Sounds like you have a bad body control module real common for that model have seen alot of them go bad. It controls your park lock solindo keyless entry and power door locks. Your fuel gauge all your inside lights. Your security system and the new module has to be programed by the dealer or a gm dealer. You will have to have it checked out by a professionial though I have a tester body control modules for 2000-2004 L model cars v6 and 4cyl for diagnosing. Each year and engine takes a differnt one so that will give you a idea on how common it is for them to fail since a have complete collection of bad ones for testing. Let me know what they find.
