The same thing happened to me. There's a lot of options. A locksmith can take your lock apart and
take the busted door pieces out and put it back together. Heck, if you like playing with tiny parts and
springs that have to go back together right, you could probably do it.

I ended up getting a whole new tourer lockset from HDL for around $130 and had an
adventure changing out all the locks. The ignition is sold separately - if you don't mind
having a different key, you could get that - it is one of the easiest to change out.
