Yale: Locks, Alarms and Doorbells for a UK Home

Yale has been making locks for UK households since 1840, and today it makes three things that matter to a household getting ready for trouble: door cylinders, a smart alarm and a smart video doorbell. The cylinder is the one to think about first. Police advice is that a euro cylinder on a front door should meet TS007 3 star or the Sold Secure Diamond Standard, because those ratings are tested against snapping, drilling and bumping¹. If your door has a cylinder with no stars on its face, or one that sticks out past the handle, that is the job to do this weekend.

The alarm and the doorbell are about knowing what is happening at your door and in your home when you are in it, asleep, or away. They run on mains power and a home network, so they are not the kit that gets you through a power cut. What they do is make the ordinary weeks safer, which is most of what preparedness is.

This page sets out what each piece of Yale kit does, how it fits a household plan, and how to get support. For the wider picture, start with our Home Security: A Household Guide.

Over 185 years of locks for UK households

Yale's history runs back to 1840, which means generations of British households have had the name on a lock, a padlock or a night latch. That longevity is worth something in a market where locks are bought rarely and usually in a hurry, but it is not the reason to choose one lock over another. The reason is the standard the lock is built and tested to.

Doors are also where a lot of ordinary domestic injury happens. Local authority safety guidance records more than 200,000 injuries a year through collisions and entrapments involving doors in dwellings⁵. A door that closes properly, with a handle that works and a lock that turns without forcing, is a safety item as well as a security one.

For a household thinking about emergencies, the front door is the one piece of security kit you will use every single day, in every kind of incident. It is what you lock behind you when you leave for a rest centre, what you check last thing at night during a storm, and what you want to hold firm if a power cut takes out the street lighting. Getting it right once, and knowing how to check it, is a better use of an afternoon than most purchases.

Where you live changes who to ask for advice. Police crime prevention advice on door and window locks is published by each force, and the four nations each run their own policing structures, so the force covering your address is the one to read. The standards themselves, TS007 and Sold Secure, are UK-wide.

What Yale makes for securing a UK home

Yale's household security range divides into three jobs. The cylinder is the lock itself, the part a burglar attacks. The alarm is the thing that tells you, and makes a noise, when someone is where they should not be. The doorbell is the thing that lets you see and speak to whoever is at the door before you open it.

Two things follow from that table. First, only the cylinder is passive: it works whether or not there is power, a network or a phone in the house. Second, the alarm and doorbell are conveniences that depend on infrastructure, so they belong in the "ordinary weeks" part of your planning, not the "grid is down" part. For the kit that carries a household through an outage, see our Emergency Kit: What a UK Household Should Keep Ready.

Door cylinders: the TS007 3 Star rating

The cylinder is the barrel the key goes into. On most modern UK front doors it is a euro cylinder, and it is the weakest point on an otherwise solid door. Police advice is direct: if you have euro-cylinder locks, they should meet TS007 (3 star rating) or the Sold Secure Diamond Standard¹.

A 3 star TS007 cylinder is tested against the common ways a burglar defeats a lock. Police guidance lists lock snapping, drilling and bumping among them². The star rating is a shorthand for how much of that the cylinder is built to survive, and it is marked on the face of the cylinder so you can check it yourself without tools.

Yale's own cylinder in this class is the Fortress 3 Star. Its datasheet gives the full picture of what has been tested³:

• Approved by Sold Secure Diamond
• BS Kitemark to BS EN 1303:2015
• TS007-1:2014 3 star
• BSI Kitemark Licence No. 553031
• Classification 1 6 0 0 0 C 6 2
• Fire tested in accordance with EN1634-1 for 30 minutes and 60 minutes

That fire test matters more than it looks. A front door is a fire door in many flats and houses, and a cylinder that has been tested as part of a fire-resisting door assembly is one less unknown in a fire. If you live in a flat, check with your building's management before changing any door hardware, because fire door specifications are not yours to alter unilaterally.

Why snap-resistant cylinders matter for your front door

Lock snapping is a physical attack: the cylinder is broken at its weakest point so the lock can be turned from outside. It is quick, quiet and needs no key, which is why the standard exists. A 3 star cylinder is built so that this attack fails, and so that drilling and bumping fail too².

Yale describes how its Fortress 3 Star cylinder behaves under attack: if attacked, a security pin automatically triggers, blocking the cylinder cam and preventing unlawful entry, and the cylinder can still be operated from the inside with a key³. That last part is the point for a household. In a fire, or when you need to get out in a hurry, the door still opens from inside.

There is one installation condition that decides whether any of this works. On all double cylinders where the dimensions are equal on both sides, the maker states that the security protection is only on the external (O) side, and the cylinder must be installed so the external side marked O is visible from outside the door³. Fit it the wrong way round and the protection is on the inside, where it does nothing.

Older doors need a different fix. Police advice for older patio, sliding or bi-fold aluminium doors is that if the cylinder lock protrudes beyond the frame handle, you should get a member of the Master Locksmiths Association to change it to a shorter, more snap-resistant one⁶. Protruding cylinders are the ones that can be gripped and snapped.

Total Trust Guarantee: what it covers on the TS007 3 Star Cylinder

Yale backs its TS007 3 Star Cylinder with the Total Trust Guarantee. The guarantee is tied to that cylinder, so if you are buying a lock and want the cover, that is the model to specify. Keep the receipt and the packaging: a guarantee claim is a paperwork exercise, and the household that kept the paperwork is the one that gets a replacement.

Yale's datasheet for the Fortress 3 Star cylinder separately states a 10 year mechanical guarantee³. The two documents describe cover in different terms, so read whichever comes with the cylinder you actually buy and keep it with the receipt. If you are unsure which applies, ask Yale's support team before you buy rather than after.

What a guarantee does not do is stop the door being attacked. It covers the product, not the household, and it does not replace home insurance. Treat it as a sign that the maker expects the cylinder to last, and as a reason to keep the paperwork in the same folder as your other home documents.

Where the guarantee does not apply

A guarantee is a promise about a product used as intended, and the conditions matter as much as the cover. Three things will take a household outside it.

• Wrong orientation. On equal-sided double cylinders, the maker states the protection is only on the external side marked O, and the cylinder must be installed with that side facing out³. Fitted the other way round, the cylinder is not doing what it was sold to do.
• Wrong door or wrong fitting. A cylinder fitted to a door it was not made for, or fitted badly, is not a product fault. Police advice is to use a Master Locksmiths Association member for older aluminium doors where the cylinder protrudes⁶, and the same logic applies to any door you are unsure of.
• Lost paperwork. Without proof of purchase and the model, a claim has nothing to stand on.

There is a wider point for a preparedness page. A guarantee is not a plan. If your door is forced, the guarantee does not get you a locksmith at midnight, a secure door before bed, or a conversation with your insurer. Keep the number of a local locksmith with your household documents, and know where your spare key is kept, which should not be under a plant pot.

Getting help from Yale's UK-based support team

Yale runs a UK-based support team for its locks, alarms and doorbells. Before you contact them, have three things ready: the model name, the date and place of purchase, and for anything electronic, the app and phone you are using it with. That turns a long call into a short one.

For a lock that will not turn, or a door that will not secure, a qualified locksmith is often the faster answer, particularly if you are locked out or the door is your only exit. For an alarm or doorbell that has stopped working, the support team is the right first call, and the January 2028 support date for the Smart Video Doorbell⁴ tells you how long that route stays open.

If you need help because of a disability, there are routes that work alongside any maker's support line. Relay UK is a free service, available 24/7, that lets people who are deaf, hard of hearing or speech-impaired contact services by app, textphone or text message⁷. It is the same service used to reach the emergency services, and it can be used for ordinary customer service calls too¹⁰. For households where someone needs extra help in an emergency, our guide to Extra Help in an Emergency: Older, Disabled and Medically Dependent Households sets out the registers and contacts worth having on the fridge.

Keeping the kit ready through a power cut, storm or flood

Yale's security kit is built for ordinary life, and ordinary life includes bad weather. A few habits keep it working when it matters.

• Check the cylinder once a year. Look for the stars on the face, and check the cylinder does not protrude past the handle. If it does, get it changed⁶.
• Keep the door working. More than 200,000 injuries a year come from doors in dwellings⁵. A lock that needs forcing is a lock that will fail.
• Know what depends on power. The alarm and doorbell need mains power and a network. In a power cut they stop being security and become something to reset afterwards. Plan for the door to be your security when the power is off.
• Have a torch by the door. In a power cut, you want to be able to see the keyhole and check the face of the cylinder without a phone battery. Our guide to Emergency Lighting at Home: Torches, Lanterns and Candles covers what to keep.
• Check the doorbell's support date. Yale supports its Smart Video Doorbell until January 2028⁴. After that, plan for it to be replaced rather than relied on.

Flooding is the emergency that most directly affects a door. The government's flood risk management report for April 2024 to March 2025 records schemes protecting homes, including 1,780 homes at the Lydd Ranges sea defences¹¹. If you are in a flood risk area, know what your door is made of and how it will behave with water against it, and read our Flooding: A Household Guide before the season turns.

Where Yale fits a household emergency plan

A household plan has layers. The outer layer is the ordinary week: a door that locks properly, an alarm that works, a way to see who is calling. The middle layer is the disruption: a power cut, a storm, a burst pipe. The inner layer is the emergency itself.

Yale's cylinder sits in the outer layer and stays useful in all three, because it needs nothing to work. The alarm and doorbell sit in the outer layer and stop at the middle one. That is not a criticism of them; it is how you should plan around them.

For the rest of the layers, work through Getting Started: Preparing Your Household for an Emergency, then the kit guides for power cuts, storms, snow and ice and home emergencies. If your concern is the door being tried while you are in, our Home Security: A Household Guide covers the law on householders' rights and reasonable force, and what it is illegal to carry.
