2003 Pontiac Bonneville Transponder Key Replacement - Fast, Affordable & Professional
Got a call from down at Fisherman's Wharf at the Harbor in Oxnard. Guy was loading gear back into his 2003 Bonneville after a morning on the water and his key just snapped. Not the transponder head, the actual blade. Broke right at the shoulder where it meets the bow. He had the head in one hand and the blade was stuck in the ignition cylinder.
I got there and pulled the broken blade out of the B99 cylinder with an extractor. No damage to the wafers. The transponder chip in the broken key head was still good, but there's no reusing a snapped blade, so I cut a fresh B99 blank and programmed the new PK3 transponder through the OBD-II port. The Bonneville's Theft Deterrent Module (TDM) on the H-body picks up new keys pretty clean as long as you have a working key or the right diagnostic access.
He stood there watching me work on the dock railing, holding a bucket of tackle, and when the car fired up on the first turn he just quietly set the bucket down like he'd been holding his breath. Didn't say much. Just nodded.
The whole thing took maybe 25 minutes. He asked what the dealer would have done. I told him they'd want the car towed in first, then a day or two wait. He picked his bucket back up and drove home.

Why Pontiac Customers Skip the Dealer
Real reviews from real locations
“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”
“Niv showed up, did his thing, and just like that I had two new keys for a fraction of what the dealership quoted. I have zero reservations recommending him to anyone who needs car keys replaced.”
