Nissan Rogue Sport Key Tech, Year by Year
J11 Facelift, Intelligent Key
A smart key with three buttons (lock, unlock, panic) and a hidden mechanical blade tucked inside the fob. Your Rogue Sport uses the NATS immobilizer system with a Nissan transponder chip, which means the key communicates wirelessly with your car and requires server authentication to program. The FCC ID is KR5TXN1, and the fob runs on a CR2032 battery. Base S trims may have a traditional transponder key instead of the full Intelligent Key setup.
J11 Final Facelift, Same Platform
A smart key identical in function to the 2019-2020 models, still running the KR5TXN1 fob with NATS immobilizer and CR2032 battery. Nissan kept the security architecture consistent across this final run of the Rogue Sport. The mechanical emergency blade is still hidden in the back of the fob, and programming still requires Nissan server authentication through diagnostic equipment.
Identify the Key on Your Rogue Sport
This the rectangular black fob you carry in your pocket. It talks to your car wirelessly so you never have to take it out to unlock or start. There's a small metal key hidden inside for emergencies.
Same smart key design as the earlier years. Three buttons, CR2032 battery, and a hidden mechanical blade you can slide out if the fob battery dies. Push button start on SV and SL trims.
The Real Cost of a Rogue Sport Key
Price includes the key fob, cutting the emergency blade, programming to your vehicle, and testing; no hidden fees.

Nissan Rogue Sport Key Issues We Knock Out in San Diego
Proximity Cell Dying, Push-Start Goes Silent
Rogue Sport ignores the handle, push-start refuses. CR2032 in the fob lasts roughly two years on daily-driver duty; when it fades every wireless function drops at once. Swap yourself; symptoms hang around? Dial (619) 876-1271 for a curbside replacement.
Key Registration Required for Telematics
Nissan's telematics module needs a TCU update or replacement. When it does, every Intelligent Key has to be re-registered through the dealer server. Had three, only bring two? The third is dead. We knock out re-registration in Chula Vista or Carlsbad.
Proximity Detection Issues
We check fob battery first; nine times out of ten weak Rogue Sport proximity traces to a dying CR2032. If fine, usually RF interference from other electronics. Carry the fob alone. Still no? The antenna may be damaged; we test on-site in Encinitas.
Can You Program the Rogue Sport Key Yourself in San Diego?
No DIY programming exists for this generation. The NATS immobilizer requires diagnostic equipment connected to the OBD port and Nissan server authentication. There's no key-in-ignition trick or button sequence that works.
Same story here. Nissan's security system erases all previous keys during programming, so it requires professional diagnostic tools and server access. You can't add a key at home.

San Diego Trivia Worth Knowing
Quiet detail most San Diego Rogue Sport owners miss: Nissan's Intelligent Key supports up to four registered fobs per vehicle, and each fob has a tiny transmit indicator LED that blinks when it broadcasts. If three of you share the Rogue Sport between Encinitas roommates, you can literally watch which fob the car is responding to. Useful when something acts up and you cannot tell which fob is the problem child.
