MX Keys arrow keys (↑ ↓ ← →) are smaller than average (1U size) and placed in a half-row, which makes them more exposed to lateral impacts and therefore more likely to break. If one of your MX Keys arrow keys is broken, fallen or no longer presses, it is almost always the scissor hinge that has failed. Each arrow key is ordered individually (€8 standard category) with its hinge included. To save time, you can order all four arrows together if several are fragile.
Diagnostic
Identify which direction is failing: up, down, left or right. Typical symptoms: the key falls at the slightest impact — the hinge is broken; the key sits crooked compared to the other three — one of the four clips has slipped; the arrow no longer responds when pressed — first check that it really is the keycap and not firmware (try on another OS). In 95% of cases it is mechanical and a new hinge solves it.

FAQ
Are the four arrows physically identical except for the printed character?
Yes, the four MX Keys arrow keys have the same dimensions (1U) and profile. Only the printed symbol differs. You can theoretically swap a working arrow into the broken position to test whether the key or matrix is at fault.
Can I swap an up arrow with the one from an MX Keys Mini?
Yes, MX Keys and MX Keys Mini arrow keys share the same scissor profile. Just check the color (graphite/white) to match visually.
Are the arrows sold as a pack of 4?
You can order 4 arrow keys separately in a single order. The volume discount applies automatically from 4 keys onwards.
A broken MX Keys arrow key is replaced for €8 in under a minute. No need to buy a new keyboard for a single arrow.
