The best keyed-alike padlocks, compared.
Top pick: ABUS 64TI/40 4-pack – Highest score: ABUS 64TI/40 four-pack, 4.7 from 386 reviews at about £31.01, with a stated 6.5 mm shackle. Level 5 is the maker's average-risk scale, not CEN 5. Best value: SEPOX long-shackle 4-pack – About £18.96 with a score of 88 and 4.4 from 1,623 reviews. Rank 1 is popularity. Shackle rust and a hammer review keep it off the top pick. Updated October 2026.
A keyed-alike padlock set is several padlocks that open with the same key. You use it for a shed, a side gate, a garage or a locker, so you are not carrying a different key for each hasp. It is whether the carton really is one suite, whether the shackle fits the hasp, whether the body still turns after British rain, and whether a or Sold Secure mark is printed. None of the eight amazon.co.uk packs here prints a grade or a Sold Secure mark. Security level 5 is the maker's 1-to-10 scale for average risk, not grade 5. Sharing a key does not lower the tests of that model. One lost or copied key opens every lock in the suite. The [padlocks keyed alike buying guide](/hub/door-and-window-security/padlocks-keyed-alike/sub/padlocks-keyed-alike-buying-guide) sets out suite scope, shackle fit and grades before you choose a pack size. Five spare keys for one lock are not a keyed-alike set.

Personal buying guide
Question 1 of 2
What are you locking?
The ABUS 64TI/40 four-pack is four 40 mm Titalium locks and five keys at about £31.01, at 4.7 from 386 amazon.co.uk reviews. The listing prints ABUS security level 5, which is the maker's 1-to-10 scale, and it says the lock is for medium-sized valuables or an average risk of theft. It does not print a CEN grade or a Sold Secure mark. The shackle is hardened steel, 6.5 mm thick, with 23 mm of clear height and 22 mm of clear width on a 40 mm aluminium body. United Kingdom reviews treat the shared key as the reason for buying, and they mention rain and about a year outdoors. One buyer had been told beforehand that the locks were not keyed alike, so the carton still needs a check on day one. The details weight is 200 g and a bullet says 87 g each, which the file does not reconcile.
Pros
Cons
Best for: Average-risk sheds and gates, which is the limit printed on the listing, if a 6.5 mm open shackle fits the hasp.
Less suitable: A policy that names Sold Secure or a BS EN 12320 grade, or a staple this 23 mm clearance will not enter.
Specifications
Common questions
Is security level 5 a CEN grade?
The listing prints ABUS security level 5 and says the lock is for medium-sized valuables or an average risk of theft. It does not print a CEN grade or a Sold Secure mark.
What shackle size is printed?
Diameter 6.5 mm, clear height 23 mm, clear width 22 mm, on a 40 mm body.
Are the four locks one key?
The bullet says yes, with five keys. UK reviews describe that as the reason for buying. One buyer had been told beforehand that they were not keyed alike.
The KAWAHA 41/50 is two 50 mm shrouded padlocks and six keys at about £27.99, at 4.5 from 21 amazon.co.uk reviews. The key comes out only when the lock is locked, so you cannot pocket it while the shackle is still open. The bullets say SUS304 stainless steel, and the details also list brass, so the body description is split. One United Kingdom review left the pair on parking bollards for about six weeks of rain and saw no rust. Twenty-one reviews is a short sample, and six weeks is not a British winter. A seller line claims a pull of more than 4 tons, with no test report in the file. No CEN grade is printed, and the shared key covers this pair only.
Pros
Cons
Best for: A gate or a bollard if a shrouded pair is what you need and you can accept a 21-review file.
Less suitable: A shed that needs four locks, or a winter you want described by more than one six-week note.
Specifications
Common questions
Can you take the key out while the lock is open?
No. The listing says the key can only be removed when the padlock is locked.
Does the listing show a CEN grade?
No. Anti-drill and cut resistant are feature labels. A pull figure of more than 4 tons is a seller sentence with no test report in the file.
How has it coped with rain?
One UK review left the pair on parking bollards for about six weeks of rain and saw no rust. The listing has 21 reviews in total, so that is a short sample.
The SEPOX long-shackle four-pack is four locks at about £18.96, ranked 1 in Keyed Padlocks on amazon.co.uk, at 4.4 from 1,623 reviews. The title says a 58 mm shackle, which is why buyers put it on a gate or a locker hasp that a short bow will not reach. Rank 1 is a sales position, not a CEN grade, and no Sold Secure mark is printed. The included-components line says four padlocks with the same key and does not number the keys. A United Kingdom review mentions two. Buyers use them on gates, sheds and a school locker. One review says the shackle rusts in UK weather while the lock still works. Another said a hammer blow took a lock apart.
Pros
Cons
Best for: A gate or locker hasp that needs the extra shackle length, if you can live with rust on the bow and you do not need a printed grade.
Less suitable: A street-facing hasp where a long open shackle is easy to cut, or a contents list that asks for Sold Secure.
Specifications
Common questions
How many keys come with the four locks?
The included-components line says four padlocks with the same key and does not give a number. A UK review mentions two keys.
Does rank 1 mean a security grade?
No. The amazon.co.uk listing ranks it 1 in Keyed Padlocks. No CEN grade or Sold Secure mark is printed.
What do UK reviews say about rain?
Buyers use them on gates, sheds and a school locker. One review says the shackle rusts in UK weather while the lock still works. Another said a hammer blow took a lock apart.
The KAWAHA 81/40 is four 40 mm padlocks and six keys at about £28.99, listed at 4.4 from 467 amazon.co.uk reviews. The bullet says the locks are keyed alike inside this set only, and that a different KAWAHA carton will not open them. The details field says brass, while a bullet also says a high-strength zinc alloy body, and the file does not choose between them. The shackle is hardened steel, and the pack includes a shrink tube. One United Kingdom review said that tube would not shrink onto the tight radius and was damaged in use. There is a one-year warranty line and no printed CEN or Sold Secure mark. The listing also carries an App control field, and the product text describes a key padlock with no app.
Pros
Cons
Best for: A shed, gate or locker hasp that takes a 40 mm open shackle, if you only need the locks in this carton.
Less suitable: Anyone who wants to add a fifth lock on the same key next year, or who needs the body metal stated once.
Specifications
Common questions
Will another KAWAHA carton use the same key?
No. The bullet says keyed alike within the same set only, and that different sets are not mutually unlocked.
What is the body made of?
The details field says brass. A bullet also says a high-strength zinc alloy body. Both lines are in the listing, and the file does not choose between them.
Does the shrink tube work?
It is in the pack for the shackle. One UK review said it would not shrink onto the tight radius and was damaged in use.
The SEPOX three-pack is three laminated 40 mm locks and six keys at about £13.97, at 4.3 from 414 amazon.co.uk reviews, with a five-year warranty line. Many reviews praise one key for a shed and a toolbox. One United Kingdom review said a lock was useless after about two weeks, and another found the locks unsuitable outside after about six months. The body is listed as laminated alloy steel with a weather-proof finish, and no CEN or Sold Secure mark is printed. Shackle diameter is not stated, so the hasp still has to be measured against the bow you receive. The listing fields say App and Wi-Fi. The bullets, the pack contents and the reviews describe a key padlock, and there is no app in the product text.
Pros
Cons
Best for: A low-cost shed and toolbox set if you accept mixed outdoor reviews and you measure the shackle yourself.
Less suitable: A gate you will not see for months, or anyone who read the App field and expected a phone lock.
Specifications
Common questions
Is this a Wi-Fi padlock?
The listing fields say App and Wi-Fi. The bullets, the pack contents and the reviews describe a key padlock. There is no app in the product text.
How many keys are in the pack?
The included-components line says three padlocks and six keys.
Do the reviews agree on outdoor use?
Many praise one key for a shed and a toolbox. One UK review said a lock was useless after about two weeks, and another found them unsuitable outside after about six months.
This SEPOX listing is titled as six long-shackle locks at about £23.97, and the star line is 4.3 from 414 reviews, the same figures and the same DIY rank as the three-pack B0CPY9CN2Q. The title and the item count say six. The included-components line says three padlocks and six keys. Most of the review texts talk about three locks, so those 414 reviews are not a verdict on a six-lock suite. The title says a 58 mm extra-long shackle, and the dimensions line is 40 × 22 × 91 mm. Shackle diameter is not stated. No security grade is printed. The file does not resolve how many bodies are in the carton.
Pros
Cons
Best for: Only a buyer who counts the bodies in the carton before fitting any of them.
Less suitable: Anyone choosing by the word six in the title, or by the star line, without opening the box.
Specifications
Common questions
Does the pack contain six locks?
The title and the item count say six. The included-components line says three padlocks and six keys. The file does not resolve that.
Why is the star rating the same as the 3-pack?
This listing prints 4.3 from 414 reviews and the same DIY rank as B0CPY9CN2Q. Most of the review texts talk about three locks.
How long is the shackle?
The title says 58 mm extra long. The dimensions line is 40 x 22 x 91 mm. Shackle diameter is not stated.
The Maudex IP450 is four covered padlocks and 12 keys at about £26.99, and the amazon.co.uk listing sits at 4.3 from 168 reviews. The body is described as iron under black plastic, with rubber rings and a weather-resistant line, and no CEN grade or Sold Secure mark is printed. The listing says the 12 keys work across the four locks. Several United Kingdom reviews found only three the same, or two pairs, and one buyer returned the set. A keyed-alike shed and gate only works if every lock turns on the first afternoon, so that carton check is the whole point of the pack. One reviewer could not pass the rubber weather section through the hole in their gate bolts. Weather resistant is a feature line, not a test result in this file.
Pros
Cons
Best for: A shed or gate set if you try every key in every lock on the day it arrives and the cover actually passes the bolt.
Less suitable: A gate bolt the rubber section will not enter, or any hasp where you cannot check the keys before you rely on them.
Specifications
Common questions
Are all four Maudex locks the same key?
The listing says the 12 keys work across the four locks. Several UK reviews found only three the same, or two pairs, and one buyer returned the set.
Will the cover fit a gate bolt?
One reviewer could not pass the rubber weather section through the hole in their gate bolts. Measure the hole before you rely on it.
Is a security grade printed?
No. The file has no CEN grade and no Sold Secure mark. Weather resistant is the special-features line.
The OGMBI D34144 is six round discus padlocks and 12 keys at about £22.99, and the amazon.co.uk listing is 2.8 from 13 reviews. The title says one key opens all six. Several United Kingdom reviews say it does not, including one that found only two the same, while one review said a single key did open them. A closed shape does not rescue a carton whose keys may not match. The feature line says waterproof. Reviews say rain gets in and that the locks were hard to open after about three months outside. A review also says the shackle toe has no notch and the body feels light. No security grade is printed.
Pros
Cons
Best for: A buyer who has already tried every lock and is only keeping the ones that match.
Less suitable: A shed or a gate you intend to lock and leave, which is the use the reviews in this file do not support.
Specifications
Common questions
Do all six open with one key?
The title says they do. Several UK reviews say they do not, including one that found only two the same. One review said one key did open them all.
Are they waterproof?
The feature line says waterproof. Reviews say rain gets in and that they were hard to open after about three months outside.
Is a security mark printed?
No. A review also says the shackle toe has no notch and the body feels light.
Eight amazon.co.uk keyed-alike padlock listings were scored from the listing text and the review notes already on file. There is no laboratory test. Star ratings count only with the UK review file behind them. A keyed-alike claim that those reviews deny, or a title that says six locks while the components line says three, is a heavy deduction. A stated shackle diameter and clearance rank above body width alone. ABUS security level 5 is the maker's 1-to-10 scale, not a BS EN 12320 grade. No listing in this set prints a CEN grade or a Sold Secure mark. The highest score is the top pick. The best price against a still-useful score for a real hasp is the best value.
UK review evidence
25%Amazon star rating, then a deduction when few reviews sit behind it, or when the same star line is printed on two packs.
One suite in the carton
25%A keyed-alike claim that United Kingdom reviews deny is a heavy deduction. A title that says six locks while the components line says three is the same kind of deduction.

Price in this set

Decide how many locks you need, whether this carton is really one key, then whether the shackle enters the hasp, then whether anyone has asked for a printed grade. A long bow is a fit fact, not a security grade. None of the eight amazon.co.uk listings here prints a CEN grade or a Sold Secure mark. ABUS security level 5 is the maker's 1-to-10 scale for average risk. The top pick is the ABUS 64TI/40 four-pack at about £31.01. The best value is the SEPOX long-shackle four-pack at about £18.96.
A keyed-alike padlock set is several padlocks sold to open with the same key. In the UK that is usually a shed, a side gate, a garage and a locker, so you are not carrying a different key for each hasp. Five spare keys for one lock are not a keyed-alike set. Sharing a key does not change the security tests of that model. It does mean one lost or copied key opens every lock in the suite. Locks Direct states that point.
Five keys in a box can all open one lock. Keyed alike means the locks in the suite share a key. Sharing that key does not lower the tests of the model. It does mean a lost or copied key opens every lock you fitted.
KAWAHA prints that different sets are not mutually unlocked. These packs are not rekeyable. If you need a fifth lock next year, or a match to a house cylinder, this is a locksmith job, not a second click of the same listing.
A 58 mm bow reaches a gate hasp and leaves more metal for cutters. ProtectUK wants a close shackle, or a shroud, on a gate. A waterproof line, including on the 2.8-star discus pack, is a feature sentence, not a test result.
The first check is whether the carton is one suite, and whether you can buy another lock on that key later. Keyed alike within this set only, which the KAWAHA 81/40 bullet prints, is an honest limit. It is not a reorderable key number. Count the hasps before you choose a pair, a three-pack or a four-pack. Five spare keys for a single lock are a different product. Then prove the keys on delivery.
Measure the hasp, not the body. The figures that matter are shackle diameter, clear height and clear width. The ABUS 64TI/40 states 6.5 mm, 23 mm clear height and 22 mm clear width on a 40 mm aluminium body. The SEPOX long-shackle titles say 58 mm, which reaches a gate a short bow will miss, and also leaves more metal for cutters. ProtectUK wants a close-shackle padlock, or a shroud, on gates, and two hasps with closed shackles on a wooden shed door.
Three typical situations, each with a recommendation from this comparison.
You want one key for a gate, a shed and a toolbox, and you will try every lock on the day the carton arrives. The ABUS 64TI/40 four-pack is about £31.01, with 4.7 from 386 reviews and a stated 6.5 mm shackle. Security level 5 is the maker's average-risk scale, not a CEN grade.
The hasp needs a longer shackle than a 40 mm open bow. The SEPOX long-shackle four-pack is about £18.96, with 4.4 from 1,623 reviews, and the title says 58 mm. Rank 1 is a sales position. Reviews report shackle rust, and one says a hammer blow took a lock apart.
You need a pair, not a four-pack, and a shrouded body. The KAWAHA 41/50 is about £27.99, with 4.5 from 21 reviews, and the key comes out only when the lock is locked. Twenty-one reviews is a short sample. A policy that names Sold Secure or a CEN grade is outside this whole set.
The ABUS 64TI/40 four-pack is the top pick: the highest score in this set, about £31.01, 4.7 from 386 amazon.co.uk reviews, and a stated 6.5 mm shackle with 23 mm of clear height. ABUS security level 5 is the maker's average-risk scale, not CEN grade 5, and no Sold Secure mark is printed. The SEPOX long-shackle four-pack is the best value at about £18.96 with a score of 88 and 4.4 from 1,623 reviews. Shackle rust and a hammer review keep it off the top pick. The three-pack is cheaper at about £13.97 and does not take that badge, because the four-pack costs about £5 more with a higher score and a much larger review count. None of these eight packs is a printed CEN or Sold Secure lock.
ABUS 64TI/40 4-pack
Highest score: ABUS 64TI/40 four-pack, 4.7 from 386 reviews at about £31.01, with a stated 6.5 mm shackle. Level 5 is the maker's average-risk scale, not CEN 5.
SEPOX long-shackle 4-pack
About £18.96 with a score of 88 and 4.4 from 1,623 reviews. Rank 1 is popularity. Shackle rust and a hammer review keep it off the top pick.
