now thats its in the 20s and lower..i have to resort to climbing through my trunk to get in my car..lighter trick hasnt worked and the deicer only works half the time..any of you mustang guys know any other way

 

Your doors are frozen shut? Is it the locks or do you have the problem where there's water along the bottom of the door that freezes?

 

Are you saying your door lock is frozen? And the FOB won't unlock them? Have you tried spraying deicer into your lock? Lock-EZ? That works on my g/f's Honda that's been sitting out in subzero temps.

 

Eloborate please it was -12° here last week and no problems

 

Climbed through your trunk? hee hee I giggled a little. Sorry.

 

elaborate? ok i stick the key in and it doesnt turn..as ive stated the deicer doesnt work but maybe half the ime..i even put some regular lubricating oil in..only have the problem when it gets in the 20s and below

 

yeah climbing through the trunk sucks..would suck worse if i wasnt fit and out of shape

 

Ive never heard of this problem before. Maybe try taking your door apart and seeing if there are any problems you can see.

 

well it only happens when it gets cold so im not gonna tear my door apart for something that isnt a mechanical problem..but thanks anyway..

 

Sounds like you're not getting a chance to get all the moisture out. As much as I don't like WD40, it WILL displace water. Try spraying it into the lock thru the tube AFTER the car has sat in the sun a little. You want any ice to have melted. Wiggle the tube a little while you spray. Also spray some into the lock mechanism on the door jam as best you can. Then, after a few days w/o any more rain, I'd spray with Lock-EZ which contains graphite to relubricate the lock.

I'm assuming the FOB doesn't work, either?
