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 — and it takes only seconds. Homes across Bexleyheath, from the terraced streets off Watling Street to the newer builds near the Broadway, are protected by exactly the type of budget euro cylinder that snap attacks exploit. 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 homeowner or tenant can make to a front or back door.

Frequently asked questions
What is a TS007 3-star cylinder and do I actually need one on my Bexleyheath front door?
TS007 is the British Standard rating scheme for euro cylinder security. A 3-star cylinder achieves the highest rating by combining anti-snap, anti-pick, anti-drill and anti-bump resistance in one barrel. Whether you need one depends on your current cylinder. If your uPVC or composite door has a standard cylinder that protrudes more than a few millimetres beyond the door face, it is at meaningful risk from a snap attack. Many insurers are now asking about cylinder ratings at claim stage, so fitting a 3-star cylinder can also affect your home insurance position. We can assess your existing cylinder when we arrive and advise you on the spot.
How do I know if my euro cylinder is the right size for a replacement?
Euro cylinders are measured in millimetres from the centre of the fixing screw to each end — written as, for example, 35/45mm. The measurement is taken with the cylinder in place, from the outside face of the door to the centre of the fixing hole, and from the centre of the fixing hole to the inside face. Getting this wrong by even five millimetres can leave the cylinder protruding and vulnerable, or sitting too far recessed to operate smoothly. Our technicians measure on-site and carry a range of sizes to ensure the replacement fits correctly within the door.
Can a locksmith open my door without damaging it if I am locked out in Bexleyheath?
In most cases, yes. A skilled locksmith will attempt non-destructive entry first — using specialist tools to manipulate the lock mechanism so the door opens without damage. Whether this is possible depends on the type of lock, the condition of the cylinder and the door construction. If a previous snap attack has already damaged the cylinder, non-destructive entry may not be an option and controlled drilling may be necessary. We always explain what is involved before we begin and work to minimise any impact on your door. We also carry replacement cylinders so we can re-secure the door immediately after gaining entry. The first step if you are locked out should be to check for a spare key with a trusted neighbour or family member, or whether a rear or side entrance is accessible — but if none of those options are available, call 020 3757 5689.
How much does it cost to have an anti-snap euro cylinder fitted?
We do not quote figures in advance of knowing the specifics of your door, because the final price depends on a number of factors: the size of cylinder required, the grade and specification of the replacement barrel, whether any additional work is needed such as adjusting the keep or replacing a worn cam, the time of day, and the travel distance to your address. What we do commit to is confirming an exact price on the phone before we send anyone out, so you are never surprised. Call 020 3757 5689 and we will work through the details with you and give you a clear figure straight away.
My uPVC door handle has dropped and the door will not lock properly — is that a cylinder problem or something else?
A dropped handle or a door that will not lock from the outside is almost always a multipoint gearbox fault rather than a cylinder issue. The gearbox is the central mechanism inside the door edge that drives the hooks, rollers and bolts up and down when you lift the handle. When the internal springs or cams in the gearbox fail, the handle loses its return and the locking points stop engaging. This is a very common repair call for uPVC door lock repair in Bexleyheath. Our mobile locksmiths carry a range of replacement gearboxes and can usually complete the repair on the same visit, restoring full multipoint locking.
Does a lock change Bexleyheath service cover mortice deadlocks, or just euro cylinders?
Our lock change Bexleyheath service covers all common residential lock types — euro cylinders in uPVC and composite doors, 5-lever mortice deadlocks and sash locks in timber doors, and Yale-type nightlatches with rim cylinders. If your 5-lever mortice deadlock is old, stiff or no longer meets the BS3621 standard your insurer requires, we can replace the entire mechanism with a new one that meets current specifications. For nightlatches, we can often upgrade just the rim cylinder to a higher-security version without changing the body. We will always advise on which approach makes the most sense for your specific door and lock before any work begins.
