are there any good key program tool for nissan
 

My car keys only one left, I heard that if both the two keys lost,it will be in trouble. So I want to go to match the keys. as far as know ，to cut a key is not cheap.it will be more than 100 dollars. So I want to do it by myself. Have some friends used any relatively good tools?Someone recommended the T300 key programmer ? nyone know about it?Any information will be gratefully received.Thanks.
