Unless you are able to emulate the Immobilizer route (logically, via CAN or some such bus) direct to the ECU, you would land up reducing system reliability by adding points of probable failure (I am not even talking about M$Windoze and cars!
). For example, to account for the override switch, you will have to add a relay, and so on and so forth.
Now imagine you have to make a quick start, wouldn't you find that a nuisance if you are not able to start the car?
On the other hand, cars which have a push-button start (true keyless entry types), logic is implemented in the ECU which validates all permittances before allowing Starter command and Ignition permittance to go through. In such cases, additional alternates are provided (in hardware as an ECU pin) which count towards that permittance, and one can wire one's own enablers / disablers.
