Does this Cmd / Alt (L) key fit my Logitech MX Keys?

Yes — it is made for QWERTY (UK) MX Keys (PC) and the shared MX Keys key profile (MX Keys, MX Keys S and MX Keys for Mac). Just confirm your keyboard uses the QWERTY (UK) layout so the printed characters match.

Is the hinge included with the Cmd / Alt (L) key?

Yes. Every Cmd / Alt (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 Cmd / Alt (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.

About the Cmd / Alt (L) replacement key

Lost or broke the Cmd / Alt (L) key on your Logitech MX Keys? This is the precise replacement, hinge included — far cheaper and faster than buying a whole new keyboard. Each order is the single Cmd / Alt (L) key shown — pick exactly the key you need and keep typing in minutes.

Compatibility

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

Why the Cmd / Alt (L) key fails

The Cmd / Alt (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 Logitech MX Keys to wear out or break. Swapping just this one key is the quick, low-cost fix most owners are looking for.

How to install it

Replacing the Cmd / Alt (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.
