2002 Chevrolet Astro

ok I did the aps 785 on this van and i still cant get the door locks to work please help. the van has the factory keyless entry were if you hit the unlock once it opens only the drivers door and if you hit it twice it opens all doors. I have tryed several differnt ways to hook this up and was only able to get it to total lock like normal and to total unlock if i double click the unlock on the alarm. the silly thing also burnt one alarm trying different wiring techniques. please help guys ty mememe

The wires are lt.blue for lock and white for unlock, they can be found at either the drivers kick panel or at the bcm located above the radio and the require a +12V to trigger them. Refer to this if you need relays
If you are having problems doing a progressive unlock then you would need to wire the lock to the lt.blue and the second unlock to the white. You would then need to five-wire the drivers door unlock wire which is a grey wire in the drivers kickpanel, so do exactly what the unlock portion of this diagram to the drivers door motor wire

Do you have the door lock interface they make to bypass GM factory keyless entry??

Just a thought

I did understand the question. You are having trouble hooking up progressive unlock(d door first push and then other doors on second push). For the locking you will need to hook the green wire from the alarm to the light blue wire of the van(lock switch wire). For the drivers door you will need to wire a relay using the red wire to trigger a relay that will unlock the drivers door only(85 red wire from alarm(unlock first pulse), 86 ground, 30 driver door unlock motor(grey wire in the kickpanel(it will need to be cut)), 87a drivers door unlock switch, 87 12V constant. For the second pulse you will have to wire another relay because the alarm second unlock output is only negative out so you will need to switch it to positive, 85 RED / black wire(second unlock output), 86 12V constant, 30 12V constant, 87 output to the white wire of vehicle(unlock switch wire). As for a keyless bypass, as far as I am aware there is no need for one in this vehicle. If you look in the alarm install manual it will go over the steps in the " 3 wire positive switched 2 step door locks" section, it even has a diagram showing exactly what to do.
