🔧 PRO TIP
The 2016 Q50 runs Nissan's NATS6 immobilizer through the BCM (body control module, part 284B1 on these). The KR5S180144014 fob uses a Hitag AES crypto chip, not the older Hitag2, so generic aftermarket fobs with the wrong transponder type won't pair no matter what tool you throw at them. A dying CR2032 will trigger "I-Key System Error" or "Key ID Incorrect" on the dash before total failure. If you see either message, swap the battery first. If the message stays, the issue is deeper than voltage.

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

Sunday morning in Thousand Oaks, over in the Casa Conejo neighborhood. A woman came out of a yoga studio after teaching her first class and her 2016 Q50 was completely dead to the fob. No button response, no proximity unlock on the door handles, no push-button start. Just the little red security light blinking on the dash when she looked through the glass.

Infiniti dealer was closed until Monday. Her next class started in two hours.

I got to the lot in about 40 minutes. Popped her fob open on the hood and the CR2032 was toast, totally flat. But swapping in a fresh cell only got half the system back. Doors locked and unlocked, but the dash still threw "Key ID Incorrect" when she hit the start button. The Hitag AES transponder profile had dropped out of sync with her BCM.

That's where the diagnostic tool earns its keep. I connected through the OBD port under the dash, pulled up the NATS6 module, cleared the corrupted key data, and re-registered her KR5S180144014 fob from scratch. Five-button unit: lock, unlock, trunk, remote start, panic. Tested every function, then walked to the far end of the lot and confirmed range.

She drove home, came back, and made her second class with time to spare. The whole thing took less than an hour on site, for a fraction of what the dealer would have quoted on Monday.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

Infiniti Q50 Mobile Service FAQ

Real costs, no dealer surprises

How long does the Infiniti dealer take for a Q50 smart key replacement?
Longer than most people expect. Infiniti dealers typically order the intelligent key by VIN from a central warehouse, and owners on the Infiniti Q50 forums report wait times of two to five business days just for the part to arrive. One poster on InfinitiQ50.org said he was told "two to three days" and ended up chasing his service advisor for over a week. Once the fob shows up, plan on another hour or so of shop time for programming through the Nissan CONSULT III Plus system. Add scheduling delays and you can easily go a full week without your car. I carry compatible smart key blanks on my van and do the whole job in one visit.
What does "smart key" actually mean on a 2016 Infiniti Q50?
Why can't the dealer just grab a blank key off the shelf for my Q50?
My Q50 dash says "Key ID Incorrect" but the fob buttons still work. What is going on?
Can I buy a Q50 smart key fob online and program it myself?
