Seems to have gotten colder here and noticed when turning the key in doorlock its very firm when turning. I have tried graphite and lithuim grease as well as lock de-icer. When it gets really cold..its crazy difficult to open. Yes..i know my 07 has no power anything, so no choice but to use the key. Seems like the mechanism freezes. I am trying to find something that will work and will last. So far no luck..any great product you guys recommend? Thanks in advance!!
 
Just dont lock the door.. I know when we are expecting ice its hard enuff just getting the doors to open let alone jacking with door locks.. If someone wants in your car its as easy as breaking your window anyways.
 
any chance of warmer weather, or moving the car into a heated garage or some such, long enough for the locks to thaw?

if so. once they do. WD-40. (Water Displacement - Formula 40)
it's a Water Displacer. not really a Lube.
that's what the local Ford Dealer told us they use.

Get an old fashioned oiler and put some synthetic oil in the lock. It won't require much.

Anything will work, as it will always be thick and never reach operating temperature.

Be very careful not to get it on your paint as it is a bear to get drips or streaks off of the door.

BTW, this work on locks to your house also. Graphite and Lithium grease doesn't work as well.
I use Rotella 5w40 in the oiler that I have for hinges and locks around the house.
Works like a champ.

Just don't drip it on the carpet.
 
I have used Tri-Flow Superior Dry Lubricant

It doesn't do anything for the frozen aspect, but it definitely works well to lube the lock on older vehicles.

I would use it every other month, and apply it right before winter comes!
 
Shoot some WD40, or if you have any, lithium spray grease in there, work it a bit, drying the key until it becomes wet with oil until the key comes out dry again. Also hit the latch mech and hinges with lithium grease while you're at it.
 
Had a older Firebird with lots of frozen lock issues in the winter. Tried everything from lock deicer to Tri-flow and honestly the best success was with WD40, as much as I hate to say it! Also had good luck with Liquid Wrench lubricating oil on the trucks at work (its the stuff with cerfelon or whatever, not their penetrant).

Interesting to hear others varied results!
 
Warm can of WD-40 baby.

Just leave the can in a warm room in the house, or best on a warm air register. Sneak it out the car in your jacket, spray in the locks and good to go. Not sure I would do this to a fancy car, but then a nice car wouldn't be sitting in the elements.

There was some guy in my community going after unlocked vehicles and rifling through them for change. Always checked to see if the door was locked and didn't go any further if it was. Finally got to my car one time parked in my driveway after I forgot to lock it. I didn't really have anything valuable in there, but it didn't feel great. The thief took a roll of quarters I had in the coin box, but left behind change below that. When the cop showed up to take my report, I was told it had happened numerous times but they had a prime suspect. I guess they had to develop a case. He asked me if I wanted my car dusted for prints, and I said no if they already had a good idea who it was. It was someone only checking for unlocked vehicles, never broke a window, never looked in the trunk, and never took anything except money. I recently checked the public police logs and apparently they arrested someone a couple of months after my case.

That has the added benefit of female attractant. Make sure you get some on your work clothes.

It's -8 in Chicago and my locks frozen. I'm using Kroil later on today. It has "water displacement" agents also.

LOL. My wife hates the smell of Blaster.
 
It's probably not recommended with modern keys having chips and other electronic components in them but I remember in the owner's manuals of some of my older vehicles describing warming the key over a flame (match/lighter) for a few seconds before trying to unlock the door.

Of course, this wouldn't work if it's the rods and door latch that is freezing up.
 
Give it a shot of fluid film and work the key several times. I will lubricate the lock, drive out any moisture and make it virtually impossible for it to ever freeze again.
