2003 Nissan 350z REMOTE-HEAD-KEY Replacement - Fast, Affordable & Professional

Do you need to tow your 2003 Nissan 350z to the dealer? Probably not. For most Nissan models from the mid-2000s through the late 2010s, I handle all-keys-lost right at the car.

A swing shift electrician in Rancho Santa Fe had his only key die at home late at night. His 350z was in the mobile home driveway with push-to-start and no fob the car would recognize. He assumed a tow was inevitable and started looking up costs and planning his week around getting to work without a car. I told him to stay put and that I'd come to him.

I connected my Smart Pro to OBD and ran the Nissan Intelligent Key AKL procedure, which walks through the immobilizer handshake, erases old key data, and learns new fobs. His REMOTE-HEAD-KEY, FCC ID CWTWB1U751, was a 4-button proximity fob with an emergency insert. I programmed it in his driveway at 11:30pm. He seemed pretty surprised it could happen right there.

His total was about $185. Dealer would have been $395 plus the tow. There are a small number of very new Nissan models with AES encryption where my tools don't have AKL coverage yet. Those do need the dealer. But for the majority of Nissans on the road, 2005 through about 2021, I do all-keys-lost on-site. If yours is an exception, I'll tell you straight up.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

Nissan 350z Mobile Service FAQ

Real costs, no dealer surprises

My key broke in the ignition. Can you get it out?
Yes. Broken key extraction is a standard job for a mobile automotive locksmith. We use specialized tools to remove the broken piece without damaging your Nissan's ignition cylinder. One locksmith familiar with Nissans warns that once a key breaks off inside, the wafers and channel inside the ignition can get damaged, and even if the broken piece comes out, the cylinder may need replacement soon. Once the piece is out, we can cut a new key from the extracted fragment or from your vehicle's lock data and program it on the spot. Nissan models that still use a physical ignition key are most likely to run into this.
