Need a locksmith in Carcroft because your door will not lock or your key has stopped turning? I’m Stephen Fretwell of SF Locksmiths Doncaster. I provide mobile locksmith repairs, replacement locks and security upgrades for local homes, landlords and businesses.
Established in 1999, I identify faulty parts and repair existing doors wherever possible. My van carries a wide range of locks, gearboxes, handles and window fittings. For a quotation, call 01302 378067 or 07990 573857.
Local Locksmith Service Across Carcroft
Carcroft lies in the DN6 area, adjoining Skellow and close to Adwick-le-Street. My service covers homes and businesses around High Street, Askern Road, Skellow Road and the wider Carcroft and Adwick area.
Different doors need different repairs. A wooden door may need a mortice lock or night latch. A uPVC or composite door usually has a euro cylinder that operates a multipoint mechanism. I identify the lock type and explain your options before fitting any parts.
uPVC Door Lock and Gearbox Repairs in Carcroft
If your uPVC door is difficult to secure, the handle may not be the cause. A worn gearbox, damaged hook or roller, or dropped door could be responsible. Forcing the handle can cause further damage and increase repair costs.
My repairs cover:
- Front and rear doors that are jammed or will not lock
- Multipoint gearboxes that have failed internally
- Door hinges, keeps and locking points that need realigning
- Broken handles and worn spring cassettes
- Stiff, seized or damaged euro cylinders
I carry parts for many common systems, including Lockmaster, GU, ERA, Mila, Winkhaus, Fuhr and Fullex. If a suitable replacement part is available, I can often make the door secure again. See my uPVC door repair service.

Lock Changes for Landlords and New Occupants
Carcroft landlords and letting agents may need lock changes between tenancies or after lost keys. I can replace the cylinder, provide new keys and check the existing door mechanism. This helps avoid the cost of unnecessary parts.
I also help homeowners who have recently moved or want better protection against lock snapping. My lock replacement, landlord locksmith and anti-snap cylinder services are available in Carcroft.
Replacing a cylinder, repairing a gearbox and replacing an entire multipoint lock are three different jobs. I will explain which one your door actually needs.
Commercial Locksmith Services in Carcroft
Businesses around Carcroft High Street and the Carcroft Common area also need reliable locks and prompt repairs. I work with commercial door hardware, including mortice locks, cylinders and suitable coded locks.
If keys are lost, a lock is damaged or you need access, I can assess the door and recommend a practical solution. Learn more about my commercial locksmith services.
Composite Doors, Patio Doors and Window Repairs
I repair more than front door locks. Composite doors can develop stiff multipoint mechanisms, while French and patio doors may drop out of alignment. uPVC windows can also develop faulty espagnolette locks, broken handles or worn friction hinges.
Where possible, I replace the faulty part and adjust the door or window so it closes correctly. Read about composite door repairs and patio door repairs.

Frequently Asked Questions About Locksmith Services in Carcroft
Can I keep the same keys after a gearbox replacement?
Usually, yes. The euro cylinder and gearbox are normally separate parts. If the cylinder works properly, replacing the gearbox should not require new keys.
Can you repair locks on a rented property?
Yes. I work with landlords, tenants and managing agents. I can assess the fault, explain the repair and supply replacement keys where required.
Do you charge a call-out fee in Carcroft?
No. I provide a quotation and only charge when the agreed repair or replacement is complete.
