Door Stuck
 

My door is always stuck to the body when its cold outside, and also my lock just doesnt turn when its cold. I know its because my car is pretty old and stuff but what can i do to fix this problem? is there something to put on the seal to make it not stick?

common problem....park your car in a covered space....or cover it...

put a lite coat of some lubricant on door seals ( like vasoline not alot ) and spray WD-40 in your lock mech or some scilicone spray works wonders

Get a de-icing solution and put that in the key slot. Chances are theres moisture in there.

I've got the same problem but way worse i dont even wanna explain.

Don't use WD-40 in your locks. Use graphite lubricant.
