Know it's right. And send that puppy home with either the Green or Grey Lock tight.
Green is for races and such, Grey more for keyways.
Just like Chris said it'll be dang permanent. In a pinch though heat will release to bond. You can put enough directly to the race to break the bond. The housing (edit: or carrier) would get warm but not enough to damage it. The trick is get in, get the race hot, and get out.
Of your doing all that you need a new one anyway.
