Need a Door Lock Replaced in Wilmslow?
New home, lost or stolen keys, or a lock that has worn out or been damaged: those are the usual reasons for a replacement. Craven Locksmiths Wilmslow supplies and fits replacement locks for front, back and internal doors, and communal entrances, across Wilmslow, normally in one visit.
Supply and fitting come from the same person, and there is no call-out charge. When it cannot wait, see emergency lock replacement.
What Part of the Lock Actually Needs Replacing?
Here is something worth knowing before you pay for a new lock in Wilmslow: the thing on your door is normally made up of several separate components. A problem with one component is not, on its own, a reason to replace the whole system.
The barrel or cylinder
Also called the barrel, the cylinder accepts the key and is operated by it. It is the euro cylinder you will find on many uPVC, composite and aluminium doors. Put a new one in and you get a new set of keys, while the mechanism and the other door hardware carry on as before. Depending on which product is selected and the door it is for, the available options may include keyed-alike or thumb-turn versions.
The lock mechanism or case
The lock case contains the components that do the work inside the door. A timber door may use a mortice lock case, and a uPVC or composite door may use a gearbox connected to a multipoint strip. Replacing this mechanism involves more work than a cylinder change, and it may be needed where the working components have failed but the cylinder is still usable.
The lockset as a whole
A complete lockset can include the cylinder, the internal mechanism, the handles and associated fittings. Replacing all of it may be appropriate if several parts are damaged, if compatible parts cannot be sourced, or if the door needs a security upgrade.
Finding the failed part first means safe, serviceable components are not replaced unnecessarily. You can read about our uPVC door lock service and.
Changing the Locks After Moving to a New Home
Getting the keys to a new home is a good moment to review access to it. The keys you are handed may not be the only ones: copies could still sit with previous owners, tenants, estate or letting agents, or contractors, and the number made is rarely known.
Swapping the external cylinders makes any existing key unusable and puts you in charge of a brand-new set. If the doors share compatible locks, keyed-alike cylinders may be available so that a single key opens more than one entrance, which saves carrying a separate key for the front, back and side doors. Many homeowners are unaware that this is possible, and it is one of the best reasons to do all of the external doors at once after moving house rather than one at a time.
Lock Types Found on Homes and Businesses in Wilmslow
No single lock suits every door: the correct replacement turns on the door, its hardware and the failed component.
Mortice lock
A mortice lock sits within the edge of a timber door, its complete case enclosed by the door instead of fixed to the surface. Some timber final-exit doors carry five-lever mortice locks certified to BS 3621. Insurers' required standards differ, so check your own policy.
Nightlatch
These are screwed to the inner surface of many timber doors. People often say "Yale lock", yet Yale is one brand, not a term for all nightlatches. Condition permitting, its rim cylinder can be swapped alone.
Euro cylinder
Typical on uPVC, composite and aluminium doors, changing one gives new keys and leaves the remaining mechanism alone. Correct sizing matters, since a cylinder that projects too far can weaken security. Thumb-turn or keyed-alike versions may suit, subject to door and product.
Locks on composite doors
Most composite doors combine a euro cylinder with a multipoint mechanism. The cylinder may be replaceable separately; fitted hardware, measurements and what failed decide.
Multipoint mechanism
This long strip inside uPVC and composite door edges locks at several points once operated. A full mechanism change is a bigger job than a cylinder swap and has to be compatible with the existing hardware.
Internal door locks
Internal timber doors may have mortice latches, sashlocks or privacy locks. The use of the room, and whether it needs a key, handle or privacy function, decides the replacement.
Should You Replace a Lock Rather Than Repair It, and When?
In Wilmslow, plenty of lock problems can be put right without fitting a new lock. A repair, some adjustment or a smaller replacement part can sometimes restore reliable operation. Our recommendation comes after assessing both lock and door, and it rests on which component has failed, how extensive any damage is and whether the lock is still secure.
Repair is enough, often
- Door shut, lock stiff: it turns freely while the door is open and becomes difficult when closed.
- Loose handle: the handle moves about, but the locking mechanism keeps working.
- Stiff key: the key is hard to turn, yet the cylinder is found to be serviceable on inspection.
- Dropped door: the door has slipped slightly and is out of line with the frame.
These may be signs of an alignment, handle or repair issue rather than of a lock that needs replacing outright. Inspection is still how the cause gets identified.
Replacement is usually the right call here
- Missing keys: lost or stolen and not accounted for.
- New occupants: you have moved in and want old keys to stop working.
- Worn out: inspection finds the cylinder or internals too worn for a reliable repair.
- Forced entry: the lock or a component is damaged beyond repair.
- Insurance: your policy specifies a standard the existing lock does not meet.
New keys accompany a replacement key-operated cylinder or a replacement keyed lock in its entirety.
Replacing Locks When Keys Are Lost or Stolen
A missing key is only a problem if someone else could use it. That is why a lock replacement is not always required after a loss: it depends on where the key disappeared, whether it was stolen and whether it could be connected with where you live.
Entry to your home may still be possible with keys whose whereabouts are genuinely unknown. Another cut key will let you in again, but the missing copies would still turn the existing lock. Doors with a separate replaceable cylinder may only need that cylinder changed. Doing so makes every key for the old cylinder unusable and hands you a new set, while the handles and other door hardware that remain serviceable can stay put.
How Does the Job Work?
The process is the same whether it is a front door cylinder or a back door mortice lock:
- You let us know the kind of door and what the issue is, adding a photo of the lock if you are not certain what is fitted.
- We pinpoint the part that needs replacing and give you the price.
- You are given all of the new keys.
One visit is usually enough for a single lock replacement.

The Security Standards Your Insurer May Expect
Before you choose a replacement lock, look at your insurance documents. Some home insurance policies specify the type or security standard of lock required on external doors, and what they ask for varies by insurer, policy and door type. If the wording is unclear, ask your insurer directly.
On timber doors, the standard usually discussed is BS 3621. A policy may specify a mortice lock or nightlatch certified to BS 3621 for a suitable timber final-exit door. Note that a five-lever lock is not automatically BS 3621 certified, so check the lock for the relevant marking rather than relying on the number of levers.
Many doors made from uPVC, composite or aluminium have euro cylinders fitted. The recognised anti-snap ratings for these include TS 007 3-star and SS312 Diamond, though the appropriate choice depends on the door, handles and locking system already in place.
Be wary of "insurance approved" as a label. It does not mean every insurer accepts the same lock: certification shows a product meets a recognised standard, and your insurer decides what its policy requires. We can identify the existing lock and its visible security markings, but your insurer should confirm whether a standard meets your conditions. See BS 3621 door locks and anti-snap door locks.

By age, 10.8% date from before 1900 and 19.3% from 1900 to 1939, against 39.1% from 1945 to 1982, 19.8% from 1983 to 2008 and 10.8% from 2009 on (VOA council tax property stock, 31 March 2026). Older timber doors often carry mortice locks, while later houses mostly have uPVC multipoint mechanisms.
The national planning dataset records no conservation area for Wilmslow (planning.data.gov.uk, October 2026), but it has known gaps, so that means unknown rather than none, and it does not show whether an Article 4 direction restricts doors. Ask the council before replacing a door; the lock inside is a separate matter. See all areas we cover.

Frequently Asked Questions
Do I need a whole new lock or just a new barrel?
Just the barrel, more often than not. People tend to ask for a whole new lock when the euro cylinder is the only part at fault. On uPVC, composite and most aluminium doors, that cylinder can be replaced separately, and you end up with a working lock and new keys. The full mechanism needs replacing only if the gearbox or lock case inside the door has failed, a less common and larger job. We quote on the call from your description; only a different job on site can change it, and you are told before work starts.
How long does it take to replace a door lock?
Replacement time varies from one lock job to another. Cylinder changes tend to involve less work than replacing a multipoint mechanism or mortice lock case. The state of the door may alter what is needed, and a suitable replacement part must be available. Looking at the lock helps establish the likely timing.
Should I change the locks when I move house?
Yes, it is worth doing. There is no telling how many keys exist or who has them: previous owners, tradespeople, letting agents and former tenants may all have one. Fitting new external cylinders makes every old key useless. It is a short job that can be booked for a weekday between 7am and 6pm, you hear the price first, and there is no call-out charge.
I have lost my keys. Do I need the lock replaced or just new keys cut?
If you cannot account for the keys because they were stolen or lost away from home, change the cylinder rather than just cutting new keys. A cut key does not stop the old ones opening your door. A replacement cylinder does, because every previous key stops working and a new set is supplied. Where the keys could not be connected with your address, a replacement may not be required at all.
Will a new lock meet my home insurance requirements?
The honest answer is that it depends on your policy. Some home insurance policies specify a British Standard BS 3621 lock on suitable timber final-exit doors, or a properly rated cylinder on uPVC and composite doors. With requirements varying by insurer, door type and policy, check your wording or ask your insurer. "Insurance approved" is shorthand: the standard is certified by BSI, but the requirement is set by the insurer.
What is an anti-snap lock and do I need one?
It is a cylinder engineered to resist lock snapping, which means breaking the barrel in two to open the door. In the UK, recognised ratings include TS 007 3-star and SS312 Diamond. Do you need one? That depends on your door and your insurer, but for uPVC and composite front doors it ranks among the more worthwhile upgrades, and it can be included in a routine cylinder replacement.
How much does it cost to replace a door lock in Wilmslow?
Several things set the price: which part is being replaced, the security rating you pick, the door type, how many doors and the time of day. A cylinder is the cheapest swap and a full multipoint mechanism the most expensive. Describe the door and lock when you ring, and the price holds unless the job on site proves different, in which case you are told before any work starts. No call-out charge.
Can you replace locks on a rental property between tenancies?
Yes. Swapping external cylinders between tenants is routine, and it can be booked around the changeover date. In Wilmslow 16.2% of households rent privately and 10.0% from social landlords (Census 2021, ONS), so check the tenancy agreement for what is allowed; we can fit a like-for-like lock the landlord will accept. Landlords with several addresses can group the work under one price.
