i saw how they did it and its nothing too ingenious about it, combine this with an alarm and a manual kill switch, i dont see much happening
your refering to "dead locks", a system used on either bmw, or mercs. due to this when someone would lock their keys in the car the only way to get it open without breaking the window, was to drill a hole behind the license plate.
as for demand on the kill switch the demand should definately be there, cost I could see parts at $10, relay, wire, connectors, switch. if a bracket or something needs fabrication then a few bucks more. then say $25 an hour for labor, cheap price for install and more reliable than an alarm.
