RTH!- really cold this am--2. Went to start my truck and the key physically won't turn in the ignition! The electric door locks work, seat adj power work and I even removed that little plastic square by the shifter so I could move the transmission to N and try starting it in Neutral. Nothing! I have a space heater in the car to try and heat it up- got to get to work. Any ideas? It's like it's the wrong key.
