Hi Leo,
Your easiest first option is to try powering the keyboard with 3.3V some will work, some not, I've so far been lucky. Next you could try reducing the 5V to the keyboard with a couple of silicone diodes in series (1N4001 or2 or3 ,almost anything) , each diode had approx 0.6V drop, so that would be about 3.8V to the keyboard, next try just one diode.
This had been discussed before if you have a hunt around.
Regards Kevin.
