The position that the key is in now is the position for removing the tumbler. I don't remember whether it is position 1 or 2 but you are at or close to it. There are threads and pictures of the procedure on this forum somewhere. You insert a wire tool (homemade if necessary) into the two holes in the lock bezel and the tumbler will come out. Then you can get a new one from your dealer.

Others have posted experiences wiggling the key for hours on end, using an orbital sander to vibrate the lock while cautiously trying to move the key, etc. The key will not come out unless it is all the way to position 0 "off." If you break off the key you will have to have the lock removed professionally, an expensive job.
