You're sitting in your Infiniti Q50 in a parking garage under Rockefeller Center, and the dashboard reads "Key ID Incorrect." You've tried both fobs. Same result. Infiniti represents Nissan's luxury division, and while the mechanical underpinnings share DNA with Nissan, the key programming is a different beast entirely. The Infiniti Intelligent Key system uses encrypted communication that requires specialized tools to program. Our technicians have deep experience with Infiniti's security architecture, from the older NATS (Nissan Anti-Theft System) to the latest CAN-BUS intelligent key systems in the QX80 and QX60.

Infiniti Key Systems Explained

Infiniti uses Nissan's Intelligent Key system with luxury-specific enhancements. The system operates on a 433MHz frequency for remote functions and uses LF (Low Frequency) antennas inside the vehicle for passive entry and push-button start. Older Infinitis (G35, FX35) used the NATS immobilizer with a transponder chip in the key. Modern Infinitis — Q50, Q60, QX50, QX60, QX80 — use the latest Intelligent Key system with proximity fobs. The key blanks are specific to Infiniti and differ from standard Nissan keys. We carry OEM-quality blanks for all Infiniti generations and have the programming tools to handle the encrypted Intelligent Key protocol.

Common Infiniti Key Problems

Intelligent Key Battery Drain

Infiniti fobs are known for draining batteries, especially on the Q50 and QX60. The fob stops working for proximity entry but the buttons may still work.

Key ID Incorrect Error

The vehicle doesn't recognize the fob. This can happen after a battery change or if the fob has been de-synchronized. Requires reprogramming.

Push-Button Start Failure

The engine won't start even though the fob is detected. Often a brake pedal position sensor issue or a faulty start button.

Door Handle Request Switch Failure

The button on the door handle stops working for locking/unlocking. Common on QX60 and QX80 models.
