An auxiliary blocking element is designed for cooperating with a recess (10) that is arranged at a key shaft (3) when the key is inserted till to a maximum insertion depth. The recess is completely arranged in a groove (7) that runs in a longitudinal direction of the key shaft and moves away from a key tip (5), where the groove is formed in a broad side of the key shaft. |
