Cylinder lock SYNOLOGY 30×40 mm, matte nickel, long profile, 3 keys

Cylinder lock SYNOLOGY 30×40 mm in matte nickel is a long-profile keyed cylinder designed for doors that require asymmetric dimensions. The lock comes with three identical keys and fits into door locks accepting a 30×40 mm profile. Its matte nickel finish provides a neutral appearance that integrates with a variety of door hardware styles while offering the mechanical function required for controlled access in residential and light commercial environments.

Advantages

The long-profile design accommodates doors with thicker or uneven frames and provides reliable engagement with standard locking mechanisms. Supplied with three keys, the cylinder enables multiple users to access the door without additional key duplication at the time of installation. The matte nickel surface resists visible fingerprints and blends well with contemporary hardware finishes, while the precision-machined components ensure smooth key action and a consistent locking experience.

Suitable for

• Residential exterior and interior doors requiring a long-profile cylinder
• Light commercial doors in offices, small shops or service areas
• Replacement of existing 30×40 mm cylinders
• Doors with asymmetric or thicker door profiles where a 30×40 mm size is specified

How to use

Install the cylinder into a compatible lock case or door escutcheon designed for a 30×40 mm long-profile cylinder. Ensure the cylinder is aligned with the internal cam and fixing screw hole, then secure it in place with the retaining screw. Test the supplied keys to confirm smooth insertion, rotation and engagement of the locking mechanism before regular use. For replacement, remove the old cylinder by loosening the retaining screw and withdraw it from the door, then insert the new SYNOLOGY cylinder following the same alignment and securing steps.

Usage recommendations

For reliable operation, periodically lubricate the cylinder with a graphite-based lock lubricant and avoid using oil-based sprays that can attract dust. Confirm door thickness and existing lock-case compatibility with the 30×40 mm long profile prior to purchase to ensure correct fit. Keep spare keys stored securely and consider professional installation if the door has nonstandard fittings or if precise alignment is required.
