100mm- side replacement cylinder

Product Description

The 100mm side replacement cylinder is a high-security euro profile lock cylinder. It is designed to replace worn, broken, or low-security cylinders in residential and commercial doors.

This cylinder measures 100mm in total overall length. This makes it compatible with a wide range of door thicknesses and lock cases commonly found throughout Europe and beyond.

Crafted from solid brass or stainless steel, this replacement cylinder provides robust protection against forced entry attempts. It also restores smooth operation to your door.

Whether upgrading from a basic cylinder or renovating your home’s entrance, this cylinder delivers peace of mind with advanced security features and professional-grade construction.

What Does 100mm Mean for a Replacement Cylinder?

Understanding the 100mm measurement is crucial for selecting the correct replacement cylinder. The 100mm refers to the total overall length of the lock cylinder from one end to the other.

This cylinder is typically configured with two sections, one for each side of the door. A common split for a 100mm euro cylinder is 45mm on the exterior side and 55mm on the interior side. Other splits are available depending on your door thickness.

To ensure proper fitment, measure your existing cylinder from the center of the fixing screw hole to each end. Alternatively, measure the overall length and verify compatibility with your door’s lock case.

What Security Features Does This Cylinder Include?

The 100mm side replacement cylinder is engineered with multiple security features. These deter common break-in methods.

Advanced anti-pick pins, often including mushroom or spool pins, make lock manipulation extremely difficult. Anti-drill hardened steel pins or plates protect the cylinder core from drill attacks.

Anti-bump technology prevents lock bumping, a technique where a specially cut key is used to force the lock open. Many models also feature an anti-snap design with a predefined breaking point. This ensures that even if attacked, the cylinder breaks safely without exposing the locking mechanism.

These combined features make this cylinder suitable for front doors, apartment entrances, and commercial applications.

What Materials and Finishes Are Available?

The 100mm side replacement cylinder is available in several premium materials and finishes to match your door hardware.

Solid brass construction offers excellent strength, natural corrosion resistance, and a classic appearance that ages gracefully. Stainless steel options provide superior durability and a modern, sleek look that resists tarnishing in harsh environments.

Available finishes include satin nickel for a brushed, contemporary look. Polished chrome offers high-gloss elegance. Matt brass provides a traditional warm tone. Matte black makes a bold modern statement.

Some premium models feature a fume finish or Hamilton gold finish for distinctive aesthetic appeal. All finishes are applied with corrosion-resistant coatings to ensure long-lasting appearance.

How Do You Install a 100mm Side Replacement Cylinder?

Installation is straightforward and can typically be completed in under 10 minutes with a screwdriver.

First, open the door and locate the fixing screw on the edge of the door. It is usually positioned inline with the cylinder.

Second, loosen the fixing screw. Do not remove it completely unless necessary.

Third, insert the key into the existing cylinder and turn it slightly to align the cam.

Fourth, pull the old cylinder out from the opposite side of the door.

Fifth, insert the new cylinder. Ensure the cam is aligned correctly with the lock mechanism.

Sixth, tighten the fixing screw securely but not excessively.

Finally, test the cylinder operation with the supplied keys before closing the door.

Most cylinders come with three keys. This provides a spare for household members or emergencies.

What Is the Difference Between Single and Double Cylinder Versions?

The 100mm side replacement cylinder is available in two primary configurations.

A double cylinder requires a key to lock or unlock the door from both interior and exterior sides. This offers maximum security for doors with glass panels where an intruder could otherwise reach through and turn a thumbturn.

A thumbturn cylinder features a key on the exterior side and a twist knob on the interior side. This allows quick egress without a key in emergencies.

Choose the configuration that best suits your security needs and local building codes regarding emergency exit requirements.

What Standards and Certifications Should You Look For?

Quality cylinders meet rigorous European security standards.

Look for cylinders certified to DIN EN 1303, the European standard for building hardware cylinders. This tests for durability, corrosion resistance, and security.

ISO 9001:2015 certification indicates the manufacturer follows quality management system standards. Some models feature SKG certification or are tested to withstand over 200 hours of salt spray for corrosion resistance. This makes them suitable for coastal or high-humidity environments.

Why Choose a 100mm Side Replacement Cylinder for Your Door?

The 100mm size is one of the most common euro cylinder lengths. This makes it compatible with a vast range of door lock cases.

Upgrading to a high-security cylinder significantly improves your door’s resistance to forced entry. This does not require door modifications.

The simple DIY installation means you can enhance your home security immediately. The included keys and clear instructions make the process accessible to any homeowner.
