the top half of the key has the chip in it so dont lose that part!the key can be removed by drilling a small hole up inside the barrel sometimes i ahve dont it before and poke the broken key part out or buy anothe lock set and take the chip out of the old key and tape it to the top of the new key.or if your new key has a chip in it take it out and replace it with your old one.
