2004 Infiniti G35
Quick-Turn Key Replacement in Ventura County

Q: How long will the replacement key last?

With periodic battery changes and normal use, a properly programmed Infiniti intelligent key should last years. The transponder chip and internal electronics are durable. The most common physical failure on Infiniti fobs is the plastic housing cracking around the key ring bridge and the emergency blade area. This is the same shared Nissan/Infiniti shell design dating back to 2006. If the shell wears out, the internal electronics can usually be transferred to a new housing without reprogramming as long as the transponder chip is intact.

Q: What if the new key stops working after a few weeks?

Call us and we will come back. Every key we make is covered by our warranty. If it stops starting the car, loses remote function, or develops any issue under normal use, we fix or replace it. G37 owners on Reddit describe keys that were not programmed correctly and stopped being recognized, requiring a return trip to the dealer. Locksmiths warn that certain Nissan/Infiniti BCMs can brick during programming if done with wrong tools. We test every function before we leave and stand behind our work.

Q: How many buttons does the 2004 Infiniti G35 key have?

Your 2004 Infiniti G35 key has 4 buttons. The button count helps identify exactly which fob your vehicle uses, since Infiniti uses different key designs across intelligent key, proximity, and older non-proximity variants. When you call us, having this detail along with your year, make, and model helps us confirm the right key before we even head out so there are no surprises when we arrive.

Q: Can I trust an aftermarket Infiniti key to be reliable?

It depends on the source. Professional-grade aftermarket Infiniti intelligent keys from reputable locksmith suppliers work reliably and are what most qualified locksmiths use. But ultra-cheap clones from Amazon and eBay are where problems spike: cracked cases, short battery life, intermittent operation, and buttons that die within months. Because Infiniti is a luxury brand, some owners are extra cautious about aftermarket, and for good reason on the cheap end. We use OEM spec keys specifically to avoid those reliability risks on your Infiniti.

2004 Infiniti G35 Smart key Replacement - Fast, Affordable & Professional

A mom with an infant in the car seat was at the shopping center garage in Simi Valley on a weekday evening when her 2004 Infiniti G35 key fob stopped working. The car was locked, the baby was strapped in, and the remote wouldn't respond. She could see her child through the window. She'd been gone for thirty seconds to return a cart.

The dealer was closed. A tow wasn't what she needed. She needed the door open and the car running. She found EZ Car Keyz and called.

I got to the garage as fast as I could. I got the door open first priority and she got the baby out immediately. Then I diagnosed the fob. Failed circuit board, not just a dead battery. I used my VVDI2 to read the transponder data from the dead fob and transfer it to a new unit, which meant I could skip a full all-keys-lost reprogram. Her replacement fob, FCC ID KBRTN001, was a 4-button smart key that I built, cut the emergency blade, and programmed through OBD right there. The baby slept through the entire thing in the stroller next to us.

She drove home that evening. Total was 185. Some calls aren't about price or convenience. That one stays with me.

How on-site key replacement works

Do you use OEM or aftermarket keys on Infiniti vehicles?▼

We use OEM spec keys that match the factory part number, chip frequency, and blade profile for your specific Infiniti. Professional-grade aftermarket intelligent keys designed for locksmith use work reliably on Infiniti models, but cheap Amazon and eBay clones are a different story. Locksmiths report that ultra-cheap keys for Nissan and Infiniti platforms show up with incomplete electronics and intermittent start issues. We carry keys we have tested and verified on Infiniti vehicles so you get a key that works and lasts.
