                                                          Your options are pretty simple if your lock was not a cheap/flimsy one: either break the lock, break the thing it's attached to, or call a locksmith. If you do have a cheap lock, try inserting a thin object with a small curve to the end, and turning it.  Or buy another lock and the new key will likely fit.
