Emergency 2015 Infiniti QX50 key fob made from scratch by EZ Car Keyz Simi Valley CA
🔧 PRO TIP
The 2015 QX50 runs a 315 MHz intelligent key system. The fob takes a CR2032, and that battery matters more than people think on these. A weak cell doesn't just shorten range, it can make the push-button start act confused even when the fob is right on the center console. The car may see the key intermittently and throw a key-not-detected warning mid-session. Swap the CR2032 first, make sure the contact clips are seated flat, not just in. If range and door handle unlock come back but start still hiccups, you're looking at a registration or antenna issue, not a dead fob. Also worth knowing: all-keys-lost on the QX50 is a real job with real steps. There's no onboard self-program sequence for this system. You need diagnostic equipment to talk to the immobilizer and generate new key data. Don't let someone with a basic OBD reader talk you into it.

2015 Infiniti QX50 Smart Key Replacement - Fast, Affordable & Professional

A guy in the Simi Hills area called me on a weekday evening. He was home, which was good, but his QX50 was sitting in the driveway completely dead to him. Not dead as in battery, dead as in he'd washed his jacket and found the remains of his only fob at the bottom of the drum. The water hadn't just killed the battery. The board was corroded and the case had cracked at the seam.

He'd already called the Infiniti dealer. They told him they could order a key, but he'd need to bring the car in, they needed the car present, and the earliest they could do it was three days out. He didn't have another key to bring the car in. He was stuck on that logic loop when he found me.

I asked him to grab the VIN off the windshield before I left, so I could confirm the right fob and have everything staged in the van. He found it in about thirty seconds once I told him exactly where to look, bottom left of the windshield, driver's side. That's the piece of information that lets me show up ready instead of guessing.

When I got there, the driveway was lit by the garage light and he had his registration out already, which I appreciated. I verified ownership, pulled the prepped fob, and got to work. The QX50 intelligent key system requires going through the OBD port to register a new key to the immobilizer. I ran the process, walked all the door handles for touch unlock, confirmed push-button start, and checked every button on the fob under the garage light before I packed up.

The whole thing took about forty minutes. He had a working key that night. The dealer's three-day window never came into it.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

Infiniti QX50 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace a lost key for the 2015 Infiniti QX50?
Call a mobile locksmith first. Dealers on Infiniti forums consistently quote owners several hundred dollars for a single intelligent key replacement, and that's before towing if you're already stranded. A mobile locksmith comes to you, programs on site, and the total is a fraction of what the dealer charges. No tow, no waiting on a VIN-ordered part to arrive, no separate line items for the fob, the cut key insert, and the programming labor. If you're in Simi Valley or the Simi Hills area, that's exactly what I do. Call before you call the dealer.
How much harder is all-keys-lost on the QX50 compared to adding a spare?
Do aftermarket fobs actually work on the 2015 QX50, or should I stick with OEM?
My QX50's door handle touch unlock stopped working on one side. Is the fob failing?
The push-button start on my QX50 randomly says it can't detect the key, but the fob works fine other times. What's going on?
