2015 Chevrolet Tahoe Smart Key Replacement - Fast, Affordable & Professional

Out in Oxnard Shores, I got a call from a guy whose Tahoe had been sitting in his driveway for two days. He had one fob left and it stopped starting the car. The push-button gave him nothing. No crank, no warning light telling him what was wrong, just silence.

When I pulled up, he handed me the fob before I even asked. I popped it open right there on the hood of my van. The CR2032 was showing low voltage on my meter, borderline, the kind that reads just alive enough to lock and unlock from three feet but not enough to get through the start sequence. Swapped the cell. Still nothing.

That told me the fob itself had a problem, not just the battery. I pulled up my diagnostic tool, connected to the OBD port, read the security data out of the body control module, and walked through the key relearn sequence. There's a security access timer built into the process on these and you just have to wait it out. No skipping it.

After the relearn completed, I tested the way I always do. Every button. Walking the length of his driveway for range. Three cold starts. He was watching from the front step with his arms crossed, not quite believing it would work.

Third start, he uncrossed his arms.

The dealer had told him over the phone that he'd need to tow it in and come back the next day. We finished the whole thing on site, in his driveway, for a fraction of what they quoted.
