My '03 Alero has keyless entry, but not command start. I was just wondering if its possible to walk into the dealership and buy a plug and play system for upgrading to command start? For example just buying a different module and fobs? I would assume all the wiring is there for the system, just the module needs to be changed. Alot less hassle at the factory and dealerships that way, I would think.

thanks for anything!
