The correct way is to use a pencil to scratch back and forth on the key tooth shape, grind out some pencil powder, and then insert the side with pencil powder into the lock cylinder, pull back and forth, it is very slippery, do not use cooking oil, this will damage the lock cylinder, and when the weather is cold, you will be prone to problems
Remember not to use any lubricating oil or edible oil for the lock cylinder!
