If you're wanting to remove keys, you'll most likely find yourself faced with a strip of rubber dome switches. You'd then have to remove all of the keys and pull off the silicone rubber strip. You may only be able to re-attach it from the back.
I don't have an EM2000, nor do I know how they work, this is only my best guess based on what is most commonly used for modern keyboards. I can't really be much of a guide, so do some careful exploration and adjust your approach accordingly.

Hi Francois and anyone else who may
know,
Thanks for all the info so
far. I have finally had time to take the Roland apart. I was hoping
that just blowing it out might make my couple of keys start working!
LOL.......
but NO........... So I removed the
keyboard and looked it over. There is an electronic board screwed to the
underside and nothing to really see. It appears I have two choices at this
point.... to disconnect the electronic board under the keys or try to
remove just the keys that are not working. I see that there is a spring
behind each key and it appears that if I remove the spring, it should be able to
move slightly forward and disengage from a "catch" of sorts that is towards the
front of the key which holds it down and in place...........
What say you?...........On one
hand, removing the entire under board will give me a look-see at all the
contacts (I think)...however, is there a trick to this?....does anyone
know?
The other question would be if I
DID decide to remove just a key at a time, any suggestions for removing the
springs? Looks like each spring is situated in a guide that locks it
in...... My approach would be to put a narrow row through it and "pop" it
out?.........sound right?
Thanks all
Adele (and a VERY pretty name
your daughter has, Francois!! LOL....You are French I am assuming?....... In an
effort to find where that name actually comes from, I've asked all of the
Adele's I've met in my life what their heritage is........probably only 7 or
8.......non of which have heritage from the same place.........but this would
make two that would be French.... I am half Italian and part German and a few
other things....... so really don't know where though I was occasionally called
Adelina by my Italian family..)

if no pattern can be found on dead keys, it really sounds like more an oxydation issue than a connector/bus trouble. Was your keyboard stored in a moistured place? I've never opened this keyboard, so my advice might be not fully applicable.
- use a large workspace away from kids and pets and be prepared to use it for a couple of days.
- get a bunch of small plastic contents to store the screws while opening the case. Don't mix screws.
- if you don't have the right screwdriver, buy a good one. A cheap ;or wrong screwdriver will ruin your screws.
- if you have a digital camera, taking step-by-step pictures. Useful when reclosing the case.
- Once all screws removed, take care when you open the case: there might be a ground wire (green).
- it's better to remove the keyboard from the case. However, it could means removing a couple of other boards. Your judgement will guide you.
- take pictures of connectors position before removing them. Some could be rather tough to remove; your fingertips could be painfull after then. Don't use excessive force nor unadapted tools (pliers).
- avoid touching ICs; some are fragile enough to be harmed by ESD (electrostatic discharge). Being grounded is also a good idea.
- contacts could be de-oxyded with a QTip and a dedicated product such as Caig Deoxit. When really oxyded, I sometimes scrub with toothpaste/toothbrush and thoroughly clean the residue.
- reclosing the case is straightforward.
Hope this helps
François

Hope it is ok to ask for help here.
My keyboard had been sitting a while and a couple of keys weren't
working. I was able to get them going by striking the keys a number
of times and all was well.
The keyboard was sitting for a while longer and a couple different
keys stopped working, not the same keys. Unfortunately, I cannot get
the keys to work by that same method.
I would like to open it and see what is going on...dust, oxidation,
rust, wear.....
I did check all the keys now and have found no pattern so I believe it
is not an electronic issue. Here is what is not working:
Octave 1 F# and A; Octave 2 C# and E; Octave 4 B; Octave 5 Eb
I haven't been able to find a service manual and there are MANY screws
on the bottom to open this. Any tricks or warnings? I have done
computer/electronic repair before so not too worried.....On the other
hand, I don't want to destroy anything else.
Second question is if it is just the contacts, any economical
suggestions besides replacing them?
Thanks very much........
Adele
