Lubricate key locks
 

Whats best to lubricate key cylinders. WD-40, white lithium?!?

I used white lithium. WD-40 is to runny for me.

I use wd-40 but, white lithium should be better.

Graphite!!! It wont goo all over your key, ignition, hands!!

Good point about the graphite.

and the winner is...






















graphite!

use wd-40 i did mine the other night and its works bette... just make sure u have a rag beside u so it dont run all down the paint..

Do not use WD-40 on automotive locks.

WD-40 has teflon in it, it also has a chemical to suspend the teflon and to keep it from clumping.

Look inside your door. Gee there is a teflon stop on the the key cylinder. Guess what happens to the teflon stop if WD-40 gets all over it. It starts to break down because of the suspension chemical in the WD-40.

Same thing for power antenna masts. Don't use WD-40 on a car save it for the sqweeky door hinges on your home.

Use a dry lubricant like graphite or silicon spray.

I agree, WD-40 should never go on a car. I have seen people spray it in their engine bay b/c it looks detailed on all the hoses and stuff.
Bad news: WD-40 breaks down a lot of rubber and plastic components. It seeps into the hoses and makes them soft and extremely prone to bursting.
Try inflating a rubber or latex glove and spraing WD-40 on it. 5-6 seconds later, glove pops.

What about engine degreaser? Or is that worse?(I'm talking about for cleaning the engine bay now)

Whatever you use, cleaning your locks regularly (annually?) is a really good idea. Sticking tumblers make it much easier for other keys to be used in your lock! I had a car years ago (a Corolla) whose locks gave very little resistance when inserting a key. I tried three other Toyota keys and they all worked! I lubed the hell outta the locks with CRC (our version of WD-40) and it fixed the problem completely. Mine was the only key that worked.
