2018 Chevrolet Express Transponder Key Replacement - Fast, Affordable & Professional

Up near Serra Cross Park in Ventura, I got a call about a 2018 Express that was starting and dying. The owner had been running a small cleaning business out of it and one of her employees had gotten a spare key made somewhere fast and cheap. The blade was cut well enough that it turned the ignition fine. But the engine would fire, run for about two seconds, and shut off. Every time.

She had already paid a shop to look at it. They scanned it, saw a security-related fault, and told her it might be a fuel pump issue or a wiring problem. She spent a week chasing that before someone on a forum mentioned the key.

I drove out to the parking area off Ferro Drive, close enough to the park that you could hear the wind in the trees. She showed me both keys. The original was worn but still worked. The copy turned the ignition the same way but triggered the security system every time, which cuts the engine as designed. The transponder chip in the copy had never been programmed to the van. It was a blank. The blade was right. The chip was dead weight.

I cut a new key to match the ignition, programmed the transponder to her van on site, and verified it through several start cycles before I packed up. She tested it herself, started it twice, and just nodded.

The dealer had been mentioned once during the conversation. She said they quoted her a wait of several days and a price she described as "not happening." She found me instead, I was there in under an hour, and the whole job was done before she had to be back at a client's house.
