The Logitech K380 (920-007580) is Logitech's best-selling compact mobile keyboard. Important: it does NOT use the MX Keys scissor mechanism — it's a simple membrane keyboard with deeper round keys. This makes K380 keys incompatible with all other catalog parts. We carry K380 keys individually at a lower price (€5 vs €8-15 for MX Keys).
Diagnostic
Recognizing a K380: very visible individual round keys, very compact layout (no numpad), 3 Easy-Switch buttons on top, available in many colors (black, pink, blue, white). The membrane mechanism makes it more liquid-tolerant but less precise than scissor. Keys harder to clip due to round shape.
Méthode
- 1
Confirm it's a K380 and not an MX Keys (round vs flat keys).
- 2
Order a K380 key from the dedicated section — not an MX Keys (different mechanism).
- 3
Lift the broken key (harder than MX Keys due to round shape).
- 4
Place the new K380 key, press firmly at center — there's no scissor hinge to replace (membrane).
FAQ
Is the K380 as durable as MX Keys?
Differently. K380 membrane mechanism is more liquid-tolerant (spills, splashes), but less comfortable for long typing sessions. Key lifespan: 10 million cycles per Logitech (vs 20 million for MX Keys scissor).
Why are K380 keys cheaper?
Membrane mechanism is less complex to produce than scissor (no X hinge, no fine mechanics). We sell K380 at €5 each vs €8-15 for MX Keys keys. Limited stock by color.
Can I replace a K380 key with an MX Keys?
No, totally incompatible: different shapes (round vs flat), different mechanisms (membrane vs scissor), different profiles (deep concave vs slight concave). Don't even try, you'll damage the keyboard.
K380 = membrane mechanism = K380-specific keys only. €5 each, much cheaper than MX Keys but order from the dedicated K380 section.
