well if your key dont have the chip then I think it's your tach, because the alarm has to know when the car has been actually started, and the only way of knowing is thru the tach wire, most tach wires in cars are on the fuel injectors, look at all four of them, each injector has 2 wires coming from it, theres one wire that has the same color in all four, one other wire is different from the rest, THAT is the wire you wanna tap onto, knowing DEI alarms, the tach wire coming from the brain should be a thin purple wire, connect that wire to that tach wire and see how that works out.
