<p>A high security lock and key system with an increased number of code combinations is disclosed. The blade of the key has a wave-like guiding surface (104) at the side of the key blade which, upon insertion into an associated lock having a rotatable key plug, engages with one or more side locking tumblers (206) in the lock cooperating with a side locking mechanism for locking the key plug against rotation. The key blade has an extra code level (121) located at a longitudinally extending shelf surface, viz. at the upper boundary of the side material region where the wave-like guiding surface is cut at the side of the key blade.</p> |
