The drivers door on my 1995 Chevrolet van has
been trouble, since I got it. The keyhole turns,
but the latch on the edge of the door is miserable
sluggish. I've tried WD, Silicone, white lithium,
atf, and gosh knows what else. Tried cleaning it
with brake cleaner, etc.

What's a good lubricant that lasts more than a
week? I spray it with stuff, cycle the inside lock
button up and down, and the lock frees up. A week
later, it's nearly impossible to open from outside
with a key (the latch part is sluggish).

I think the last time this happened, different
vehicle, I had to take the latch out, and scrub
it with hot water and brush and oven cleaner, to
clean it all out. Can't remember what I used for
lube.

What works?



Take it to a lock smith (or do it yourself) for a good cleaning, I expect
that someone has been using replacement keys made of aluminum.

The problem is alumumum dust oxidizing and gumming up the works. My son is
a lock smith and alumimum keys are the best thing that happened to his
service industry. Easy to fix = excellent money.
