2003 Nissan Altima
Key Replacement - Save vs Dealer in San Diego

2003 Nissan Altima Transponder Key Replacement - Fast, Affordable & Professional

A web developer in Blossom Valley called me on a weekday afternoon. He works from home, and his 2003 Altima had been sitting at the top of a steep cul-de-sac since the night before. One key, and it had gone missing somewhere between his front door and the car.

He'd already called the dealer. They told him to bring the car in. He asked how he was supposed to do that without a key. The call ended there.

The street was narrow enough that I didn't even try to take the van up. I parked at the bottom and walked up with my bag. The Altima was sitting at an angle in his driveway, not going anywhere.

I pulled the security data through the OBD port, got what I needed from the immobilizer, cut a new key blade to match the door lock, and programmed the transponder chip to the car. The whole job was done on the driveway. He turned the key, it started on the first try, and he just sat there for a second like he wasn't expecting it to be that quiet and fast.

He mentioned the dealer quote while I was packing up. It was a lot more than what he paid me, and it assumed he could somehow get a car with no working key across town first.
