Cylinder lock SYNOLOGY 30×50 mm matte nickel, long, 3 keys

The SYNOLOGY Cylinder Lock 30×50 mm in matte nickel is a long-profile euro cylinder designed for door security where extended length is required. Supplied with three keys, this lock cylinder fits doors that need a 30 mm inner and 50 mm outer length and offers a neutral matte nickel finish that blends with modern hardware. It is suitable for replacing or upgrading standard euro-profile cylinders in residential and light commercial doors, providing key access from one or both sides depending on the door setup.

Advantages

This cylinder lock combines a long-profile design with a durable matte nickel surface that resists fingerprints and complements a wide range of door furniture. The package includes three keys to provide immediate use and spare access. The cylinder’s dimensions support correct fitting in extended or asymmetric doors, reducing the need for additional modifications. Its euro-profile shape makes it compatible with common locking mechanisms and multipoint systems that accept standard cylinders.

• Replacement of worn or damaged euro-profile cylinders in residential doors

How to use

Measure the existing cylinder or the door thickness to confirm the 30×50 mm configuration before installation. Remove the existing cylinder by unscrewing the retaining screw from the edge of the door and extracting the old cylinder with the key turned slightly if necessary. Insert the SYNOLOGY long euro cylinder into the lock case, align it so the cam engages properly, and secure it with the retaining screw. Test the keys from both sides (if applicable) to ensure smooth operation and correct alignment of the cam and bolt.

Usage recommendations

For reliable operation, keep the cylinder and keyway clean and periodically lubricate with a graphite or silicone-based lock lubricant. Confirm that the cylinder length matches door and escutcheon measurements to avoid overhanging or insufficient engagement. If the door has a multipoint lock or additional security fittings, verify mechanical compatibility before replacement.
