Are the 3 hinges in the pack identical?

Yes: they are 3 standard, interchangeable hinges, each for one regular-size key — a letter, a digit or a function-row key — whatever the layout.

Do I need to buy the whole key when only the hinge is broken?

No. As long as the cap is intact and keeps its pegs, it clips back onto a replacement hinge. The whole key is only needed when the cap itself is cracked or damaged.

How do I tell whether it is the hinge or the rubber dome?

The hinge guides the key: when it breaks, the key tilts, goes down crooked or comes off. The rubber dome underneath pushes it back up: when it is damaged, the key feels mushy, returns slowly or stops typing while it still moves normally.

Overview

Set of 3 MX Keys hinges: the X-shaped plastic hinge that sits under an MX Keys keycap and guides its vertical travel. It is the part that breaks most often, well before the cap: a key that goes down crooked, tilts, stops clicking or comes off almost always has a cracked hinge or a torn clip. The set holds 3, enough to repair 3 keys. The hinges are pulled from used MX Keys keyboards we take apart.

Compatibility

The standard hinge fits regular-size keys — letters, digits, the function row — across the whole MX Keys, MX Keys S, MX Keys Mini and MX Keys for Mac family, whatever the layout: AZERTY, QWERTY or QWERTZ, the mechanism under the cap is the same. Wide keys (Shift, Enter, spacebar) have a mechanism of their own: for those, order the key itself, which ships with its own.

When to replace the hinge

The key goes down on one side only, rocks under your finger, no longer clicks or pops off at the slightest touch: that is the hinge. If the cap is intact and still has its pegs, the hinge alone is enough, with no need to buy the key again. If the cap is cracked or has lost a peg, order the key instead: it ships with its hinge. The pack of 3 repairs several keys in one go, or keeps spares in hand: a hinge that is forced can also break while being fitted.

How to fit it

Lift the cap straight up from one corner with a fingernail or a plastic spudger. Clear out what is left of the old hinge, clip the new one flat onto its anchor points, facing the same way as the old one, then set the cap back on and press the centre until it clicks. The repair is purely mechanical: no update, no re-pairing of the keyboard. With several keys to fix, do them one at a time so the caps do not get mixed up.
