🚗 Smart Key Programming Service for Infiniti FX35 & FX45 (2003–2004)

Professional Key Replacement & Programming – Staten Island, NY

We provide expert proximity smart key programming for the first-generation Infiniti FX crossover. This listing specifically covers the early 433 MHz NHVWBU612 system. As one of the first "Intelligent Key" systems ever released, it requires specialized legacy diagnostic tools to sync the proximity sensors with the vehicle's early security module. Our service restores full Push Button Start and keyless entry functionality.
