Since you did it yourself you don't have to worry about a comeback.

Instances of these events are about evenly distributed between tumblers that are wore out and steering lock gearing that is wore out. Really a ***** to guess at which is bad when the problem isn't occuring OR when it is, as the symptoms are the same. It is possible to verify a worn tumbler by the loseness of the hardened plate the key is inserted through.
