What a Lock Change After a Break-In Actually Involves
Burglars rarely leave a lock in a usable condition. A forced front door may have a bent or snapped euro cylinder, a sprung or broken 5-lever mortice deadlock, or a multipoint locking mechanism that no longer aligns with the keep. Even where the door itself looks intact, the cylinder may have been attacked with a technique that leaves it compromised in ways that are not obvious at a glance. Our first step is always a thorough assessment of every locking point that was targeted — and of any secondary doors or ground-floor windows that could now be reached from inside. We then confirm an exact, up-front price before any work begins, so there are no surprises on the invoice.
On uPVC and composite doors — the most common type found on newer properties and many houses in the Fieldgate area — the euro cylinder is the primary target for snapping attacks. We replace these with anti-snap, anti-drill, anti-pick cylinders rated to TS007 3-star, the standard most home insurers recognise. On older timber doors we focus on the Yale-type nightlatch and the 5-lever mortice deadlock; we carry British Standard BS3621 mortice locks as standard stock, which is the specific grade insurers frequently require following a claim. For commercial premises, the requirements differ — heavier-duty cylinders, multiple access points and sometimes a master-keyed arrangement — and our commercial lock change service accounts for all of that.
