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

Cylinder lock SYNOLOGY 35×35 mm in matte nickel finish is a mechanical door cylinder with a long profile designed to fit doors requiring a compact 35 mm by 35 mm dimension. Supplied with three keys, this cylinder is intended as a direct replacement or upgrade for residential and light commercial doors where a matching profile and key count are required. The matte nickel surface provides a neutral appearance that integrates with a variety of door hardware styles.

Advantages

The SYNOLOGY cylinder offers a standardized 35×35 mm size for straightforward replacement, and the long profile allows compatibility with doors needing extended reach. Being mechanical, it does not require power or batteries and functions reliably in standard door-locking systems. The matte nickel finish resists fingerprints and offers a low-gloss, corrosion-resistant surface suitable for indoor and sheltered outdoor use. Supplied with three keys, the product provides immediate usability and spare key access.

Suitable for

• Replacement of existing 35×35 mm cylinders in residential doors
• Light commercial doors that accept long-profile cylinders
• Interior and exterior doors with matching cylinder dimensions
• Situations requiring three identical keys for household or small office use

Key specifications

• Finish: Matte nickel
• Operation type: Mechanical cylinder lock
• Number of keys supplied: 3
• Profile: Long/extended profile suitable for compatible lock cases

How to use

Measure the existing cylinder dimensions and profile to ensure the 35×35 mm long-profile cylinder matches the door cutout before installation. Remove the screw securing the old cylinder from the edge of the door, withdraw the old cylinder, and insert the SYNOLOGY cylinder so the cam aligns correctly with the lock mechanism. Secure the cylinder with the fixing screw and verify smooth operation by turning the provided keys from both sides. If necessary, make minor adjustments to the screw position or door hardware to ensure the cylinder sits flush and operates without binding.

Usage recommendations

For longevity and reliable performance, lubricate the cylinder with a graphite or PTFE-based lock lubricant at regular intervals and avoid using oil-based sprays that can attract dirt. Keep the three supplied keys in separate, secure locations to reduce the risk of lockout; consider ordering additional keys or a keyed-alike set if multiple locks should operate with the same key.
