Hello! This is my first post and I'm in need of some help!

My 2004 350z immobilizer remains on when trying the ignition.
My key FOB buttons unlock the door but the immobilizer light stays solid.
I have tried holding it in the ignition position for 5 secs and in the off for 10 secs 2 or 3 times but the light is still on!!
Any help would be greatly appreciated! Thanks.

 

Something is wrong with the immobilizer, causing it to not start. Not easy to diagnose or fix... Best option IMO is to just bypass the immobilizer with an Uprev reflash which will also make the car way more fun to drive
