Logically makes sense.....but I tried it a couple days ago on my previously lubed and once again gummy driver's door, and with one shot of the aerosol in the cylinder, the lock operates as if new.

Thanks Rob.
Good to know.

Good to know thanks, and to add if you have an alarm then using the deoxit with the spray tube,
this should get the deoxit to the rear of the lock and clean these contacts

Would it be safe to use Deoxit in the ignition switch too?

Mrmerlin

the ignition switch is a two piece part ,
and the electrical portion would need to be removed first then spray it. you could try it in the keylock portion

that's a real expensive option for gunk in the lock mechanism. Shoot it with carb cleaner or maf cleaner instead. Probably compressed air would work too, since the aerosol is what likely blew out the junk affecting the lock in the first place. Deoxit is great stuff, and I keep it in stock in my garage, but it is very expensive and I use it for electrical contacts only.

^This.

When I did my passenger door lock a few months ago, it had the original "gooey" lube on it. I'm not sure that just compressed air would have done it though. A few blasts of brake cleaner took it all off. I had it all the way apart. I put the springs on a paper clip, held the tumbler blades with a small pair of needle nose, that sort of thing.

I did re-lube it though. If you use anything to take all the old lube out, I'd seriously consider reapplying some sort of lube (not going to start that argument).

As far as the ignition switch goes, the directions on the can say "turn equipment off before applying...wait 2 minutes before turning it back on." I'd disconnect the battery before using it, even though MrMerlin is saying that the spray probably won't reach the electrical part without removing it.
