1990 Ford Fiesta someone has stuffed something in the keyhole

Someone (for some unknown reason) tried to steal my old banger over the weekend. Unfortunately for them I had left the lights on a few days earlier and ran the battery dead. Sucker! However, unfortunately for me, they stuffed something metal into the ignition keyhole to try and start it and snapped it off in the process. It's right inside the hole and cannot be grabbed by pliers. Does anyone have any idea how I can get this out? The car is worth maybe £100 so it isn't worth paying £££ to have it fixed but I would prefer not to scrap it as there's still quite a few months MOT left on it. Any help appreciated.
