H1 Hummer with key stuck in ignition won't turn to lock
 

I have a 2003 H1 Hummer and for some reason the key will not turn to lock or come out of the ignition. It sometimes would do this but with a little bit of wiggling it would pop right out but now it is STUCK!! I've tried moving the gears around, moving from HL to H to L, etc. What do I do? What is causing this? Also, my CTIS tires are starting to deflate to being FLAT when I drive it only!! If it's in the garage it's fine. It's technically just one tire but thought I'd mention it. I live in a rural area where I can't just pop on over to my local mechanic for a quick fix. I need a specialist magic mechanic to work on these beauties!! Thanks so much!

MOVED. The new Member section is for "hello I'm a new guy" intros, NOT tech questions..... just like it says at the top.

Likely need a new ignition switch.

Welcome to HF.

My 03 has the same problem with the key. Wiggle the steering wheel back and forth and it should release the key. It could possible be the shifter being out of ajustment also. As for the tires going flat you may need new hub seals.
