To John Saeli

As to possible repair... On my 2470 the Left Hand (most used) door outside handle was really sloppy on it's pivot. Causing the operation of the latch to be intermittent. So I removed the little panel from the inside, at the handle area (with the door open) and found the handle shaft to be supported by a welded-on collar that was worn oversize on it's I.D. This allowed the handle shaft to wobble badly. So I simple found a small bushing to insert which minimized the shaft looseness.

I looked at my Case parts manual exploded view of the door handles and latches and can determine that access to the handle and latch mech is from the inside through that removable cover I spoke about earlier. If you think these pictorials can help you I'd be glad to scan & Email them to you. Just reply with your address.

So, I'd say at this stage you have two options...
1. As John suggested earlier, perhaps you can turn the broken-off shaft from the outside. Since it's 1/4" square I'd try a 12-point socket to fit the 4-point square shaft. If there is not enough shaft sticking out or of the handle base plate is in the way... just grind it off with a sidewinder. The replacement handles will include baseplates. If you do this you will need to also replace the screws & nuts mounting the handle, since they will also be ground away. 2. Use the Ol' coat-hanger method... fish a stiff wire behind the lower front of the door, through the door jamb, by flexing the door outboard with a flat pry-bar. With a bent hook on the end of the coat-hanger try to loop onto the inside handle and pull the handle down to open the door. Good Luck.

By the way... I don't understand why you think new handles with locks will help you ??? As I said earlier, for removal and replacement the handles mech must be accessed from the inside.
