Remote start won't work without key

Yes, it has the chip in the key.  I took the unit out of my old car (it was in it when i got it).  It had a resistor at the end of the two white wires in the orange installation, but no relay was hooked up to it and it worked fine in that car.  I went and got the resistor out of that car and tried it in my Caddy, and it didn't work. 

Also, I ran the trunk wire all the way to the trunk and hooked it up to the black wire on the trunk release, but it doesn't work either.  I tested the wire from the remote start, and it IS sending a ground when I hit the switch.

Thanks to everybody trying to help.  Believe it or not, I've installed a few alarms in my day, and never had this much damn trouble.  I'm about to say screw it, and just use it for the keyless entry!

you will need to bypass the VATS system....Good Luck

Always check info with a digital multimeter.

I promise to be good.

You need to measure the resistance in the key for your current vehicle. It will most likely be a different value than the resistor in your old car. You can hook it up the same way as the old car but the resistance has to be correct. If you just wire it across the 2 wires as it was before then you will be defeating the security of the key resistance. In other words, any key cut the same as yours will work in the ignition even one without the resistor pill in the key shaft. This is acceptable but it is just one less security feature that your vehicle will have once it has been permantly bypassed. If you wish to maintain the security feature and bypass the key resistance only during a remote start attempt then follow the diagram below using a relay. GM V.A.T.S. Bypass Diagram

Your better off just running it to the push button switch up front (glove box, most likely). You should use a relay that makes a good solid connection to ground when you pulse it from the alarm's trunk output. The output itself is probably not strong enough to trigger the opening of the trunk. The output has a low current output capable of driving a relay. Follow the first diagram for a NEGATIVE trigger trunk pop relay. Negative Trunk Pop Diagram Have fun and good luck. Steve
