2004 Pontiac Bonneville Transponder Key Replacement - Fast, Affordable & Professional
Got a call from a guy near Historic Plaza Park in Oxnard. He had one working key left for his 2004 Bonneville and his wife had been asking him to get a spare for months. His words: "She's going to be right about this eventually."
He was parked on the street, finishing lunch. I pulled up and got started on the hood of my van. Cut a fresh B99 blade using his existing key as the reference, so the depths matched exactly. Clean duplicate, no guesswork.
Here is the thing with the 2004 Bonneville that a lot of people do not realize. The security is not in the key blade itself. It is Passlock II, which means the sensor is in the ignition lock cylinder reading a resistance value when you turn the key. The key does not carry a transponder chip the way a Toyota or Honda would. What it does carry is the remote head, the 15821273 unit with lock, unlock, and trunk buttons.
I programmed the new remote through the OBD-II port, paired it to his Body Control Module, and tested all three buttons plus the ignition cycle. No SECURITY light, no ten-minute lockout, everything clean on the first pass.
He texted his wife a photo of both keys side by side. Did not say anything else about it. Did not have to.
The whole job was about 20 minutes, right there on the street, for a fraction of what the dealer wanted.
