Infiniti M37 Key Replacement in Ventura County (2011-2013)

Q: What type of battery does the M37 smart key use?

It is a CR2032 coin cell battery. You can grab one at any pharmacy or hardware store for a few bucks. Slide the release switch on the side of the fob, separate the halves, and swap the battery with the positive side facing up. If your remote buttons stopped working but the car still starts when you hold the fob against the push button, a dead battery is almost certainly the problem.

Q: Are there different key types for different M37 trims?

No, and that is actually good news for you. Whether you have the Base, Premium, Premium Touring, or Sport trim, the Intelligent Key is identical across the board. Same fob, same ID46 chip, same laser-cut blade, same programming process. Higher trims might link the key to memory seat positions, but the physical key and the way we program it does not change. One key type, one price, no surprises.

How Infiniti Secured Your M37

Y51 Fifth Generation: NATS Smart Key

2011-2013

Your M37 uses an ID46 transponder chip inside a smart key fob with push button start. The NATS immobilizer system requires server authentication to program a new key, which means no shortcuts and no DIY workarounds. It is a serious security setup, and it takes professional tools plus a live server connection to get a new key paired to your car.

Which Key Does Your M37 Use?

🔑

Infiniti Intelligent Key (Smart Key)

2011-2013

A slim fob with three buttons and a hidden emergency blade inside. You never insert it anywhere; just keep it in your pocket and press the start button. The blade is laser-cut, which means only a precision cutter can duplicate it.

The Real Cost of an M37 Key

Price includes the key blank, precision blade cutting, NATS server programming, and full testing before we leave your driveway.

Common M37 Key Problems

🔋

Smart Key Battery Failure

First check: the CR2032 inside your fob. Weak battery causes intermittent push-button start failures that feel like a bigger problem. Pop the fob and swap. If that fails, call (805) 790-8162.

🔒

NATS Immobilizer Malfunction

M37 owners get told they need a new ECU when the car will not recognize their key. Almost never. Real culprit is usually a glitch between the ID46 transponder and the NATS module, fixed with an ECU reset and reprogramming.

🔑

High Security Blade Wear

M37 emergency blade feels loose or sticky after regular use following a dead fob. The laser-cut profile wears down, leaving you locked out. We carry Ilco precision cutters and cut a fresh blade in Simi Valley or Camarillo.

Can You Program an M37 Key Yourself?

2011-2013 (Y51)

No - Pro Required

No DIY method exists for the M37. The NATS immobilizer requires server authentication and a professional diagnostic tool like the Autel IM608 to register a new smart key. You will need either a dealer or a locksmith with the right equipment.

Infiniti M37 Key Questions

Can I program a replacement Infiniti M37 smart key myself? ▼

If you are hoping for a YouTube tutorial that walks you through it, you will not find one that works. The 2011-2013 M37 uses the NATS immobilizer with server authentication, which means the key has to be registered through a professional diagnostic tool connected to a live server. There is no on-board add-a-key procedure, no button sequence, no workaround. Call us at (805) 790-8162 and we will handle the programming on-site with our Autel IM608.

What type of battery does the M37 smart key use? ▼

Does the M37 have push button start, and does that affect key programming? ▼

Yes, every 2011-2013 M37 has push button start as standard equipment. And yes, it absolutely affects programming. The car has to recognize your smart key's proximity signal and transponder code before it will let the engine start. That is why programming requires professional equipment; the key needs to be coded to both the immobilizer and the proximity detection system, not just the remote lock and unlock functions.

💡

Did You Know?

Back in 2011, Infiniti retired the M35 nameplate and introduced the M37 with a significantly upgraded 3.7L V6 engine. That swap added 27 horsepower over the outgoing model, a jump that made the M37 one of the more spirited luxury sedans in its class. The Y51 platform also underpinned the Nissan Fuga sold in Japan, making it a genuinely global car with different badges depending on which side of the Pacific you were standing on.
