Common Faults
What's Wrong With Your Lock?
Most lock faults fall into one of these categories. The majority can be resolved on the same visit without full replacement — saving you time and money.
Key Turns But Door Won’t Lock
The bolt or latch isn’t fully engaging with the keep plate. Usually a door alignment issue or worn mechanism — and a security vulnerability that needs addressing immediately.
Stiff or Difficult to Turn
The most common complaint. Caused by internal wear, debris, or door misalignment. Left untreated, stiff locks often seize completely — best dealt with early.
Key Snapped Inside the Lock
A broken key lodged in the cylinder can often be extracted without replacing the barrel. Our specialist extraction tools remove the fragment in most cases without further damage.
Lock Feels Loose or Wobbly
Movement in the lock body indicates loose fixing screws, a worn spindle connection, or a failing backplate — all straightforward field repairs with the right parts.
Multipoint Lock Not Engaging
When the gearbox, cam followers, or hook bolts fail, the door appears closed but isn’t locked — a critical security flaw we can often fix on the same day.
Lock Freezing or Seizing
Condensation, cold weather, or lack of lubrication causes internal corrosion and seizing. Professional cleaning and lubrication restores smooth function.
Our Process
How a Lock Repair Works
From your first call to a perfectly working lock — here’s exactly what you can expect at every stage of our repair service.
You Call — We Diagnose Remotely
Tell us what’s happening with your lock. You can WhatsApp a short video of the problem — we’ll often diagnose remotely and give you an accurate quote before we leave.
Fixed Quote Given on the Phone
We give you a fixed price before we travel. No call-out fee, no surprises. If we arrive and find something unexpected, we’ll tell you before proceeding.
On-Site Diagnosis & Root Cause Check
We carry out a full inspection — checking for underlying causes like door misalignment or hinge drop that may have contributed to the fault. Fixing the root cause prevents the same issue returning.
Repair Carried Out on the Spot
Using quality replacement parts meeting British Standard specifications, we repair your lock cleanly and thoroughly — testing it from both sides before declaring the job complete.
Signed Off With a Guarantee
We confirm you’re satisfied before we leave. All repair work is covered by our workmanship guarantee — if the same fault recurs due to our repair, we’ll fix it at no cost.
Lock Types
Every Lock Type We Repair
From traditional mortice locks to modern multipoint uPVC mechanisms — our locksmiths are trained on every residential and commercial lock type used in the UK.
When to Call Us
Don't Wait Until It Stops Working
Many lock failures give warning signs long before they become a full security problem. If you’re experiencing any of these situations, call us today for a same-day assessment.
Your key is stiff or difficult to turn
A warning sign of internal wear, debris, or door misalignment. Catching it early means a simple repair — ignoring it means a lockout.
Repair SoonThe key turns but the door won’t lock
Your home isn’t properly secured. A security risk that needs same-day attention — don’t leave it overnight.
UrgentA key has snapped inside the lock
We extract broken keys without replacing the lock barrel in most cases. The sooner you call, the more likely a clean extraction.
Call NowYour lock feels loose or wobbly
Loose fixings and worn spindle connections get worse over time. A quick repair now avoids a more expensive job later.
Repair SoonYour uPVC door handle has dropped
A dropped handle almost always means the gearbox has failed. The door may look closed but it isn’t locked — a critical issue.
UrgentYour lock freezes or seizes in cold weather
Preventable with professional lubrication. If your lock is already seizing, a service now avoids complete failure in winter.
