ignition problem. key wont turn. need some help
 

just changed my oil and went to start my car to check for leaks and the key wont turn. as anyone from the northeast knows its been colder than -10 the past couple days, so i dont know if my ignition switch could freeze or something. i was wondering if anyone else had had this problem and what i should do. thanks

Don't mean to state the insanely obvious, but try moving the steering wheel from side to side.

thats exactly what I was going to say. but if you think your lock is actually frozen (which could only happen if you interior was exposed to the elements overnight) then use lock deicer. just basically graphite, works great.
