Faulty Lock Assessment and Repair
Door Lock Repair Services in Brighton
Key sticking or door not latching? Describe the fault.

Does Your Door Lock Need Repair?
A lock does not always fail completely without warning. You might notice a key becoming harder to turn, a latch catching on the frame or a handle that no longer returns smoothly. The City Locksmith Brighton assesses faulty door locks and explains whether adjustment, repair or replacement is the sensible solution.
We work with enquiries about common residential locking systems, including cylinder locks, mortice locks, night latches and multipoint door mechanisms. The aim is to understand why the problem has developed rather than simply replace parts without checking the cause.
Finding the Cause of a Lock Fault
Lock problems can be caused by worn components, damaged keys, loose fittings or doors that are no longer sitting correctly in their frames. A fault that appears to be inside the cylinder may instead be affected by pressure on the bolts or latch. Forcing the mechanism can turn a minor difficulty into a more expensive repair.
We start with the symptoms and assess the condition of the door and locking hardware. Some faults are suitable for adjustment or component-level repair. Others involve damage or wear that makes replacement more appropriate. We explain the difference and the available options before beginning chargeable work.
Common lock repair situations
Stiff Key Operation
If your key only turns with force or needs repeated movement, stop before the key snaps or damages the cylinder. The problem may involve wear, contamination, alignment or another internal fault. We consider the likely cause and whether safe adjustment or repair is practical.
Door Not Latching Properly
A door that needs lifting, pushing or slamming to latch may have an alignment issue. The latch, strike plate, hinges or frame may need attention. A correctly operating door should not require excessive force during ordinary use.
Loose or Faulty Handles
A loose handle can be caused by fixings, spindle wear or faults within the connected mechanism. We inspect the apparent cause and discuss whether tightening, adjustment or replacement of the affected component is appropriate.
Multipoint Mechanism Faults
Multipoint locks use interconnected parts to secure several points of a door. Problems can involve the central gearbox, hooks, rollers, keeps or door positioning. We consider whether the faulty component is serviceable and whether suitable replacements are available.
Night Latch Problems
A night latch may become unreliable because of wear, damage or poor alignment with its keep. We assess how it operates and whether a repair is sensible. An old or badly damaged latch may be better replaced than repeatedly adjusted.
Worn or Damaged Cylinders
A cylinder may fail through wear or physical damage. Some apparent cylinder problems may also be caused by another part of the door. We assess the lock and explain whether replacing the cylinder alone would resolve the issue.
Recurring Lock Problems
If a lock has been adjusted several times but continues to fail, it is worth investigating the underlying cause. Seasonal door movement, ageing hardware or poor alignment can contribute to repeated faults. We discuss repairs with long-term reliable operation in mind.

Lock Repair Costs
| Type of work | How it is priced | What affects the price |
|---|---|---|
| Minor lock adjustment | Quoted by work required | Varies by fault |
| Latch or handle repair | Quoted after assessment | Varies by component |
| Cylinder fault | Repair or replacement quoted | Varies by condition |
| Multipoint mechanism repair | Quoted by parts and labour | Depends on mechanism |
Repair costs depend on the underlying fault, accessibility, labour time and parts. Some components cannot be economically or safely repaired and will require replacement. We discuss the available options and charging basis before proceeding.
Repair where practical
We consider whether the existing hardware can be restored to reliable operation.
Underlying causes matter
We look at door alignment and connected fittings, not only the lock itself.
Clear repair choices
We explain when replacement may be more sensible than further repair.
Everyday usability
