, such as a screwdriver, pry the base under the door handle of the room with a screwdriver, you can see the structure after prying, after screwing down, twist the doorknob counterclockwise, you can generally unscrew it, and then get the deadbolt back. >>>More
First, unscrew the middle lock cylinder screw, take out the lock cylinder, and remove the inner screws by removing the inner screws from both handles.
