Replacement keys for the Logitech Signature Slim MK955
The Signature Slim MK955 sits on office desks, often by the dozen. When a key breaks, replacing the whole workstation set makes no sense: we sell keys individually from €8, with an invoice, and you can order several parts in a single shipment.
Which key do you receive?
For the Signature Slim MK955 we ship a compatible Logitech MX Keys key: same scissor mechanism, same mounting footprint, same key profile. It is not necessarily the official Signature Slim MK955 key — the legend, shade or finish may differ slightly from the original. It clips onto the hinge already on the keyboard and behaves exactly like the key it replaces. The reason is a simple constraint: Logitech sells no individual keys, for any of its keyboards. The only part available on the market is the one from the MX Keys family, whose mounting footprint is shared across the brand's entire range of flat keyboards. Rather than let a keyboard go to landfill over a few millimetres of plastic hinge, we ship the part that fits mechanically, and say plainly what it is. The hinge is included with every keyboard key, and the 30-day money-back guarantee covers any compatibility issue.
An office combo built on the Signature Slim
The MK955 is the Signature Slim keyboard-and-mouse combo aimed at professional environments. Its keyboard carries the Signature Slim mechanics: flat keys, scissor hinges, a mounting footprint shared with the MX Keys family. A compatible MX Keys key therefore fits it directly.
Maintaining a keyboard fleet
Across a fleet, the same keys fail in the same places: space bar, Enter, left Shift, Caps Lock. Keeping a small buffer stock of those four parts costs less than a single replacement keyboard and removes workstation downtime. The flat €3 shipping applies to the whole order, not per part.
Fitted in under a minute
Place the key over the scissor hinge already on the keyboard and press straight down in the centre until it clicks. No tools, no disassembly, no re-pairing. If the hinge itself is split — the most common failure, rather than the cap — replace it first: hinges are sold individually or in packs under Parts & Tools.
Pricing, invoice and guarantee
€8 per letter, €11 per modifier key, €15 for the space bar, flat €3 shipping worldwide. An invoice is issued for every order, and the 30-day money-back guarantee covers any compatibility or quality issue.

Frequently asked questions
Where can I find a replacement key for the Logitech Signature Slim MK955?
▾
MX Keys Parts sells MK955-compatible keys individually, hinge included, from €8, with an invoice and worldwide shipping. Logitech does not distribute separate keys for this combo.
Is the key I receive the official Signature Slim MK955 key?
▾
No. Logitech does not sell individual keys. We ship an MX Keys key that is compatible with the Signature Slim MK955: the scissor mechanism and mounting footprint are identical, the printed design may differ slightly from the original. It fits and works like the key it replaces.
How do I know the key will hold on my Signature Slim MK955?
▾
The mounting is the same across this generation of Logitech slim keyboards: four metal hooks on the plate, a scissor hinge, a cap that clips on top. If your keyboard has flat keys and a scissor mechanism, the key holds. If in doubt, send us a photo of the empty slot and we will identify the part.
Do I need to pick a layout (AZERTY, QWERTY, QWERTZ)?
▾
Yes, for every printed key. Choose the layout printed on your keyboard so the characters match. Unprinted parts — hinges, rubber pads — are universal.
Can I order several keys for a keyboard fleet?
▾
Yes. There is no minimum or maximum quantity, and the €3 shipping is flat for the whole order. For a recurring fleet requirement, describe the parts you need through the custom order form.
Will I get an invoice?
▾
Yes, an invoice is issued for every order and can be filed as an expense or a business purchase.
