How safe are these products? You can lubricate a door lock without chemicals or special tools. You will need a simple pencil to rub the key till a thick layer of granite appears. Then, insert the key into the lock, and leave it for an hour. The granite will be deposited into the lock, and a thick layer will remain on the key. I learned this life hack from the emergency locksmiths se20 agency. From the start, I was against any chemicals on my lock, and using a pencil to lubricate the keys seemed the safest way.
