Lock Replacement & Repair —
All Types, All Brands

Lock replacements start from £85 plus parts. Parts range from £15 to £120+ depending on the lock type and security rating. A standard Euro cylinder replacement is typically at the lower end. A BS3621 mortice deadlock fitting, or a high-security cylinder with restricted keyway, will be higher. An exact quote including parts is always confirmed over the phone before attending. No call-out fee, no surcharge for evenings or weekends.

No. There is no call-out fee across Nottingham (NG1–NG16), Derby, Mansfield and covered surrounding areas. The price agreed over the phone is the price for the completed job — no additional charge for attending and no premium for same-day, evening or weekend callouts.

Yes, always. Max will ask about the door type, the lock type if known, and the reason for the replacement. From that he gives an indicative cost range over the phone. The exact quote — including the cost of parts — is confirmed before any work starts. No surprises.

A TS007 3-star anti-snap Euro cylinder has a built-in sacrificial snap point. If a burglar attempts to snap it — the most common forced-entry method on uPVC and composite doors — the cylinder breaks at that engineered point while the internal cam remains intact and the door stays locked. Standard Euro cylinders protruding 3mm+ from the face plate can be snapped in under 20 seconds. Nottinghamshire and Derbyshire Police both recommend TS007 cylinders on all uPVC and composite doors. If your door has a standard cylinder, upgrading is the single highest-return security improvement available.

Stand outside your closed door and look at the cylinder. If any part of it protrudes beyond the face of the door — even just 2–3mm — it can be snapped. Also check whether it has any anti-snap markings (TS007, 3-star, or a BSI kitemark). If you’re unsure, send Max a photo on WhatsApp and he’ll tell you within minutes.

Apecs, Ultion, ABS Avocet, Yale Platinum, ERA Fortress, Brisant Secure, Ingenious and others depending on the specification needed. All TS007 3-star rated. Max will advise on the right brand for your door type and security requirements over the phone.

Yes. Keying alike means fitting cylinders cut to the same key profile — so your front and back door, or multiple entry points, all open with one key. Works for both residential and commercial properties. Discussed and quoted at the time of booking.

Some high-security cylinders — including certain Apecs, Ultion and ABS models — include a lockdown function. When engaged from inside, the cylinder cannot be turned from the outside — even with the correct key. Useful for overnight security or high-value properties. Max can advise on whether your door is compatible during the phone consultation.

BS3621 is the British Standard for security mortice deadlocks fitted to external timber doors. It requires a minimum of 5 levers, 1,000 key differs, a hardened steel anti-saw bolt, and a bolt that cannot be pushed back without a key. Many home insurance policies may require a BS3621 lock on external timber doors as a condition of cover. If your timber door has a 2- or 3-lever lock, or a lock with no BS3621 stamp on the case, it is likely not insurance-compliant. Max fits and certifies BS3621 locks across Nottingham, Derby and Mansfield, same-day available.

Open the door and look at the body of the lock. A genuine BS3621 lock will have “BS3621” or the BSI kitemark stamped on the faceplate or case. Count the levers — it should say “5 Lever” or “5L”. Finally, turn the key twice and try to push the bolt back by hand — a BS3621 bolt will not move. If any of these checks fail, the lock is not compliant. Call Max and he’ll advise on the right replacement.

Yes. Old rim locks — common on Victorian and Edwardian front doors across Nottingham’s NG3–NG7 belt — can be replaced with a modern BS3621 mortice deadlock or a deadlocking night latch without damaging the door or its period furniture. Max takes particular care with period properties to preserve the door’s aesthetics. Both the new lock and any period handles are confirmed complementary before fitting.

A sash lock combines a deadbolt and a latch in a single unit. The latch allows the door to close automatically without a key; the deadbolt locks it fully when the key is turned. Common on timber front and back doors. BS3621-certified sash locks are available and provide insurance compliance for both the latch and deadbolt functions in a single fitting.

The simplest way to tell: if the handle lifts and the locking points engage but the key won’t turn, it’s the cylinder. If the handle doesn’t lift smoothly, or the locking points don’t all engage, it’s likely the multipoint mechanism. Max diagnoses this over the phone in most cases — though for unusual faults he may need to attend and assess up close before confirming.

In most cases yes — for uPVC and composite doors with Euro cylinders, the cylinder can be swapped independently of the mechanism. For timber doors with mortice locks, the lock body and cylinder are separate components and can usually be addressed individually. Max will confirm which approach applies to your door during the initial phone call.

GU, Mila, Fullex, ERA, Avocet, Winkhaus, Fuhr, Roto, Yale, Nico and AGB are the most common. Max identifies the existing mechanism by backset, case measurement and hook configuration, then sources the correct replacement. Most are replaced on the first visit.

A standard Euro cylinder tenancy change — the most common type — takes around 15 minutes per door. Max works with landlords and letting agents across Nottingham, Derby and Mansfield for fast tenancy changes that minimise void periods. Multiple doors can be changed in a single visit and keyed alike if required.

There is no specific statutory requirement, but it is strongly recommended as best practice and is increasingly required by letting agents and property management companies. If a previous tenant retains a key copy, there is no way to know without a lock change. Most landlords consider it standard procedure — the cost is low relative to the risk.

Yes. Max works with letting agents and property managers across Nottingham, Derby and Mansfield for tenancy lock changes, security upgrades and emergency callouts. Fast turnaround is prioritised to minimise void periods. Contact Max →

Yes. Commercial lock replacement and repair is carried out at the same rate as residential — no commercial surcharge. Max covers offices, retail premises, cafes, restaurants, car dealerships and industrial units across Nottingham, Derby and Mansfield. Adams Rite, patch fitting, restricted keyway, high-security commercial and access control cylinders all covered.

Yes. Frameless and minimal-frame glass shopfront doors use specialist patch fitting locks or Adams Rite deadlatches. These require specific knowledge and parts that many general locksmiths won’t carry. Max attends commercial glass door callouts across Nottingham city centre and Derby, typically same day.

A restricted keyway cylinder uses a key profile that cannot be cut at a standard key-cutting shop without the owner’s authorisation. This means that even if an employee or former tenant has a key, they cannot get copies made without your knowledge. Particularly useful after a staff change. Max fits restricted keyway systems for commercial and residential clients.

Call 101 (or 999 if the intruder may still be on the premises) and obtain a crime reference number. Do not disturb the scene until police have attended. Then call Max — he responds 24/7 to post-burglary callouts across Nottingham, Derby and Mansfield. He will secure the property, identify all entry points, replace compromised locks with TS007 anti-snap cylinders as standard, and provide a written report if required by your insurer.

Yes — and you won’t need a burglary to get it. Max carries TS007 anti-snap, high-security and BS3621-certified locks on every job. The locks fitted after break-ins are available as standard upgrades at any time — same price, same visit. Most customers who upgrade after a burglary say they wish they’d done it sooner. You don’t have to wait.

Yes. Bi-fold doors use multipoint locking systems and Euro cylinders — Max replaces both. The mechanism is identified by brand and fold configuration, then replaced with a compatible unit. Anti-snap cylinder upgrades are available for bi-fold doors as standard.

Yes. Stable doors have separate upper and lower locking systems. Max replaces the locks on both halves — night latch or cylinder on the upper, mortice or euro cylinder on the lower — and ensures both operate correctly together.

Yes, but fire door lock replacements must use fire-rated hardware to maintain the door’s certification. Max fits fire-rated cylinders, handles and mortice locks that comply with the door’s original specification. This is particularly relevant for HMOs, commercial premises and communal areas in apartment buildings.

In most cases yes. The symptom pattern — whether the key turns, whether the handle lifts, whether the fault is sudden or gradual — tells Max a great deal before he arrives. He can usually identify the likely cause and give an accurate cost range over the phone. In some cases he may need to attend and inspect up close before confirming the exact replacement needed.
