My car is old

, as are my keys. the edges are beginning to grind down, and it makes me stand in front of my door for a good 30 seconds to a minute trying to get it to unlock. (ignition turns prefectly though)
Basically, the question is, what can I do to get new keys? I heard that since my S13 ('89) is too old, Nissan can't make me a new one. So wtf am I to do?
