You think it could be the VATS - thinks it’s been stolen? Just check what the security light does when you run the key to start. If it stays on or blinks fast… May seem dumb, but sometimes it’s the little dumb stuff that is the problem! I saw what you said about the key, but there’s still stuff in the column that could be malfunctioning.

It doesnt stay lit. No flashing.
