2015 Porsche 911 Smart Key Replacement - Fast, Affordable & Professional

There is a stretch of high-rises along Coronado Shores where the parking structure faces the water and the wind off the bay is constant. I pulled in on a Saturday morning for a 2015 Porsche 911 with a cracked fob housing.

The owner had discovered the crack after dropping it on a tile floor, and somewhere in the fall the internal contact board had shifted just enough that the key-not-detected warning was showing up intermittently at start.

He had already ordered a replacement fob online, which was the right instinct, but it was sitting in a box on his passenger seat unprogrammed. He figured someone could just plug it in.

I explained what the job actually looked like. On the 991, adding a key to an existing working setup requires diagnostic equipment to communicate with the immobilizer and register the new fob. No ignition sequence, no button trick. I paired the new fob on site, tested every button, ran three clean starts from different distances, and confirmed the emergency blade was cut correctly to his door lock.

The cracked fob got erased from the system. No point leaving a damaged key registered that someone else could potentially use.

He mentioned he had called the Porsche dealer in the area first. They told him the key had to be ordered, and scheduling was two weeks out. He had found me before making that appointment, and we had the whole job done before noon. He walked back to his unit while I was still packing up the van.
