TextHow the 370Z Key System Evolved
Z34 Early
Your early Z34 uses a 3-button smart key with an ID47 transponder chip and push-button start from day one. The NATS immobilizer talks to the chip inside your fob every time you press that start button. Programming is done through OBD-II or on-board procedures, which means we handle it on-site without any dealer involvement.
Z34 Mid
Your mid-generation Z34, including the NISMO variant, keeps the same ID47 chip and 3-button smart key as the earlier cars. Nissan did not change the key system here, so the NATS immobilizer and programming method stayed consistent. Same OBD-II and on-board programming, same CR2032 battery, same high-security blade.
Z34 Late
Your late Z34 still runs the ID47 chip and NATS immobilizer, but Nissan may have added server authentication to the programming process on some of these. That means the job can take a bit longer, but we have the tools and access to handle it. Still a 3-button smart key with push-button start and the same CR2032 battery.
Identify the Key on Your 370Z
A proximity smart key with push-button start. There's a hidden high-security emergency blade tucked inside the fob for when the battery dies.
Identical smart key to the earlier generation. Three buttons, same high-security blade, same CR2032 battery. NISMO models use the same key system as the base.
Same physical smart key as previous years. The difference is under the hood in how the immobilizer communicates, but the key in your hand looks and works the same.

Fob Cell Drains Faster on the Z34 Than Most
Z34 fobs eat CR2032s faster than most Nissans, especially commuting with the fob next to your phone. Marco hits 619 Z owners in La Jolla and UTC who think the immobilizer died when it was the cell. Two-minute swap, ruled out first.
Immobilizer Sync Loss
People blame the fob when it is a desynced NATS immobilizer. Common on 2009-2016 models after a dead battery or jump. Key and car lose the handshake; OBD-II reprogramming fixes it. We handle it on-site in Carlsbad or Chula Vista.
High Security Blade Wear
Emergency blade feels loose in the door cylinder or won't turn. The high-security laser-cut blade on 2013-2020 models wears with regular use. We cut precise replacement blades on-site; quick fix, not a new key.
Can You Program the 370Z Key Yourself in San Diego?
You can knock out the lock and unlock buttons yourself running a key-cycle procedure, but the transponder chip that actually starts the car requires professional OBD-II programming. The DIY method only handles remote functions.
Same deal as the earlier cars. You can pair the remote buttons at home, but the NATS immobilizer won't accept a new transponder without diagnostic tools. That part needs a locksmith.
Remote button pairing works the same way, but the transponder programming on these later models may require server authentication on top of OBD-II access. Definitely not a DIY job.

San Diego Trivia Worth Knowing
Here is one San Diego Z owners can flex on: the 370Z was the very last production car on the planet to ship a naturally aspirated V6 mated to a true manual transmission. When Z34 production wrapped in 2020, that exact combination disappeared from every showroom from Carlsbad to Chula Vista. Every 370Z parked in 619 today is a unicorn of a configuration the industry abandoned.
