How do you turn off the immobiliser on a 2000 Nissan Quest?

To turn off the immobiliser on a 2000 Nissan Quest, you typically need to use the key or key fob that is programmed to the vehicle. Insert the key into the ignition and turn it to the "On" position without starting the engine. If the immobiliser light on the dashboard turns off, the system is disarmed. If you don't have the correct key, you may need to contact a dealership or a locksmith for assistance.
