Hi

It seems one of my Fatar keys has problem.
Does anyone know how to take out a single key? i googled and watched video of disaamble Fatar keyboards and i opened up and tried to take out a single key but haha i can't make it. i feel i will make it worse. so i need some more explantion.

Or If you know any technician or can help me, please PM me

Thank you

There're some piano technicians near Paya Lebar MRT and try your luck with the uncle selling second hands piano. who repair piano too.
