you can add as many gadgets to it as you want(card swipe,lazer scanner,finger print, blood sample, etc) but in the end its a simple starter kill relay . that is very simple to bypass.
any starter kill relay will work if installed properly and hidden with an aftermarket alarm.
because the relay is normally open, which means when the alarm is armed the relay is resting in open circuit position so even if they remove power to alarm brain the starter will still be cut. the only time starter wire is connected is when alarm is disarmed or remote starter is active.
that stupid keypad will only deter noobs. and they will end up tearing your dash to pieces trying to find the wire or whatever they think they looking for to start the car.
a pro would have it bypassed within seconds just like a typical starter kill.
