Abstract
The invention relates to a rotary cylinder lock (1) which is designed to be actuated with a multi-groove key. The inventive lock comprises: a rotor (10) which is mounted such that it can rotate inside a stator (20) and at least one spring which is mounted such that it can move inside a guide housing (41, 42, 43, 44, 45, 46) between a locked position and an unlocked position each spring being coupled to an elastic return means which moves same into the locked position. The invention is characterised in that each guide housing (41, 42, 43, 44, 45, 46) can receive two different types of springs which can co-operate respectively with each of the two key grooves which extend such as to oppose the drive force exerted by the associated elastic return means when the key is inserted into the rotor.
