Recommended tools for some keys
Optional but handy: the spudger lifts the key without scratching or bending the mechanism, and the thin blade of the flat screwdriver unhooks the plastic hinge and helps clip it back in.

On these keyboards, this genuine MX Keys key takes the place of the official one: same scissor mechanism and mounting, with a legend and finish that may differ slightly.
Where is the F3 key and what does it do?
On a full-size Logitech MX Keys, the F3 key sits on the top row, between F2 and F4. By default it triggers the function drawn on the key; held with Fn, it sends F3, which opens search in many programs. Fn + Esc swaps that behaviour for the whole row.
About the F3 replacement key
The F3 key from the top row of the Logitech MX Keys, supplied with its hinge, to replace a key that cracked, was torn off or got lost. The F3 key is a genuine Logitech part, pre-owned, taken from a dismantled keyboard; the rubber dome is not supplied, as the one on your keyboard stays in place.
Compatibility
This F3 keycap fits the full-size MX Keys (MX Keys, MX Keys S and MX Keys for Mac), not the MX Keys Mini, whose top-row caps are shorter. The legend is that of the QWERTZ (CH) layout. On the MX Keys S, the top-row keys carry different icons, so this key will not match them exactly.
The F3 key: position, size and wear
It carries two markings: a drawn icon in the middle and “F3” in a corner — the two functions Fn switches between. Pressed less often than a letter, the F3 key wears more slowly, but its scissor hinge is just as thin: a fingernail, a cloth or an object resting on the keyboard that catches it sideways can tear a clip off.
How to install it
No tools needed. Lift what is left of the old F3 key by one corner, straight up, clear away any pieces of hinge, clip the supplied hinge flat onto its anchor points, then set the new cap on top and press the centre until it clicks. To test it, try it alone and then with Fn held: one press triggers the drawn function, the other F3.
F3 key — questions
- Where is the F3 key and what does it do?
- On a full-size Logitech MX Keys, the F3 key sits on the top row, between F2 and F4. By default it triggers the function drawn on the key; held with Fn, it sends F3, which opens search in many programs. Fn + Esc swaps that behaviour for the whole row.
- Does this F3 keycap fit my Logitech MX Keys?
- Yes on a full-size MX Keys (MX Keys, MX Keys S and MX Keys for Mac); no on the MX Keys Mini, whose top-row caps are shorter.
- Is the hinge included with the F3 key?
- Yes: cap and hinge arrive together. The dome, the small rubber cup that makes the F3 key spring back, is not part of the order; the one on your keyboard is reused, and a spare dome can be ordered on its own.
- My F3 key triggers its icon instead of F3 (or the other way round) — is it broken?
- No, that is the Fn lock. Hold Fn to get the other function, or press Fn + Esc to swap the behaviour of the whole row. A broken key leans, catches or no longer goes down.
Check your keyboard's brand
You are looking at a Logitech key. Keycap and hinge differ between brands: this key will not fit an Apple keyboard.
