How do you replace keys

Hi,

There are 3 different types of key fixing, can you let me know the model number and I will be able to offer you some ideas.

There is a well documented problem that occurs with the keybed on some of these models due to a manufacturing fault. Take a look at the keys that are sticking. Is the gap on either side of the key the same ? If not then the key normally leans slightly to the left rubbing on the adjacent key causing the sluggish action. The fixing tab at the back of the key breaks causing the spring pressure to push sideways.

You can just replace the offending key but the problem will eventually return. You could replace the whole keybed but this is a very expensive fix.

Keys are around £ 15.00 each.
Replacement keybeds around £ 450.00

What do you mean by applied graphite...graphite powder? That is not the solution I wouldn't think, you need to use a keyboard contact repair kit, which has a solution you paint on? Something like the link provided might be in order. Make sure there are no improper conductive bridges formed between the contacts in the PCB board surfaces. Replacement rubber pads (the part that presses down) are available from any decent service provider (try Syntaur if can't find http://syntaur.com/korg_x.html ) (beneath key) Korg Key Contact Repair Kit Replacement Keys and Parts for Korg Series Keyboards

You will need to gain access to the keybed, remove screw from back of keybed the fix it to the base of the keyboard. Slide the keybed back making a gap of about 2cm at the front of the keybed.

Look at the back of the key towards where it pivots and you will see a small arrow, push something like a credit card between the keys at this point and the key will pop up, you can then slide forward releasing the key.

If you need more info please ask.

A YDP uses the same key type as a basic Yamaha Clavinova. As you have stripped the keyboard to reveal the keys take a look at the end where the key hinges. There will be an arrow pointing to one side. You will need to remove att the screws holding the key base (black plastic ) to the wooden base. Slide the whole keyboard back a couple of inches, push down where the arrow points between the keys, the offending key will pop up. Slide forward and jiggle out. Replace key. reassemble. If the tag on the back of the old key has snapped off remove the piece of debris that might be there before refitting.

I can think of two places. eBay search for
Casio LIGHTED KEY KEYBOARD or call casio and explain to them what happened and see if they can help :) Steven.

I just fixed my CDP 100 which had a similar problem - dropped and two keys not working up one end.
1. Lay keyboard upside down on soft surface. Under keyboard is plastic cover held on by 17 screws. Remove all these and lift cover away. The metal key ends are all revealed.
2. Locate the disloged keys. Carefully press them back into position - they will "click" into place. Make sure the corresponding key on the keyboard isn't stuck in an "up" position - you may have to remove the metal key part and replace it again while making sure the key is correctly seated.
3. Replace cover and screws.

Most keyboards of that scale are not especially fragile. You may have to remove the back (lots of screws) and maybe a bezel that is across the top of the keys to get full access to the keys. The good thing is you have lots of working models --- all the other keys. So carefully consider the differences. It may be that one or more plastic parts have broken, particularly if it fell and landed with pressure on that key.

Most of the keyboard manufacturers have parts departments that can supply just the part of the keyboard you need if you can specify exactly what you want.

I've had the very same problem twice so far. The only solution I figured is to simpy purchase an equivalent key (contact Yamaha service in your country for this) and to replace the broken one. The reason why the key doesn't work smoothly as the other one is not dirt therefore any cleaning won't help. The key is cracked deep in the place where it's attached to its 'axis'. So you'll need to remove all the screws and unmount the cover (it needs a sideshift to open once the screws are removed), be careful with the speaker wires. However you'll need firm moves anyway. Opening is tricky and gets me surprised anytime I do it so you'll need some courage :). Replacing the key is even more tricky. You'll have to remove the broken one by pulling it horizontaly (use some force, it's broken anyway). Placing a new key you'll need to uplift the 'hammer' and then slide a new one. I'm sure you'll figure it out once you see it with your own eyes (it's really hard to decribe but not so hard to do it). Hope you'll do fine. I haven't tried glueing the crack for I doubt it would work for long. Good luck!
