Nissan & Infiniti Intelligent Key + BCM Programming — Annetta TX
Nissan and Infiniti Intelligent Key replacement and BCM programming in Annetta TX. How Nissan anti-theft works, costs, and mobile on-site service.
Nissan & Infiniti Intelligent Key + BCM Programming — Annetta TX
Nissan and its luxury division Infiniti use a keyless system called Intelligent Key, and their anti-theft security leans heavily on the Body Control Module (BCM). If you drive an Altima, Rogue, Sentra, Maxima, Pathfinder, or an Infiniti Q50 or QX60, this guide explains how the Intelligent Key and BCM work together, what a replacement costs, and how we program them on-site. Call or text (817) 813-9396 for Nissan and Infiniti key service in Annetta, Weatherford, Aledo, and Fort Worth.
Quick Answer: Nissan & Infiniti Key Replacement
Nissan and Infiniti use transponder keys on older models and Intelligent Key proximity fobs on push-to-start models. The BCM plays a central role in reading the key and authorizing start through the immobilizer (NATS — Nissan Anti-Theft System). We program new keys and fobs to the vehicle on-site. With a working key, adding a spare is quick; all-keys-lost takes longer and involves accessing the BCM/immobilizer with a security code.

How Nissan & Infiniti Anti-Theft Works
Nissan's immobilizer is called NATS (Nissan Anti-Theft System). When you start the vehicle, the Intelligent Key or transponder communicates with the BCM, which coordinates with the immobilizer and engine controller to authorize starting. Because the BCM is central to reading and authorizing keys, BCM issues can cause no-start and security-light conditions — and a BCM replacement requires programming and re-enrolling keys. More on module-level work is in our module programming overview.
Bladed Transponder Keys
Older Nissan and Infiniti models use a bladed transponder key with NATS. These are quick to cut and program when a working key exists.
Intelligent Key Proximity Fobs
Push-to-start Nissan and Infiniti vehicles use Intelligent Key fobs for passive entry and start, with a hidden emergency blade for the door. We program the fob to the vehicle and cut the emergency blade. All-keys-lost on these takes more time.

Add-a-Key vs. All Keys Lost on a Nissan or Infiniti
With a working key, adding a spare is fast and inexpensive. With all keys lost, the mechanical cut is generated from the vehicle and the BCM/immobilizer accessed with a security code, which takes longer. See the all keys lost guide for the full process.
Why a Mobile Locksmith for a Nissan or Infiniti Key
Because the key programs to the vehicle, a dealer job usually means towing the car in and paying dealer prices. Our mobile unit comes to your driveway in Weatherford or your job in Fort Worth, cuts and programs the Intelligent Key on the spot, and typically charges less — no tow, no waiting room.
What to Have Ready
- Proof of ownership or authorization
- Year and model (VIN if handy)
- Any working key you still have
- The vehicle's location
Frequently Asked Questions
Can you program a Nissan Intelligent Key without the dealer?
Yes. We cut and program Nissan and Infiniti transponder keys and Intelligent Key proximity fobs on-site, including immobilizer enrollment, for most models.
My Nissan won't start and the key light is flashing — is it the BCM?
It can be. Because the BCM is central to reading and authorizing the Intelligent Key, BCM or immobilizer issues can cause no-start and security-light conditions. A dead fob battery or key fault is also common. We diagnose before recommending a fix.
How much is a Nissan Altima or Rogue key?
A transponder key runs roughly $120 to $220; an Intelligent Key proximity fob runs roughly $200 to $400. All-keys-lost is higher. Call for an exact quote.
Do I need my original Nissan key to get a spare?
No, but it helps. With a working key, adding a spare is faster and cheaper. Without any key, we can still build and program a new one — it just takes longer.
Will a new Nissan or Infiniti key cancel my old keys?
Adding a key normally leaves existing keys working. An all-keys-lost procedure re-initializes the key list, so previously lost keys stop working. We'll confirm which applies to your vehicle.
