Smart Locks

Smart Locks near you

A smart lock has to fit a British door, and that is where most of the decision lies. A uPVC or composite front door locks with a multipoint mechanism driven by a euro cylinder, so the smart version is usually a motorised cylinder or a smart handle set working the same strip of bolts. A timber door on an older terrace, with a nightlatch above a mortice lock, is a different problem again, and the communal entrance of a converted flat is not yours to change at all. Measuring the cylinder, watching how the door sits in its frame and reading the lease all come before any comparison of apps.

The lock itself is now a regulated product. The consumer connectable product security regime made under the Product Security and Telecommunications Infrastructure Act 2022 came into force on 29 April 2024, and the government's own list of products in scope includes connected door locks. It sets a floor rather than a ceiling: no universal default password, a published route for reporting security problems, and a published minimum period during which security updates will be provided.

Fitting one is not licensed work in the United Kingdom, so there is no register to check and no certificate to ask for. That puts the weight on the door, the paperwork and the escape route instead. Anything that runs on mains electricity, such as an electric release or an access control panel on a shared entrance, is building work with its own rules rather than a consumer gadget.

Smart locks for British doors: motorised cylinders, retrofit units and smart handles

The type of smart lock that suits you is decided by the door you already have. Most disappointing installations start with a product chosen online and a door it was never designed for, so work the other way round: identify the lock currently doing the work, then find the smart version of that.

  • Motorised euro cylinders: replace the cylinder in a uPVC or composite door and drive the multipoint mechanism already fitted, leaving the door, frame and bolts untouched.
  • Retrofit thumbturn units: mount on the inside over an existing cylinder or nightlatch and turn it for you, so the outside of the door and the original keys stay exactly as they were.
  • Smart handle sets and keypads: replace the handle furniture on a multipoint door and add code or fingerprint entry, which does change the appearance of the door from the street.
  • Smart nightlatches: made for the timber front doors of older terraces, where a rim latch rather than a multipoint strip is what actually holds the door shut.
  • Key safes and code boxes: not locks, but the usual way carers, cleaners and holiday guests are let in, and best decided at the same time rather than bolted on afterwards.
  • Hardwired access control: an electric release or maglock on a shared entrance, which is mains-powered building work and a different conversation entirely.

No installer licence in the UK, but the lock is a regulated product

Start with what is not regulated. The activities that can be licensed in the private security industry are listed in Schedule 2 to the Private Security Industry Act 2001, and they are manned guarding, private investigations, security consultancy, key holding and door supervision at licensed premises. The government's guidance on whether you need an SIA licence lists manned guarding, key holding and vehicle immobilisation in Northern Ireland. Fitting or maintaining a lock is in neither list, so nobody licenses the person who comes to your door.

The product is a different story, and this is the part most householders have never heard of. The Product Security and Telecommunications Infrastructure (Security Requirements for Relevant Connectable Products) Regulations 2023 came into force on 29 April 2024 and extend to England and Wales, Scotland and Northern Ireland. Section 4 of the 2022 Act defines a relevant connectable product as one that is internet-connectable or network-connectable and is not an excepted product; Schedule 3 to the Regulations lists the exceptions, which include electric vehicle charge points, medical devices, smart meter products and ordinary desktop computers, laptops and tablets without cellular connectivity. A smart lock is none of those.

One adjacent activity is licensed, and it is worth separating from the rest. Paragraph 6 of Schedule 2 covers keeping custody of, or controlling access to, any key or similar device for operating a lock. If a company is going to hold a code or a key to your home and attend when something happens, ask about that part specifically, even though nobody needed a licence to fit the hardware.

  • Passwords must be unique per product or capable of being defined by the user, and a unique password must not be based on incremental counters or on publicly available information, or otherwise be guessable in a way good industry practice would not accept.
  • The manufacturer must publish at least one point of contact for reporting security issues, along with when you will get an acknowledgement and status updates until the issue is resolved.
  • The defined support period - the minimum length of time security updates will be provided - must be published, and it cannot be shortened afterwards.
  • The product must be accompanied by a statement of compliance, which section 9 of the Act requires before a manufacturer may make it available in the UK, and which may be digital rather than a piece of paper.
  • The Office for Product Safety and Standards enforces the regime, using tools including compliance notices, stop notices and recall notices.

What a smart lock installation should actually involve

A good fitter measures before recommending anything. On a multipoint door that means the cylinder size taken from both sides of the centre screw, how far the cylinder sits proud of the handle, whether the handle has to be lifted to throw the bolts, and whether the door needs a shove on a warm day. A motor asked to drive a mechanism that a person has to fight will chew through batteries and then fail, usually with the door locked.

Setup is the half that gets rushed. Before anyone leaves, the account should be in your name with your own password, household members should be added as their own users rather than sharing one login, the mechanical override should have been tried from outside, and you should have watched the lock work from both sides. Ask for the model number, the app it depends on and the published support period to be written down; you will want all three the day something stops working.

LokalMatch is only the introduction. You describe the door, the lock currently on it and what you want to be able to do, once, with your postcode, and installers who cover your area get in touch with you directly; the pros pay for the requests they receive. LokalMatch does not fit locks, does not attend, does not set prices, and does not vet, rank or recommend any of the businesses that reply, so the measuring and handover questions above stay yours to put to each of them.

The account now opens your front door: securing it properly

A smart lock moves part of your front door security onto a phone and a server. The National Cyber Security Centre's advice for households is short and worth following exactly, because most of the trouble with connected devices comes from defaults nobody changed rather than from clever attacks.

  • Change any password the device arrived with, and make the replacement a secure one - the NCSC suggests combining three random words you will remember.
  • Turn on two-step verification if the app offers it; the NCSC's position is that any two-step verification is better than none, and that it means a criminal who knows your password still cannot get in.
  • Switch off remote access if you do not need to reach the lock from outside your home network.
  • Switch on automatic updates where they are available, and install manual updates when prompted.
  • Check the manufacturer still supports the model before you buy, since the NCSC advises avoiding devices that are no longer supported.
  • If you ever think someone else has taken control of a device, reset it using the manufacturer's own instructions, and factory reset any lock before you pass it on or leave it behind.

Getting out: escape routes, flat batteries and communal doors

Security and escape pull in opposite directions, and escape wins. Government fire safety guidance for the home is to plan an escape route and make sure everyone knows how to escape, to keep exits clear, and to keep door and window keys where everyone can find them. A smart lock should make that easier, not harder: everyone in the household, including children, visitors and anyone with limited hand strength, has to be able to open the door from inside immediately, in the dark, without a phone or a code.

Then plan for the flat battery, because it will happen on the coldest morning of the year. Know where the mechanical override is and carry the key it needs, keep a spare with a person rather than under a plant pot, and replace batteries on a schedule rather than on a warning. If the lock depends on your broadband or the manufacturer's servers, find out before you buy what still works when both are down.

If you rent or own a leasehold flat, ask before you drill. A tenancy usually says something about altering locks, a lease will say something about altering the front door of the flat and almost certainly about the communal entrance, and a managing agent will have a view on anything fixed to a shared door. Keep the original hardware so it can go back when you leave.

Codes, users and the support period: keeping a smart lock honest

  • Give each person their own code or login rather than a shared one, so removing someone's access does not mean changing everyone's.
  • Delete codes and users when a cleaner, a builder, a lodger or a former partner no longer needs access, and change the master code once the installation is finished.
  • Set temporary codes to expire by themselves rather than relying on your memory to withdraw them.
  • Note the published support period somewhere you will find it again, and plan to replace the lock rather than run it unsupported once that period ends.
  • Keep the mechanical cylinder in use occasionally so it does not seize, and lubricate it with a proper lock lubricant rather than a general-purpose spray.
  • Have the door itself checked when it starts needing a lift or a shove, since the mechanism, not the electronics, is what usually fails first.

Your rights when the lock, or the app behind it, lets you down

A smart lock is three purchases at once, and consumer law treats them separately. Under section 9 of the Consumer Rights Act 2015, every contract to supply goods is treated as including a term that the quality of the goods is satisfactory, and quality expressly includes fitness for the purposes goods of that kind are usually supplied for, freedom from minor defects, safety and durability. The app and its cloud service are digital content, and section 34 applies the same satisfactory quality standard to them, again including safety and durability.

The fitting is a service, and section 49 treats every contract to supply a service as including a term that the trader must perform it with reasonable care and skill. Between them, those three provisions cover the lock that fails in a year, the app that is withdrawn, and the door that was never adjusted. The published support period is the piece of evidence that ties them together, which is a good reason to keep a copy of it from the day you buy.

Smart Locks: frequently asked questions

Do I need a licensed installer to fit a smart lock in the UK?

No. Installing or maintaining locks is not among the activities liable to control in Schedule 2 to the Private Security Industry Act 2001, and the government's guidance on who needs an SIA licence covers manned guarding, key holding and vehicle immobilisation in Northern Ireland rather than installation work. Any badge you are shown is a trade membership, not a government licence, and it is fair to ask which it is.

How do I know a smart lock will keep getting security updates?

Because it now has to tell you. Under the security requirements that came into force on 29 April 2024, the defined support period has to be published, and it cannot be shortened once it has been. Look for it before you buy, not after, and treat a product that makes it hard to find as a product that is telling you something.

Can I fit a smart lock on a rented home or a leasehold flat?

Ask first. A tenancy agreement usually says something about altering locks, and a lease will normally cover changes to the flat entrance door and certainly to the communal entrance. A retrofit unit that sits on the inside of the existing lock changes nothing visible and comes off when you leave, which is often the easiest thing to get agreed. Keep the original hardware either way.

What happens when the batteries die while I am out?

Use the mechanical override, which is why you should be carrying the key it needs rather than keeping it inside the house. Most locks warn well in advance through the app or a sound, so replace batteries on a schedule instead. Before buying, check what the lock does when the batteries, your broadband and the manufacturer's servers are each unavailable.

Is a smart lock a fire risk?

It should not be, but it is worth designing around. Government fire safety guidance is to plan an escape route, keep exits clear and keep door and window keys where everyone can find them. Choose a lock that opens from the inside by hand without a code or a phone, make sure every member of the household can work it in the dark, and avoid settings that require anything at all to get out.

What affects the cost of smart lock

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Number of cameras, sensors or devices
  • Wired or wireless installation
  • Monitoring and subscription fees
  • Running cables through finished walls or ceilings
  • Size and layout of the home
  • Integration with other smart home or network equipment

How to compare smart lock installers before you hire

  • Choose an installer who looks at your home in person and explains where cameras, sensors or access points should go.
  • Ask whether monitoring is included, whether it's optional and what the contract length and cancellation terms are.
  • Find out whether you'll own the equipment or lease it, and whether it works with other systems.
  • For hardwired systems, make sure any electrical work is done by a licensed electrician.
  • Ask how they'll set up passwords, apps and network security, and make sure you get the admin access.

Questions to ask smart lock installers before you hire

  • Will I own the equipment, or is it leased or tied to a contract?
  • Is monitoring required, and what are the cancellation terms?
  • Where will the cameras point, and will they capture my neighbours' property?
  • Who will have access to the video and the account?
  • Will this work with my existing Wi-Fi, locks or smart home devices?
  • What warranty covers the equipment and the installation?

Smart lock permits and local rules

Some smart lock work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
