Lost Receiver of my wireless keyboard any solution?

Hi,

I have bought a logitech MK295 wireless silent keyboard & mouse. Sadly I lost my mouse and receiver of it. Now I have a wireless keyboard which I can not use.

I read that a unifying logitech receiver wont work on this model. So how else can I use this keyboard? I contacted logitech support, an employer told me that tthe MK270 receiver is the same as the MK295, but the next day I received an Email of Logitech that it doesnt work.

So is there a solution? Is there a way to use this wireless keyboard? To give it a new life, because otherwise it is just a waste. And I dont want to throw it away.
