Replacement keys for the Logitech Signature Slim Solar+ K980
The Signature Slim Solar+ K980 charges from light: it is designed never to be thrown away over a battery. A broken key should not write it off either. We sell keys individually, hinge included, from €8.
Which key do you receive?
For the Signature Slim Solar+ K980 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 Solar+ K980 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.
A keyboard built to last deserves spare parts
The Solar+ K980 recharges from ambient light, including artificial light: longevity is the product's whole argument, no battery to replace. The key, though, remains a wear part — it is the few millimetres of plastic hinge under the cap that eventually split. With no spare part available, a keyboard sold to last ends up in the bin over that single hinge.
Same mechanics as the Signature Slim range
The K980 belongs to the Signature Slim range: flat keys, scissor mechanism, a mounting footprint shared with the MX Keys family. That is what lets a compatible MX Keys key take the place of the original. If your unit has a particular legend or shade, send us a photo before ordering and we will confirm the match.
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.
Per-key pricing and shipping
A letter key costs €8, a modifier key (Shift, Ctrl, Alt, Tab, Caps Lock) €11, the space bar €15. Shipping is a flat €3 worldwide. You buy only the key you are missing — no full keycap set, no €130 replacement keyboard. 30-day money-back guarantee.

Frequently asked questions
Where can I buy a replacement key for the Logitech Signature Slim Solar+ K980?
▾
MX Keys Parts sells K980-compatible keys individually, hinge included, from €8, shipped worldwide. Logitech does not sell separate keys for this keyboard.
Is the key I receive the official Signature Slim Solar+ K980 key?
▾
No. Logitech does not sell individual keys. We ship an MX Keys key that is compatible with the Signature Slim Solar+ K980: 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 Solar+ K980?
▾
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.
Does replacing a key affect solar charging?
▾
No. The photovoltaic cell is built into the keyboard shell, not into the keys. Fitting a replacement cap touches neither the cell, the battery nor the electronics: charging works exactly as before.
How much does a K980 key cost?
▾
€8 for a letter or number, €11 for a modifier key, €15 for the space bar, plus flat €3 shipping.
