oldschool dei keypad starter kill?

Many moons ago, in my younger dumber days, I had an additional starter kill, standalone from my alarm. I was running a 93 Eclipse, had a Viper with Invisibeam sensor, and in addition to the alarm starter kill I had a keypad mounted to the dash which strictly controlled the ignition system. You had to put in a code in order to start the car. This would have been circa 1994. Anyone remember this unit, and is something along those lines made now? I could save an awful lot of time re-engineering if I could just buy iy."Always listen to experts. They'll tell you what can't be done, and why. Then do it. - Robert A. Heinlein"

dei 103t ?

They must have upgraded it. I definitely remember there being a full 12-button DTMF keypad. That's the one I am looking for."Always listen to experts. They'll tell you what can't be done, and why. Then do it. - Robert A. Heinlein"
