The cylinder includes a plurality of bottom passages, wherein the bottom pin is movably mounted, and the cylindrical housing includes a plurality of top passages, wherein the top pins are movably mounted, and the bottom passages are rotatably aligned by the cylinder The top channel, and the bottom channel and the top channel are both perpendicular to a cylinder axis. The bottom pin is designed to act with a key tip that is inserted into the keyhole, and a spring element is provided in each of the top passages to bias the top pin in the direction of the bottom pin. The cylinder lock additionally includes a closure member that is releasably secured to the cylindrical housing and that shields the top passage from the outward opening of the cylinder to provide spring element blocking.

A cylinder lock as described above is found in EP 0 403 551 B1. The cylinder lock described in the present specification comprises a cylindrical casing having a cylindrical hole in which a cylinder is pivoted, and a key is inserted into the cylinder by a hand to rotate the cylinder. The key tip of the key can be used with a number of active pins, each pin having a different length. When the tip of the cylinder corresponds to the length of the pin, the cylinder is rotatable in the bore of the cylinder. The pinning activities are installed in the passage of the cylinder and the cylindrical casing. Each pin is subjected to a spring preload to press the pin against the key tip. The passage in the cylindrical housing contains an opening outwardly from the cylinder, and the pin and spring element can be inserted into the passageway through the opening. After the pin and spring element are inserted, the channel must be covered by a cover element, and each channel includes a separate plug that is pressed into the channel opening. The plug that is pressed into the passage opening is designed as a cylindrical plug which is pressed into the passage via a tight fit. After the plug is pressed into the channel, the plug in the channel can no longer be removed.
