Locked out or lost your keys
Start here if something has already gone wrong. These guides tell you what to check before you pay anyone.
Locked out of your flat in London
Whether a slammed door is latched or deadlocked, who to ask first in a mansion block, and when the porter, landlord or a locksmith is the right call.
Lost your house keys in Chelsea
Why it matters if the keys were lost with something showing your address, who to tell, and when a lock change is worth it.
Lost a Banham key
How Banham registered keys work, why only Banham can cut them, and the choices you have if you need to get in tonight.
If you would rather have someone come out, go straight to house and flat lockouts in Chelsea.
Choosing the right lock for your door
An old or badly fitted lock is often an easier way in than a window. These guides help you choose before you buy.
- How to choose the best door lock for a Chelsea home: matching the lock to the door, whether timber, uPVC or composite, and to your insurance terms.
- The three most common door locks in Chelsea homes: how to tell a nightlatch, a mortice deadlock and a euro cylinder apart, and what each one is good and bad at.
- BS3621 locks and home insurance: what the kitemark on the faceplate means and why many policies ask for it on final exit doors.
- Why uPVC door locks fail: dropped doors, worn gearboxes and the early warning signs before the handle stops working.
- Practical ways to make your home safer: cheap, sensible changes to doors, sash windows, lightwells and garden gates.
Once you know what you want, our anti snap cylinder fitting and same day lock change pages explain the work and price.
Advice for car owners
Keyless car theft in Chelsea explains why cars with keyless entry are targeted on residential streets and the simple habits that make yours harder to take, such as storing keys away from the front door in a signal blocking pouch and using a steering lock. If you have already lost a key, our car key replacement service makes a new one at the car; call with your registration so we can confirm your make and model first.
Avoiding rogue locksmiths
Locksmith scams in Chelsea lists the warning signs: a vague price on the phone, a different person turning up from the one you spoke to, and a lock drilled before anyone tried to open it without damage. Read it before you need it, then keep a local number in your phone.
How we handle it
We agree the price before we travel, try non destructive entry first and show ID at the door. Our published locksmith prices are the same ones we quote on the phone.

Common questions
Where can I get free locksmith advice in Chelsea?
The guides on this page are free to read, and you can ring 07520 643913 or send a photo of your lock on WhatsApp to ask a quick question. We will tell you honestly if you do not need a locksmith at all.
What is the most secure front door lock for a London home?
It depends on the door. Period timber doors are best served by a British Standard nightlatch with a BS3621 mortice deadlock; uPVC and composite doors need a TS007 3 star or Sold Secure SS312 Diamond anti snap cylinder. Our guide to choosing a lock covers both.
Should I change the locks when I move house?
Usually yes, because you cannot know how many keys the previous owners, tenants, cleaners or builders still hold. On most doors changing the cylinder or lock is a quick job and costs far less than a burglary claim.
How can I tell if a locksmith is genuine?
A genuine local locksmith gives a clear price before travelling, names the business, shows ID at the door and tries non destructive entry first. Be wary of anyone who quotes vaguely or starts drilling straight away.
Do you write guides about cars as well as homes?
Yes. Our keyless car theft guide covers protecting cars parked on Chelsea streets, and our car locksmith pages explain lockouts and replacement keys, including when a model has to go back to the dealer.
