About the Opt / Start (L) replacement key

Bring your keyboard back to life with this exact-fit Opt / Start (L) key for the Logitech MX Keys. The scissor key cap hinge comes in the box, so a cracked, lost or dead key is a one-minute repair rather than a new keyboard. Each order is the single Opt / Start (L) key shown — pick exactly the key you need and keep typing in minutes.

Compatibility

This Opt / Start (L) keycap is cut for QWERTY (IT) keyboards and fits MX Keys (PC) along with the wider MX Keys, MX Keys S, MX Keys Mini and MX Keys for Mac family, which all share the same key profile. The legend and character set match the QWERTY (IT) layout, so the key you receive is exactly the one printed on your keyboard.

Why the Opt / Start (L) key fails

The Opt / Start (L) key is a control key that you hold down and combine with others (think copy, paste, capitals or switching apps). It takes firm, repeated pressure all day long, which makes it one of the most common keys on the MX Keys to wear out or break. Ordering the exact key you need avoids buying a full keycap set you don't want.

How to install it

Replacing the Opt / Start (L) key takes under a minute and needs no tools. Line the new cap up over the white scissor hinge and press straight down until you feel a soft click. The plastic key cap hinge is included, so you can also fix a key that lost its clip — not just the visible cap.

Opt / Start (L) key — questions

Does this Opt / Start (L) key fit my Logitech MX Keys?
Yes — it is made for QWERTY (IT) MX Keys (PC) and the shared MX Keys key profile (MX Keys, MX Keys S, MX Keys Mini and MX Keys for Mac). Just confirm your keyboard uses the QWERTY (IT) layout so the printed characters match.
Is the hinge included with the Opt / Start (L) key?
Yes. Every Opt / Start (L) replacement ships with the scissor key cap hinge and the rubber dome cup, so you can repair a key that lost its clip or no longer springs back — not only a cracked cap.
My Opt / Start (L) key still doesn't work after I replaced the cap — why?
If the key was unresponsive rather than just physically broken, the fault is usually the scissor hinge or the rubber cup underneath. Both are included here, so replace the full mechanism and test again.
