Just a reminder(I remember those times too) that before the advent of immobilisers and electronic ignition locks, any car could be started in about 30 seconds with some very basic tools. Car theft has been absolutely rampant until the mass adoption of immobilisers where it has literally dropped off a cliff - it hasn't stopped thieves completely of course, but it's very much the case of electronics reducing crime by an order of magnitude(at least here in Europe).
