xantia key wont open doors. Just turns in the locks.

Thats because these keys use four faces instead of two.....the cutting machines that most locksmiths use can only do the normal faces, they can't put the key blanks in sideways to do the two flat faces, so they have to do those ones by hand.

I have watched these keys cut with no problem. You cut each of the 4 face's one at a time using the same machine you cut Yale type keys with.
