That is the wrong type of key for that lock. In this picture, the top two tools are bicycle spokes bent to pick the lock, then there is a key I was making, and the bottom is a file I used to cut the key.
The important parts of the above pictures are the picks (you can find threads here on how to use them) and the key. The key is the type you are looking for.
Good luck!

Just when you finally think you have learned it all, that is when you learn that you don't know anything yet.
