INFINITI FX35 ignition issue with no power to key fob or electrical systems, possibly due to anti-theft system or ignition failure on INFINITI FX35

Some INFINITI FX35 owners report experiencing ignition issues characterized by a lack of power to the key fob and electrical systems. Commonly, these problems stem from a communication error between the key fob and the vehicle's receiver, resulting in the key fob not being recognized or the ignition failing to turn with the physical key. Additionally, interference with the anti-theft system can disrupt the signals from the Intelligent Key, leading to detection failures and error messages on the instrument cluster. Owners may also encounter difficulties due to issues with the ignition switch or a binding steering column, which can prevent the key from turning. Furthermore, insufficient power from the alternator may contribute to starting problems, particularly if low-powered accessories are noted while driving. It is advisable for owners to troubleshoot these areas to identify and resolve the underlying causes of their ignition issues.
