Euro Profile V10 Double Cylinder 35/45mm – Keyed to Differ

The V10 High Security Double Cylinder is a premium architectural locking solution engineered for doors that require maximum mechanical protection. As a Double Cylinder (Key/Key operation), it provides keyed entry and exit from both sides of the door. This configuration is particularly essential for doors with glass vision panels, as it prevents an intruder from simply breaking the glass and reaching inside to unlock the door.

The V10 High Security Double Cylinder series is defined by its sophisticated 10-pin internal mechanism, offering a significant security upgrade over standard 5 or 6-pin domestic cylinders. This high-density pin array provides a formidable barrier against sophisticated bypass techniques, providing peace of mind for both residential and commercial applications.

Technical Specifications of V10 High Security Double Cylinder

The V10 series is manufactured to exacting tolerances, ensuring smooth operation while maintaining a robust mechanical defense.

High-Security Engineering & Defensive Features

The V10 series integrates multiple layers of defense to protect against both “clean” and “destructive” entry methods:

• 10-Pin Anti-Pick Technology: By utilizing a high-density, multi-row pin configuration, the V10 High Security Double Cylinder makes manual picking and raking nearly impossible. The sheer number of pin combinations ensures a vast “key bitting” array, making it statistically improbable for a non-authorized key or picking tool to align the shear line.

• Hardened Anti-Drill Defenses: The cylinder face and internal core are reinforced with hardened steel pins and plates. These “anti-drill” zones are strategically placed to deflect drill bits and protect the internal springs and shear line from destructive bypass attempts.

• Anti-Snap Sacrificial Line: In the event of a “lock snapping” attack—one of the most common methods of forced entry—the cylinder is designed to break at a predetermined sacrificial line. This leaves the central locking cam intact and protected deep within the lock case.

• Anti-Bump Resistance: Specialized driver pins are engineered to remain stable under the kinetic impact of “bumping” techniques, ensuring the lock remains secure against vibration-based bypasses.

Primary Applications

1. Residential Entrance Doors: The ideal security upgrade for timber, composite, or uPVC front and back doors where high-level mechanical protection is a priority.

2. Glazed Vision Panels: Highly recommended for any door featuring glass panes. The requirement for a key on both sides prevents an intruder from bypassing the lock after breaking the glass.

3. Commercial Offices & Server Rooms: Provides a professional, high-security solution for internal offices and sensitive areas where access must be strictly controlled from both sides.

4. Apartment Entrances: Offers high-level individual security for multi-tenant buildings, ensuring only the authorized keyholder has access to the premises.

Professional Installation Tip: The “3mm Rule”

To ensure your V10 High Security Double Cylinder provides the maximum level of protection, it must be installed with precision to minimize vulnerability.

• Flush Mounting: For the highest security, the exterior face of the cylinder should not protrude more than 3mm from the face of the door handle or escutcheon. A protruding cylinder provides a “grip point” for tools used in snapping attacks.

• Proper Alignment: When installing the fixing screw, ensure the cylinder is perfectly centered. If the cylinder is tilted, it can cause the internal cam to bind, leading to difficulty turning the key.

• Dry Lubrication: To maintain the precision of the 10-pin system, apply a dry graphite lubricant to the keyway once a year. Avoid oil-based lubricants (like WD-40), as they attract dust and grit which can eventually clog the high-precision springs.
