I had a used late 80s VW GTI with a starter disable switch. It was actually a circular key that would pop out under the steering wheel. The lock did a couple of things I eventually figured out… The engine would turn if it was Locked but it wouldn’t start. And it oddly locked the hood (which was a relief to discover the latch wasn’t in fact broken) My car too was never stolen but it was broken into as well.
