G) Repeat step 5 for the left cuts. Remember to duplicate only one cut a time and do not cut over the top
of the “V” and into another adjacent cut. When you have duplicated all the left cuts lock back your
carriage and turn OFF your machine.
H) Rotate the stylus and rotate the cutter head and lock it in place for Right cuts.
I) Repeat step 5 for Right cuts. Remember to duplicate only one cut at a time and do not cut over the top
 of the “V” and into another adjacent cut. When you have duplicated all the Right cuts lock back your 
 carriage and turn OFF your machine. 
Cutting Medeco Hi-security keys is simple and easy to do with the Rytan RY256 Key Duplicating machine. 
Keeping your machine clean and paying attention to detail and following the simple steps outlined above 
will insure quality Medeco keys cut at maximum profit for you. 
NOTE: CUTTING STEEL KEYS IS NOT RECOMMENDED 
Cutting steel keys will accelerate cutter wear. Some steel keys will ruin your cutter wheel with just one 
pass. 
NOTE: Some automotive presentation keys are made of hardened steel and can ruin the cutter instantly! 
Don’t be fooled be the decorative Gold, Brass or Silver plating on these keys. 
Suggestion: keep a small magnet near your key machine to identify steel keys. Before cutting a
steel key try filing a small groove where one of the deeper cuts will be-if the key won’t file easily it won’t 
cut any better in your key machine and will most likely ruin your cutter! 
6. Vise Jaws
Choosing the correct upper vise jaws. For most key cutting work the upper jaw can remain in the standard 
configuration. In the standard configuration the entire “throat” of the bottom and top jaws is used. 
Measuring from faces of the top and bottom vise jaws and into the throat of the jaws- you will measure 
.142”. This throat dimension of .142” is how much of the key is consumed by the vise jaws when the key 
is clamped. Most keys are rarely cut deeper than .142” from the back edge of the key blade. 
Some padlock keys and some General Motors keys and Medeco Hi-Security keys have cuts deeper than 
.142” from the back edge of the key blade. For these keys you have two choices to clamp the keys. 
A) The old-fashion way. Use a pair of round wire shims made from Music Wire about .037” diameter
and about 1- ½” long. Place a wire shim in each vise jaw against the back edge and lay the key in front
of the shim- effectively pushing the key out of the vise jaws and clamping on the remaining .105” of
the key.
B) The“step” jaw way. Loosen the knurled knob securing the top vise jaw in place and flip the top
 jaw over the step jaw side. Retighten the knurled knob securing the top vise jaw. You must do both 
 vise jaws for this to work. 
By opening the vise jaws just enough to slide the key in you will be making the key lay right in front of the 
step portion of the top vise jaw effectively pushing the key out of the vise jaws and clamping on the 
remaining .105” of the key. See Figure 2 below.
