03 Altima factory security

So a couple weeks ago I posted a question regaurding a fuel pump for my altima,turns out it was 8 codes {from cruise control switch to vehicle interrupter/immobilization codes} majority of which were the latter. My question is"has anybody had or heard of issue like this"? I dont have a factory key,its an aftermarket chipped key. i dont have a key fob either. I have new ones but cant get an answer on how to have them progtammed without having factory programmed key. Thanks

If you have only 1 working key, you’ll have to take the car to the dealer to program any additional keys.

Or try a locksmith. You’d be surprised what a locksmith can do for a lot less cash than a dealer.

It’s worth a call at least.
