Have you thought about a light dab of super glue on other key half, insert carefully and let set. Pull broken key out.
Very small amount of glue. Make sure key hole is open. Have handle of key inserted with proper orientation of the break.
If it is broken off too far in, wouldn't recommend using glue.
