I have a 2004 GMC Sierra with manual door locks and manual windows and no factory alarm. Will i still have to get the passkey immobilizer for my viper remote start? Also installing a universal power door lock will i have to get relays and if so part numbers would be greatly appreciated.

Look into idatalink. DIYers can create a free account for flashing. You'll need their USB cable for flashing and an adapter cable for the Viper.
