I have a 2 UTP cables that is goind like 15 meters from the central hub in my house to the outer door.
There must be a keyboard(Keypad - 12 Button - COM-14662 - SparkFun Electronics). and i was thinking can i wire it without using controller or media converter on the keyboard side?
And also if it can be done how can i group the twisted pairs not to cross talk and etc
All ideas are welcome.

Not sure what you mean by 'hub' in this context (network router?) and what the Sparkfun keypad has to do with it.
[Thinking time...]
OK, do you want to wire the keypad using the UTP cables then unplug them from wherever they are currently connected so you can plug them into an Arduino Nano?
If so (please confirm for me and others) then crosstalk will probably not be an issue as we're talking high enough voltages here (5v or thereabouts). Best way is to try it out using a simple example sketch and see what happens. If you need to boost the signal (I'd be surprised but stranger things happen at sea) then you will find out sooner than later.
What is it exactly you're hoping to do here, it would greatly help if you could clarify 
If the keyboard is used to unlock the door, you need another two wires for a solenoid lock and another one for a beeper for key presses and passkey wrong/correct audible feedback. That means you-re short on wires on a single utp cable
Maybe think about using an IR keypad.
