Logitech K120 Keys (V, Z, Spacebar) Randomly Stop Working While Playing Valorant - Cleaned, but Issue Persists

Suyash Kerkar · June 18

I'm hoping someone can shed some light on a strange issue I'm having with my trusty old Logitech K120 keyboard. It's about 4-5 years old and has been a reliable workhorse, especially for gaming. Currently, I'm primarily using it for playing Valorant on my laptop.

The problem started a few days ago, seemingly out of nowhere. While playing Valorant, the 'V', 'Z', and 'Spacebar' keys will suddenly stop responding after using the keyboard for a short while. What's particularly odd is that the keyboard remains perfectly still on my desk – I'm not moving it around or putting any strain on the cable.

Here's what I've done so far:

Thorough Cleaning: I've completely opened up the keyboard, removed all the keys, and meticulously cleaned under the keycaps, the membrane layers, and the PCB contact points. There was no visible dust, dirt, or spills, and everything looked to be in great condition internally.
Inspected Cable: The USB cable appears to be in good shape, with no visible kinks or damage.

Despite the cleaning, the issue persists. The keys will work fine for a period, and then suddenly become unresponsive, making it impossible to play Valorant effectively (as you can imagine, 'V' for ultimate, 'Z' for ability, and 'Space' for jump are pretty crucial!). Other keys continue to function normally when this happens.

My laptop's built-in keyboard works perfectly, so I don't think it's a software or driver issue on the laptop's side. It really seems to be isolated to the K120.

Laptop OS: [Your Laptop's Operating System, e.g., Windows 10, Windows 11]

Has anyone experienced similar intermittent issues with a Logitech K120 or a membrane keyboard of similar age? Could it be a subtle cable issue that's not externally visible, a failing contact point on the membrane itself, or perhaps something else entirely?

Any troubleshooting steps or insights would be greatly appreciated! I'd love to save this keyboard if possible, as it's been fantastic.

Thanks in advance for your help!
