When my car stopped starting, I took it to 2 mechanics, one friend and the other a shop. None of them could get it to start, and the shop told me there was a problem with my security system. It's a factory unit, and not aftermarket. They told me that when I crank the car, the "securtiy" light should turn off, but now it just stays on while the car is cranking, and now it won't start. Any suggestions on what I should do? Thanks.

 

Sounds like the immobilizer has kicked in.
Your going to have to get the car to Nissan and have the system reprogrammed to your keys.

 

Thanks, NJMAXSELTD, how and why did this happen? The day I drove it was in the morning, and it was fine, but when I went to start it around 3 in the afternoon it just would not start.

 

you got another key, try that one.

 

I do, and the other key does not work as well.

 

what about "rebooting"? disconnect batt, wait then reconnect...

 

Tried that... still does not work.

 

try unglugging the box in the back by the antenna inside the trunk behind the carpet thing. unplug it and replug it and see what happens.
when my remote wasnt working i did dat and it works fine for me now! worth a try.

 

Well, I just towed the car to the dealership and they are going to charge me $85 for just looking at it. Man, what a rip off.

 

You ain't seen ripoff yet. Wait till they call you.

 

yo dont bother.... get a new alarm for 150 installed it will by pass the original... worked for me!!!!!

 

You can't bypass the immobilizer system on a 99. The ignition key is chipped and programmed into the ECU. The car will not start unless it recognizes the correct key code.

 

True, paid the stealership $85 to reprogram 2 keys, at least my car works now.

 

Do you guys know if the 98 gle key is chipped too? cuz my car aint starting either and I had a key made from the dealer
