Why is replacement keyboard malfunctioning?

본문:

I have replaced the keyboard and keyboard backlight on this machine. The backlight comes on.

BUT, now the replacement keyboard will not register most letters and numbers. Many keys will cause a  system clunk sound when pressed.

I have to connect an external keyboard to log into my account. Since the keyboard will not register letters properly, I cannot do CMD-OPT-P-R + Power Button to reset the NVRAM, of start with D held down for hardware test.

Is it possible that the keyboard requires a different firmware version than the one on the machine? This machine is running OSX 10.5.8 (I have not upgraded because I have a ton of costly software on it. One 3D modeling and rendering package is not in existence anymore. It is a good program, so no upgrade to OS)
