About the Fn replacement key
This is a genuine-fit replacement Fn key for the Logitech MX Keys, supplied with its key cap hinge so you can fix a broken, missing or unresponsive key instead of replacing the whole keyboard. Each order is the single Fn key shown — pick exactly the key you need and keep typing in minutes.
Compatibility
This Fn keycap is cut for QWERTY (PT) 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 (PT) layout, so the key you receive is exactly the one printed on your keyboard.
Why the Fn key fails
The Fn 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. Replacing the single key is far cheaper than a new keyboard and takes only a moment.
How to install it
Replacing the Fn 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.
Fn key — questions
- Does this Fn key fit my Logitech MX Keys?
- Yes — it is made for QWERTY (PT) 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 (PT) layout so the printed characters match.
- Is the hinge included with the Fn key?
- Yes. Every Fn 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 Fn 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.
