I have had good luck with WD-40 on all kinds of locks but I live in a failry dry place.

I fleel the WD-40 has enough fluid volume and some pressure that it flushes out metal particles. It also provides some minor rust resistance and lubrication.

It sure works well on the bunch of Chinese Pad Locks I use on my Gates and Sheds and so on.

I have also sprayed WD-40 on keys and inserted them.

Note that graphite offers no rust protection. Lubricants can freeze in cold weather, dry out and leave a sticy residue and or dirt gets stuck to them.

WD-40 does not seem to leave much of a residue on it and the rust protection dimishes over time; I think it eventually evaporates. In the mean time on pad locks you get about 2-3 months rust protection depending on if it rains or not.

This is why I love my old Silverado,
I just googled the ignition lock stuck and searched, then watched a few youtube videos,
no- I wont call a locksmith for $160,
No I DEFINATELY WONT tow it to a dealer for a $320 bill.
I just push it down while wiggling a little to get it to operate.
I will order a new replacement for $33.00 tops second day air if it gets too worn for the pin to not come out of the detent..

graphite, spray lube, heating it up, all that is nonsense.


its real simple when you know whats going on-with a Silverado.
you just take the top and bottom plastic covers off ~ and you could get at the pin with a pocket knife to work it out of the detent if you were stuck in a parking lot someplace
