So its really simple... all you have to do is buy or craft a blank a blank key.. they sell blank keys in the buildimg over the npc where you bought your house.
Then dclick the blank key and target the key you wish to make a copy. sometimes you may fail.. but no big deal.. You wont lose the key if it fails hehe
dont forget to put it in a keyring since keys are not newbied!

Ok thanks a lot Raziel! eheh also thanks for the tip about the key ring
