Can anyone tell me how to get the part that the key goes in off my trunk and onto a new trunk? I was able to take the big mechanism off with two 10 mm bolts. But the little round part that the key goes into didnt come off with it. It stayed on the old trunk. And the new trunk had that part of it beaten off with a hammer and a punch. So I really need to get the old one off the old trunk and onto the newer trunk. What a bind I'm in now. Thanks!
