how do i unfreeze my car door locks?

The best idea would be to heat up your key with a bic lighter some what to get it warm/hot and then stick it into the lock slowly melting the ice. Once you get home, spray WD40 to prevent the moisture from formng to start with. Good luck

You can go to Car Quest, NAPA, WalMart or any place with an automotive department & purchase a small bottle of "Lock Deicer". Inexpensive & easy to use. Or; if you have a hair dryer, set it on medium heat (you don't want to damage the paint) & it will have the same effect but will not usually remove the moisture & will likely freeze again. Which ever solution you use when the locks are unfrozen use WD40 to spray into the lock to disperse the the moisture. Use the little tube extension that comes with it to get all the way into the inner lock mechanism. Then you should be good to go.

EVERYONE on my facebook is telling me that WD-40 is a bad idea because it will freeze, They say use powdered graphite. I have bought the WIndshield WIper De-Icer fluid and you could easily pour that over the top of the door frame. And they sell lock deicer's at Walmart and hardware stores, Buy it at the start of the winter season so that you're ALWAYS prepared.

My daughters car did this last week..I warmed the key with a lighter. After a couple trys at doing this the car door unlocked....turn carefully though...not to bend your key.

Avoid freezing in them by covering the car with something

Hair Dryer.

A nice one would melt away the ice.

Next time, cover you car with a car cover.

Take a Hair Dryer To them.

Any hardware store has a small aerosol just for this purpose - just don't keep it in the glovebox, if you get my drift...

Use a blowtorch and hold it nearby (not close enough to blister the paint though!)

You can also get chemicals that do it, I think WD40 might help.

You could burn the doors off
