So this morning the driver side door would not unlock. It took a 45 minute drive to work in order for it to "unfreeze"

at lunch, it was ok. but when i left work, the lock was "frozen" again. this is the first time it has happened. it was not too cold today, its been colder and i did not experience any problems. i have also washed the truck and had it get cold over night, and still no problems.

it did not turn with the key either. since it eventually unlocks, its not a latch/rod problem. if the key worked in the cylinder but did not unlock it, then that could have been the problem.

so, anyone have any intermittent problems like this ??

Maybe the tolerances in your lock cylinder are a little too close? Try some carbon spray in the lock... Might help, won't hurt.

Use WD-40. The WD stands for water dispersant.

update **

same issue this morning, lock was "frozen" tried some wd-40...........that did not loosen it up, did not work with the key either.
it "un froze" just be fore i got to work ( about 45 minutes of running / driving )

it worked with the key after i shut the truck off when i got to work. we will see what happens at lunch time and then when i leave for the day...............................

can it just be the weather ? like i said, it was maybe 10 or 12 this morning. it has been 0 before and i did not experience any issues..............

completely aggrivating.

A can of the compressed air for a computer with the straw will move the water out too.
Then use WD-40

Please figure this out. I'm in the same boat as you right now. My lock started freezing after I washed my truck a week before it started to get cold at night. I got frustrated after many days of crawling through the passenger door, and decided to take the door apart. I had already put lock de-icer in the key hole with no luck. I W-D'ed any possible moving part or mechanism inside the door panel. The temperate warmed up for a few weeks, so no problems. Last night the lock froze again and was still frozen on my drive to work. Like you said, it takes a good 20 minutes of thawing the car out from the inside until the lock decides to work. The worst problem is even if I don'l lock my doors at night, the lock/handle will stay open as soon as I go to close the door. The only way safely shut my front door is to lock myself in...but anyway, I'm with you..wtf. Need some help.

Is it possible for any moisture to be inside the cables running from the lock/handle to the interior lock?

This means you removed most of the water, but not all. Blow it out with the air gun and put in more WD-40.

i have not any any problems since i left for the gym wednesday night.... it has been in the teens for hi temperature the past few days..... no problems.

by friend who is a mechanic said there may be moisture building up, thats why it " thaws" after driving with the heat on.

so far so good,
Clint, thanks for the helpful info

dj, good luck with your truck
