Door locks freeze in winter

[CB7Nub]

Basically what is happening whenever I wash my car in winter and get it dried properly my locks usually always freeze. Usually only the outdoor key holes, which I have special graphite lubricant to open the lock at freezing temperatures . Thing is now inside the button up and down locks on each door are sometimes freezing and sometimes I cannot move them up or down from inside (I have power locks and the power locks won't budge them when frozen).

So basically I'm looking for:

1) Any way to prevent the outdoor locks from freezing other than always putting in some type of lubricant?
2) Any way to prevent the inside locking mechanism on each door from freezing shut?

Outside I'd recommend White Lithium grease. Lasted me about a year before I had to redo it.

Thanks man, I'll try it and see how it works.

actually you should use silicone lube it is the correct thing to lubricate the tumblers

Oh ok, I will try both!
Thanks man.

Alchohol is one of the cheapest, and effective De-icers you can use. It works the same way that salt does at snow, it mixes with the ice and or frozen moisture and LOWERS the freezing point.

When this happens the frozen moisture returns to liquid form (As alchohol has a far lower freezing point then water) and the locks should work as they should and continue to do so.

Put the alcohol around the outside and inside the lock in question and give it a little bit before trying the key and it should work fine.
