Just tried this on my 2004 INFINITI Q—anyone else have success?

Following this for my 2004 INFINITI Q. Please update if it works!

Why is finding a key code on a 2004 INFINITI Q this hard?!

Hoping someone can confirm this works for a newer 2004 INFINITI Q.

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Security Systems
Not recommended. Bypassing requires specialized knowledge and may violate anti-theft laws. Proper solutions: 1) Get correctly programmed keys 2) Replace faulty immobilizer components 3) Have dealer reset the system if keys are lost.
Security Systems
This means your car's immobilizer system can't read the key's transponder. Causes: dead key battery, damaged transponder chip, faulty car antenna ring around ignition, or system needs resetting. Try replacing the battery first.
Key Programming
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
Lost Keys
Locksmiths or dealers can: 1) Decode your door or ignition lock to determine key cuts 2) Access your car's key code through manufacturer databases (with proof of ownership) 3) Program new transponder keys using diagnostic equipment.
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Lost Keys
Costs vary widely: Basic keys: $50-$150, Transponder keys: $150-$300, Smart keys/fobs: $200-$800, Dealership replacements typically cost 20-50% more than locksmiths. Emergency/lockout service adds $50-$150.
Key Tip: Newer cars often require dealer programming for first key replacement
Key Fact: Some luxury car keys can cost $800+ to replace at dealerships
