Fixing Dead Keys on a Musical Keyboard

I'm going through the process of me fixing dead keys on an Akai MPK Mini Keyboard. I plan to use this keyboard to help me compose an original intro song for the channel. Here's a quick run down of what I did.
-Opened up the keyboard
-Clean the PCB contacts for the keys. I used a cotton swab dipped in 90-100% Isopropyl alcohol
-Dried out the keyboard
-Reassembled it.
Hope you find this video helpful

Thank you so much. Three keys weren't working: the keys under EXCL, INCL and SING 61%. Your thorough walk through on how to fix helped. Now all keys work!

Put me to think, I have an old PRS-70 with a mum key, the challenge is to take it apart, done that, I should be something easy to do, thank you for the video; especially useful and encouraging

bro I had my mk mini2 for many years with dead keys and i was getting ready to toss it out. I decided to try this figure i had nothing to lose even if it messed up on the process and the keys worked after cleaning it lol. wow

Thank you man so much. Btw if you use isopropyl alcohol do don't have to wait one hour, it evaporates instantly XD

My key under 1/4 takes multiple presses for it to respond. Shall I proceed with this?

[@Ramon_Beats]

Thank you for video. I made all what you show. But what is the reason of this problem¿ why it’s happening?

[@lustechsource5197]

I honestly don't know the exact reason, but this happens with other electronics after they age for a while.

Hello friend, what program do you try to test the keyboard?

[@lustechsource5197]

I used FL Studio Mobile on my Chromebook.

[@SapMusiq]

can i use dettol instead of isoprophyl alcohol

[@lustechsource5197]

I don't know what dettol is. I'm not an expert at this I just use what I know.

[@RJGAMEZ-vu4zv]

Is that a Chromebook? If so, what software is it?

[@mateuszgogulski5641]

1:10000000000 chance, that the same keys will die in 2 separate devices - but guess what... same keys are dead in mine MPK - thanks for this video!

[@lustechsource5197]

Ha ha! Glad this video helped!
