Locking system

A locking system having a key and a lock cylinder is proposed. The lock cylinder has a lock cylinder which is supported in the housing and has a key hole for inserting a key. A plurality of tumblers actuable by the key and an additional blocking member movably are disposed in the guide passage of the lock bob protrudes into the key hole, the additional blocking member being tiltable or transversal to the insertion direction of the key. The additional blocking member is arranged to cooperate with the opposite member provided to the key blade in the case where the key is introduced to the maximum insertion depth. In this respect, the opposite member is provided in a recess or recess starting from the end of the key and extending in the longitudinal direction of the key blade. 提出了种具有钥匙和锁芯的锁定系统。锁芯具有锁胆，锁胆被支承在壳体中并具有用于插入钥匙的钥匙孔。可由钥匙致动的多个制动栓和可移动地设置在锁胆的引导通道中的附加阻挡件突出到钥匙孔中，所述附加阻挡件可倾斜于或横向于钥匙的插入方向移位。附加阻挡件被设置成在钥匙被引入到达最大插入深度的情况下与设置于钥匙片的相对件协作。在此方面，相对件被设置在从钥匙末端起始并在钥匙片的纵向上延伸的凹槽或凹部中。
