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 Fulham is no exception. Streets such as Munster Road and the dense blocks of flats along the New King's Road see a steady stream of break-in attempts that exploit cheap, unrated cylinders. A skilled burglar can snap a standard euro cylinder in under a minute using nothing more than a screwdriver and a pair of pliers, then turn the remaining stub with a flat-head tool and walk straight through your front door. Upgrading to a TS007 3-star anti-snap euro cylinder closes that vulnerability entirely, and it is one of the most cost-effective security improvements any Fulham homeowner or tenant can make.

Why Standard Euro Cylinders Fail — and What Anti-Snap Locks Do Differently

A standard euro cylinder is shaped so that the section protruding beyond the door face is under enormous stress when a burglar applies sideways force. That exposed section simply shears off, exposing the internal cam that controls the latch. TS007 3-star anti-snap cylinders address this with a deliberate sacrificial break point engineered into the front of the cylinder — well away from the locking mechanism itself. When force is applied, the front portion breaks off as designed, but the internal workings remain fully intact and locked. The cylinder cannot be turned, and the door stays shut. Many also incorporate anti-pick, anti-drill, and anti-bump features, so they resist the full toolkit a modern opportunist carries.

The TS007 standard is set by the British Standards Institution and is the benchmark most home insurers and local authority housing associations now expect. A 3-star rating can be achieved by fitting a single 3-star cylinder, or by combining a 1-star cylinder with a 2-star door handle — our technicians will advise which combination suits your existing door furniture so you are not paying for parts you do not need. If you are a tenant, we can also liaise with your letting agent about what is permissible under your tenancy agreement before we start work.

Upgrading Euro Cylinders and Anti-Snap Locks on uPVC and Composite Doors London-Wide

The vast majority of uPVC and composite front doors fitted across Fulham — and across London more broadly — use a multipoint locking mechanism driven by a euro cylinder. Getting the cylinder size exactly right is critical: a cylinder that protrudes too far is easier to snap, while one that is too short can prevent the cam from engaging the multipoint hooks properly. Our technicians measure the existing cylinder before sourcing a replacement, noting the distance from the centre screw to each end (expressed as two figures, for example 35/45mm), so the new TS007 3-star unit fits flush or just within the 3mm tolerance that anti-snap standards require.

During the fitting appointment we also inspect the door alignment, the condition of the multipoint lock body, and the keep plates on the frame — because a high-quality cylinder fitted in a poorly aligned door still represents a weak point. Where we find minor issues such as a misaligned latch or a worn keep, we address them at the same visit where possible. We work damage-free wherever the door condition allows, using the existing fixing screw hole so there is no cosmetic damage to the door panel. For landlords managing several Fulham properties or a block of flats, we can schedule multiple cylinders in a single visit to minimise disruption to tenants.

Door Lock Replacement London: When a Full Lock Change Makes More Sense

Sometimes a cylinder swap is not the right answer. If your existing euro cylinder is a cheap, unbranded unit that has been in place for many years, or if the multipoint lock body itself is worn, stiff, or showing signs of attempted forced entry, a fuller door lock replacement London residents often overlook may be the more sensible route. We carry multipoint lock cases that are compatible with the most common uPVC door profiles, and fitting a new lock body alongside a 3-star cylinder means every component is working as a system rather than a patchwork of old and new parts.

A full lock change is also advisable after a break-in attempt, after moving into a new flat or house (you have no way of knowing how many keys are in circulation from the previous occupant), or after losing a set of keys. Our 24-hour locksmith London service means you do not have to wait until Monday morning to sort this — call us at any point, day or night, and we send a technician straight away. We are usually with you in about 30 minutes, though we will always give you a realistic arrival window based on where in Fulham or the surrounding area we are starting from.

What Determines the Cost — and How We Quote

We do not publish fixed price tables because the right quote depends on several honest variables: the size and specification of the cylinder your door requires, whether a multipoint lock body or additional hardware also needs replacing, the time of day or night (evenings, weekends, and bank holidays affect our call-out charge), and travel distance if you are on the outer edge of our coverage area. What we can promise is that we confirm an exact, agreed price with you on the phone before anyone gets in the van — there are no surprise additions when we arrive on site. If the job turns out to be more complex than described, we explain why and get your approval before proceeding.

If you are a homeowner on a street like Hurlingham Road or a tenant in one of the mansion conversions near Eel Brook Common, the fastest way to get an accurate figure is simply to call us on 020 7871 7823. We will ask a few quick questions about your door type, the cylinder size if you know it, and your postcode district, and we will give you a clear quote straight away. We answer every call 24/7 — there is no voicemail, no call centre, and no waiting until office hours.

Frequently asked questions

Answers to what our customers ask most. Still unsure? Just call.

How do I know if my front door already has an anti-snap cylinder fitted?+

The clearest sign is a TS007 or 3-star rating mark, which is usually stamped or printed on the cylinder body itself or noted on the packaging if the previous occupant kept it. Visually, many anti-snap cylinders have a slightly different profile near the front face — a scored or chamfered groove that marks the engineered break point — but this is not always obvious to the untrained eye. If you are unsure, the safest approach is to call us on 020 7871 7823 and describe your door. We can often tell from a photo sent to our number, or we can visit, check the cylinder, and advise you on the spot without any obligation to proceed immediately.

My door is uPVC — does that change which anti-snap cylinder I need?+

Yes, it matters quite a lot. uPVC doors use euro cylinders to drive a multipoint lock, and those cylinders come in a wide range of sizes depending on the door slab thickness and the position of the fixing screw. The wrong size — even by 5mm — can leave the cylinder proud of the door face, which is precisely the exposure a burglar targets when snapping. Our technicians measure your existing cylinder before sourcing a replacement TS007 3-star unit, ensuring the new cylinder sits at or within the door face. We also check that the cam profile matches your multipoint lock body so every hook and bolt engages correctly after the swap.

Can a tenant arrange a cylinder upgrade, or does the landlord have to authorise it?+

This depends on your tenancy agreement and, in some cases, whether the property is managed by a letting agent or a housing association. Generally, tenants are not permitted to change locks without the landlord's consent, as doing so could be considered a breach of contract and may leave you liable for any re-entry costs if you later lock yourself out and cannot provide a key to the landlord. We recommend speaking to your landlord or letting agent first — many are very willing to agree once they understand that an anti-snap upgrade reduces the risk of a break-in and the associated liability. If consent is given, we are happy to fit the new cylinder and provide duplicate keys for all parties as agreed.

What is the TS007 3-star standard and is it a legal requirement?+

TS007 is a British Standard specification published by the BSI that sets out performance requirements for cylinder locks against specific attack methods — including snapping, picking, drilling, and bumping. A 3-star rating means the cylinder has passed the highest level of testing under that standard. It is not a legal requirement in most residential settings, but it is increasingly written into home insurance policies as a condition of cover for uPVC and composite doors — particularly in London boroughs where burglary rates are higher. Some local authority and housing association tenancy agreements also specify it. Fitting a TS007 3-star cylinder is good practice regardless of whether your insurer currently requires it.

How quickly can you get to me in Fulham if I need an emergency lock change?+

We operate a 24/7 mobile service and cover Fulham and the surrounding areas continuously — including late evenings, overnight, weekends, and bank holidays. When you call 020 7871 7823 we despatch a technician straight away and are typically with you in around 30 minutes, though we will always give you an honest arrival window on the phone based on where we are coming from at that moment. We do not leave calls to go to voicemail at night, and there is no separate out-of-hours number to find — the same line is answered around the clock.

What factors affect how much an anti-snap cylinder upgrade costs?+

Several honest factors feed into the final quote: the size and specification of the cylinder your door needs (some require longer or thicker cylinders that cost more to manufacture to TS007 standard), whether the existing multipoint lock body or keep plates also need attention, the time of day (evenings, weekends, and bank holidays carry a higher call-out charge than standard daytime hours), and travel distance if you are at the edge of our service area. We always confirm an exact agreed price with you on the phone before we set off — nothing is added on arrival. The quickest way to get a clear figure is to call us on 020 7871 7823 and describe your door and location.
