🔧 PRO TIP
The 2018 Q70 uses the same Infiniti Intelligent Key platform that carried through the final years of this sedan's run. One thing owners miss: the fob has a CR2032 inside, and when it gets low, the symptoms don't always look like a battery problem. You might get intermittent detection, reduced range on one side of the car, or the car recognizing the key in the cabin but not at the door handle. The fob also has a hidden emergency blade tucked inside the bottom. A lot of Q70 owners don't know it's there until they're locked out and need it. If you're getting a key-not-detected warning on and off, swap the CR2032 first and seat it firm before assuming the fob needs to be reprogrammed. Nine times out of ten, that's the whole story.

2018 Infiniti Q70 Smart Key Replacement - Fast, Affordable & Professional

I was parked near Live Oak Park Area on a Tuesday when I got the call. The owner had a 2018 Infiniti Q70 and had been dealing with an on-and-off warning for about two weeks. Key wasn't being detected consistently. Some mornings it worked fine. Some mornings he had to sit there and wait a beat before the car would respond.

He'd already done some reading. He knew his fob ran a CR2032. He'd swapped it himself, which was the right first move. The new battery helped for about a week, then the same thing came back.

When I got there, I opened the fob and looked at the battery contacts. The swap had been done cleanly, but one of the contact clips had a slight outward bow to it, not making full contact with the cell. That kind of thing is easy to miss. A quick adjustment, reseated the battery, and I retested at all four door positions and at the push-button.

Better, but not fully clean. The detection at the driver door handle was still a half-second slow compared to the others. That told me the fob was borderline and the contact fix alone wasn't going to hold long-term.

I built a fresh replacement on site, programmed it through the OBD port, and confirmed the original fob was still enrolled as a backup so he wasn't left with just one key. Ran every button, three start cycles, and walked the perimeter checking all detection zones.

He mentioned he'd called the dealer first. They'd quoted him a wait for an appointment and a parts order. By the time I was packing up, he was already late for lunch, which he said was a better problem to have.

Infiniti Q70 Mobile Service FAQ

Real costs, no dealer surprises

My fob shell is cracking near the key ring. Can you replace just the shell without reprogramming?
Yes, and it's one of the more common fixes on these fobs. The plastic housing on the Q70's Intelligent Key tends to develop stress cracks around the key ring bridge and near the emergency blade release, especially on fobs that have been on a heavy keychain for years. The fix is a shell swap: transfer your original circuit board into a new housing, reinstall the emergency blade, and you're done. No reprogramming needed because the electronics never leave the equation. The paired data stays on the original board. As long as nothing gets damaged in the transfer, the car won't know anything changed.
What exactly is a smart key and why can't I just cut a new one at a hardware store?
My Q70 is showing a key-not-detected warning. Where do I start?
I have a spare key that I've never used. Do I need to do anything to keep it active?
Can I program a second Q70 smart key myself at home?
