What brand is good for the anti theft door, and there is a problem of changing the lock?

Landlord, it is recommended that you go to your anti-theft door manufacturer store to buy a lock cylinder of the same model, (must be the same model, otherwise it can not be installed), and then go to find a carpenter master to help you change, or call the property master to help you change, you can keep the key can be pulled, it is more troublesome to change it yourself, you can also try it yourself!

It seems that you have made a serious mistake like most people, changing the lock is a big thing, not just a lock seller can be, the store that can change the lock must be filed with the public security bureau, and obtain a business license, not to say that any store can be changed. My family has just changed the locks, and I found a license, so that there is security. Hurry up and check if the store that will help you change is qualified, and if you're unlucky and he doesn't, then hurry up and change it again.

I have an anti-theft door in my own home, because there was a theft incident in the community some time ago, I didn't know what brand was good, and the neighbors recommended these brands: Qunsheng, Ruiyi, Wanjia, Xinduo, Longtai - Yihe, Dali Door, Tycoon these brands, neighbors said that these brands are cost-effective, I went to the market to see, it is really good, I also checked these brands on the Internet, the reputation is very good, some of them are still on the list of China's top ten brands of anti-theft doors on the online shopping and purchase of the top ten brands, are big brands, You can rest assured if you buy it.

Panpan security door should not be bad money.

Of course, the key is arc-shaped, this lock hole is more difficult to be opened than other forms of locks, first look at the lock cylinder when choosing the lock, the lock cylinder should be pure copper, and there should be no sense of shaking after the key is inserted into the keyhole, and then the lock body part should be made of thicker steel, now some manufacturers in order to save costs have turned the steel into an iron plate, which should be seen clearly, the anti-theft lock of this brand is good, I and the people around me are using, and they have been used for many years without any problems, You can go to a regular hardware store or lock store to buy in case you buy a fake, about 100 yuan.
