Need a Door Lock Replaced in Hastings?
Yes: B.T Locksmiths Hastings supplies and fits replacement locks for front doors, back doors, internal doors and communal entrances across Hastings, usually in a single visit. There is no call-out charge, and the price is agreed before work starts.
People usually come for one of three reasons. They have moved into a new home and cannot know who holds keys. Keys have been lost or stolen. Or the lock has worn out or been damaged. If a door will not secure tonight, an emergency lock replacement can be arranged.
What Part of the Lock Actually Needs Replacing?
"The lock" is rarely one single thing: on most doors the word covers a handful of distinct components. If only one of them has failed, the rest of the system may well be fine.
The barrel or cylinder
The barrel is the component your key slides into and operates. Here, a euro cylinder is fitted to the majority of uPVC, composite and aluminium doors. Fitting a new barrel hands you fresh keys without disturbing the mechanism behind it or the handles. Thumb-turn and keyed-alike versions may be possible too, depending on the door and the product you pick.
The lock mechanism or case
The lock case is where the working parts live, inside the door itself. A mortice lock case may be fitted within a timber door. On uPVC and composite doors, the equivalent may be a gearbox linked to a multipoint locking strip. Changing that internal mechanism is a bigger task than a cylinder swap, and it can be the right answer when the working parts have given up but the cylinder still does its job.
The lockset as a whole
Sometimes the cylinder, mechanism, handles and associated fittings are all replaced together. That route may suit a door where several parts are damaged, where matching parts are no longer available, or where security needs upgrading.
Identifying the failed part before anything is swapped means serviceable, secure components are not replaced for the sake of it. Related pages: uPVC door locks and.
Hastings Homes and Businesses: Lock Types Found
Your front, back and bathroom doors probably use three different systems, so the door, its hardware and the failed component decide the replacement.
A nightlatch
Many timber doors have a nightlatch on their inner face, nicknamed a "Yale lock" although Yale is a brand, not every nightlatch. Condition allowing, the rim cylinder may be changed separately.
A mortice lock
A mortice lock is cut into a timber door's edge, so the full case lives inside the door. Some timber final-exit doors are fitted with five-lever mortice locks certified to BS 3621. Because the standard an insurer wants can vary, check your policy.
A euro cylinder
The norm on uPVC, composite and aluminium doors, a replacement euro cylinder delivers new keys while the rest of the mechanism stays. It has to be the right size, as excessive projection can cut security. Keyed-alike and thumb-turn choices may exist for some doors and products.
The locks of composite doors
A composite door commonly runs a euro cylinder with a multipoint mechanism, and the cylinder may be replaceable without the longer mechanism. Hardware, dimensions and the failed part govern the right choice.
A multipoint mechanism
This long locking strip inside a uPVC or composite door edge holds the door at several points. Changing the whole mechanism is more involved than changing its cylinder and needs compatible hardware.
Internal door locks
Mortice latches, sashlocks and privacy locks are common on internal timber doors; the room's use and the need for a key, handle or privacy function decide which.
Replace a Lock Rather Than Repair It: When Should You?
Should you replace or repair? The honest answer is that a faulty lock does not always need replacing, and a repair, adjustment or minor component change can sometimes get it working reliably again. Before recommending either, we assess the lock and the door, because the choice turns on the failed component, the scale of any damage and whether the lock remains secure.
Usually, replacement is the right call
Replacement tends to be right when keys have gone missing or been stolen and are unaccounted for, or when you have moved into a new home and want earlier keys shut out. It also fits where inspection shows the cylinder or internal parts are worn beyond a dependable repair, where forced entry has damaged the lock past fixing, or where your insurer specifies a lock standard the current one does not meet. You receive new keys when either the key-operated cylinder or the entire keyed lock is replaced.
Repair is often enough here
Repair is worth considering if the lock behaves with the door open but resists once it closes, if the handle is loose while the mechanism still operates, if the key is stiff but the cylinder proves serviceable, or if the door has dropped and no longer meets the frame properly. These can indicate alignment, handle or repair problems rather than a full replacement, though inspection is still needed to identify the cause.
Replacing Locks After Lost or Stolen Keys
Should you replace the lock after losing your keys? Sometimes, not always. The decision rests on where they were lost, whether they were taken deliberately and whether whoever has them could work out your address.
Here is the risk in plain terms: keys you cannot account for may still unlock your door. A fresh copy cut from a spare restores your access, but it does not prevent the lost keys from working the lock you already have. For a door with a separate, replaceable cylinder, the work required may be limited to changing that cylinder. All keys for the old cylinder become useless, a new set comes with the replacement, and the handles and other serviceable hardware are left as they are, which keeps the job proportionate.
Which Security Standards Your Insurer May Expect
Insurers do not all ask for the same thing. Some home insurance policies specify the type or security standard of lock on external doors, and requirements vary by insurer, policy and door type, which is why your own policy wording, or a quick question to your insurer, should come before choosing a replacement.
BS 3621 on timber doors
A policy may specify a mortice lock or nightlatch certified to BS 3621 for a suitable timber final-exit door. A five-lever lock is not automatically BS 3621 certified, so the standard marking needs checking.
Anti-snap ratings on euro cylinders
Euro cylinders are used on many uPVC, composite and aluminium doors. TS 007 3-star and SS312 Diamond are among the recognised anti-snap ratings, and the best option depends on the existing door, handles and locking system.
The limits of "insurance approved"
Every insurer does not accept the same lock just because it is labelled insurance approved. The insurer determines the requirements of its individual policy; certification establishes that a product meets a recognised security standard. We can identify the existing lock and its visible security markings, while your insurer should confirm whether that standard satisfies your policy conditions. Read our guides on BS 3621 door locks and anti-snap door locks.
After Moving Into a New Home: Changing the Locks
It is worth reviewing who can access a property as soon as it becomes yours. Keys tend to multiply over time, and when you take over a new home you cannot know how many copies exist, nor whether a previous owner, an old tenant, a letting agent or a contractor still keeps one.
New external cylinders resolve that. They render the existing keys useless and give you sole control over the replacement set. Where several doors are fitted with compatible locks, keyed-alike cylinders may be possible, so one key can operate a number of entrances. Many people moving house never realise that option exists, and it turns a security job into a genuine everyday convenience, particularly when the front door, back door and any other external door are all done together.

The Cost of a Lock Replacement: What Affects It
Lock replacement prices depend on the job, which is why we ask a few questions first and then give you a price on the call. You are not charged for the call-out, whenever you ring. Here is what we will want to know:
- What needs replacing: the cylinder, the case or the full mechanism?
- Which security rating would you like the replacement to have?
- What type of door is it?
- How many doors are involved?
- What time of day do you need the work?
Each answer affects the figure you are quoted.
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.
What affects the cost?
Service required, time of attendance, lock and door type, labour and parts.

Frequently Asked Questions
Do I need a whole new lock or just a new barrel?
A new barrel is normally enough. The barrel is the euro cylinder on most uPVC, composite and aluminium doors, and fitting a replacement gives you a fully working lock plus a new set of keys, while the mechanism inside stays put. Only when that internal gearbox or lock case has failed does the whole mechanism need replacing, which is a less common and more involved job. Our quote comes from your description on the call and holds unless the job differs on site; we explain any change before starting work.
How long does it take to replace a door lock?
The time depends on the type of lock and the work needed. Swapping a cylinder is usually a smaller task than replacing a mortice lock case or a multipoint mechanism. The door's condition also matters, along with whether a compatible replacement is available. The likely time can be explained after the lock has been inspected.
Should I change the locks when I move house?
It is worth doing: you cannot know how many keys exist or who still holds them, from previous owners to tradespeople, agents and former tenants. Replacing the external cylinders puts every key back in your hands. Hastings has 16 conservation areas, among them Hastings Town Centre, Cornwallis Gardens, St Leonards North and Warrior Square (planning.data.gov.uk, October 2026). That affects replacing a door, not the lock in it, and the national dataset does not say whether any Article 4 direction restricts doors or windows, so ask the council before changing a door.
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?
That comes down to what your policy says. Some home insurance policies specify a British Standard BS 3621 lock for timber final-exit doors, or a suitably rated cylinder for uPVC and composite doors. Insurers, door types and policies all differ, so read the wording or ask your insurer. A product being called "insurance approved" only means it meets a certified standard; your insurer decides what counts.
What is an anti-snap lock and do I need one?
Put simply, it is a cylinder designed to resist snapping, where the barrel is broken in two to force entry. TS 007 3-star and SS312 Diamond are recognised UK ratings for this. You may or may not need one, depending on your door and your insurer, but on a uPVC or composite front door it is a worthwhile upgrade that can be fitted as part of a routine cylinder replacement.
How much does it cost to replace a door lock in Hastings?
It depends on the part, the security rating, the door, how many doors and the time of day. A cylinder is the least expensive job and a full multipoint mechanism the most. Age matters: 34.9% of Hastings homes were built before 1900, 15.6% from 1900 to 1939 and 28.2% from 1945 to 1982 (VOA council tax property stock, 31 March 2026), and older timber doors often have mortice locks. There is no call-out charge, and you hear the price before work.
Can you replace locks on a rental property between tenancies?
Yes. Changing external cylinders between tenants is routine and can be booked around a changeover date instead of being treated as urgent. In Hastings 28.5% of households rent privately and 14.2% from a social landlord, against 56.8% who own (Census 2021, ONS), so many homes change hands between tenants. Landlords and letting agents with several properties can arrange work across multiple addresses. Tenants should check their tenancy agreement before changing a lock themselves.
