TextHow Murano Keys Have Changed Over the Years
First Generation (Z50)
You turn this key in the ignition like any other key, but there is a hidden ID46 transponder chip inside the head that talks to the NATS immobilizer every time you start the engine. Without that chip handshake, the engine won't fire. Programming is done on-board, which keeps things straightforward and affordable.
Second Generation (Z51)
Nissan upgraded to a remote head key with an ID46 (PCF7936) chip and three buttons built right into the key head. Your lock, unlock, and panic buttons are all on the key itself, powered by a CR2025 battery. The NATS immobilizer moved to version 5, which means we need to pull a PIN code from the ECM before programming, but it is still an on-board procedure we handle in the driveway.
Third Generation (Z52)
This where Nissan got serious about security. Your Murano switched to a proximity smart key with an ID47 chip, push-button start, and five buttons. There's a laser-cut emergency blade tucked inside the fob, but day to day you never take the key out of your pocket. Programming requires OBD-II diagnostic equipment plugged into your vehicle's port.
Third Generation Facelift (Z52)
Same ID47 chip and five-button smart key as the 2015 to 2020, but Nissan updated the fob design and started leaning harder on server-based authentication for some programming tasks. We knock out these through OBD-II with the right credentials. The CR2032 battery and laser-cut blade carry over, so the emergency start procedure stays the same.
Fourth Generation
Nissan's newest Murano requires full server authentication for key programming. We can't do this one on-site. The 2025 needs dealer server access and we will tell you that upfront before we roll out. We're happy to help you figure out your options if you dial (619) 876-1271.
Identify the Key on Your Murano
A metal key with a hidden ID46 chip inside. No buttons, no battery. You insert it and turn it to start the engine.
Your lock, unlock, and panic buttons are built into the key head. The ID46 (PCF7936) transponder chip is inside, and the key still goes into the ignition to start the vehicle.
A rectangular fob that stays in your pocket or purse. Push-button start, five buttons, and a hidden laser-cut blade for emergencies. Uses an ID47 chip.
Same smart key concept as the 2015 to 2020 with an updated fob design. ID47 chip, push-button start, and a CR2032 battery you should swap out once a year.

NATS Handshake Lost, Security Light Stays Solid
Murano cranks but never fires, dash security light stays solid instead of clearing. On 2003-2014 Z50 and Z51 models, transponder lost ECM sync or the antenna ring is failing. Marco reads NATS codes curbside in El Cajon or Encinitas in minutes.
Key Fob Battery Drain
People think the smart key broke when it is a dead CR2032. On 2015-2024 Muranos, the fob constantly polls for the car, draining batteries fast. Swap first; if the problem returns in weeks, the fob's internal board is drawing too much current.
Steering Lock Module Failure
Steering lock actuator on 2015-2020 push-start Muranos can seize without warning. Fob detected, dash on, but engine refuses to fire because the column is mechanically locked. Not a key problem. We diagnose in Carlsbad or Encinitas.
PIN Code Retrieval Issues
We check NATS version first; PIN extraction changes by year. Early Muranos let us pull the PIN from the ECM with diagnostic tools. 2015+ may need CONSULT access or server creds. We arrive with Autel IM608 and the right subscriptions to get the PIN.
Can You Program the Murano Key Yourself in San Diego?
You can knock out the remote/keyless entry functions yourself with the ignition cycle method if you have one working key. But this only programs the remote buttons. The ID46 transponder chip still needs professional programming to start the engine.
Same deal here. The ignition cycle method lets you pair a new remote fob for lock and unlock, but the ID46 (PCF7936) transponder chip requires professional tools and a PIN code from the ECM. You can't DIY the part that actually starts the car.
No DIY option at all. The proximity smart key requires OBD-II programming equipment and a Nissan PIN code. There's no ignition cycle trick for these.
Same as the 2015 to 2020. Professional OBD-II programming only, with server authentication increasingly required. Don't buy a universal smart key off Amazon; it won't work.
The 2025 Murano requires full Nissan server authentication. This one is dealer-only for now. We will be upfront about that when you call.

San Diego Trivia Worth Knowing
Murano trivia that catches most San Diego owners off-guard: there is no 2008 model year. Nissan jumped from the 2007 Z50 first generation straight to the 2009 Z51 second-generation redesign, skipping 2008 entirely. So if anyone tells you they own a 2008 Murano cruising the 5 in 619, the VIN says otherwise. Worth a quick check on used-listing math.
