I have a 2002 Envoy and I have the same problem. I have to insert a pen or pencil in the hole right up under the ignition switch and push a wire to get my keys out. It gets old but what caused this I have no idea. I think it is something in the shift linkage.
take it to the dealer and wait for the bill $$$$$$$$$$.
after replacing the stearing colum what would cause it not to start. You may have disconnected the ignition switch.
Is it an "after-market" radio? It sounds like it was wired to a "hot" terminal that is not controlled by the ignition switch.
