do i just need to reprogram key?

Question

on my Nissan maxima 2002, if the wrong key was used several times to try to start car and now it wont start with previous working key, do I just reprogram the key I was using before the bad keys were used or do I need to replace or reprogram the unit

Answer 1

You would need to initialize the system try this put the registered key in the ignition , turn the ignition on but do not start the engine, with the key in the on position wait 5 seconds then turn off repeat this step in a total of 3 cycles and try to start the vehicle
