If you truly want another wheel lock key, stop reading now. Because I dont know and can't help there.
However, if you're still reading.....
Are you sure you want to get a new key? Are you really that concerned about wheel theft? I've had wheel locks on cars before, and it's been my experience that those things only prevent one person from removing the wheels: the owner. Wheel locks break, get lost, etc. I really believe they are much more nuisance than they are worth.
If you live in a tough neighborhood and theft is a real concern, then keep the locks.
If you are not worried about theft, keep your car in a garage, and don't commonly park in bad places, then place the wheel locks in the trash and replace them with lug bolts. Any competent tire shop should be able to help with that, even if your key is broken.
That's my $0.02. Take it or leave it.
