Assist Locks provides a comprehensive door lock repair service across Isleworth and TW7. Karen repairs uPVC, composite, wooden, timber, French, bi-fold, patio, conservatory, aluminium, and garage door locks. MLA approved, same-day service usually available.
Door locks fail for all kinds of reasons — worn internal mechanisms, snapped keys stuck inside cylinders, misaligned latch bolts, seized gearboxes, and general wear and tear after years of daily use. When a lock on any of your doors stops working properly, you need a locksmith who can diagnose the fault quickly and carry out a lasting repair without replacing more than is necessary.
Karen has been repairing door locks across Isleworth and the wider TW7 area since 2012. She works on every type of door lock you are likely to find in a residential or commercial property — from traditional five-lever mortice locks on Victorian timber front doors to modern multipoint locking systems on uPVC and composite doors. She carries a comprehensive stock of cylinders, mechanisms, springs, gearboxes, and handles in her van so that most repairs can be completed in a single visit without the need to order parts or return another day.
This page covers the repair of lock mechanisms specifically. If your door itself is damaged — for example, if it is dropping on its hinges, sticking in the frame, or letting in draughts — please see our door repairs in Isleworth page instead.
Every door type has its own lock mechanism, and each requires specific knowledge and parts. Karen is experienced with all of the following and can repair or replace the lock mechanism on any door in your Isleworth property.
uPVC and composite doors are fitted with multipoint locking systems that engage at several points along the door edge when you lift the handle. Over time, the gearbox inside the mechanism can wear out, individual locking points can seize, or the euro cylinder can become stiff or snap. Karen diagnoses exactly which component has failed and replaces only the parts that need replacing — whether that is the full gearbox, individual hook bolts and rollers, or just the cylinder itself. She stocks a wide range of multipoint lock gearboxes from manufacturers including Mila, Yale, Fullex, GU, ERA, and Lockmaster, so she can usually match your existing mechanism on the spot.
Traditional wooden front doors across Isleworth are typically fitted with five-lever mortice deadlocks, rim locks such as Yale nightlatches, or a combination of both. Karen repairs and replaces all of these lock types. If your mortice lock is stiff, difficult to turn, or the key no longer engages the levers properly, she can strip the lock down, clean the mechanism, and replace worn internal components. When a repair is not viable, she will fit a new British Standard BS3621 mortice deadlock that meets insurance requirements.
Karen is based locally in Isleworth TW7 and can usually attend on the same day you call. She is available seven days a week, including evenings. For emergency situations where your door cannot be secured, she will prioritise getting to you as quickly as possible. Call 07795 280621 for an immediate quote and availability.
