The invention relates to a luminescent display method for locating a lock system in reduced-visibility environments, characterised in that the contour of the groove of a lock (1) is rendered visible in the dark owing to photoluminescent luminous irradiation, whereby the lock groove can be differentiated from the surrounding auxiliary elements by means of illumination. The device is characterised in that the key or opening element can be inserted under poor lighting conditions. The invention is characterised in that the light produced during use is independent of any power supply.
