HUMMER H3 start up problem.

[rtramey2]

I have had my H3 for a few months now, I bought it used also. I had the same issue with passlock system for over a month when I got it. I had it in three GM dealerships, and by accident a mechanic found a recall on the key cylinder for the ignition. He replaced the part, reset the system, and I haven't had another issue with it.

I know it doesn't have anything to do with the door, but it is doing the same thing mine did. It might be worth a try.
