If you're a Medeco dealer and you need to buy locks for a masterkey system the factory will generate it for you.
I'm guessing they declined since they already have a program to do that.
Because of fore and aft cuts Medeco Biaxial and m3 systems have varying MACS, add in masterkeys that can have more than one cut at each pin position, it can get complicated making a Medeco masterkey system. While there are plenty of competent locksmiths around the country, considering that the trade is largely unregulated there's no way to be sure a locksmith will do a masterkey system correctly, Medeco or otherwise. Doing it wrong can reflect badly on the manufacturer as well so I'm guessing that's why Medeco will design the system if you're buying the locks for it. I can't remember if there's a fee, but if there is I don't think it was very high.

If you look straight down at the key the cuts are not perpendicular to the length of the key, like in a regular key. They are angled, and the chisel shaped tips of the pins fits into that angled cut, turning the pins so the groove in the side of the pin lines up with the legs on the sidebar. You don't have to rake the key, it should work very smoothly. If it doesn't then the key was probably cut wrong. With the profile of the key cuts and the way the pins sit in the cuts, the pins and key can receive very heavy wear before it would ever cause a functioning problem.
