Common Keyboard Manufacturers & Their Key Scissors:
- Chicony – one of the largest suppliers, found in many Dell, HP, and Lenovo laptops. Uses a distinct scissor design.
- Sunrex – common in Acer, Asus, and some HP models. Their scissor mechanism has a unique hinge shape.
- Darfon – often used in Dell and Apple keyboards. Known for a particular scissor pivot design.
- Alps – older laptops, but still found in some business models. Their scissor mechanism is taller.
- Lite-On – used in many gaming laptops, often paired with RGB backlighting.
- Primax – common in low‑cost laptops, simple scissor design.
- NMB (Minebea) – premium keyboards, often found in high‑end business laptops like older ThinkPads.
Keycap Compatibility – Critical Info!
- Keycaps from different manufacturers are NOT interchangeable – even if they look similar, the scissor hinge and mounting clips differ.
- If you are replacing the entire keyboard assembly, you don't need to worry about this – the new keyboard comes with its own keycaps already attached.
- If you are buying individual keycaps (e.g., to replace a broken key), you must order keycaps from the same manufacturer that made your original keyboard.
- How to check the manufacturer? Look for a sticker on the back of the keyboard (visible after removal) – it usually has a brand name or a manufacturer code (e.g., “CHICONY”, “SUNREX”, “DF” for Darfon, etc.).
- If you are unsure, contact us before ordering – provide a clear photo of the keycap underside (showing the scissor mechanism). We will identify the manufacturer and confirm compatibility.
Key Travel (Stroke Length) & Typing Feel:
- Key travel varies significantly between different keyboard designs and manufacturers.
- ThinkPad keyboards typically have longer key travel (1.8‑2.0 mm) – providing a deep, tactile feedback loved by typists.
- Ultra‑thin laptops (e.g., MacBook, Dell XPS) often have very short travel (1.2‑1.5 mm) – resulting in a shallow, crisp feel.
- Mechanical keyboards have even longer travel (2.0‑4.0 mm) with distinct tactile or clicky feedback, but they are not used in laptops (external only).
- Key travel is determined by the scissor mechanism design – different manufacturers and series produce different travel distances.
- When replacing a keyboard, consider if you prefer a longer, softer travel or a shorter, snappier feel. The same laptop model may have multiple keyboard variants with different travel depending on the supplier.
How to Identify Your Keyboard Manufacturer & Key Travel:
- Check the keyboard sticker (usually on the back of the keyboard or on the ribbon cable) – it often shows the brand (e.g., Chicony, Sunrex).
- Remove a keycap carefully – take a photo of the scissor mechanism and the keycap underside, then send it to us for identification.
- Search your laptop model + "keyboard manufacturer" online – many forums have discussions about which suppliers are used.
- Compare the key travel depth by gently pressing a key – longer travel feels more cushioned, shorter travel feels more shallow.
Need help identifying your keyboard? Send us a clear photo of the keyboard back sticker and a close‑up of the keycap underside (with the scissor visible). We'll confirm the manufacturer and recommend the correct parts. For custom orders, email us at email.
