I have ThinkPad E550 (model 20DF004KRT) without keyboard backlight.
I have installed new keyboard with backlight (model in attached picture).
But it does not turning on: Fn+Space acts like just Space (both in Windows and in BIOS).
Maybe someone knows the solution?

Welcome to Lenovo Community! And happy to have you here.
By looking at the Platform Specifications of ThinkPad E550 it was never released with Backlit keyboard and the MotherBoard of this system doesn't have the required circuitry for Backlit keyboard.
So there is no chance that backlit keyboard will work with your system.
I hope the above information helped you.
