lost keys & don't have the key code- 96 j30

Well I don't have a spare key or I wouldn't be worrying about this code.. It is my stepdads car he gave it to me to use while I got on my feet and only gave me the one key & I lost my whole key ring shortly after. I was unaware that he didn't have a spare at his house, I haven't been great about hanging onto keys so usually leave my spare with one of my parents so someone always has an extra copy for me. Wasn't until after I lost my key ring that I found out he didn't have a spare or I would have had a copy made in the first place.

good luck with it.
