A Locksmith for Your Home
L.M.N Locksmiths Lancing works on homes across Lancing, from an emergency lockout in the small hours to a booked lock change or security upgrade. Whatever has happened, the first question is which of these it is, and this page points you to the right answer quickly.
We answer 24 hours a day with no call-out charge. Locked out tonight: locked out. New to a property: lock replacement. A fault in a lock you already have: lock repair.
What Homeowners Are Actually Calling Us About
A homeowner in Lancing rarely needs a list of services; what helps is a short route from "this has happened" to the right page. The six moments below cover urgent access, faulty locks and planned security work.
You have been locked out
Whether the keys are indoors, the door has been pulled closed or the lock will not open, you may be unable to enter your home. You can expect an examination of the lock, followed by an appropriate non-destructive entry attempt as the first approach whenever the lock's type and condition permit.
Your keys are lost
Because lost keys may still operate the lock, losing them raises a security question. Fitting a replacement lock or cylinder takes those keys out of use.
Something has stopped working
Look out for a stiff key, a loose handle, a door that has shifted or a lock that no longer works as it should, and get it inspected before things deteriorate. Avoid forcing anything, as that can add damage. Lock repair → ·.
You have only just moved in
The number of copies made, and who still has them, is often unknown. New external door locks hand control of access to the people now living there.
Locks that feel out of date
Old, unsuitable or hard-to-use locks can be assessed on the doors or windows concerned, and the repair, replacement or installation routes explained. Lock installation → ·.
You were broken into
If anyone is in immediate danger, stay outside and phone 999. Damaged locks, doors and entry points can undergo assessment and be made secure once the police have confirmed that repair work may begin. Burglary repairs → ·.
The Things Homeowners Most Often Get Wrong
Homeowners are often reassured by a lock that looks tough, but appearance says little about wear, suitability or whether the lock suits the door. Consider these five common misunderstandings when assessing whether further checks, repairs or replacement may be needed.
Keys lost, not locked in.
Regaining entry may be enough to resolve the problem when keys are locked inside. Replacing the affected lock or cylinder is the only way to stop lost, unaccounted-for keys from continuing to open the property. Arrange a lock replacement → ·.
A uPVC door that will not lock.
Difficulty lifting the handle or locking it may come down to alignment, the cylinder or the multipoint mechanism, so the fault needs diagnosing before repair or replacement is chosen.
A safe chosen on looks.
Certification, the manufacturer's instructions and the installation may affect a safe's security performance or whether it meets an insurer's conditions; confirm those before picking the safe or its position.
Five levers taken as proof.
Lever count alone proves little, since a five-lever lock is not automatically a BS 3621 lock. Check for the British Standard number and certification marking, and then compare the lock with the security requirements in your insurance policy. BS 3621 explained →
Stiffness ignored.
A stiff key, a difficult handle or a door that needs force to lock may be a sign of misalignment, wear or a developing fault, and forcing it may cause further damage or leave the door unable to secure.
Your Home, Door-by-Door
The front door gets the attention, yet homes tend to be secured only to the standard of their weakest opening. Use the four checks below to find yours.
The front door
Normally your strongest door. Check the fit and the key action, then look for a British Standard mark on a timber door's lock faceplate or a rating on a uPVC or composite cylinder. BS 3621 explained →
Back and patio doors
Back, French and patio doors may be secured by a cylinder, a multipoint mechanism or other hardware. Because they are hidden from the street, they are often the doors that get used. A handle that is hard to lift, locking points that do not engage or a key that will not turn freely may indicate a door or mechanism needing attention. Arrange a lock repair → ·.
Windows to look at
Check that ground-floor and otherwise accessible windows close as they should, and that their locks and keys are available. Assess the fittings on your accessible windows using your policy wording, as security requirements for these windows appear in some insurance policies.
The side gate, garage and shed
Garages and sheds may contain valuable property, and an insecure side gate can give access towards the rear of the home.
Locksmith pricing
How Much Does a Home Locksmith Cost?
This is a hub page, so here are just the essentials; the price guide has the detail. The cost of a domestic job turns on the service, the lock type, the work required and the time of attendance. You get an expected price from the information you give before anyone travels, and you are not charged a call-out fee. Lockouts start from £70.80 including VAT for a standard job, Monday to Friday, 7am to 6pm. That starting price is for lockout work and does not cover repairs, replacement locks or other services. 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.
Any work found on inspection beyond your original description is explained, with its price, before you decide. Say on the call whether you own, rent or manage the address. The full Lancing locksmith price guide →
What affects the cost?
Service required, time of attendance, lock and door type, labour and parts.
Renting or Letting Out a Property?
This page is written for people who live in their homes, whether they own or rent, so here is how things differ if you are a tenant or a landlord.
As a tenant, try other doors or windows you can reach safely, then your landlord, agent or someone holding a spare key. Your landlord or agent may need to approve planned lock work. If you cannot get hold of them and still need a locksmith, we can help, and we will normally ask you to confirm that you live at the address before starting. Get help when locked out →
As a landlord or letting agent, you will find tenancy changeovers are the usual time for a lock change, and the work can be scheduled around that date, tenants and contractors. Keyed-alike cylinders mean one key holder can access several properties. Managed residential lets go through our landlord and HMO service; commercial premises go through our commercial locksmith service.

Frequently Asked Questions
What is the difference between a domestic and a commercial locksmith?
Homes fall under domestic work, and business properties fall under commercial work. For a house or flat, that includes trouble gaining access and locks on doors or windows. Commercial premises such as offices and shops may have different doors, locking systems and requirements for managing access.
Do I need to change the locks when I move house?
It is worth doing. There is no way to know how many keys exist for a home you have just bought or rented, or who still holds them: previous owners, tradespeople, letting agents and former tenants could all have copies. Replacing the external cylinders retires them all, and the price is agreed on the call, with no call-out charge.
Can you come out at night for a house lockout?
Yes, emergency help for a house lockout is available through the night, all year. Weekends and bank holidays are included. 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. If the door opens without damage to the lock, replacement is unnecessary and your keys still work. You receive the price over the phone before work proceeds.
Which part of my house is most likely to be the weak point?
For most houses, the back and patio doors or the accessible windows. They tend to have older hardware than the front door and are hidden from the road, which is precisely why they get targeted. A side gate that can be opened adds privacy for anyone at the rear, and garages and sheds are easy to forget entirely.
I rent. Should I call you or my landlord?
Work through it in order. First try any other door or window you can reach safely. Then contact your landlord, letting agent or anyone else with a spare key, as they can often let you in at no cost. If none of them can help, call us and we can open the door; we will normally ask for proof that you live there.
How can I tell if my locks meet my insurance policy?
Through its markings. On timber doors the faceplate along the edge should carry a British Standard kitemark and number, and on uPVC or composite doors the face of the euro cylinder should show any star rating or Diamond mark. A plain, unmarked lock is unlikely to meet the standard. Once you know what is fitted, check it against the requirements in your policy.
Do you fit burglar alarms or CCTV?
Not those, no. Our trade is locks and the things they protect: doors, windows, safes and their securing hardware. Electronic alarms and camera systems are fitted by a different trade, and we would sooner be honest about that than take the job on. If the concern is how well your openings keep people out, that is squarely our work.
Can you look at the whole house rather than just one door?
Yes. A whole-house look is often more useful than fixing one door in isolation, because locks installed together tend to reach the end of their life together. Covering all the openings in a single visit avoids several call-outs, and we will be honest about which locks need attention now and which are fine for the time being.
