Lock Change After a Break-In

Once a lock has been forced, picked, or simply damaged during an attempted entry, it cannot reliably be re-secured by pushing the door shut. Even if the door appears closed, the cylinder may be bent, the multipoint mechanism may have shifted, or the frame may have been stressed in ways that are not immediately obvious. Any lock that has been attacked — even unsuccessfully — should be treated as compromised. Waiting until a convenient weekday appointment means leaving the property on a compromised latch overnight, which insurers frequently flag as a failure to take reasonable precautions. Our emergency lock change service exists precisely for this scenario: we come to you, assess the damage on the spot, and carry out the work immediately.

Wandsworth has a healthy mix of Victorian terraces with original timber frames, converted flats in older mansion blocks, and newer uPVC-door properties. Each type presents different vulnerabilities after a forced entry. A Victorian front door may have a Yale-type nightlatch and a 5-lever mortice deadlock, both of which may need attention. A uPVC or composite door relies on a euro cylinder inside a multipoint locking mechanism — and cylinder snapping is one of the most common attack methods used in South West London. Our technicians carry anti-snap, anti-drill, anti-pick cylinders rated to TS007 3-star as standard stock, so the replacement fitted that same evening is more resistant than many originals.

Not every break-in results in every lock needing a full replacement. Sometimes a cylinder has been snapped but the multipoint mechanism itself is undamaged; sometimes the reverse is true. Our approach is to assess before we quote, never the other way around. The factors that determine the final price are straightforward: the type and number of locks being replaced, the parts required (a TS007 3-star anti-snap euro cylinder costs more than a standard one because it is a materially better product), the time of day or night, and the travel distance within our Wandsworth service area. We confirm the exact figure on the phone before we set off and again on arrival before we start work — there are no surprises added to the bill once the job is done.

If your insurer requires evidence for a claim, we can outline the work carried out and the specification of the locks fitted. Many home insurance policies ask that front doors carry a BS3621-compliant deadlock, and after a break-in is often the first time homeowners discover their existing locks did not actually meet that standard. We will tell you clearly whether what we fit satisfies the most common insurer requirements — not as a legal guarantee, but as a straightforward, factual assessment based on the product specifications. For anyone managing a commercial property in Wandsworth — a shop unit, an office above a parade, a warehouse or storage facility — a commercial lock change follows the same same-day process, and we carry hardware suitable for heavier-duty commercial door furniture as well.

The lock types most commonly involved in Wandsworth break-ins fall into three broad categories, and understanding which you have helps you have a more informed conversation when you call. First: euro cylinders in uPVC and composite doors. These are the dominant lock type on properties built or refurbished from the 1990s onwards, and they are the target of snapping attacks — a technique where force applied to the outer section shears the cylinder and exposes the cam that operates the lock. Replacing a snapped cylinder with another standard cylinder solves nothing. We fit anti-snap cylinders with a sacrificial break point engineered to leave the internal mechanism intact, combined with anti-pick and anti-drill pins. TS007 3-star cylinders meet the highest current rating.

Second: 5-lever mortice deadlocks, common on Victorian and Edwardian timber front doors throughout Earlsfield and the older streets of Wandsworth town. After a forced entry, the lock case itself may be intact even if the frame around it has been damaged — we assess both. A BS3621 5-lever mortice deadlock is the standard that most home insurers expect on the main front door. Third: Yale-type nightlatches on the same doors, which are frequently the first thing to be attacked. We carry replacement nightlatches including high-security versions with anti-snap, anti-pick features. For back doors — particularly uPVC patio doors and French doors — the multipoint lock mechanism and the cylinder both need checking, as patio doors are a secondary target after the main front door has been secured.
