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

Yes, if it is a full-size MX Keys (MX Keys, MX Keys S and MX Keys for Mac) in the QWERTZ (CH) layout: the Cmd / Alt (L) key has exactly this shape there. Not on the MX Keys Mini, where Ctrl and both Cmd / Alt keys are narrower (1.125 units).

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

Yes. The hinge travels in the parcel with the Cmd / Alt (L) key, ready to fit; what you will not find is the rubber dome, which never leaves your keyboard and is sold separately if needed.

My Cmd / Alt (L) key feels loose or uneven after fitting — what should I check?

Take the Cmd / Alt (L) cap off again and check that the hinge is clipped onto all its anchor points; if a metal wire sits under the key, make sure it is engaged in its clips. Then press the centre of the Cmd / Alt (L) key before its ends.

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.

Compatible with these Logitech keyboards

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 Alt key and what does it do?

On a full-size Logitech MX Keys, the Alt key sits on the bottom row, between the Windows key and the space bar. In Windows it forms Alt + Tab (switch window) or Alt + F4 (close the active window). On a Mac it becomes Command (⌘), hence its dual legend “cmd | alt”.

About the Cmd / Alt (L) replacement key

A replacement Cmd / Alt (L) key for the Logitech MX Keys, supplied with its hinge: a key used all day long, replaced on its own rather than with a new keyboard. We take the Cmd / Alt (L) key from dismantled keyboards: it is a genuine, pre-owned Logitech cap, sold without the dome.

Compatibility

This Cmd / Alt (L) keycap fits the full-size MX Keys (MX Keys, MX Keys S and MX Keys for Mac) in the QWERTZ (CH) layout. On the MX Keys Mini, Ctrl and both Cmd / Alt keys are only 1.125 units wide, so this cap does not fit there.

The Cmd / Alt (L) key: position, size and wear

The Cmd / Alt (L) key is 1.25 units wide, a unit being the width of a letter key. It is often held by the left thumb, on its inner edge, for an Alt + Tab. On a cap this wide, an off-centre press loads only one side of the scissor hinge: that side is the one that splits, and the Cmd / Alt (L) key then leans towards it or catches.

How to install it

Lift the old Cmd / Alt (L) cap by a corner, remove the damaged hinge and clip in the one supplied. Lay the Cmd / Alt (L) key flat, then press the centre and each end: on a key wider than a letter, one side left unseated makes it lean.
