Bring both keys to the dealer to have them reprogrammed to your cars security system.

This exact thing happened to me about a month ago, your immobilizer is messed up and you have to go to the Nissan dealership to get the keys reprogrammed. It costs about $85 to reprogram both keys. It messed up because someone tried to put a different key in the ignition or you somehow messed up the chip inside the keys. (99 Maximas have computer chips inside the keys)

ok wait so if the car started at first and died right away a couple of times and then didn't start at all its the immobilizer? cuz it cranks fine but for some reason won't start... wat else could be causing that?

It is the immobolizer, for sure. That happened to me also, I started the car and it started but died after like 3 seconds. Then it just cranks whenever I try to start it, took it to the dealship, paid $85 to get it fixed, now I am happy with my working car. You should try that and not waste anymore time trying to figure out what's wrong.

There is a lot of mis-information about the immobilizer system on the Max.
The keys are not programmed, they are not able to lose their program because they never had it. The chip has been known to fall out of the key and be lost, but that is another matter entirely.
The CAR is programmed to recognize the KEYS used in the programming process. Sure, the system can malfunction like anything else. But the key does not become unprogrammed, deprogrammed or anything like that.

It is possible to break anything, including a key with a chip inside.
I once threw my remote at the wall, and it no longer opens or closes the locks on my car. But the other remote that I have still works. The car did not deprogram.
But I'm telling you, a car with an immobilizer system is programmed to accept the KEY, not the other way around. And yes, the car can accept up to 5 different keys as long as they are all inserted into the ignition switch during the programming process.
