So lotsa different advice(s) here.
My specific question relates on what's good for an ignition key that occasionally jams but always eventually starts the car.
I suggest WD40 which I have used in outside door locks and should not harm any electrical wiring it might get into - vs comments on graphite in earlier posts not being good for electrical contacts.

Any other thoughts for lubing the ignition switch tumblers?

Could be your key is just getting worn out? teeth are getting rounded off etc. I found this true a few times on cars and just needed to make a new key off the original (after tearing the house apart trying to find it, LOL)

Both keys act up, one is a new key.
So methinks its tumblers sticking or the ignition assembly wearing out (40,000 mi seems too early for that).
On another forum a gentleman said never used WD40, use graphite spray. I may just check with a locksmith for their advice, hopefully they won't give me something to mess it up so they can make more money!

i had a dodge that had a defective ignition switch from the factory.

i wouldn't doubt that yours was defective either.

just replace it or rebuild it (so you don't have to walk around with two sets of keys ala chevy caprice.

also, i've never had to use anything in my (car/house/otherwise) locks and they've been working fine for decades.

A quick shot of T-40 Krown rustproofing always works for me. My buddies VW doorlock use to suffer from freezing and was hard to turn. Now it works fine.

This is a funny topic because there are a lot of strong opinions on this. Some say use nothing but powdered graphite, others use grease.

I have had excellent results using Remoil. It is a light gun cleaning oil spray with suspended teflon. The oil is not like WD-40, it will not evaporate. I have used it in sensitive electronics with great success. The excess oil will seep out, but it leaves a thin film of oil and the teflon behind. This stuff is very slick and keeps things lubricated for a long time. I use it on all kinds of hinges and locks. I think wallyworld carries it. I haven't had to buy any in a while (years) because a little goes a long way.

I don't like the left behind WD-40.

I second the contact cleaner and PB Blaster clean-up followed by a very light silicone lube on the key.

I use to use graphite...hmm maybe not anymroe after reading this.

Perhaps GC would be ideal? It works great for cars! [Big Grin]

Perhaps I can finally put my old bottle of Slick 50 to good use!

I've heard the graphite lube isn't good for modern cars. Nowadays the locks have electrical contacts that can go buggy on you if you use the graphite lube. That's why some don't recommend it for automotive locks. I'll have to check out the triflow stuff.
I suppose it depends on the lock and where it has electric contacts?

Local locksmith shop recommended triflow, said to stay away from graphite since it gums up the lock. I had a house lock rebuilt that was worn out. It was full of chunks of graphite.
Graphite is not ideal in a moist climate, because then it actually does attract dirt. It seem to work well in dry climate. Also, not very much powdered graphite is necessary to lube the lock properly. You wouldn't want to get they key greasy each time you lock or unlock you car.

One more disadvantage of gadgets more bother than they are worth. I haste the power windows I got stuck with on my Cavalier. Dumb, dumb, dumb.

Amsoil sells a synthetic spray grease. I've used it on locks before. I've also used the Amsoil Metal Protector but I don't think the film will last as long a grease based product.

I believe graphite lube is simply graphite with a solvent carrier that dries off. A little bit of graphite is good. I suppose if you lube it too often you'll accumulate a lot of dried powder.
