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 will not 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 your driveway.
Third Generation (Z52)
This is 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 is 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 handle 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 cannot do this one on-site. The 2025 needs dealer server access and we will tell you that upfront before we roll out. We are happy to help you figure out your options if you call us at (805) 790-8162.
Which Key Does Your Murano Use?
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.
Nissan's newest smart key with advanced NATS security. This model currently requires dealer programming.

NATS Immobilizer Failure
Murano cranks but won't start, or security light stays solid. On 2003-2014 models the transponder lost sync with the ECM, or the antenna ring around the ignition barrel is failing. We read NATS codes on-site and name the failed part 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 won't start because the column is mechanically locked. Not a key problem. We diagnose in Simi Valley or Camarillo.
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 a Murano Key Yourself?
You can program the remote/keyless entry functions yourself using 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 cannot 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 is no ignition cycle trick for these.
Same as the 2015 to 2020. Professional OBD-II programming only, with server authentication increasingly required. Do not buy a universal smart key off Amazon; it will not 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.

Did You Know?
You would not guess it, but the Nissan Murano skipped the 2008 model year entirely. Nissan jumped straight from the 2007 first generation to the 2009 second generation redesign. So if someone tells you they have a 2008 Murano, they are mistaken.
