The unit door is locked and belongs to the scope of property maintenance and maintenance, the property is responsible for repair, if they are not repaired, you ask to see the property service agreement or contract, and minor repairs to public parts are definitely within the scope of service
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.
You can go to Youku to search for a master key that can't be "locked" to see if the lock at home will be opened by thieves. Then go to Taobao to search, the home of the railway home online store to see, I feel that his super B anti-theft lock cylinder is very safe, hehe.
Forehead.. No, you can change the door, if you can do it, you can remove the lock and buy one on the Internet, if you don't have strong hands-on ability, call the unlocker and ask them to change one, so that they can change it is much more expensive than changing it yourself.
