ABUS window lock buying guide

Updated: October 2026

The shelf has answered one search with three pieces of hardware: a handle that stops the lever, a hinge-side latch with no key, and a bolt on the opening edge. An ABUS window lock buying guide starts there, because these five listings are not sizes of the same product. The [ABUS window lock comparison](/hub/door-and-window-security/abus-window-lock) holds the cards and the review counts. This page is which side you are holding, whether a key has to come out, and when none of these products is the right buy. Peter F. checked the listings on 19 October 2026. There was no lab test. A qualifying purchase can earn a commission at no extra cost to you.

Three ABUS jobs, not one product

A lockable handle replaces the lever. In this set that is the FG110, one white handle, and the FG200, five white handles. Both lock without the key and open with the key. ABUS’s retrofit guide treats that layer as child safety, and says it is not enough against prying on its own. The FAS97 latches on the hinge side of an inward-opening window, with two push-buttons and no key. The FTS3003 is the opening-side bolt, keyed alike on AL0125: close to lock, key only to open, safety level 5. If the sash opens out, only a handle can match, and only if the spindle and the 43 mm centres fit. The ranking is the best ABUS window lock page.

Key, direction, and frame

FTS3003 and FAS97 are specified for inward-opening windows and French doors. A side-hung casement that swings out is a handle problem. A sash is not in this set, and a new handle will not become a sash stop. The ABI says many insurers want locks on ground-floor opening windows. AXA Connect LC01, where that endorsement applies, asks for key-operated locks with detachable keys, keys out of view when you are out, and keys allowed in escape-route locks at night. FG110, FG200, and FTS3003 open with a key. FAS97 does not. Timber can take the right screw. A screw that only bites the plastic skin pulls out. The FTS3003 listing allows plastic French doors only with fixing anchors or injection mortar.

What the security level does not mean

FG200 prints ABUS safety level 3. FTS3003 prints level 5. FAS97 is level 10 on ABUS’s own page, with more than one tonne stated, and the brown listing prints 1,000 kg. That is the maker’s 1-to-10 scale. It is not PAS 24, EN 1627, or Sold Secure. The white FAS97 listing does not print a level. Approved Document Q, requirement Q1, applies to new dwellings, not an ordinary retrofit. Secured by Design now points to PAS 24:2022 and the later amendment for the window as manufactured. Screwing a lock onto an old sash does not make that sash PAS 24. The tonne figure is a claim about the lock, not a test of your screws or your glass.

Which listing in this set

For one window with a 7 mm square and 43 mm centres, the FG110 is the best value: 4.6 from 759 reviews, one key in the box according to reviews, and a fixed pin that was too short for some gearboxes. For several windows on one key, the FG200 is the top pick: five handles, AB208, an adjustable pin of 28–44 mm, and 4.6 from 2,032 reviews. That AB208 key does not operate the FTS3003 AL0125. On an accessible inward-opening window, the FTS3003 is the keyed bolt if the screws can hold. The white FAS97 is the hinge-side partner when you do not need a key. The brown one is the same lock for a brown frame, and both show 4.6 from 485 reviews, so that count is one file. Leave the set for an outward-opening bolt, a sash, or a window that is the only way out.

Common questions

Which of these works on an outward-opening UK casement?
The handles can, if the spindle and the 43 mm screw centres match the old lever. FAS97 and FTS3003 are described for inward-opening windows and French doors. An outward-opening casement is the wrong job for those two, even when the frame is uPVC. A sash, a slider, and a roof window are outside this set entirely.
Do I need a key to lock it, or only to open it?
The FG110, the FG200, and the FTS3003 lock when you close or press them, and the key is for opening. The FAS97 has no key at all. A policy that asks for a detachable key is aimed at the keyed products, where that wording applies. The FG200 key is AB208. The FTS3003 key is AL0125. They are not the same.
Will FAS97 satisfy a policy that says key-operated locks?
Where the endorsement says key operated and detachable keys, a keyless FAS97 does not match that sentence. Other policies only ask for locks on accessible windows. Read the schedule you hold before you treat the hinge lock as accepted. The ABI line about ground-floor windows is not the same as AXA Connect LC01.
What does ABUS security level 3, 5, or 10 mean in the UK?
It is ABUS’s own scale. Level 3 is printed on the FG200 listing, level 5 on the FTS3003, and level 10 on the FAS97 maker page. None of those numbers is PAS 24 or a police certificate for your existing window. The tonne figure on the FAS97 is a claim about the lock, not a test of your screws or your glass.
When is the right answer a new PAS 24 window instead?
When the requirement is the window as a whole: a new dwelling under Approved Document Q, a Secured by Design route, or a named insurance standard. An add-on lock from this set does not confer that certificate on an old frame. Secured by Design now points to PAS 24:2022 and the later amendment.
