How do you program a key-less remote 2004 Nissan Maxima?

Answer 1

1. close & lock all door using driver's side power lock switch 2. place key in & (fully) out of ignition 6 times within 10 seconds

(the hazard lights will flash 2x) 3. turn the key to the acc position 4. unlock and relock the doors with the switch on the driver's door 5. press the lock button on the remote (the hazard lights should flash again) [NOTE: This part is less certain but if there are any other remotes (including old), unlock doors (and re-lock?) within 5 seconds, then press lock button on the next remote; repeat for remaining remotes] 6. remove the key, unlock door, open and close door, and try remote
