A euro cylinder is the heart of a UPVC or composite door's security. It's the keyed barrel that operates the multipoint gearbox, making precise sizing essential for both safety and smooth operation.
We measure two dimensions: the A-side (external) and B-side (internal), such as 40/50 mm, which indicates the external and internal lengths.
In NW London, common fits include 35/35, 40/35, or 40/40 mm for retrofitted UPVC doors in areas like Hendon and Edgware. Thicker new-build doors in Colindale require longer cylinders, like 45/50 or 50/50 mm.
The key rule? The cylinder must sit flush, protruding no more than 3mm beyond the handle escutcheon. Anything more can be easily gripped and snapped, compromising security.
We guarantee your cylinder fits perfectly, installing a correctly-sized 3-Star anti-snap model. Our meticulous approach assures your door remains secure and operates smoothly, every single time.
In modern door security across NW London, cylinder snapping is a prevalent entry method that exploits a specific vulnerability: euro cylinders protruding beyond the escutcheon without anti-snap protection.
Attackers target these exposed cylinders, snapping them at the central screw line to manipulate the cam and gain entry. This method is particularly concerning for those with entry-grade factory cylinders on new-build composite doors in places like NW9 Colindale's Beaufort Park and Colindale Gardens.
Older, non-anti-snap cylinders on 1990s-2000s UPVC doors in Hendon, Edgware, and Kingsbury are also at risk. Insurers often flag these vulnerabilities during renewals.
The solution? A TS007 3-Star Kitemark cylinder, designed to resist snapping, bumping, picking, and drilling. These are sized to sit flush, satisfying most insurance requirements.
For higher-value properties, an SS312 Diamond Sold Secure cylinder provides additional protection. Upgrading guarantees enhanced security.

Understanding the TS007 3-Star rating is essential for anyone looking to enhance their door security. This rating guarantees us that a euro cylinder meets rigorous testing standards – protecting against snapping, bumping, and picking.
When a lock has this certification, we know it's been through a series of tough examinations to confirm it stands strong against forced entry attempts.
The 3-Star Kitemark indicates that the lock provides top-tier security features, making it an ideal choice for modern composite and UPVC doors commonly found in new-build estates like Colindale Gardens and Beaufort Park.
By choosing a 3-Star rated cylinder, we're not just following industry standards; we're actively safeguarding our homes against threats.
Let's prioritize investing in these high-security cylinders to keep our homes secure. With this rating, we're not only meeting insurance requirements but also guaranteeing security.

Choosing between keyed-alike and keyed-to-differ systems can greatly impact our convenience and security in multi-door suburban homes.
With keyed-alike systems, we can use a single key for multiple locks, simplifying our daily routines and reducing the number of keys we carry. This option enhances accessibility for families and offers a streamlined approach to managing access.
However, keyed-to-differ systems provide each door with a unique key, adding an additional layer of security. This method guarantees that if one key is lost or stolen, only one entry point is compromised. It's a preferred option for those prioritizing security over convenience.
When deciding, we should consider our lifestyle and security needs. If ease of access is our priority, keyed-alike might be ideal.
But if we're more concerned about potential security breaches, opting for keyed-to-differ could be the safer choice for our suburban homes.

We measure on-site — cylinders are sized in mm on each side of the fixing screw. Getting this right first time avoids the door not closing properly.
Keyed-alike means one key opens multiple doors on your property — useful for suburban homes with front, side and back doors. Keyed-to-differ means each door has its own key, more common for multi-let or commercial premises.
No callout fee. Fixed quote on the phone before we start.
Yes — most euro cylinder replacements are a good moment to upgrade to a TS007 3-Star anti-snap rated cylinder at the same time.
Typically 20-30 minutes per door. We carry common sizes in the van for a first-time fix.
Switching from keyed-alike versus keyed-to-differ considerations, let's tackle the practical task of euro cylinder replacement. It's a quick, clean job if we size it right.
First, we measure the existing cylinder from the center screw on each side, or check the door and handle position if it's seized. Confirm the keyway profile and decide if you want keyed-alike or keyed-to-differ.
Next, we loosen the single fixing screw on the door edge, turn the key to align the cam, and slide the old cylinder out.
Slide the new 3-Star anti-snap cylinder in, re-fit the fixing screw, and test the key turn from both sides under load with the door both open and closed.
Finally, we hand over the keys – typically three with an anti-snap cylinder – and a restricted-key card if applicable. The whole job usually takes 15-20 minutes, ensuring a clean, secure fit.
