Just went in to load the van,and couldn't get one cupboard to open for love nor money.Its one of those push-to-lock knobs on it,it had seized,it wouldn't pop out.Got some wd40 and sprayed it through the crack in the door,hoping to hit the mechanism,luckily after working it for a while whilst spraying it popped open.Did them all while I was at it.Just thought I would mention it,as I had never thought of greasing/lubricating them before.
Wd 40 is an oil lacking lubricant,though it works on things never put it in your car door locks it will degrease them and after a time they will jam through lack of lubricant if that makes sence..
WD40 does lubricate, it contains 15% oil, most of the rest of it is solvent & gas. The solvent mixed with the oil cleans & frees the stuck mechanism, then the volatile solvent evaporates leaving just the oil which then lubricates. Very clever stuff.
Go to a hardware shop and buy a small tin of Graphite Powder and a kiddies art brush.
Try and dry out those locks that you have sprayed with WD40 and then by dipping the small brush in the Graphite and "painting" it onto all the moving parts of the lock that you can, your locks will stay well lubricated for the next 15 to 20 years.
What i really should have said michael is, thats its not like a thick oil which would say, be used to oil a bike chain it is a mineral oil and mineral oil is light.Sticking mineral oil into a cars door lock will lubricate it but not for long, grease is prefered, wd40 will dissolve the grease in the lock and sooner or later the lock will feel stiff.Please try it.
We have them and find that they often stick...but only because they have unscrewed. Each time you press there is a little twist and slowly they come undone so the opening mechanism of the push button does not catch to operate....so it seems

Whilst the 1st part of this is true, I believe the oil in the WD40 is very light & is not of a sufficient grade to coat mechanisms effectively for prolonged periods.
It's fantastic stuff for freeing things up but I have found that unless another lubricant (heavier grade oil) is applied afterwards, the locks don't stay free for very long. How long would depend on conditions - it's damp here !

Aerosol motorcycle chain lube is useful stuff for the same reason- it comes out of the tin like a thin oil so it penetrates mechanisms, but then the solvent evaporates and it thickens to a grease to lubricate for a long time without drying out.

I refer you to.this
For michael..
thanks good read.when i lay up the van for winter and after all jobs done i put a finger tip of grease or Vaseline on top of the external locks where the key goes in to stop water from entering.march time a quick wipe and away you go.
