A smart key is the type of key your 2016 Infiniti Q50 uses. It contains a programmed chip that communicates with your vehicle NATS immobilizer and BCM to verify it is an authorized key before the engine will start. It also has 5 buttons for remote lock, unlock, and other functions depending on your trim level. Without proper programming, even a perfectly cut key will not start your Infiniti.

Q: Why does the dealer take so long on Infiniti keys?

Because Infiniti intelligent keys are VIN-specific and often need to be ordered from a central warehouse. The dealer cannot just grab a blank off the shelf. They order the key, wait for it to arrive pre-coded to your VIN, then schedule shop time for programming through their diagnostic system. Infiniti dealers also charge separately for the fob, cutting, and programming labor. One FX owner said the dealer wanted 150 just for diagnostics before any work started. We cut all of that out and do the job at your vehicle in one visit.

Q: What is the FCC ID for the 2016 Infiniti Q50 key?

The FCC ID is KR5S180144014, KR5S180144203. This is the identifier printed on the back of your key fob that tells us exactly which key your vehicle requires. It ensures we match the correct blank, chip frequency, and remote protocol so the key programs correctly on the first attempt. Having this number ready when you call speeds up the process and confirms we are bringing the right key to your location.

Q: Is same-day service available for all-keys-lost?

Yes, for most Infiniti models. We carry common Infiniti key blanks on our truck and have the BCM programming tools to handle most all-keys-lost situations the same day you call. The full AKL process including security access, PIN extraction, key generation, cutting, and BCM registration typically takes 45 to 90 minutes on site. Infiniti dealers cannot do same-day AKL because the key must be ordered by VIN and shipped, which takes days. We bring everything to your vehicle and get it done in one visit.

2016 Infiniti Q50 Smart key Replacement - Fast, Affordable & Professional

Sunday morning outside the yoga studio in Thousand Oaks. A studio owner with a 2016 Infiniti Q50 came out after teaching her first class and her smart key wouldn't unlock the car. Dead buttons, no push-to-start response, nothing. The Infiniti dealer was closed until Monday and her next class started in two hours.

She needed it fixed now. The only number that answered on a Sunday morning was mine.

I got to the studio lot in about 40 minutes. I tested her fob first and the CR2032 battery was dead, plus the transponder was corrupted signal that a simple battery swap alone wouldn't clear. I used my VVDI Key Tool to generate a fresh transponder chip and build a new smart key matched to her vehicle's IMMO module. Her new fob, FCC ID KR5S180144014, was a 5-button smart key. I programmed it through OBD, tested lock, unlock, trunk, and start, then confirmed range from across the lot.

She made it home and back in time for her second class. Total was 346. Dealer would have been 625 on Monday. Weekends are the same rate for me.

“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”

Infiniti Q50 Same-Day Key Replacement FAQ

Money questions, straight answers

How long does the Infiniti dealer take for key replacement?▼

Longer than you would think. Infiniti dealers often need to order your intelligent key by VIN, which can take several business days. Owners in key-order discussions report being told 2 to 3 days but then having to chase the service manager when the key does not show up. On the Nissan side of the same platform, one owner waited 3.5 weeks just for a dealer appointment. Once the key arrives, expect at least an hour at the dealer for programming and testing. Add it all up and you can easily be without your Infiniti for a week or more.
