The MX Keys spacebar is the most-pressed key on the keyboard, and one of the keys that break most often. Its length (6.25 units) also makes it more fragile because it is held by a metal stabilizer in addition to the standard scissor mechanism. If your MX Keys spacebar is broken, fallen, misaligned or no longer presses evenly, the diagnosis is almost always the same: the plastic scissor hinge is split, sometimes alongside a dislodged stabilizer. The spacebar itself can be replaced individually for €21.90, shipped to 44 countries (3-7 days in France and the EU, up to 4 weeks outside Europe).
Diagnosis
Three typical cases: (1) the spacebar tilts to one side under pressure — one side of the scissor is broken; (2) the spacebar has completely fallen off and cannot be re-clipped — the X-shaped hinge is destroyed; (3) the spacebar sinks but does not return — the metal stabilizer has slipped out of its holders, or the silicone rubber dome is compressed. Most of the time, a replacement MX Keys spacebar, hinge included, solves the problem in under a minute.
How to fix it
- 1
Gently lift the spacebar from one corner with a fingernail or plastic spudger, vertically.
- 2
Inspect both plastic X-shaped hinges under the bar — often only one is broken.
- 3
If the horizontal metal stabilizer has slipped out, fit it back into its two side clips before installing the replacement bar.
- 4
Place the replacement spacebar, align it on both scissors, and press firmly along its full length until you hear the clicks.
FAQ
How much does an MX Keys spacebar cost?
€21.90 each, scissor hinge included. Available for MX Keys, MX Keys S, MX Keys for Mac and MX Keys Mini in AZERTY, QWERTY and QWERTZ layouts.
Is the MX Keys Mini spacebar compatible with the standard MX Keys?
No, the Mini spacebar is shorter (5 units instead of 6.25). Make sure you select the exact model in the catalog.
Is the metal stabilizer sold separately?
No, it is part of the keyboard and normally not a replacement item. If it is broken or lost, contact us via the Contact page for a special request.
Do I need to replace both hinges?
Not necessarily if they are intact. Our spacebar ships with its hinge — you can reuse the other if it is in good condition.
A broken MX Keys spacebar never justifies buying a new €130 keyboard. With €21.90 and under a minute of work, your keyboard regains its original feel.
