What Is Fairkey?
Ergonomic Instruments – Designed for Professionals, Built for Everyone.
What is Fairkey?
Fairkey builds custom ergonomic piano keyboards — tailored to your hands and built for serious performance.
We offer two main paths:
-
Acoustic upgrades: Replace the keyboard in your upright or grand piano with a fully customized one
-
Digital instrument: A compact, high-end keyboard instrument built with the same Fairkey technology inside
Whether you're upgrading an existing piano or looking for a beautifully designed new one, Fairkey offers a professional, realistic solution — built to play, not to pretend everything’s fine.
What is it that we offer?
How to Order Your Custom Fairkey
Getting the Right Fit Is Easy — and Foolproof
Fairkey is the only system that lets you measure both your hands and your instrument with total accuracy — safely, quickly, and with full support.
No risk to your piano. No stress on your hands.

Measure Your Instrument
(Only for acoustic orders)
We’ll guide you if needed — and set up a shared folder with everything you need.
-
Upright pianos: Can be measured in place
-
Grand pianos: The keyboard and action slide out easily once the cheek blocks and fallboard are removed — a standard, non-invasive procedure any technician can do
-
No shipping required — You never need to send your current keyboard

Place Your Order
Once you’ve chosen your layout and (optionally) measured your hand and instrument, you can place your order in our online store.
We’ll double-check all specs with you before we start building.
