This sounds like there is an issue with the vehicle recognizing your key. I would recommend contacting your local dealer for a diagnosis. I can also look into this further for you with your VIN. Please feel free to contact me privately. Thank you.

I doubt it's your key it's the fact you don't have the FOB. The fob used designates what driver 1 or 2 based off the order you program them. Worst case is somehow you trashed your ECM, try mashing the button labeled 1 on the door and see if that displays driver one on the DIC if it does then your problem is the key fob and you should probably try and pick on up they aren't expensive about 30 bucks. If that doesn't work your probably going to have to take it to a dealer cause the likelihood it is an ECM failure is pretty high.

I tried it with a button on the door, and nothing is changing, and nothing appears on the display when you press the button. I recorded video, to show you "signs" after switching ignition off. Every time, these signs are different, you can watch it on this video.
Is this problem with engine control unit or with body control module???

Default Help same thing is happening to my hummer

So this happend for the first time tonight with my 2003 H2. It wont start at all and is at a school parking lot. I did everything i could think of to fix it and it sounds like you have the exact same problem.

Did you find out the specific reason and fix the hummer?

My friend, there was a lot of problems on my hammer, water was everywhere, in passenger's door, driver's door, engine control module and body control module. . Body control modul is located behind instrument panel, and it's hard to take it of.
