Replying to PROBLEM I NEED HELP WITH ASAP TIME SENSITIVE!!!

I am leaving for windells on monday and I have lost the keys to my YAKIMA skybox with my skis in it! my friend is currently looking for the keys in his woods where I think I lost them, I doubt the luck there. I need to know a way to get into it, I am going to Kittery Trading Post (a camp store were I bought it) to see if they can open is, but I think it takes a week to order a new key.  So I am wondering if anyone has ideas to open is, maybe there is a trick to open it locked, I dont want to have to resort to breaking it open with a hammer, but I am going to as a last resort, but I dont want to.  PLEASE POST SOMTHING TO HELP ME!!!!
