ABSTRACT:
A key with a very large number of code combinations. The key includes a longitudinally extending key blade with a wave-like side code pattern forming a wave-like surface including a ramp portion at a free end portion of the key blade with the wave-like guide being formed on the key blade at a side surface. A key contacting portion engages the wave-like side code pattern and is positioned by way of a specific pivotal position of the finger. A specific asymmetric displacement of the key contacting portion is formed in an asymmetric free end of the finger so that the specific pivotal displacement of the key contacting portion is available relative to the specific pivotal displacement relative to the wave-like side code pattern. The number of possible code combinations is consequently further increased.
