How to start the vehicle if INFINITI Intelligent Key is not working because of low-battery?
Intelligent Key fob, like any other remote, contains a small battery. If you find that it is not working unless you're less than two feet away from your vehicle; the battery should be replaced.
On the other hand, and even if the Intelligent Key battery is almost discharged, the engine can still be started, in two different ways depending on the vehicle:
1- For Q60 Convertible, Q60 Coupe, and QX50; insert the Intelligent Key fob into the key port on the lower left dash panel, and then start the engine.
2- For Q50, QX60, and QX80; touch the ignition (Start/Stop) button with the Intelligent Key fob. You’ll hear a chime. Within 10 seconds, push the ignition button while depressing the brake pedal to start the engine.
