🔧 PRO TIP
The 2004 G35 intelligent key is older than most people expect when they think "smart key." This was early adoption for Infiniti, and the fob hardware reflects it. The factory fob takes a CR2032, and that part is easy. What trips people up is that the battery contacts inside the shell are thin and prone to slight corrosion, especially in a car that sits in a garage. A brand-new CR2032 can read nearly dead if the contacts aren't clean. Before anyone concludes the fob is fried, pop it open, wipe the contact points with a dry cloth, seat the battery firmly, and retest. Also worth knowing: on these early intelligent key setups, the door handle request sensors can get flaky with age. If the car stops detecting the fob at the door handle but still starts fine, the key itself is usually not the problem.

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

I got a call from a woman parked in a garage near the Santa Susana Knolls side of Simi Valley. Weekday evening, she'd stepped away from her 2004 G35 for maybe thirty seconds to return a cart. Came back and the fob was dead. Baby strapped in. Doors locked. She could see her kid through the window.

I told her I was on my way and walked her through using the mechanical insert key to get the door open while I drove over. She'd forgotten the insert key was even in there. Door was open before I pulled in.

Once the baby was out and settled in the stroller, I looked at the fob. Fresh battery a month prior, she said. I checked the contacts first. One of them had a slight bend and wasn't making full contact with the cell. Straightened it, reseated the CR2032, tested it. Nothing. The fob circuit itself had given up.

I built a replacement from stock I carry, programmed it through the OBD port, cut the emergency blade to match the lock, and walked every function: lock, unlock, the remaining buttons, ignition start. The whole thing happened on the garage level while the kid slept in the stroller.

She paid a fraction of what the dealer would have quoted, and she drove home that night. Some jobs are just jobs. That one I remember.

Infiniti G35 Mobile Service FAQ

Real costs, no dealer surprises

Do you use OEM or aftermarket keys on the 2004 G35?
We carry professional-grade replacements built to OEM spec, meaning the transponder, the blade cut tolerances, and the shell quality all match what the car expects. The factory fob on the 2004 G35 has a known shell weakness around the key ring attachment point and the emergency blade housing. Cheap online clones copy the shape but often shortcut the internal electronics, and G35 owners on forums have documented repeated start failures and lost fob recognition with those. We test every key we bring on actual Infiniti vehicles before we put it in our stock. If it doesn't behave exactly like a factory unit, we don't use it.
How long will a replacement key hold up on a 2004 G35?
What if the new key stops working a few weeks after you program it?
I found a used 2004 G35 fob online with the right factory ID. Can you just program that one instead of buying a new key?
The G35 starts fine but the door handles stopped detecting the fob. Is the key failing?
