2001 Nissan Sentra Transponder Key Replacement - Fast, Affordable & Professional

Out in the East End of Ojai, I got a call from a guy who'd been sitting on his driveway for about an hour before he reached out. His 2001 Sentra had been his daily driver for years and he was down to his last key, which had finally given up. Not lost, just dead to the car. It would turn in the ignition fine, the engine would crank, and then nothing. Shut right off. He figured it was electrical, maybe fuel, and had already called a tow.

I told him to cancel the tow and stay put.

When I got there, the key was original, worn down from years of use, and the transponder inside had almost certainly failed. The ignition cylinder was reading the blade fine mechanically, but the immobilizer wasn't getting the handshake it needed to release the engine.

I cut a new key to match his ignition, programmed the transponder to his vehicle's immobilizer right there in the driveway, and tested it through several cold start cycles before I packed up. The car started clean every time.

He'd been quoted a dealer visit that involved towing the car in, leaving it overnight for a technician to look at it the next morning, and paying separately for diagnosis, the key, and programming labor. His total with me was a fraction of what the dealer had floated as an estimate, and he didn't have to arrange a ride or miss a shift.
