The best ABUS window locks, compared.
Top pick: ABUS FG200 keyed-alike handles, set of 5 – Highest score at 86: five keyed-alike handles at about £27.19, 4.6 from 2,032 reviews. Spindle cutting and safety level 3 are already deducted. Best value: ABUS FG110 lockable window handle, white – About £13.71 for one handle, 4.6 from 759 reviews, with a 7 mm pin and 43 mm centres stated. One key and a fixed spindle keep it off the top. Updated October 2026.
An ABUS window lock is one of three products: a lockable handle, a hinge-side lock, or a bolt on the opening side. You are usually securing an accessible window, stopping a child turning a handle, or checking an insurance endorsement that asks for a key-operated lock. Quality here is the match to the window and the fixing. A handle only stops the lever if the spindle and the 43 mm screw centres fit. An add-on lock only holds if the screws reach timber or the steel inside uPVC. The order of checks is in the [ABUS window lock buying guide](/hub/door-and-window-security/abus-window-lock/sub/abus-window-lock-buying-guide). A safety restrictor that limits the clear opening to 100 mm is not in this set.

Personal buying guide
Question 1 of 2
Which part are you locking?
Across 2,032 amazon.co.uk reviews, the FG200 set (model 84581) is five white lockable handles at £27.19, keyed alike on AB208 keys, ranked 35 in Lockable Window Levers. Reviewers swap them for the old levers and use the adjustable 28–44 mm square pin, though some still cut the spindle shorter on the day. The listing states 43 mm screw centres, safety level 3, and that the handle locks without the key and opens with it. The action is often stiff until you have used it a few times, and the supplied screws are not always the ones the frame needs. One later extra handle was not the same key, and one reviewer treated the set as a child lock rather than burglary hardware. ABUS’s own retrofit guidance treats a lockable handle as the child-safety layer, not as a bolt on its own. It is the set to buy when several windows should share one key and the old holes are already 43 mm apart.
Pros
Cons
Best for: Replacing several white window handles on one AB208 key, when the old screw centres are 43 mm and you want the lever locked.
Less suitable: A single window, a hinge-side bolt, or a gearbox whose screw holes are not 43 mm apart.
Specifications
Common questions
Does the FG200 set use one key?
The listing includes five reversible keys marked AB208 and describes them as simultaneous locking, so the set is keyed alike.
What spindle and screw spacing does it state?
The listing states an adjustable square pin of 28–44 mm and screw spacing of 43 mm.
Do you need the key to lock it?
The listing says the lock is opened with the reversible key and closed again without a key.
At £13.71, the FG110 (part 592218) is one white lockable handle, rated 4.6 from 759 reviews, with a fixed 7 mm square pin and 43 mm centres. Reviewers who match those sizes describe a quick swap and a solid feel next to cheaper lockable handles, and they press the cylinder to lock and use the key to open. The listing says the handle cannot move once it is locked, which is the child-lock claim. Reviews say the box holds one key, so there is no spare if it is lost. The pin is fixed in the handle and was too short for some gearboxes, and one lock felt slightly loose. A child locked an adult on a balcony because the handle locks without the key. It suits one window whose old handle is already 7 mm and 43 mm, if the key stays reachable and out of a child’s hands.
Pros
Cons
Best for: One white handle on a window that already uses a 7 mm square pin and 43 mm screw centres.
Less suitable: Several windows that must share one spare key, or a gearbox that needs a longer spindle than this fixed pin.
Specifications
Common questions
Will the handle move when it is locked?
The listing says that when it is locked the handle cannot be moved, which is why it is described as a child lock.
What pin and screw spacing does it state?
The listing states a 7 mm square pin and 43 mm bolt spacing.
How many keys does the listing include?
The listing does not state a key count. Reviews on the listing say one key.
The white FAS97 (model 117824) is a keyless hinge-side lock at £40.10, listed at 4.6 from 485 reviews, for inward-opening pivot-hung windows. Reviewers use it against levering the sash off the hinges, and it latches automatically when the window closes, with two push-buttons and no key. The same 485-review count appears on the brown listing, so it is not a separate pile of opinions. Supplied screws are often too long, there is no drill template, and the instructions are called unclear. A screw or the drill can exit the far side of the frame, and the hold is weak unless the fixing reaches the steel in a plastic frame. Tilt self-hold can fade, so the sash has to be held by hand, and a bent spring tongue has arrived in the box. It has no detachable key, so it may not match a policy that asks for key-operated locks. It belongs on the hinge side of an inward-opening window that already shuts, if you can fix into something solid.
Pros
Cons
Best for: The hinge side of an inward-opening window or patio door, when a key is not required and the screws can reach steel or timber.
Less suitable: An outward-opening casement, or a policy that requires a key-operated lock with a detachable key.
Specifications
Common questions
Does the white FAS97 come with a key?
No. The listing says it is without keys and has two push-buttons.
Which windows does the listing name?
The bullets say inward-opening pivot-hung windows, on the hinge side. The title also names patio doors and balcony doors.
Is it tool-free to fit?
No. It is a screwed hinge-side lock. The title says the mounting is concealed.
The brown FAS97 (model 117800) is the same keyless hinge-side lock at £40.74, weighing 538 g on the listing, with stainless steel and alloy steel named and a printed maximum capacity of 1,000 kg. It shows the same 4.6 from 485 reviews and the same Window Locks & Latches rank as the white FAS97, so the stars are not a second test of the brown finish. The listing still says automatic latching, two push-buttons, and inward-opening pivot-hung windows, without a key. The review pattern matches the white unit: long screws, no drill template, a drill that can exit the frame, and a need for the steel core in plastic. Tilt self-hold fades, a spring has arrived bent, and one review describes a part failing after years. ABUS’s level 10 and the tonne figure are the maker’s claims for the lock, not a test of your frame. Buy the brown one when the frame is brown and the window opens inward. Leave it if the endorsement wants a detachable key.
Pros
Cons
Best for: A brown inward-opening window or French door that needs a hinge-side latch and does not need a key.
Less suitable: A white frame, an outward-opening casement, or wording that asks for a detachable key.
Specifications
Common questions
How is the brown FAS97 different from the white one in this set?
The listing is the brown finish, model 117800, weight 538 g, and it prints a 1,000 kg maximum weight capacity. It is still a keyless hinge-side lock for inward-opening windows.
What material does the listing give?
The material field reads stainless steel and alloy steel.
Does it need a key?
No. The bullets say automatic latching, without keys, with two push-buttons.
The FTS3003 W AL0125 (part 317354) is a white opening-side bolt at £28.81, rated 4.6 from 233 reviews, for inward-opening windows. The listing states a 4-pin cylinder, hardened steel in the safety-relevant parts, ABUS safety level 5, and keyed-alike AL0125: you close to lock and use the key only to open. Reviewers who pre-drill timber call the extra bolt straightforward, and some fit it beside a hinge-side lock. The supplied screws are often too long, the cover clips come loose, and a small position error stops the bolt meeting the strike. Fixing into the plastic of a uPVC frame is the weak point the reviews name, and the listing allows plastic French doors only with fixing anchors or injection mortar. ABUS lists the lock at 337 g; the amazon field of 4.54 g is not the weight. It is a keyed bolt for an inward-opening window whose frame will hold the screws, not a lock for a typical outward-opening UK casement.
Pros
Cons
Best for: An inward-opening window or French door where you want a keyed bolt on the opening side and the screws can reach timber or steel.
Less suitable: An outward-opening casement, or uPVC where the screw would only bite the plastic skin.
Specifications
Common questions
Can this bolt lock go on a plastic French door?
The listing says plastic French doors only hold in conjunction with fixing anchors or injection mortar. It also names aluminium and wood.
Do you need the key to lock it?
The listing says you simply close to lock, and the key is only required for opening.
What ABUS safety level does the listing state?
The listing states ABUS safety level 5. That is the maker’s scale, not PAS 24.
Scores use the five amazon.co.uk listings in this set and the review notes already on those cards. There is no lab test. All five kept listings print 4.6, so the UK review count does the separating. A handle is not scored as a hinge bolt, and a lockable handle is not scored as a 100 mm safety restrictor. The highest score is the top pick. The best price against a high score for a clear job is the best value. ABUS’s own 1-to-10 security level is not treated as PAS 24, EN 1627, Sold Secure, or Secured by Design. The maker’s tonne figure is not a test of your frame. The weights below sum to 100.
UK review count
35%The amazon.co.uk star line is 4.6 on every kept listing, so the count behind that star does the separating. A shared 485-review block on the white and brown FAS97 is not counted as two samples.
Job match
25%Whether the listing is one job: a lockable handle, a hinge-side lock, or an opening-side bolt. A handle is not scored as a hinge bolt, and an add-on lock is not scored as a PAS 24 window.
Stated sizes
20%Whether the box states the sizes that job needs. A handle without a spindle length, or a bolt whose amazon weight field is not a real mass, loses points.
Fixing and contradictions
20%Deductions for screws that exit the frame, a spindle that still has to be cut, a keyless lock where an endorsement asks for a detachable key, and a listing that contradicts itself.
Start with the job, then the opening direction, then whether a key has to come out of the lock. A star rating will not choose for you: every listing kept here prints 4.6. Price follows the job. It does not buy a PAS 24 window.
An ABUS window lock in this amazon.co.uk set is one of three products. A lockable handle replaces the lever. A hinge-side lock sits on the hinge side of an inward-opening window. A bolt sits on the opening side. A safety restrictor that limits the clear opening to 100 mm is not in this set. How those jobs differ is set out in [ABUS window lock or restrictor](/hub/door-and-window-security/abus-window-lock/sub/abus-window-lock-vs-restrictor).
A 100 mm safety restrictor and a lockable handle do different jobs. The handle stops the lever. It does not hold a 10 cm gap, and it does not make the window PAS 24.
The hold is weak unless the screw reaches timber or the steel inside the plastic. The FTS3003 listing allows plastic French doors only with fixing anchors or injection mortar.
FG200 is keyed alike on AB208. FTS3003 AL0125 is a different key. FAS97 has no key. Fitting FAS97 to an outward-opening casement, or leaving keys in view, are the other misses.
Decide the job before the price. A lockable handle replaces the lever. FG110 and FG200 lock without the key and open with the key, which is why listings describe them as a child lock on the handle. They do not bolt the sash. FTS3003 is a bolt on the opening side of an inward-opening window: close to lock, key only to open, keyed alike AL0125, ABUS safety level 5 on the maker’s scale. FAS97 is a keyless automatic latch on the hinge side, white or brown, for inward-opening pivot-hung windows.
A handle only stops the lever if the spindle and the 43 mm screw centres fit. FG110 states a fixed 7 mm square pin and 43 mm centres. Reviews say that pin was too short for some gearboxes, and that the box holds one key. FG200 states an adjustable square pin of 28–44 mm and 43 mm centres, and some reviewers still cut the spindle shorter on the day. The supplied screws are not always the ones the frame needs. An add-on lock only holds if the screws reach timber or the steel inside uPVC.
Three typical situations, each with a recommendation from this comparison.
You are replacing more than one white lever and you want the same key, with the key reachable at night and out of sight when you leave. The FG200 set is the top pick at about £27.19: five handles, keyed alike on AB208, if the old holes are already 43 mm apart.
You have one window whose old handle is already a 7 mm square pin on 43 mm centres. The FG110 is the best value at about £13.71. Reviews say the box holds one key, and the pin is fixed, so it can be too short for some gearboxes.
You want the words key-operated and a detachable key on an inward-opening window or French door, and the screws can reach timber or steel. The FTS3003 bolt is about £28.81, safety level 5 on ABUS’s own scale, keyed alike AL0125. A keyless FAS97 may not match that endorsement.
The ABUS FG200 set of five white handles is the top pick. It scores 86, the highest in this set, at about £27.19, with 4.6 from 2,032 reviews and one AB208 key. Spindle cutting and safety level 3 are already in that score. The ABUS FG110 is the best value at about £13.71 for one handle, with 4.6 from 759 reviews, a stated 7 mm pin and 43 mm centres. One key and a fixed spindle that can be too short keep it off the top. A hinge lock and an opening-side bolt are different jobs. None of these listings is a PAS 24 window or a 100 mm safety restrictor.
