Tacky keys

Post by protek » 08 Mar 2017 11:18

The keyboard in my MTX 500 seems to be working otherwise, but some of the keys are quite tacky, so that they won't go down, if you don't ease it by wiggling it with the tip of your finger.

Is there any way to make the keyposts in the switches move more smoothly? Does it just require a thorough clean?

Thanks, Dave!

So, canned air and IPA in a spray can should do the trick.

Actually, it's more just exercising the keys.

Really work them hard, many many times, they will get better with LOTS of use.

You should be able to recover most, if not all of them, if one or two are beyond help, then you can replace the key as described on this page
