How to fix a squeaking key on the alesis vi49 (and presumably others as well)
Compared to some other gear-repair posts I’ve done, this one is really pretty basic, but as someone who is often trying to repair something for the very first time, I always appreciate if I can find out ahead of time what’s involved and how difficult it is. So in that spirit, here’s a very short how-to.
The good news is that this is a very simple fix: it will take you less than fifteen minutes. All you need is a small-ish Phillips-head screwdriver and some WD-40.
Step 1 (of 3) is to open the case. You do this by unfastening all of the screws on the bottom side of the keyboard. Actually, you probably only need to remove the screws along the perimeter. there are a half-dozen or so screws more in the center of the keyboard, but it doesn’t seem that they connect to the upper housing. I did remove all of the screws and didn’t have a problem, but I’d try just starting with the perimeter screws because I think that’s all you need.
All of the screws are of the same size and length, so you do not need to keep track of which came out of which hole.
Once the screws are removed, lift the housing from the front. Pay attention to the two ribbon cables that connect the lower housing to the upper housing. You do not need to disconnect the cables; they are long enough that you can lift the upper housing with the cables in place.
The squeaking sound you hear when you press your problem key is caused by friction between the key and the spring that provides resistance to your playing (and, of course, returning the key to its starting position). A tiny bit of WD-40 sprayed on the spring should quickly resolve the issue.
Play each key repeatedly and check to make sure it’s not squeaking. If it is, give it a shot of WD-40. Do not overuse the spray.
When all the keys are quiet, lower the upper housing and replace all of the screws you removed in step 1. That’s it. I did have a squeak return after about a year, but this process is so easy I did not really mind repeating it. I suppose you could consider other lubricants if this fix doesn’t last long enough for you, but I have no specific recommendation.
Best of luck!
