The culprit in the whole thing is that the small pin on the pin block that pushes into a small recess inside the housing will wear down and eventually start to be in the way of the sliding mechanism in the housing. You start to feel a hitch as the slide pushes the pin block out of the way as it travels backwards to unlock the steering wheel. Eventually when the pin on the block wears down to the point that the pin block will not be able to be pushed up out of the way and instead the slide buts up against the block unable to push it up out of the way and then your stuck The removal of the pin block as described in the mod means there is nothing in the way of the slide in it's travel backwards.
As I see it there is only one function or purpose of the pin block. That is to be in the way of the slide should someone be able to access the steering column to try to push the steering wheel lock slide out of the way or backwards into the housing. This security measure is not really necessary as getting to the steering wheel lock at the end of the housing and slide is nearly impossible.
