The way that I have found what key is needed for an unknown Model 94, is to use a flat piece of metal, like a straightened out hair pin or something similar. Call this our shim. Start at the notch on the left side of the key hole. Slide the shim around the key hole counter clockwise until it hits something. Make note of where the object that stopped the shim is. lift up the shim a little, move the shim across the object that is blocking you and continue the sweeping of the shim around the key hole. You will hit an other block at some point. Make note of where that block is. Keep doing this until you get back to the notch on the left hand side of the key hole. These are your pins and where they are located in the locking mechanism. Use that info and compare it to this chart to determine which key cut you need. Most Model 94 cuffs use the "N" key code.
