About Your 2026 Infiniti Q40
Infiniti is a Japan brand owned by Nissan Motor / Renault-Nissan-Mitsubishi Alliance. Their key system uses Nissan NATS with Transponder, Intelligent Key. Infiniti shares Nissan's NATS immobilizer platform but with premium features. Programming requires security access through the vehicle's BCM.
The 2026 Infiniti Q40 is a sedan. Most Q40 keys of this generation use the Hitag AES / PCF7952 transponder chip, remotes under FCC ID KR5TXN7 / S180144304, the NSN14 key blade — exactly the hardware we cut and program on-site. Key blanks for the Q40 are stocked on the truck, so a typical spare-key visit anywhere in Duval County wraps up the same day, without a tow.
Your 2026 Infiniti Q40 is a modern-era vehicle and uses the latest revision of Infiniti's key security platform. Programming requires advanced equipment but is fully aftermarket-supported on-site — no dealer trip needed in most cases.
Immobilizer (NATS 6+): Nissan's NATS 6+ is the oldest modern immobilizer still in active use — it's been on Nissans since 1999 and is one of the easiest platforms to program.
