The MX Keys Enter key (Return on Mac models, sometimes labeled ⏎) is one of the three most-used keys on the keyboard, just after the spacebar and Shift. Its specific shape — wide rectangular on AZERTY/QWERTZ, narrow on QWERTY US — makes it sensitive to mechanical stress, especially when struck hard. If your MX Keys Enter key is broken, fallen or no longer presses, it is almost always the scissor mechanism under the key that has split. A new key with hinge costs €11 (modifier category on AZERTY/QWERTZ, €10 standard letter on QWERTY US).
Diagnostic
Main symptoms: (1) the Enter key falls at the slightest movement — the X-shaped hinge is broken and no longer holds in the metal hooks; (2) the key sinks but does not return — the silicone rubber dome is compressed or the scissor is bent; (3) the key clicks but no character is typed — this is a membrane contact issue, rarer, and may require disassembling the keyboard. Check the scissor visually first.
Méthode
- 1
Lift the Enter key vertically with a fingernail or plastic spudger.
- 2
If the X-shaped hinge is broken, remove the fragments from the four metal hooks on the plate.
- 3
Clip the new hinge that ships with the replacement key.
- 4
Place the Enter key, align it in its slot (notably on AZERTY where it is an inverted L shape), and press firmly until the click.
FAQ
Is the AZERTY Enter key compatible with the QWERTY version?
No, the physical shape differs: AZERTY/QWERTZ Enter is an inverted L spanning two rows, QWERTY US Enter is a standard single-row key. Check your layout before ordering.
How long does the replacement take?
Under a minute, no mandatory tool (a fingernail is enough). The keyboard works immediately, no restart required.
My Enter key clicks but nothing is typed — is it the keycap?
Probably not. If the mechanical click is there without text input, the problem is on the membrane below the rubber dome, requiring opening the keyboard. Contact us via the Contact page for a workshop diagnosis.
A broken MX Keys Enter key is replaced for €11 in under a minute. No justification to replace the whole keyboard.
