Every MX Keys owner asks this when a key breaks: should I order a €10 part or just buy a new keyboard? The answer depends on the number of failed keys, the keyboard's age and your relationship with electronic waste. This comparison breaks down real costs and tipping points.
Verdict
Repairing is almost always worth it up to 7-8 broken keys (~€70). Beyond that, compare with a refurbished keyboard at €70-100. For motherboard/battery failures, repair stays very cost-effective. For structural damage (bent plate, major impact), buying new is safer.
FAQ
How many years does an MX Keys last before the first failure?
In normal use (40 h/week), 4 to 6 years before the first broken key, 5 to 7 years before end-of-life battery. The motherboard typically lasts 8-10 years.
What is the carbon footprint of an MX Keys?
Per Logitech estimates (2023 report), an MX Keys represents about 3-4 kg CO₂ equivalent across production, transport and end-of-life. Repairing avoids this footprint.
If my Logitech warranty is still active, should I repair myself?
No. If the keyboard is under 2 years old and the failure is not due to misuse, contact Logitech support first. Self-repair may void the warranty.
