Use a IPP03 this will temporaily bypass the vats system for remote starting, or if you wanted to do away with the vats measure the resistance with a ohm meter "one lead on each side of the chip on the key" and look under the dash by the ignition wires for a orange loom with two very small white wires then strip the loom away and cut the wires and get a resistor within .05% of your meter reading and solder the resistor to each end of the white wires leaving the ign switch out of the loop and you will be good to go but if it were me i would get the bypass because it is self learning and fool proof with very few wires to ajoin good luck hope this helps
