Probably just once.
Take a 6B pencil for drawing, use a knife to gently scrape the refill to get as fine the refill powder, gently blow the powder into the lock core with a paper roll, and then use the key to turn back and forth a few times. This method ensures that the lock cylinder is lubricated for a long time, and the results are excellent.
Who really repairs the lock cylinder, basically no one repairs it, because it can't be repaired, it's better to change it.
There is no need to change the lock if the lock cylinder of the anti-theft door is broken, there is a lock cylinder sold in the store that sells locks, according to the model of the lock, buy a lock cylinder and replace it yourself. It's as simple as removing the screws on the four corners of the lock inside the door to remove the lock cylinder.
The fastest way is to reset the pins, if you can't reset them, drill the lock cylinder with an electric drill, take out all the pins and then unscrew the lock cylinder to replace it.
If you don't get some oil, you won't have to ask someone to get it. >>>More
