Hello Customer (name blocked for privacy),
The only thing you can do is drill out the lock cylinder retaining tab and replace the cylinder. I will send you the factory procedure for drilling this out. If you don't have an "Angle Drill", you will have to get it towed to a shop that can perform this procedure. Since your cylinder is stuck in a position other than the off position, this procedure may not work. You will have to destroy the old cylinder, so make sure you get a new cylinder and new keys before attempting.
Hope this works out for you. I've done several over the years, and I know they are not fun.
