yeah, it was like popular electronics, IIRC. my dad built one and used it for the garage door opener, but I think one of the main applications they listed it for was a security system for the car.
This would have been back in 1988 or so...
and the output of that circuit was enough to act like you had pushed a button, so you'd probably need something to put the car into the 'run' position or build a secondary circuit to use the momentary output of the keypad to put the car into the 'run' state, and then use the push button to crank the starter...
I knew a guy with a Fiat, he had to half-ass the wiring and use a house light switch to put the car into the run state. he used a second house switch to crank the starter... he had nothing but wiring problems with that car...
