Euro Profile V10 Single Cylinder 42mm – Keyed Alike (KA31)

V10 Single Cylinder KA31 is the professional’s benchmark for one-sided, high-security access control. In the world of architectural ironmongery, the V10 series is synonymous with precision engineering, designed to offer a superior defense against sophisticated bypass techniques while providing the convenience of a Keyed Alike (KA31) configuration for multi-point commercial and industrial environments.

By integrating a dual-row, 10-pin system into a compact “Half Cylinder” format (typically a 32/10 asymmetric split), the V10 Single Cylinder KA31 provides a tamper-proof “blind” internal face and a highly complex internal architecture that allows for thousands of secure key combinations under a single, unified key code.

The “V10” system is defined by its internal 10-pin dual-row mechanism. This high pin count is a critical requirement for high-security applications, as it provides the mathematical complexity necessary to maintain a Grade 6 security rating even when cylinders are configured to operate on the same KA31 key.

Key Performance Benefits

• Keyed Alike Convenience (KA31): This specific code allows multiple cylinders—across different doors, gates, or shutters—to be operated by the same physical key. This “One-Key” solution is essential for facility managers who need to reduce key clutter while maintaining strict perimeter security.

• Pick & Bump Immunity: The dual-row configuration of hardened steel pins creates a significantly more complex shear line. This makes the V10 virtually immune to traditional picking and kinetic “bumping” techniques often used to exploit standard 5 or 6-pin locks.

• Restricted Key Control: V10 cylinders are supplied with a unique security code card. This ensures that duplicate keys cannot be cut at a high-street locksmith without proof of authorization, giving property owners total control over who possesses a key to the premises.

• Hardened Drill Defense: The cylinder face is reinforced with high-density hardened steel pins and a ceramic internal plate. This system is designed to shatter or dull high-speed drill bits, protecting the pin stacks from destructive entry.

Precision Sizing: The 32/10 Asymmetric Split

A 42mm single cylinder is measured from the center of the fixing screw to each end. In this configuration, the 32mm external reach is optimized for modern building materials that require a flush, secure fit.

Architectural Tip: The 32mm external offset is specifically tailored for slimline aluminum shopfronts and narrow-profile commercial doors. It ensures the cylinder sits flush with the handle escutcheon, eliminating the “shoulder” protrusion that burglars use to grip and snap a lock.

Installation Pro-Tip: The “8-Position” Universal Cam

One of the most valuable features of the V10 Single Cylinder KA31 is its adjustable cam. Because different brands of garage door locks and shutter mechanisms require the internal actuator (the cam) to sit at different starting angles, the V10 is designed for universal compatibility.

1. Locate the small spring-loaded pin on the side of the cylinder body.

2. Depress the pin and manually rotate the cam to the desired angle (typically 30° or 45°).

3. Release the pin to lock the cam into position. This ensures that the key can be inserted and turned without the cam “binding” against the internal stops of the lock case.

Simplify access management with the V10 Single Cylinder KA31, designed for smooth operation and convenient keying. This cylinder allows multiple locks to be operated by the same key, reducing the need for multiple keys while maintaining secure locking for doors. The 42mm Euro profile ensures a precise and secure fit for standard doors, making it ideal for residential, commercial, and multi-unit properties.

Constructed from premium materials, the V10 Single Cylinder KA31 offers excellent resistance to tampering, forced entry, and daily wear, ensuring long-term durability. Its keyed alike system simplifies access without compromising security, making it perfect for homes, offices, and properties with multiple doors. Easy to install and designed for consistent use, this V10 Single Cylinder KA31 combines strength, convenience, and reliable protection.
