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 AZERTY (FR) 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
Fitting takes no tools. If the old hinge under the F3 key is split, remove its fragments; seat the one supplied, hold the new cap flat above it and press the middle — a click tells you it is held. 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.
- Will the F3 key fit my 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, the X-shaped hinge comes with the F3 key — it is often the part that broke. Only the rubber dome is not supplied: it stays in place on the keyboard under the F3 key, and domes are sold in packs among our spare parts.
- 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.
