Euro Cylinders & Anti-Snap Locks
Lock snapping has become one of the most common methods burglars use to defeat standard euro cylinders on uPVC and composite doors across London — and Lewisham is no exception. Streets around Catford, Brockley and the Lee Green area have all seen break-ins where the lock was snapped rather than picked, often in under a minute and without making much noise. If your front door has a euro cylinder that was fitted as standard when the door was installed, the chances are it offers little resistance to this technique, and upgrading it is one of the most cost-effective security improvements you can make.

Frequently asked questions
How do I know if my current euro cylinder is vulnerable to snapping?
The easiest indicator is how much of the cylinder protrudes beyond the face of the door handle or escutcheon plate. If more than 3mm of the cylinder is exposed on the outside, it is in the higher-risk category. Standard cylinders sold with most uPVC doors in the UK do not have an anti-snap feature, so unless yours is specifically marked as TS007 3-star or anti-snap, it is safest to assume it needs upgrading. Our technicians can assess this for you on arrival and show you exactly what they find before recommending anything.
Will upgrading to an anti-snap cylinder affect my home insurance?
Many UK insurers ask about the standard of locks fitted to your front door, and some policies specify that door locks should meet a recognised British Standard. Fitting a TS007 3-star anti-snap euro cylinder is widely recognised as meeting or exceeding those requirements. It is always worth checking the specific wording of your policy, but in our experience customers who upgrade their cylinders are better placed when they contact their insurer. We do not liaise with insurers on your behalf, but we can confirm in writing what has been fitted if you need that for your records.
Can you replace a euro cylinder on a uPVC door without damaging the door?
Yes, in almost all cases. Removing and replacing a euro cylinder on a uPVC or composite door is a standard, non-destructive procedure. The handle is unscrewed, the retaining screw in the edge of the door is removed, and the cylinder slides out. Provided the door and frame are in good condition, the new cylinder goes in the same way. Damage only occurs when a cylinder has already been attacked and the internal mechanism is compromised — in that situation we assess what is needed and explain clearly before proceeding.
How much does it cost to upgrade to an anti-snap lock?
We do not publish fixed prices because the final quote depends on a few variables: the cylinder size and specification needed for your specific door, the time of day you call (evenings, weekends and bank holidays may affect the call-out element), your location within the Lewisham area, and whether any additional parts such as an upgraded escutcheon plate are required. What we can tell you is that you will receive a confirmed, all-inclusive price before we begin any work — there is nothing added at the door.
I live in a flat with a communal entrance — do I need to upgrade both the communal door and my own front door?
Ideally, yes — but the two serve different security functions and the decisions may involve different parties. The communal entrance lock is usually the responsibility of the freeholder, landlord or managing agent, so changes there would need to go through them. Your own flat front door is typically your responsibility (subject to your tenancy or lease terms), and fitting an anti-snap euro cylinder to it adds a meaningful independent layer of security regardless of what is on the communal door. We work regularly with landlords and letting agents in Lewisham and can advise on the most practical approach for your situation.

When you call 020 3757 5731 you will speak to a real person, not an answering service, and we will arrange to send a technician to you straight away. We are usually on site in around 30 minutes, though travel time can vary depending on where you are and what is happening on the roads at that time of day.
