Cylinder lock SYNOLOGY 35×40 mm, matte nickel, long profile, 3 keys

Euro-profile cylinder lock SYNOLOGY 35×40 mm in matte nickel finish, designed as a long-profile replacement or new installation for compatible door locks. The lock comes with three identical keys and offers standard mechanical security for residential and light commercial entrances where a long cylinder dimension is required. The matte nickel surface provides a neutral appearance that blends with common door hardware.

Advantages

The cylinder lock features a long-profile design with asymmetric dimensions 35×40 mm to fit doors that require extended length on one side. The matte nickel plating resists corrosion and reduces visible fingerprints compared with polished finishes. Supplied with three keys, the lock enables immediate use and spare-key storage. The mechanism is designed for straightforward installation in standard euro-profile lock cases and supports common maintenance and rekeying procedures.

Suitable for

• Replacement of worn or damaged euro-profile cylinders in residential doors
• Installation in apartment and house entry doors requiring a long-profile cylinder
• Light commercial entrances where a standard mechanical cylinder with three keys is acceptable
• Doors with asymmetric thickness or requirements for extended cylinder length on one side

Key specifications

• Profile type: Euro-profile (long)
• Dimensions: 35 mm on one side × 40 mm on the other side
• Finish: Matte nickel
• Included items: Three identical keys
• Intended use: Mechanical cylinder for door lock systems

How to use

Measure the existing cylinder from end to center of the fixing screw and to the opposite end to confirm the 35×40 mm dimensions before installation. Turn off any electronic or alarm integrations connected to the door hardware if present. Remove the old cylinder by unscrewing the retaining screw and extracting the cylinder while holding the key in a neutral position as required. Insert the new SYNOLOGY cylinder until the cam aligns with the lock case, secure it with the retaining screw and verify smooth operation by turning the supplied key and checking latch or bolt movement.

Usage recommendations

For reliable operation, lubricate the cylinder periodically with a dry graphite or PTFE-based lubricant and avoid oil-based sprays. Keep spare keys in a safe place and consider using a master-key or keyed-alike system if multiple doors require the same key. When fitting to external doors, ensure compatibility with weatherproof escutcheons and appropriate door furniture to maintain security and weather resistance.
