Broken Ignition Subaru GL

[jread]

Have a broken ignition in my Subaru GL.
 

It has an indexing issue and has no spring on the "start" setting. 

Basically the key just floats around and you have to start the car and then bump it back off the starter into the perfect place. 

Is there a way to repair these or am I screwed? 

I'd really like to keep one key for the doors and ignition.
