Keying a BiLevel cylinder alike to a Medeco³ cylinder is a snap. As mentioned before, you must start with a key code with all aft position cuts that is specifically created to support BiLevel. (Both individual codes and master key systems for BiLevel are available from the Medeco factory.) The key code will contain both numbers (cut depths) and letters (cut angles). The cut depth numbers are all that are necessary to choose the correct BiLevel pins. For example, if your key cut is a 2M, you would choose a #2 bottom pin. Top pins are numbered so that they correspond with the bottom pin numbers – a #2 bottom pin gets a #2 top pin.
Master keying BiLevel is also quite easy. For example, if your master key is cut to a 2M and your change key is a 4M, select a #2 bottom pin, add a #2 wafer, and top it off with a #4 top pin.
A pin kit is available that contains 100 of each of the bottom, master and top pins, plus set screws and springs. The pin kit part number is KJ1501.
Please contact your Medeco distributor for pricing and availability.
