Key Wouldn’t Turn On?

[Mixagon_imp]

Just something on locks, my front door lock became harder to operate and it's good quality, took the cylinder out ( with the key in it to prevent losing the slides ) and despite lubricating it regularly it was dry in most places.
So i shined up the surfaces of the barrel, applied gearoil liberally and re-instated the lock, it works very smooth now and the extra benefit is the key will wear less because of the lack of friction on the cams, i have no experience with graphite but the lubricant must be in all the working area's of the mechanism and in my case more was better.
Much overlooked these locks, same applies to all my vehicles.

I know a lot do but I have always been told never to oil a lock because in time with dust and grime it makes the levers stick so I've always used graphite which I blow in on a piece of V shaped paper and put some on the key as well. If someone has oiled it before the graphite would cause more problems so I only use it on a dry lock.

Re the oil method.. Years ago at a workplace the front outside gate had many keyholders and was used many times daily and was oiled almost on a weekly basis because of the weather and stiffness but still had to be replaced regular due to failure to unlock.
The main complaint about the lock was oil coming out on the key and into peoples pockets/bags etc.
Do you find gear oil comes out on the key ?
