Will this [ / { keycap fit my MX Keys S?

Yes, whichever version you have: this [ / { keycap is a one-unit cap shared by the MX Keys, MX Keys S, MX Keys Mini and MX Keys for Mac. Just check that your keyboard uses the QWERTY (US) layout, so the printed characters match.

Is the hinge included with the [ / { key?

Yes: cap and hinge arrive together. The dome, the small rubber cup that makes the [ / { 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 [ / { key still doesn't work after I replaced the cap — why?

First try the [ / { key on another computer or in another program, to rule out a setting. If it stays silent, look under the cap: with a split hinge it moves crooked; with a crushed or loose dome it goes down without typing.

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.

About the [ / { replacement key

A [ / { key for the Logitech MX Keys, with its hinge: the exact punctuation of your layout, to replace a key that broke or went missing. Genuine Logitech and pre-owned, the [ / { key was removed from another keyboard; only the rubber dome is not included.

Compatibility

This [ / { keycap is a one-unit cap from the alphanumeric block: it clips onto the MX Keys, MX Keys S, MX Keys Mini and MX Keys for Mac, which all use the same key size across that block. Only the legend changes from one layout to another; this one is QWERTY (US).

The [ / { key: position, size and wear

On the full-size MX Keys, the [ / { key sits on the top letter row, just below the digits, 2nd key to the left of Enter. In touch typing, it belongs to the right little finger. Its legend, “[ / {”, belongs to the QWERTY (US) layout; physically, a symbol key from another layout has the same shape, but it would print the wrong characters. With no metal wire under a one-unit cap, the [ / { key rests entirely on its scissor hinge. A press at an angle, a fingernail slipped underneath or a vigorous clean is enough to tear one of its clips.

How to install it

Allow under a minute to refit the [ / { key, bare-handed or with a plastic spudger: free the old hinge if it is broken, clip the new one in the same orientation, then press straight down on the cap until you feel a soft click.
