Need a New Lock Fitted in Woking?
Front door with only a latch, or an insurer asking for something better? Woking Locksmith supplies and fits new locks on doors, windows, outbuildings and gates across Woking, including British Standard and high-security locks chosen to match what an insurance policy asks for. There is no call-out charge. Call 01483 377197.
Most people get in touch for one of four reasons: a door that has no lock, or only one; an upgrade to satisfy an insurer; a new or replacement door waiting for its locks; or an internal room, office, shed or gate that needs securing. When you ring, describe the door, how it gets used and anything your insurer, landlord or managing agent has put in writing. The options are explained in plain terms and the price is agreed before installation begins. If a lock is already in place and simply needs swapping, our lock replacement page is the better fit.
Fitting a New Lock or Replacing an Existing One?
The two jobs sound alike but start from different places. Fitting means creating a locking position where none existed, adding another lock, or upgrading to a different type or standard. Replacing means taking out a lock that is already there and putting a like-for-like one in its place. Which service you need depends on whether the door needs a new locking position or an existing lock just needs changing.
When you need a lock fitted
A new lock is usually the answer when a door lacks suitable hardware, needs an extra locking point or needs key-controlled access:
- A door with no lock at all, or only a nightlatch where your insurer also wants a deadlock
- Moving up to a British Standard or anti-snap lock
- A new, replacement or newly hung door that needs a compatible lock, cylinder and handles
- An internal room, office, outbuilding, shed or side gate that needs securing
- A secondary lock on a patio or French door, where the existing configuration leaves room for one
When you need a lock replaced instead
Swapping an existing lock is a different job, and it is usually the right one when:
- Keys have been lost or stolen
- You have just moved in
- The lock is worn, stiff or failing
- The door has been forced
For any of these, go to lock replacement in Woking, where the swap is covered in full.
Either way, the door and frame are checked first, because they decide which locks and fitting positions are realistic. The specification turns on the door's material, thickness, construction and how it will be used, and the whole door-and-lock arrangement has to be looked at together rather than the lock on its own.
Does Your Lock Actually Meet Your Insurance Requirements?
Plenty of homeowners assume the locks on their doors satisfy their policy. A good number are wrong and have no idea until they read the small print after a break-in.
A five-lever lock is not automatically a BS 3621 lock
Generic five-lever mortice locks from DIY shops often carry no British Standard kitemark, and the number of levers alone does not confirm that a lock meets BS 3621. Many were fitted by previous owners or during budget refits. To check yours, open the door and look at the faceplate on its edge for the kitemark symbol and a BS number. Go by the markings and certification, not the five-lever label: no kitemark means no confirmed compliance, however many levers it has.
A cheap euro cylinder can be snapped in seconds
On uPVC and composite doors the weak point is usually the cylinder. A basic hardware-shop euro cylinder offers little resistance to snapping, which is a common way these doors are attacked. Some insurers now specify a TS 007 3-star or SS 312 Diamond rated cylinder; look for the stars or the Diamond mark on the cylinder face. The full picture is in our guide to anti-snap locks and lock snapping, and uPVC work is covered on our uPVC door locks page.
The right lock is decided by the door's construction, where it sits, how it is used and how people need to get in and out. Before choosing a product, it is worth reading any written instructions from your insurer, landlord or managing agent, because a lock that suits one door can be the wrong choice for the next. The things that shape the choice:
- What the door is made of: timber, uPVC, composite or aluminium
- Whether it is an external door or an internal one
- The thickness of the door, the frame and any preparation already cut into it
BS 3621, BS 8621 and PAS 3621: Which Standard Applies to Your Door?
"Insurance approved" is shorthand: BSI certifies a product against a standard, but each insurer writes its own conditions. There is no single standard that every insurer follows. Many of the large UK insurers take guidance from RISCAuthority, yet each still sets its own policy wording, which is why two policies on similar houses can ask for different things. Some policies specify a particular standard; check yours rather than assume. Depending on the product, certification may include a TS 007 star rating or an SS 312 Diamond rating.
| Standard | What it covers | Where it tends to apply |
|---|---|---|
| BS 3621 | A tested thief-resistant single-point lock operated by key from both sides | Commonly associated with suitable external timber doors |
| BS 8621 | A tested thief-resistant single-point lock operated by key from outside, with keyless exit from inside | May be relevant where keyless egress is required, such as a flat or an HMO escape route |
| TS 007 / SS 312 | Security ratings used for cylinders and related door hardware | The required rating depends on the door and any documented requirements |
PAS 3621 is the equivalent standard applied to multipoint locking systems on uPVC and composite doors.
Fire doors, flat entrance doors and communal entrances need extra care. Any lock fitted there has to work with the door's fire-safety and escape requirements, and it must not stop the door closing properly or weaken its resistance to fire and smoke. Approval may be needed first where the door belongs to a rented or leasehold property, a flat in a managed building, or a communal entrance or shared area. For more depth, read BS 3621 and insurance-approved locks explained or types of door locks explained.
Locks We Fit on Woking Properties
Which lock suits a door comes down to its material, the space available for fitting, how it will be operated and any security requirement you have been given. Below are the main types, with the brands carried still to be confirmed. [CLIENT TO CONFIRM: lock brands carried]
Mortice deadlocks
A mortice lock sits inside the edge of a suitable timber door, and the range covers deadlocks and sashlocks, with certified versions where a recognised standard is needed. The five-lever BS 3621 version is what many insurers look for on a timber final exit door. Fitting one where none exists means cutting a pocket into the door after its thickness, construction and frame have been checked: skilled work, not a DIY job. See BS 3621 explained.
Euro cylinders and anti-snap upgrades
Euro cylinders work inside compatible lock cases and multipoint systems on uPVC, composite and some aluminium or timber doors. Moving from a standard cylinder to a TS 007 3-star or SS 312 Diamond rated one is among the quickest security gains available, and is often what an insurer is after. The cylinder must be sized correctly for the door and its protective hardware: one that sticks out too far is a weakness in itself.
Nightlatches and rim locks
These are fitted to the surface on the inside of suitable timber doors, and most people call them a Yale-type lock. Models differ in how they lock, open and deadlock. Whether one works as the main lock or an extra depends on the door and the product, but a nightlatch on its own rarely satisfies an insurer on a final exit door, which is why a mortice deadlock usually goes in alongside it.
Internal, outbuilding and gate locks
Shared houses and offices often need locks on individual rooms, and sheds, garages, outbuildings and side gates need them too. Side gates and outbuildings are a common way to reach a hidden rear door, so they are worth securing even though insurers rarely mention them. Business work is covered under commercial locksmith; garage locks will have their own garage door locks page.
Window locks
Many policies specify key-operated locks on accessible windows, particularly on the ground floor. Window work has its own page:.
Proof of What We Fitted, for Your Insurer
If you ever claim after a break-in, your insurer may ask which locks were on the doors and whether they met the policy. Saying so is not evidence; paperwork is. [CLIENT TO CONFIRM: that an itemised invoice naming the lock and its standard can be provided as standard on every installation] Once confirmed, each fitting would come with:
- An invoice naming the lock and the standard it meets
- A note of which doors it was fitted to
- The rating, where the cylinder fitted carries one
Keep it with your policy documents; it also helps later with replacement parts.
Locksmith pricing
What Affects the Cost of Fitting a New Lock
An installation price has not yet been published, so none is given here. [CLIENT TO CONFIRM: whether an installation starting price can be published] What drives the figure is the lock, the door and the preparation the door needs. Fitting into a door with no existing provision takes longer than a straight swap, because the door has to be cut or bored first. The main factors:
- Whether the door is already prepared or needs cutting
- The lock type and security rating chosen, plus any extra hardware
- The door material and the work needed on the door or frame
- How many doors are being done
- The time of day the work is carried out
There is no call-out charge, and the price is given on the call from what you describe; if something on site changes it, you hear before any work starts. Weekday working hours run Monday to Friday, 7am to 6pm, and evenings, nights, weekends and bank holidays are charged at a higher labour rate. You pay for the work carried out, any parts needed, and VAT. Rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged.
To get a price for your door, call 01483 377197. For a wider view, see our full guide to locksmith prices in Woking.

Service required, time of attendance, lock and door type, labour and parts.
How the Job Works
- Tell us the door type and what you want to achieve, including anything your insurer has asked for.
- We confirm which lock suits the door and the requirement, and the specification, work and price are agreed before anything is fitted.
- A technician [PROVIDER PACK: DBS check evidence] prepares the door where needed, fits the lock and runs it through a full cycle with the door both open and closed, so an alignment fault cannot strain a brand-new lock.
- You receive the keys and a record of what was fitted.

Lock Fitting Across Woking
We fit locks for homeowners, landlords, letting agents and business premises across Woking. Fitting is booked work; availability depends on your location, the door and the installation. [CLIENT TO CONFIRM: genuine coverage areas]
The housing mix shapes the work. Across the town, 29.4% of households live in flats, 27.3% in detached homes, 24.2% in semis and 19.0% in terraces (Census 2021 TS044, 30,440 households). On build age, 6.2% of homes predate 1900 and 16.1% date from 1900 to 1939, while 42.7% were built between 1945 and 1982, 22.4% between 1983 and 2008 and 11.8% since 2009 (VOA CTSOP 4.1, 31 Mar 2026). So there are older timber doors suited to mortice deadlocks, and many later doors where cylinder upgrades are the usual job. Around Mount Hermon there is a high share of flats and much private renting (Census 2021, output areas near Mount Hermon), so room locks, flat entrance doors and landlord approval come up often.
Woking has 14 conservation areas, among them Old Woking, The Hockering and Mount Hermon (planning.data.gov.uk, Oct 2026). No Article 4 direction affecting doors or windows is recorded there, though that dataset has gaps, so treat it as unknown rather than none. Conservation status can matter when replacing a whole door; it does not usually affect fitting a lock to the door you have.
We work across the GU21 and GU22 postcode districts (ONSPD Feb 2026), a built-up area of around 75,700 residents (Census 2021, ONS built-up area), including Mount Hermon, Knaphill and Horsell. From Woking we also serve three neighbouring towns, each with its own page: Sheerwater, New Haw and West Byfleet. See all areas we cover.

Frequently Asked Questions
How much does it cost to have a new lock fitted in Woking?
It depends on whether the door is already prepared or needs cutting, the lock and its security rating, the door material, how many doors are involved and when the work is done. Fitting where there is no existing provision takes longer than a swap. There is no call-out charge and the price is given on the call. [CLIENT TO CONFIRM: installation starting price, if one is to be published]
How do I know if my lock meets my insurance policy?
Look at the faceplate on the edge of the door for a British Standard kitemark and a BS number. On a uPVC or composite door, check the cylinder face for a star rating or Diamond mark. If you find no marking, the lock is unlikely to meet a policy that names a standard, and it is worth reading your policy wording and getting it checked.
I have a five-lever lock. Is that enough?
Not necessarily. Lever count alone does not confirm that a lock meets BS 3621. Many DIY-shop five-lever mortice locks carry no kitemark, and plenty of homes have them from earlier owners. Check the faceplate for the markings.
Can you fit a lock to a door that does not have one?
Usually, yes, provided the door and frame suit the lock proposed. The door is prepared first, typically by cutting a mortice pocket or boring for a cylinder, so the job takes longer than replacing an existing lock. The material, thickness, fitting position and use of the door are all considered before the lock is chosen, and sometimes an inspection is needed before the final specification is confirmed.
What is the difference between BS 3621 and BS 8621?
BS 3621 covers thief-resistant single-point lock assemblies operated by a key from both sides. BS 8621 covers thief-resistant single-point lock assemblies operated by a key from outside, with keyless exit from inside, which matters on escape routes such as flats and HMOs. PAS 3621 is the equivalent for multipoint systems on uPVC and composite doors.
Will you give me proof of what was fitted?
[CLIENT TO CONFIRM: itemised invoice naming lock, standard and doors] Once confirmed, you would receive an invoice naming the lock, the standard it meets and the doors it went on. Keep it with your policy documents, because an insurer may ask what was fitted if you ever claim.
Should I buy the lock myself and just pay you to fit it?
You can ask, and compatibility with the door is checked before anything is agreed. It is often a false economy: DIY-shop locks frequently turn out not to carry the standard a policy names. [CLIENT TO CONFIRM: policy on fitting customer-supplied locks and how the guarantee applies]
