TextM37 Key Security, Generation by Generation
Y51 Fifth Generation: NATS Smart Key
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.
What Key Does Your M37 Actually Use?
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.

Smart Key Battery Failure
First check on M37 push-button start issues in San Diego: the CR2032 inside the fob. Weak cell mimics a bigger problem. Marco swaps it curbside in Mira Mesa or Solana Beach, then OBD-II diagnostics if needed.
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 El Cajon or Escondido.
Can You Program a M37 Key on Your Own?
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.

A Quick Note
Here is one most San Diego M37 owners miss: Infiniti retired the M35 nameplate for 2011 and dropped the new 3.7L VQ37VHR V6 into the M37, picking up 27 horsepower over the outgoing car. The Intelligent Key system, though, stayed on the same NATS architecture, which is why Marco can move between an M35 and an M37 in the same afternoon without changing the tool loadout in the van.
