Advice from BMS Locksmiths

Advice & FAQ.
A few answers
before you call.

A lock that won’t turn is rarely convenient. Whether you’re outside the front door or planning a replacement, these answers explain what to tell us, what we’ll check and how to choose the next step.

Based in Shepherd’s Bush · West London and surrounding areas

Questions / 01

Locked out & urgent help.

The first things to tell us: where you are, whether you can get in and whether the property can be secured.

Are you available 24/7?

Yes, we offer 24/7 emergency callouts. Call with your full postcode and tell us what has happened, so we can confirm availability and an estimated arrival time.

How quickly can you get to me?

We give an estimated arrival time when you call. Your address, traffic and current jobs all affect the journey. We’re based in Shepherd’s Bush and cover West London and selected surrounding areas; there is no fixed arrival time for every callout.

What documents do I need for emergency door opening?

We ask for identification and evidence that you are entitled to access the property before opening it. If your documents are locked inside, tell us when you call so we can discuss how access can be verified. Knowing what is inside the property is not enough on its own.

Will opening the lock damage my door?

We aim to use a non-destructive method where the lock and circumstances allow it. Some faults or lock types need a different approach. We assess the options and explain any work that may involve drilling or replacement before proceeding; damage-free entry cannot be promised for every job.

Questions / 02

Booking, prices & payment.

A clear description helps us discuss the work and the likely cost before you book.

Are your locksmiths DBS checked?

Yes, our locksmiths are DBS checked. If you have particular requirements for a managed property, workplace or care visit, mention them when booking.

Do you charge a call-out fee?

We don’t add hidden call-out charges. We explain the charges for the work and parts before starting. Ask what the estimate includes, and let us know if the job changes. Our price guide is a starting point; the cost depends on the work needed.

How can I pay, and will I receive a receipt?

We accept cash, cards, bank transfers and payments over the phone. We can send your receipt by SMS or email. Tell us before the visit if you need particular invoice details for a business or managed property.

Do you work with businesses as well as homes?

Yes. We work on homes, shops, offices and managed properties, including landlords’ communal areas. See our residential services and commercial services, or tell us about the property and the job.

Do you cover my postcode?

We cover the 26 areas listed on our Areas We Cover page, including West London, Hounslow, Staines-upon-Thames and Windsor. Call with your complete postcode to confirm availability for the address. If your area is not listed, ask us before booking.

Questions / 03

Locks, keys & repairs.

The same symptom can have more than one cause. A photo of the lock and the edge of the door is often useful.

What is the difference between a night latch and a mortice lock?

A night latch usually has a lock case on the inside face of the door and a latch that catches when the door closes. A mortice lock sits in a recess cut into the edge of the door; a mortice deadlock has a bolt operated by a key. The suitable combination depends on the door and your requirements, rather than every property needing the same arrangement.

My uPVC door handle is stuck. Can you fix it?

We repair and replace faulty uPVC locks, mechanisms and handles. A stuck handle can be caused by alignment, the gearbox or another part of the mechanism, so it needs checking. Don’t force the handle or key. Tell us whether the door is open or closed and whether it can be locked. Read more about multipoint door locks.

Which brands of locks do you work with?

Our work includes brands such as Yale, Chubb, Union, ERA, APECS, Ultion, EVVA, Banham and Mul-T-Lock. The choice depends on the existing fitting and what you need from the door. We discuss suitable options and availability before installation; see examples in our work gallery.

I’ve lost my keys. Does the whole lock need replacing?

Not always. Depending on the lock, changing the cylinder or replacing or reconfiguring suitable internal components may provide a new set of keys while retaining other fittings. We check what is possible and make sure you understand which keys will work afterwards.

Can you remove a key that has snapped in the lock?

We can assess the lock and use extraction tools where appropriate. Avoid pushing another key or tool into the keyway, as this may make removal harder. Tell us whether the door is locked and whether any part of the broken key is visible. A damaged lock may also need repair or replacement.

What does BS 3621 mean, and how can I recognise it?

BS 3621 is a British Standard associated with thief-resistant, key-operated locks. On a certified lock, look for the BSI Kitemark and the standard number, often on the faceplate at the edge of the door. A brand name or a five-lever description alone does not establish that a lock meets BS 3621. If you’re unsure, send a photo and any requirements from your insurer.

Should I ask about an anti-snap cylinder?

If your door uses a euro cylinder, ask about a suitable tested replacement, such as a three-star TS 007 cylinder. The size, fitting and door hardware matter too. We can discuss the options for your door; no lock makes a property burglar-proof. See our lock fitting guidance.

Questions / 04

Planning & home security.

Start with the door, the people who use it and any specific requirements you need to meet.

Can you assess the security of my home?

Yes. We can look at the existing locks and fittings with you and discuss practical changes. Tell us about any troublesome doors, lost keys or access arrangements you want to change. A locksmith visit does not replace advice from your insurer or a formal fire-safety assessment where one is needed.

How do I know whether my locks meet my insurance requirements?

Check your policy wording or ask your insurer which specification applies to each door or window. Requirements differ, and “insurance-approved” is not a universal label for every lock. Send us the wording and a photo of the existing fitting. We offer British Standard locks where appropriate and other suitable options agreed with you; your insurer decides whether a particular arrangement meets the policy.

Should I change the locks when I move in?

It is sensible to review who may still have working keys. Changing suitable locks or cylinders can give you control of the new set. If you rent, check the arrangements with your landlord or managing agent before booking alterations.

Can one key open more than one of my doors?

Yes, compatible locks can sometimes be supplied keyed alike, so one key operates them. This is different from a master key suite, which can give different users access to different doors. Tell us which doors are involved and who needs access so we can check the options.

Small checks, worth making

Around the house.

A few everyday checks for doors, keys and the parts of the property that are easy to overlook.

01

Choose the lock for the door

Check any requirements in your insurance policy before choosing a replacement. If the door uses a euro cylinder, ask about suitable tested anti-snap options. Agree the product before fitting.

02

Keep track of working keys

Review spare keys when you move home or change a tenancy. For several doors, ask whether compatible keyed-alike locks could simplify access without giving everyone more access than they need.

03

Look beyond the lock

Check the condition of the door, frame and accessible windows. A suitable reinforcement bar may be worth discussing on a timber door. Use fitted window locks when securing the property.

04

Keep keys out of reach

Keep house and car keys away from doors, windows and letterboxes. Ask about a suitable letterbox guard. For keyless car fobs, a signal-blocking pouch may help; test that it works with your vehicle.

05

Remember gates and outbuildings

Check side gates, sheds and garages as well as the front door. Use locks and padlocks suited to the fitting and outdoor conditions, and keep valuable tools and bikes secured.

06

Consider the approach to your home

Suitable lighting and clear sightlines can help around entrances. Gravel can make footsteps more noticeable, but it is an extra measure, not a replacement for sound doors and locks.

07

Before you go away

Check doors and windows before leaving, arrange for someone you trust to keep an eye on the property and avoid public posts that advertise an empty home. Keep spare keys with a trusted person rather than outside.

08

Don’t force a stiff lock

If the key or handle becomes difficult to operate, stop forcing it. Use only maintenance products recommended for that particular lock, or have the fault checked. A stiff handle is not always a lubrication problem.
