A locksmith at an auction will make you a skeleton key for around $20-$25. The neat thing about those is that they open all models that used the same locks...
I had one for an FJ60 cruiser that every cruiser i tried it in (4 of them), it would unlock it. The guy here at work with a FJ60 was kinda nervous after i showed him how easily i could get into his car, and how simple it was for me to get a key made to start with.
Call a locksmith.
