2011 chevy cruze, remote start

just put a remote start on 11 chevy cruze . used a av4103 and dball. everything works great but customer wants it through factory key fob and i can not get it to work what so ever. any tips or how to on this particular car? thanks alot

The owner wants to use the GM remote to activate the RS? Do you mean they want to use the GM remote's 'start' button...or just use the GM remote to activate the 4103? If they just want to activate the 4103, you would use the lock leg of a door actuator (BROWN / yellow at BCM in that 11 Cruze) to trip a relay. The relay would convert the positive pulse from the lock leg into a negative pulse, connected to the WHITE/ blue activation input. When I do a lock/lock install, I always set the unit to require three pulses to activate. Owner presses lock three times, first locks, second confirms with horn honk, third confirms again with honk and starts the car.Installer, IT support, and FFL. I need less hobbies.

well see thats what i usually do but on this vehicle the brown yellow rests at 7.5 volts and triggers at 10.5 so its not activating my relay because its already latched. Im just doing a standard polarity converted relay. or should i do a diff setup? let me know if you have any ideas. thanks alot
