Emergency 2015 Infiniti QX50 key fob made from scratch by EZ Car Keyz La Mesa CA
🔧 PRO TIP
The 2015 QX50 smart key runs on the same underlying security architecture as several Nissan models from that era, which matters practically: a qualified locksmith with the right diagnostic platform can service this fob the same way they'd handle the Nissan equivalent. The fob takes a CR2032, and a weak one can mimic a much bigger problem before it fully dies. You get reduced range, the door handles stop responding to touch, and eventually a key-not-detected warning even when the fob is right in your hand. Swap the battery first, seat it clean against both contacts, and retest all three buttons before assuming the fob itself has failed. Also worth knowing: if you had a dead battery for a while, the fob sometimes needs a re-sync before it talks to the car properly again. That is a quick step with the right equipment, not a full reprogramming job.

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

Out in Casa de Oro, a guy called me from a gravel overflow lot off the main stretch. He had bought his 2015 Infiniti QX50 used about a year before, and the previous owner had handed him exactly one fob. That was the whole set. He had been meaning to get a spare made and never got around to it. Then one morning the single fob went somewhere it was not coming back from.

He figured the car was stuck until he could arrange a tow to the dealer and wait however many days it took them to sort it out. I told him I could be in Casa de Oro that afternoon and handle it on site.

When I got there, the QX50 was just sitting in the sun with no way in. I used a mechanical entry method to open the door without touching the lock hardware, then got to work decoding the lock cylinder so I could cut a matching emergency blade. That blade is the backup inside the smart fob itself, and it has to be right.

From there I connected through the OBD port and ran the all-keys-lost procedure. That sequence clears every fob the immobilizer had on record and registers the new key as the only one. It takes a few minutes because there is a timed portion built into the process that you cannot rush. When it finished, he pressed the start button, the engine came up, and he just stood there for a second like he was waiting for something to go wrong.

I cut him a second fob while I was there. He had already lived through what having only one gets you.

Dealer route would have meant a tow, a service write-up, parts on order, and probably a multi-day wait. He paid a fraction of that, standing in the same parking lot where the car had been sitting all morning.

Infiniti QX50 Mobile Service FAQ

Real costs, no dealer surprises

How much does a 2015 Infiniti QX50 key replacement cost?
Call us for the exact number, but it will be way less than the dealer. Infiniti dealers routinely break the job into separate line items: the fob itself, the emergency blade cut, programming labor, and sometimes a diagnostic fee on top of that. By the time you add those up, the total can get uncomfortable fast. With EZ Car Keyz, one price covers the fob, the blade cut to your vehicle, programming, and the mobile service call to wherever you are in La Mesa or Casa de Oro. What we quote on the phone is what you pay.
Is going with a locksmith actually cheaper than the Infiniti dealer for this?
Does your price include cutting and programming, or are those extra?
My 2015 QX50 fob battery died completely and now the car will not recognize it even with a new CR2032 in there. Did the fob lose its programming?
I found a replacement fob for my 2015 QX50 online. Can I program it myself or do I need someone with equipment?
