Unlock new possibilities

MK Express creates complex Master Key Systems so easily that you don't need to know master keying to use it.

Just tell MK Express what hardware you are using, set out which keys work which locks and then press calculate.


Not just inline and SFIC

We also create Master Key Systems for more interesting locking hardware like:

  • MR Group
  • Ultion WXM
  • M & C Holland
  • Mottura C28
  • Corbin Russwin System 70 IC

Expand your existing master key systems.

MK Express has a problem solving engine that can understand and expand on your existing Master Key Systems, even paper ones.

This engine will also handle you entering the cuts manually for some keys, and then calculating the others to match.

Have a Master Key System created by obsolete software?
MK Express can expand those.
