My 2010 QX 56 just did something weird. It is parked, locked, and is unattended. After sitting in my driveway for about two hours, all of the windows suddenly lowered on their own. All four went down in sync. The car was not running and was locked. The car was parked in my driveway in front of my surveillance camera which captured the event.

SOURCE: i have an 2005 infinity qx 56 that all of a sudden

if it is only clicking it is either your battery or starter. It would still turn over if it was fuel pump, it just wouldn't start.

SOURCE: The ignition in my Inifitini

Wiggle the steering wheel while trying to turn the key.Try shaking the steering wheel while using the manual key. The steering wheel ultimately unlocks and the car started.Try hitting the steer wheel hard,with a rubber mallet on its center.Take care nothing gets cracked. ----------- INFINItI Intelligent Key tM This system allows you to lock and unlock your vehicle, open the power lift gate, and start and stop the engine without having to remove the Intelligent Key from your pocket or bag. Two Intelligent Keys are provided with your INFINITI vehicle.

P (Park is recommended). 3 Push in the ignition switch and crank the engine with your foot off the accelerator pedal by turning the ignition switch to the START position. Release the ignition switch when the engine has started. To Stop the Engine: 1 Put the transmission in P (PARK). 2 Turn it to the LOCK (OFF) position. The ignition lock is designed so that the ignition switch cannot be turned to LOCK (OFF) unless the transmission is in P (PARK). --------------- Also its possible that key fob needs reprogramming or your present key is not getting detected.if you have any other key,then try with that spare key.
