I'm looking for the rubber boot key contacts for a Roland RD300s. Roland doesn't make them any more. I cannabalized the highest octave a few years ago to fix the ones in the middle octave but now they're breaking as well.

Damage to the contact rubber can cause note plays loudly or,
note does not plays at all. It is caused by: 1. Carbon rubber contacts dirty / dusty (yellow arrow). Clean with a pencil eraser (or cloth). Gently rub it.
2. Contact rubber is torn (your case). If this happen,it can not be repaired or glue. So, you have to replace one octave.
The yellow arrow indicates the side that is often torn.
Rubber side that is torn, usually not seen, unless we move / pressing gently on top (In the rubber contact position is not installed on the board.)

Hi, You can reset your whole keyboard by holding down the top C ( highest key ) whilst turning on.
This is unlikely to clear 3 non working keys. My guess is that the contacts under the rubber switches have worn or dust is under the contacts. You could try cleaning first under the rubber contacts if this fails replace the contacts ( 1 per octave ) Part WF212202 contact me if you need more information
DUST on sensors! If you have steady hand, you can remove the entire keyboard. Using a computer vacuum cleaner, clean the sensors on the instrument, then replace the keyboard carefully. Or, take it to a technician to have the keyboard sensors cleaned.
One of the lines in the keyboard scanner has opened up. I have an idea what it might be and it is a nasty problem involving circuit traces that are silver conductive paint on a plastic insulating base that separate from a jumper at each end of the strip that the key contacts are made by conductive rubber pills pressed down by the keys. The contact of the flexible circuit under the keys to the jumper cable can be broken by vibration. I have an EPS7 with the problem and other than replacing the whole contact strip under the keys it really has no easy solution.You should probably have a Roland shop look at this problem. If your unit has this same arrangement it is repairable only by replacing the whole key contact strip.
The key contacts have become contaminated. Disaasemble and find the contacts under silicone rubber domes. They are typically black conductive rubber pills, two per key. Clean them and the circuit traces they press against under them with ONLY 99% isoprophyl alcohol and Q Tips GENTLY. Then reassemble and test operation.
The key contacts need to be cleaned. They are usually conductive rubber pills in silicone domes that get pressed onto circuitboard traces by the keys. Disassemble to get at the contacts. clean ONLY with 99% isoprophyl alocohol and Q tips. Clean both the pills AND the circuit traces they contact.
Be very careful of cables when opening the unit. Document where all the screws go and their length and threads.
Answer: Before i give you the right solution, i have to say that i have posted the answer to FIX the problem of all of the contact problems, people writing in how many of their keys are not working. And the post that they are showing is one that says to clean the contacts. That will not work. Ok, the answer..... You can purchase a kit called Rubber contact kit here: http://www.mcmelectronics.com/product/20-3890&cid=prodCrossSell or Key contact Kit: http://www.oaktreeent.com/Roland_Keyboard_Parts_Units.htm
These kit are made to re-coat the contacts on the keys. It will bring your board back to brand new condition and last as long if not longer than the original coating. Also can be used for any rubber contacts like remotes or game controllers. etc. This will work and i did mine after numerous times of taking the keys off and cleaning them. I hope this gets out to all of you that are having the same problem. Good luck
