How to break open the trunk-lock?

Hit the locksmith and ask him what he thinks. They are miracle workers. I lost my trunk key and went to Blaine Locksmiths. I told him what happened and asked if he had any magic he could work. He put a key blank in a vise grip, grabbed a stool and sat behind my car. He put the key in, looked at it and hand filed a few spots. Put it in, filed, put it in, filed, etc... After the fourth filing he put it in and turned it and the trunk popped open. How many do you want, he asks with a smile. Cost me $25 and it was money well spent. I bet they would have some ideas on what you could do. Can't hurt to ask the experts.
