If you're talking about the modification (PERMANENT) fix, it's a piece of cake once you've done it but that's not much help is it? If you have to drill out your ignition pin make sure to use an extra hard drill bit or one you don't care about (or a dremel with grinder as some people claim).

I tried to figure out the effects and risks of removing the pin and spring from the ignition having the fear you described of the wheel locking unexpectedly. All ingenuity points to the pin having the opposite purpose. It looks like the pin is a redundant lock on the steering wheel to make sure the steering CANNOT be unlocked (say by a thief). The key/tumbler itself - not the problematic pin and spring - seems to hold the locking mechanism out of the steering column. Nobody here has reported a problem since.

Mine has been fixed for about a year now and works like a charm.
Good luck.
