Cylinder Lock SYNOLOGY LOCK CYLINDER D6 30x30 mm Nickel, keyed mechanical lock for Synology enclosures

SYNOLOGY LOCK CYLINDER D6 30x30 mm Nickel is a cylinder-style mechanical lock designed to provide keyed physical security for Synology enclosures and compatible NAS chassis. With a symmetric 30x30 mm profile and nickel finish, the lock replaces or upgrades existing cylinder locks used on drive bays, front panels, or removable chassis covers. It is intended for installations where controlled physical access to internal storage is required, such as small office or home NAS deployments.

Advantages

The cylinder lock offers a simple mechanical solution to prevent unauthorized opening of drive trays or chassis doors without relying on electronic measures. Its 30x30 mm form factor fits standard cylinder openings used on many Synology models and compatible equipment, while the nickel finish provides corrosion resistance and a neutral appearance that matches metal enclosures. As a keyed lock, it enables access control through physical keys, allowing administrators to grant or revoke physical access independently of software credentials.

Suitable for

• Securing drive bays and front panels of Synology NAS enclosures
• Replacing worn or damaged cylinder locks on compatible chassis
• Protecting internal storage devices in small office or home environments
• Use in racks or cabinets where a mechanical keyed lock is preferred

Key specifications

• Lock type: cylinder, keyed mechanical
• Dimensions: 30 x 30 mm profile
• Finish: nickel
• Intended mounting: front panel or drive bay cylinder opening
• Compatibility: designed for Synology enclosures and compatible chassis

How to use

Install the cylinder lock by removing the existing lock or opening the target panel, inserting the cylinder into the matching 30x30 mm opening, and securing it according to the enclosure manufacturer’s instructions (typically with a retaining clip or nut). Use the supplied keys to lock and unlock the cylinder; ensure the cylinder is fully seated and the retaining hardware is tightened to prevent rotation. Test the lock operation before returning the NAS to normal service to confirm correct fit and key function.

Usage recommendations

For reliable security, match the lock profile to the enclosure’s cylinder opening and keep spare keys in a secure location. Periodically inspect the lock for signs of wear or corrosion and lubricate the cylinder with a graphite or manufacturer-recommended lubricant if operation becomes stiff. Do not rely solely on mechanical locking for comprehensive data protection—combine with access control, backups, and encryption as appropriate.
