Thanks for the correction. However, I have seen Biaxial/Omega... I also
can order these from a locksmith "superstore" in my area.
PS: Biaxial servers two things: One, it offers many more key
combinations than non-biaxial, and two it extends Medeco's patent on
keys, which IMHO is important.

If you know what you are doing, you are not making progress...

So Biaxial are available aftermarket in both single and multiple keyways. M4 their latest is really the only protection against aftermarket keys IMHO. As a primus dealer the Classic keyway thats backwards with C, E, F etc are available blank aftermarket. The Everest S29 is still patented but who knows for how long.
