2010 Pontiac G5 Transponder Key Replacement - Fast, Affordable & Professional

I got a call from a guy parked near the border-crossing side of San Ysidro Village. He had one key left for his 2010 G5 and it snapped in half in the ignition. Not jammed, just snapped clean at the bow. The blade half was sitting in the cylinder and he'd already tried fishing it out with a tweezers. That made it worse.

He found me, called, and I was there in under an hour with the van.

First thing was extracting the broken blade. That's its own job before any key work even starts. Once it was out, I cut a fresh key to his vehicle using the lock code, then connected to the OBD port and walked the transponder chip through the programming sequence so the immobilizer would accept it.

He was watching and asked why the car would start and then die when he tried the hardware-store spare he'd had made months ago. I told him that's exactly what happens when the blade is right but the chip isn't enrolled. The immobilizer lets the engine crank, sees no valid chip, and shuts it down inside two seconds. He'd been blaming the battery.

The new key started the car clean on the first turn. He tested it twice more just to be sure.

The whole visit, extraction included, took about 40 minutes. He mentioned the dealer had quoted him a significant wait time just to get an appointment, on top of what they'd charge. He paid a fraction of that and didn't move the car an inch.
