About Your 2026 Infiniti EX35
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 EX35 is a crossover SUV. Most EX35 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. Infiniti programming is fully aftermarket-supported, so one mobile visit covers key cutting, chip programming, and remote pairing in a single stop.
