Anonymous users2024-01-24Dear, if the anti-theft door lock is not broken, there is no need to replace it all, you only need to replace the lock cylinder, it is very convenient to disassemble and assemble it yourself. Then go online and look for one. The disassembly and assembly method is as follows: the first four are disassembled, and the last four are installed, is it very simple.
Then measure the size of the lock cylinder according to the figure below and you can find it on the Internet. As shown in the figure below, you need to measure the distance from the two sides to the center of the middle screw hole. It's very simple.
Most of the places where security doors are sold have lock cylinders, and of course, there are also places to repair locks.
Regular lock picking companies and hardware lock shops, such as (Li Wen lock city, actually home) and so on.
It is recommended that you buy it on Taobao, which is much cheaper than in a physical store. Just pay attention to the specifications of your existing lock when buying, otherwise you can't use it. I've bought good ones online.
It's advertising again, don't go, it's all liars.
Hello, it's best not to replace the anti-theft lock yourself. Because first of all, if you buy the lock yourself, there is no formal channel, the quality of the lock is not guaranteed, and secondly, the internal structure of the anti-theft lock is complex, if there is no installation right, it may lead to the door lock not being opened, which is too dangerous. Therefore, it is recommended that you find a professional for repair and replacement, such as contacting the anti-theft door manufacturer or finding a regular lock company (you can call 110 for consultation). >>>More
