Stiff or Hard-to-Turn Lock
Usually caused by worn internal components, a dry or corroded mechanism, a subtly warped door frame, or a damaged key that has worn down over years of use. Often fixable without replacing the lock.
Stiff lock? Broken key stuck inside? uPVC door that won't close properly? Before spending money on a full lock replacement, call Lockphix. Our same-day lock repair service covers all lock types and door types across North West London — and our policy is always to repair first, and replace only when genuinely necessary.
A faulty lock doesn't always need to be replaced — and at Lockphix, we never recommend replacement unless repair genuinely isn't possible or cost-effective.

Most lock problems follow recognisable patterns. These are the faults our engineers repair across North West London every day.
Usually caused by worn internal components, a dry or corroded mechanism, a subtly warped door frame, or a damaged key that has worn down over years of use. Often fixable without replacing the lock.
This can indicate a seized mechanism, a sheared internal component, or a key that no longer aligns correctly with the lock pins. Proper diagnosis is essential before attempting any repair.
Typically caused by a worn or broken connection between the cylinder and the locking bolt, or a detached cam follower inside the mechanism. In many cases the lock can be repaired rather than replaced.
A snapped key fragment lodged inside a cylinder or barrel requires specialist extraction tools. Attempting removal with improvised tools usually pushes the fragment deeper into the lock.
Most commonly caused by a worn or failed multipoint gearbox — the internal mechanism that drives the hooks and bolts. Door frame misalignment from seasonal expansion or structural movement can also cause this issue.
Wooden door frames swell in damp weather and uPVC frames expand in heat. A lock that becomes stiff during specific seasons is usually a frame alignment issue rather than a lock failure.
Often caused by foreign objects in the keyway, worn key cuts, damaged pins inside the cylinder, or an incorrectly cut replacement key.
Lockphix repairs a wide range of residential and vehicle lock faults across North West London. Each repair begins with a professional diagnosis to determine whether the fault can be resolved without replacing the entire lock.
A stiff or jammed lock is one of the most common locksmith callouts across North West London. In most cases a stiff cylinder or mechanism can be freed, lubricated, and restored to smooth operation without needing a replacement. Lockphix diagnoses the exact cause on the first visit and fixes the issue where possible the same day.
A snapped key lodged inside a lock requires specialist extraction tools. Lockphix removes key fragments from cylinder locks, mortice locks, and ignition barrels without damaging internal components, allowing the lock to continue functioning in most cases.
Internal components such as cams, followers, levers, and springs can wear out or fail over time. Lockphix repairs internal lock mechanism faults across all common lock types in North West London without automatically replacing the entire lock case.
uPVC multipoint systems are complex mechanisms that can fail in several ways. Lockphix repairs faulty gearboxes, broken hooks, worn rollers, snapped sprung bolts, and misaligned keeps, restoring full function to most doors during a single same-day visit.
Mortice locks commonly found in period homes across North West London can often be repaired rather than replaced. Worn levers, broken springs, seized mechanisms, and damaged bolts are frequently repairable with replacement internal components.
Ignition barrels that become stiff, trap keys, or fail to recognise the key properly can usually be repaired. Lockphix diagnoses seized barrels, worn wafers, key profile wear, and common ignition system faults across a wide range of vehicles.
Garage door locks often fail due to worn locking bars, seized T-handles, broken springs, or misaligned mechanisms. Lockphix restores garage door lock systems for up-and-over, roller, and side-hinged doors across North West London.
Window lock faults can create serious security risks. Lockphix repairs espagnolette systems, cockspur handles, sash window locks, and tilt-and-turn window mechanisms across wooden and uPVC frames.
Composite doors combine multipoint locking mechanisms with high-security euro cylinders. Lockphix identifies whether the fault lies within the cylinder or the mechanism and carries out targeted repairs rather than unnecessary replacements.
Period wooden doors often develop issues including swollen frames, worn night latches, damaged mortice bolt connections, and rim lock faults. Lockphix repairs wooden door locks while preserving original door hardware and woodwork.
This is a question Lockphix receives every day. The honest answer is that it depends on the fault, the lock type, and the age of the mechanism. The guide below explains when lock repair usually makes sense — and when replacement is the safer and more cost-effective option.
At Lockphix, our engineer provides an honest on-site assessment during the first visit, including a clear comparison between repair and replacement costs before any work begins. We never recommend replacement simply to increase the job value.
