Calling anybody to come to your house to do anything costs plenty, just to get them there. OK, Dh just broke the key off in the ignition of his antique truck with his knee, when he was in an accident. The body shop guys took a very thin blade knife and slipped it in a tiny bit alongside the key and began tipping the point, forcing outward on the key. Oh first they sprayed WD 40, or graphite might work too, in side, so it would slide easily. Also, a stiff needle might work. Maybe use two, one on one side and one on the other, pressing towards each other.
If that doesn't work, it would be cheaper to take your items to the locksmith probably, if you can.
