that did come to mind, just thinking if any better ideas out there.

Two great minds, none better mate

done, ground the burr out a little bit and got a small screw driver to gently pry the remainder and the key managed to fit in there, used pliers to turn it as it was tight as the plate was bent, got it out, dismantled it all and hit the plates flat and reassembled and perfect again.
