Anonymous users2024-01-24Pro, this method will try to solve it like this, okay? Try to get some lubricant (graphite powder, if you don't have it, you can use the powder in the 2B pencil lead), put the lubricant on the key slot, slowly feed it into the lock cylinder little by little, and open it a few more times. However, if you have oiled it, it will be difficult to do, and it is easy to stick to the ash and get stuck, so remember that the lock cylinder is difficult to open the door, and you must not be oiled, but lubricant.
If this method does not work, then it is likely that the tolerance between the lock cylinder and the lock tank (hoist lock) is not good, or the material is caused by thermal expansion and contraction. There is no solution to this, maybe it will get better in a few days, maybe it will never get better. You can only change the lock cylinder.
Your lock may get into the water a lot! Try spraying with the WD40! This is a rust removal and anti-rust thing!
