Dell Latitude E5520 backlit keyboard upgrade

Recently purchased a backlit keyboard to replace my non backlit one. It's supposed to be supported but the keyboard does not function at all.

Any assistance is greatly appreciated.

Is the keyboard itself not working, or is it the backlight that isn't working?

If it's the backlight, is the Dell ControlPoint software loaded?

The replacement keyboard which is backlit does not function or is recognized by the system. The old non backlit keyboard worked.

I've even hooked up a USB keyboard and made sure to uninstal the keyboard driver just in case when I installed the new keyboard so the system would detect a new price of hardware.

If the original keyboard works when reinstalled, the new one is fault.  If it doesn't, check the cable that connects the keyboard to the mainboard for damage - it is very easy to damage these (or the mainboard connector, which hopefully didn't happen) when you replace a keyboard.
