I have a viper alarm 791XV with remote start. I need a replacement remote, this is the info on the back: RPN 479V/P/C 2(66) CODES FCC ID EZSDEI478. In addition to the remote start feature, it can let my windows down individually without disarming the alarm. It can let my windows up individually when the alarm is activated. It 'pops' open my driver door and it also controls a motorized system that opens and closes the doors in the back of the vehicle.(97 Chevy Suburban) What is the difference between remotes that say DEI or LCD, or is there a difference? Will the new remote come with full instructions on how to program ALL of the features I've stated? Please help.
