My keyboard does not connect (BKFC-04)

Hey guys

I've got a mini bluetooth wireless keyboard BKFC-04 but it does not connect to my macbook pro.

First off all my macbook does not see this keyboard but another (something with BCM20730) and if i want to connect this, it's not possible.

In dutch it says: " Koppeling mislukt".

What can i do? I already tried to catch it in my bluetooth settings, but there it gives the same problem.

Help me please!

Thankyou
