Lock repairs from £55
Starting price agreed on the phone, extra parts quoted before fitting
Our lock repair service in Sheffield fixes jammed, stiff and broken locks on the spot, starting from £55, with a mobile locksmith usually at your door in 25 to 45 minutes. Our starting point is always the question of whether the lock can be saved, because a surprising number of faults are caused by the door, the keep or a worn key rather than the lock itself.
Use the table below to match your symptom to the likely cause, then call us and describe what you are seeing. That description alone often tells us whether we need to bring a part.
Lock problems diagnosed: symptom, cause and fix
| What you notice | Most likely cause | Usual fix |
|---|---|---|
| Key goes in but will not turn | Worn key, worn pins, or the bolt is binding on the keep | Test with the door open; adjust keep or replace cylinder |
| Key turns only with the door pushed or pulled | Door has dropped or the frame has moved | Hinge or keep adjustment, no new lock needed |
| Key is hard to insert | Debris or dried grease in the keyway, or a badly cut copy | Clean and lubricate; try the original key |
| Handle floppy, latch does not pull back | Broken follower spring or snapped spindle | Replace the spring, spindle or lock case |
| Bolt throws halfway then stops | Keep hole too shallow or misaligned | Re-cut or move the keep |
| Latch does not catch when the door closes | Keep out of line after the door swelled or settled | Adjust the keep or the door |
| Lock worked yesterday, now completely seized | Internal part broken | Replace the mechanism or the whole lock |
On uPVC doors with a handle that will not lift, the cause is usually the gearbox or the door alignment, which our uPVC door not locking page covers in detail.
The one test worth doing before you call
Open the door and try the key or handle with the door standing open. This takes ten seconds and splits almost every lock fault into two groups.
Works fine with the door open
The lock is healthy. The bolt or hooks are hitting the frame because the door has dropped, swollen or the keep has moved. This is an adjustment job and often the cheapest repair we do.
Tell us this on the phone.
Still stiff or stuck with the door open
The fault is inside the lock, the cylinder or the key. Stop forcing it, because that is how keys snap and gearboxes break.
A repair or replacement part is likely.
One caution: on a door that only locks with a key on both sides, do not close it while testing if you are unsure the key will work again.
Why we repair before we replace
A good quality five lever mortice lock or a well made multipoint mechanism can last for decades. When one stops working, the failure is often a single part: a spring, a follower, a keep, or a key worn to the point that it no longer lifts the levers properly. Replacing that part keeps a lock you already trust and keeps the cost down.
We will recommend a replacement instead when the lock is genuinely worn out, when parts for that model are no longer made, when keys are unaccounted for, or when the lock falls short of what your insurer asks for. In those cases our lock replacement service takes over, and we explain the difference in price before deciding.
Door lock repair on different types of lock
Mortice locks
Sashlocks and deadlocks in timber doors, common in the older streets of Sharrow, Crookes and Hillsborough. Typical faults are a broken latch spring, a seized bolt and levers worn by years of use.
Nightlatches
Yale style rim locks where the snib sticks, the latch drags or the case has worked loose from the door. Replacements are covered on our Yale lock replacement page.
Euro cylinders
The barrel in uPVC and composite doors. Worn cylinders are usually cheaper to replace than repair, from £20.
Multipoint mechanisms
Gearboxes, hooks and rollers along the edge of uPVC and composite doors. See multipoint lock repair for how these are diagnosed.
We also repair window locks, gate locks and garage locks; the full list is on our locksmith services page. Keypad and app controlled locks that have stopped responding are handled through our smart lock fitting and repair service.
Why Sheffield locks play up in winter and wet spells
Timber doors on the older housing stock across the west of the city take on moisture through damp autumns and swell in the frame, which pushes the bolt out of line with its keep. In cold snaps the metal parts contract and old grease thickens, so a lock that was merely stiff becomes one you have to fight. uPVC doors move the other way in hot summer weather, expanding enough that hooks no longer meet the keeps.
For stiff keys, a lock lubricant made for the job (dry PTFE or graphite types) is better than household oil, which collects grit. If a lubricant does not help within a couple of tries, call rather than force it.
Signs a lock is about to fail
Locks rarely die without warning. Calling at the first of these signs is cheaper than calling after the door has jammed shut with you on the wrong side of it.
- You have developed a technique. Lifting the handle just so, jiggling the key, leaning on the door. Each workaround puts extra load on a part that is already struggling.
- The key has gone shiny and rounded. Worn teeth stop lifting pins or levers fully, and a worn key is far more likely to snap.
- The handle droops or does not spring back level. A tired return spring in a lock case or gearbox.
- Grinding or clicking from inside the door. Something has broken or come loose in the mechanism.
- Gaps or rubbing marks around the frame. Evidence the door is moving and dragging the bolt with it.
Landlords managing several properties can save on repeat call outs by having all of these checked at once; our landlord locksmith service is set up for that.
