What s wrong with the security door at home that is not easy to lock

Changing the whole lock and changing the cylinder is not the same concept! You don't necessarily have to use Buyang's lock, you can buy a lock cylinder and replace it. But it is best to change the lock cylinder with a better one, and the miscellaneous brand, the general lock service life, and the probability of failure are not guaranteed.

It's okay to change the whole lock, but I'm afraid that the model is difficult to match, and it's relatively simple to change the lock cylinder.

The price of the lock cylinder is dozens to hundreds, you can buy a 180 yuan lock cylinder and replace it, and the general building materials market sells it.

In real life, when people encounter that the door lock is not easy to open, they will generally lubricate the lock cylinder with oil, although it can solve the problem, but if you do it often, a large amount of dust will enter and mix with the oil, which is not good for the door lock. I think the best way to do this is to scrape the pencil into lead powder.

Lubricate the lock cylinder, which works very well and does not damage the door lock.
