You have another 122 at home, no? Maybe take a door panel off a spare car, and make a custom 'slim jim' type thing that works on your spare car.. practice with it when you can see what's going on, then try it on your care.

Were it me though.. I'd try to pry open the front quarterlight window. I've successfully gotten in that way many, many times. Maybe have to bend the latch tab back to shape when done.

In doing that though, I've also broke the glass once, and the upper hinge once. Don't pry on the glass itself.

Oh.. first thing I'd try actually.. try all other similar keys you have..

Good luck!
