Key presses registering twice - help

[NewGamer11]

I've got a mechanical keyboard at the moment and I'm starting to have a problem with one the keys, the 'T', registering twice when I press it. It happens fairly often which is annoying. Also starting to happen with the 'P' too.

I've had the keys off and cleaned around them but is there anything else I can do to fix this?

This is called " key chattering " and usually happens with Cherry MX mechanical keys. Either something (dirt, dust, hair, ash, plastic dust, ...) gets inside the MX switch or it simply comes "of age" AND the switch starts to register as a double-click (but not each time). Sometimes it takes a year, sometimes less. It's a wide-spread issue. Following might help.

• Sometimes cleaning the switch (while pressed) with compressed (canned) air can help (probably removes dust).
• Sometimes a few drops of Isopropyl alcohol (80% or stronger) and pressing the key rapidly makes the problem go away for a few weeks or even months. Press down switch with small tiny screwdriver and apply alcohol with q-tip.
  
• In a few rare cases using electronic silicone lubricant and lubricating the switch helps.
• If it happens on more than 1 key it might be the controler firmware (gone bad) or a driver conflict.
• Alternatively you can buy replacement switches, desolder old switches, re-solder new switches.

There is also a utility which advertises itself fixing these issues but i havent tried it...

Thanks @BaroUK2. I’ll certainly give the first two a try. It is a couple of years old now.
