I need a way to use my keyboard on a computer in the lounge (its to far away for me to use synergy)

Something like, If i press numpad 1 I need the other pc to press number 1, if i press numpad 2 i need it to press K... and some more.
What are you actually trying to do?

It seems clear to me that you're want some simple key-mapping functionality, which lots of software can provide (including HKN and Keyclone) but what throws me is your "it's too far away for me to use synergy" comment.

What do you mean, and what's your exact setup?
