I installed a remote starter on my 1995 Chevy Monte Carlo and it has the GM VATS anti-theft system (resistor pellet in key). I bought an Autopass interface kit for this. It has 10 dipswitches with tons of different resistance settings for each combination. I tested anti-theft wires in my car with my volt meter and with the dial set on 20kOhm, it read 0.5202. The resistance values on my chart for the interface unit range from 0 to26486 with about 25-30 difference between each setting. I have tried setting it on 52, 516, 5189, 5214 and almost anything that would closely resemble ".5202". I know the system works because I have the bypass unit temporarily disconnected and I can leave my spare key in the ignition and the remote starter works. Can anyone help me please? What is the actual ohm value when the meter reads "0.5202" on the 20kOhm setting? Thanks.

set your module for 5189
you need to cut one of the wires in your VATS system, there's 3 wires from the autopass module the go to the factory VATS system. you also need to power the large red wire in the 2 pin plug.

I have it installed already; Red wire to +12v, green to ignition 2 wire, blue to ignition wire, violet to neg. (-) input from remote starter unit, gray and orange to computer side of VATS wire, and white to the key cylinder side of VATS wire. I tried it on 5189 before and 5214 but with both, I mash the start button on the remote and the unit powers up, my relays click, but the security light on the dash stays on and the car doesnt start. If I disconnect the Autopass unit and leave my key in the ignition, it works. I think my Autopass unit may be defective because I know the connection is being made because it still works with my key in the ignition. Any suggestions on any inexpensive VATS bypass modules to try that route? or anything else? Thanks.

Also, I assumed that a 0.5202 reading on the 20kOhm setting was .5202 kOhm which would in turn be 5202 ohm. Is that correct? Another question is that if I can't find the problem with the Autopass module, would a 12v resistor around 5202ohm work on the VATS wire and not worry about a bypass module at all? I know this would essentially completely disarm my VATS system, but i'm running out of options.

is your orange wire on the AUTOPASS connected to the second VATS wire?

I cut one of the VATS wires, and I hooked the white wire to the key cylinder side, and the orange wire and gray wire both to the computer side of that wire. Thats how the diagram that came with it said to hook it.

did u ever get the vats bypassed yet????
send me your e-mail and ill send you some info....too big to load here...
i use the AU-vats from omega......it seems to work really good for me.......did you measure the chip in the key??????????
put your mete to ohms......and touch each side of the key. see what the number is....i will try to send you the info that i have for the kits i use, see if it will helps you...if it does and u want one just let me know..... ------------- Good Luck

measure the resistance in the key. most remote start kits come with resistors to create the correct value for vats and same wire locks. wire in a relay with the resistance in line and your vats system will still be intact.

Yeah I tested the key also when I tested the wires. On the 20kOhm setting the key pellet and the wires both read 0.5202. I still haven't gotten it working yet.

you don't hook the orange and grey together, one of them goes to car side and the other goes to the second VATS wire. ------------- Shaughn Murley

Do you mean that I cut one VATS wire, hook the white to the key side, the orange to the computer side, and just remove some insulation on the other VATS wire and hook the gray to it? And does it matter which one? ------------- Donnie

I tried hooking the orange wire to one vats wire and the grey wire to the other and i even switched them but still no luck. I have tried all I know to try. Anybody have any other suggestions? Other than try a different bypass module?

why dont you just grab a relay and a 20k ohm resistor, or a series/parallel combo of 20k ohm? you dont really need the relay if youre ok with doing it that way. just cut the two VATS wires and solder the resistor in between the two decoder side wires. the relay leaves VATS in tact, soldering the resistor disables it. ------------- MECP certified installer

i thought about doing that. I need a 5202 ohm resistor (or something close to that). Where can I find a resistor like that? I have relays.

Use 3 resistors in serial connection. 4.7K, 470 and 47 ohms. This will give you in theory 5217 ohms. Since you have a 5% tolerance in the values, you can play with different resistances to get the exact value using a good DMM to read the total.
