its a 1999 buick park avenue. but anyone with a GM vehicle should be dealing with the same basic principles. does anyone know how to change this? the book says the 'keys #1 and #2 are preprogrammed to control driver #1 and #2 but can be reprogrammed if desired.' it just doesnt say how! i use both keys, i want my car to work gosh dangit! true i could just set #1 and #2 to the same settings, but that doesnt remember radio and heat settings etc etc. anybody know a fix?
