Principle of Opening with Prima Decoder
This entire process is very easy – you insert the Tension tool that puts the lock carriage (lock tongue) in tension. This is the same function as the key normally does when it is turned. After that the first soft key with the pins is inserted. It’s important to emphasize that this soft key has the exact geometry and size of the original key of Yale 3×3 pins. Moreover those teeth (pins) have the possibility to move.
In brief by slightly shaking both the Tension and the Stick with pins the vibrations move the pins of the soft key with pins . This happens until it “assumes” the position corresponding to that of the “teeth” of the original key. In this way the profile of a half of the key is obtained. To obtain the other half, it is necessary to repeat the operation for the second half of the profile with the second soft key. At this point you have a complete double bit profile able to open and close the lock exactly like the original key of Yale 3×3 levers.
