Hi there, new to the forum, I have an 08 suburban LTZ. Can i get a replacement ignition key made anywhere or does it have to come from the dealer based on VIN #, also how about another remote?

Is there any way to test the auto ride height system? I used to hear it(very loud sometimes) once more people got in the back seats, but i havent heard it in a while. Thinking the pump has gone bad.

Any help greatly appreciated...
