PC keyboard duplicates space keystrokes

[ijor]

My PC keyboard suddenly started to repeat space keystrokes. Whenever I hit the space bar, it produces two (sometimes three) spaces. I read that this mean that it likely needs some cleaning. Ok, so I remove the space bar and perform a quick cleanup of the area and the bar itself. It works ok ... for a couple of days, may be more, but then it starts again. Clean again, some story, works ok only for a few days.

Time to change the keyboard? A major cleanup removing all the keys?

I don't know what the mechanicals are like of your keyboard but I have used contact cleaner in the past to avoid a full strip-down. Just test it first to make sure it dries non-greasy but it should.

Whilst the mechanicals can get sticky, it's possible that you'll need to go a bit deeper and look at the the key switch, be it a membrane, rubber dome or mechanical switch. For membrane and rubber dome I find that a clean with IPA is usually enough, but for mechanical switches you probably need some sort of contact cleaner like DeOxit or Electrolube.

If it is a USB keyboard I would certainly spray some contact cleaner on the USB socket and plug or try a different USB socket. I've been "had" of thinking I have a faulty keyboard when it was simply a bad connection.

Thanks for the replies.

It's a mechanical keyboard, not an expensive gamer keyboard, but not a very cheap keyboard either:

Edit: For some reason a link to Amazon doesn't work.

Probably a squirt of contact cleaner in the switch would do then.

For doing that I would need to remove the switch, right?

Thats because of HTTPS links are not allowed across different domains. If you remove HTTPS, it should work fine.

Depends on the switch, some do allow a little access with the keycaps removed and the stem depressed, others may need removal.
