try this first - put the key about 1/4 of the way in and spray some WD40 into the hole. After listening to this forum I put some auto trans fluid into a squirt can and use it for this purpose. I'll swear that it seems that the ATF works better. Before you go to all this trouble though - does the key turn at all? If it does then the problem is somewhere else.
