Left Ctrl key stopped working totally I have been using this keyboard for the last 2 and a half years.


Eventually I noticed that Left Ctrl key stopped working at all. Means, when I push it down in some combination, like Ctrl-T, only T is recognized. Right Ctrl Key works just fine as well as other keys.

Another thing, is sometimes keyboard pushes Alt (Option) down and doesn't release it until I push it multiple times. It event keeps it pushed on reboot so Boot options screen appears on the reboot as if I held Alt key.

I tried it on another Mac and Windows computer, everything seems to be the same.

I am afraid it's hardware is broken, not software. Is there a way to make these keys work, do services repair them or should I rather buy a new one?
I'd be surprised if normal wear &amp; tear would be able to do that in just 30 months or so. I only retired my similar keyboard after about 7 years, when I could no longer read the letters, I'd worn them off.

I'd try tapping the offending keys with greater than usual force, see if something crispy is stuck underneath. After that, I've heard of people having success actually running keyboards under the tap - so long as they are given plenty of time to thoroughly dry out afterwards, though I've never done it myself.
Wouldn't try it with a wireless keyboard, but wired might just be fine.
