The best door locks, compared.
Top pick: Yale 77 nightlatch – Highest score at 92: 4.6 from 3,166 reviews at about £11.64, a 60 mm standard-security nightlatch. Two keys, missing screws and lighter metal are already deducted. The listing does not state BS 3621. Updated October 2026.
A door lock has to match the door you already have. Timber usually takes a mortice in the edge and a nightlatch on the face. uPVC and composite doors lock with a multipoint strip and a euro cylinder. AA Insurance, Allianz and AXA's LC01 cluster around BS 3621 on timber, or a key-operated multipoint, and they care that the lock is used. The Yale 77 is both the highest score and the lowest price, and the award field holds one badge. Judge the lock by the Kitemark, or by Sold Secure. Which family fits the door is set out in the [door lock buying guide](/hub/door-and-window-security/door-lock/sub/door-lock-buying-guide). It latches as the door shuts, and the snib can hold the latch back or deadlock it from inside.

Question 1 of 2
Which door is the lock for?
The Yale 77 is a 60 mm nightlatch at about £11.64 on amazon.co.uk, rated 4.6 from 3,166 reviews, and the listing calls it standard security. Reviewers use it as a straight swap for an older Yale or Union of the same shape, often in a few minutes, on a timber door, a back gate, or beside a mortice they already have. The box includes a rim cylinder and two keys, and the snib can hold the latch back or deadlock it from inside. Two keys is the complaint that keeps returning, because people then pay to have more cut. Screws are often missing, so the lock cannot go on the same day, and the metal is described as lighter or more brittle than the lock it replaced. A snib that is too stiff to push has been enough for a return, and one case sat slightly taller, so the timber needed a small groove. The listing mentions anti-bump and does not state BS 3621, TS007 or Sold Secure.
Pros
Cons
Best for: You are replacing the same 60 mm nightlatch on a timber door or back gate, especially beside a mortice you already lock.
Less suitable: A final exit whose schedule asks for BS 3621, or a uPVC door that needs a multipoint cylinder.
Specifications
Common questions
Is the Yale 77 a BS 3621 lock?
The amazon.co.uk listing calls it standard security and mentions anti-bump protection. It does not state BS 3621, TS007 or Sold Secure.
How many keys come with the Yale 77?
The listing includes a rim cylinder and two keys. Reviewers often say two is not enough and pay to have more cut.
What backset is this nightlatch?
60 mm. It suits an existing hole at that distance from the door edge. One reviewer also turned the latch for a right-hand door.
The Nuki Smart Lock Ultra is about £309 on amazon.co.uk, rated 4.5 from 663 reviews, and the box includes a universal euro cylinder, a mounting plate, a charging cable and a black cover as well as the white one fitted. The motor turns that cylinder by app, button, remote or voice, with Bluetooth, Wi-Fi and Matter named on the listing, and a key still works. UK reviewers have fitted it to a new-build door, a composite door, a three-point lock and a slam-lock front door, and several say the outside still looks like an ordinary cylinder. The listing says no drilling and under 15 minutes. UK reviews run from about 20 minutes to a fiddly or multi-hour alignment, and some doors still need the handle lifted before the motor will lock. A full charge is stated as two hours, with months of use claimed from one charge, yet more than one UK reviewer had the charging cable fail until support sent another. One UK reviewer says the door unlocked as they drove past, and another puts access without the app at £70 a year, which is that reviewer's figure rather than a price on the listing. The amazon.co.uk capture does not state TS007, BS 3621 or Sold Secure.
Pros
Cons
Best for: You want keyless locking on a euro-profile door, including composite and three-point doors in the UK reviews, and you will live with the app and the battery.
Less suitable: You need a TS007 cylinder named on the listing, or you will not tolerate alignment, a handle you still lift, and a proprietary charging lead.
Specifications
Common questions
Does the Nuki Ultra include a cylinder?
Yes. The box lists the Smart Lock Ultra, a universal euro cylinder, a mounting plate, a charging cable, and a black cover as well as the white one fitted.
Does the listing say it works with Alexa?
The controller line names Amazon Alexa, Google Assistant, SmartThings, Android and iOS. Connectivity is Bluetooth, Wi-Fi and Matter. There is no separate test result in the capture.
Do you have to drill the door?
The listing says no drilling and no extra tools, and quotes under 15 minutes. UK reviewers also describe fiddly cylinder alignment, and some still lift the handle before the door will lock.
The ANNFUZ UK6201C is a polished-chrome mechanical keypad at about £50, rated 4.3 from 7 amazon.co.uk reviews, and that review count is the whole file. It takes a 4–7 character code, locks itself as the door closes, and has a passage mode when the door should stay open to traffic. There is no battery and no wiring. The listing fits doors of 35–60 mm with a fixed 60 mm backset, left- or right-hand levers, and it says the lock is not for glass. Reviewers describe a solid zinc-alloy handle and a clean finish, and they used it on an office door, an internal door and a utility cupboard. One UK reviewer says the set buttons open the lock in any order, and that an extra button does not, which is weaker than a code you must enter in sequence. The listing says press C, then the code. Setting it takes care, one reviewer called support poor, and about £50 felt high for a cupboard. No failed mechanism is in these seven reviews, and no BS 3621, TS007 or Sold Secure line is on the listing.
Pros
Cons
Best for: You want a battery-free code on a gate, store, office door or cupboard, and you accept a code that a reviewer found was not order-sensitive.
Less suitable: A final exit that needs a sequential code or a stated BS 3621 lock, or a glass door.
Specifications
Common questions
Does this keypad need batteries?
No. The listing describes a fully mechanical push-button lock with no batteries and no wiring.
Must the code be entered in order?
A UK reviewer says the set buttons open the lock in any order, and that an extra button does not. The listing says press C, then a 4–7 character code.
Will it fit a glass door?
The listing says it is not for glass doors. It states 35–60 mm door thickness, a fixed 60 mm backset, and left- or right-hand levers.
The QWORK WD7069 is a gold surface night latch at about £11.99, rated 4.1 from 437 amazon.co.uk reviews, for doors the listing puts at 35–64 mm with a 32 mm hole. Reviewers buy it when an old rim lock's holes already match and a shop no longer stocks that gold pattern, including a garage, a basement door or a period timber door. The bullet states more than 250,000 cycles, which is a listing claim and not a test in this comparison, and the backset is not stated. The same review file describes light, cheap-looking metal, a stiff latch that needs a jiggle, and keys that one reviewer could not get copied. Failures are specific: a tumbler that came out with the key after about two months, a mechanism that broke after a few months of daily use, and a key that snapped in the cylinder. A listing field says App, while the bullets, the keys and the reviews describe a mechanical key lock. No BS 3621, TS007 or Sold Secure line appears, and one reviewer on a metal door returned it the same day because the old holes did not line up.
Pros
Cons
Best for: You want the gold look of an old rim latch on a garage, basement or secondary timber door, and the existing holes already line up.
Less suitable: An important final exit, a metal door with different holes, or anyone reading the App field as a smart lock.
Specifications
Common questions
Is the QWORK night latch an app lock?
No. The bullets describe a key, a brass latch and an angle strike. A listing field says App, and that field conflicts with the rest of the capture.
What door thickness does it state?
35–64 mm, and a 32 mm hole for the latch mechanism. Backset is not stated. One reviewer on a metal door could not use the old holes.
Does the listing name a security standard?
No BS 3621, TS007 or Sold Secure line. Reviewers often call the metal light compared with the old lock it replaced.
Scores use the four amazon.co.uk listings on this page and the UK review notes already captured for them. There was no lab test. Stars and review counts are the UK figures on those listings. The weights below sum to 100 and follow the buying order in the digest: the door, the mark a schedule names, the measurements, what happens as the door shuts, then keys, battery and code. The highest score is the top pick. No best-value badge is awarded. The Yale 77 is both the highest score and the lowest shelf price, so a second badge on that listing would duplicate the award, and the dearer listings are not the better value. None of these four is scored as BS 3621, TS007, Sold Secure or a PAS 24 doorset.
Door match
30%Whether the lock suits the door you have. Timber can take a mortice and a rim nightlatch. uPVC and composite doors need the multipoint and a flush cylinder. A nightlatch on a plastic face does not throw the hooks.
Schedule mark
25%Whether the listing states the mark a UK schedule names: BS 3621 on timber, BS 8621 where you must leave without a key, or TS007 3-star on a cylinder. Standard security and anti-bump are not those marks.
Measurements
20%Whether backset, door thickness and cylinder length are stated and match. Nightlatch backset is the door edge to the keyhole. Trade guides treat 60 mm as the usual nightlatch size.
How it locks
15%What happens as the door shuts. A spring nightlatch only latches. Auto-deadlock, a snib, passage mode and a motor on a cylinder are different behaviours, and passage mode is unlocked.
Keys, battery and code
10%How many keys are in the box, whether a battery or a charging lead is required, and whether a code has to be entered in order. A failed lead or a non-sequential code is deducted.
Match the lock to the door, then to the mark on your schedule, then to the measurements. A high star rating on a nightlatch does not make it a BS 3621 mortice, and a smart lock on a euro cylinder does not replace the multipoint strip. The four listings here cover a standard-security nightlatch, an antique rim latch, a mechanical keypad and a rechargeable smart lock. Prices run from about £11.64 to about £309.
A UK door lock follows the door you already have. On timber, the usual pair is a mortice in the edge and a nightlatch on the face. The nightlatch is a surface lock with a rim cylinder and a snib. It latches as the door shuts, and the snib can hold the latch back or deadlock it from inside. A mortice sits in the door edge. None of the four listings here is a mortice. On uPVC and composite doors the lock is a multipoint strip.
The listing says standard security and mentions anti-bump. It does not state BS 3621, TS007 or Sold Secure. Yale's BS1, from £76.99 on Yale's UK shop, is the kitemarked nightlatch, and it is not in this shortlist.
Nightlatch backset is the door edge to the centre of the keyhole. Trade guides name 40 mm and 60 mm. The Yale listing is 60 mm. The ANNFUZ backset is fixed at 60 mm. The QWORK backset is not stated.
Passage mode on the ANNFUZ leaves the door open to traffic. On a multipoint door the police.uk line is lift, lock, remove. A euro cylinder that stands proud of the handle is the projection West Yorkshire Police warn about.
The first split is the door, not the star rating. Timber can take a mortice in the edge and a rim nightlatch on the face. uPVC and composite doors lock with a multipoint strip, and the part you change is the cylinder, which has to sit flush. A nightlatch on a plastic face does not throw the hooks. A 60 mm nightlatch swap beside an existing mortice is the Yale 77 job. Fewer keys on a euro-profile door, with the multipoint kept, is the Nuki job.
Measure the nightlatch backset from the door edge to the centre of the keyhole before you order. Trade guides name 40 mm and 60 mm, and they treat 60 mm as the usual size. The Yale listing is 60 mm. The ANNFUZ states doors of 35–60 mm, a fixed 60 mm backset, left- or right-hand levers, and it excludes glass. The QWORK states 35–64 mm and a 32 mm hole, and the backset is not on the listing. Euro cylinders are outside and inside lengths from the fixing screw.
Three typical situations, each with a recommendation from this comparison.
You already lock a mortice and you are swapping the same 60 mm nightlatch on a timber door or back gate. The Yale 77 is the top pick at about £11.64, with 4.6 from 3,166 reviews. The listing says standard security. It does not state BS 3621. The box has two keys, and screws are often missing.
You have a uPVC or composite door and you want keyless use while the multipoint stays. The Nuki Smart Lock Ultra is about £309, with 4.5 from 663 reviews, and the box includes a universal euro cylinder. The amazon.co.uk capture does not state TS007 or BS 3621. Alignment and the charging lead are the limits in UK reviews.
You are locking a gate, store, office door or cupboard and you do not want a battery. The ANNFUZ mechanical keypad is about £50, with 4.3 from 7 reviews, for doors 35–60 mm and a fixed 60 mm backset. It is not for glass. One UK reviewer found the code works in any button order.
The Yale 77 nightlatch is the top pick. It has the highest score of these four amazon.co.uk listings, 92, at about £11.64, with 4.6 from 3,166 reviews, for a 60 mm standard-security nightlatch. Two keys, missing screws and lighter metal are already in that score. No best-value badge is awarded. The same listing is also the lowest price, and the award field holds one badge. The QWORK at about £11.99 scores 82, with breakage reports, so it is not a separate value pick. The ANNFUZ at about £50 and the Nuki at about £309 are dearer. None of the four is BS 3621, TS007 or Sold Secure.
Yale 77 nightlatch
Highest score at 92: 4.6 from 3,166 reviews at about £11.64, a 60 mm standard-security nightlatch. Two keys, missing screws and lighter metal are already deducted. The listing does not state BS 3621.
No best-value badge. The Yale 77 is both the highest score and the lowest price, at about £11.64, so the award field holds one badge, the top pick. The QWORK at about £11.99 scores lower, with breakage reports. The ANNFUZ and the Nuki are dearer.
