ok i followed the instructions on how to remove the tumbler cover and the cover was unscrewing until i reached the key head and i couldnt move it anymore because the head was in the way so stupid me takes the key out and tries to continue to unscrew the cover but now the cover wont move and the tumble is in at least 2 pieces inside the cover. i can get the key in there but it wont turn so i cant get it back into position 1 and start over. anyone else have this misfortune? ive been at this **** since 1pm. the car is an 87 300SDL
