2019 Chevrolet Spark Smart Key Replacement - Fast, Affordable & Professional

I got a call from a woman parked near the shopping strip in San Ysidro Village. Her Spark fob had been acting up for a week, then one morning it just stopped. No lock, no unlock, nothing. She'd already tried a fresh CR2032. Still nothing.

When I pulled up, she had the emergency blade out and was getting in the old-fashioned way. The car would start, but the fob sat dead in her hand.

I connected my diagnostic tool to the OBD port and pulled up the vehicle security system. The fob wasn't pairing at all. The previous battery swap had gone wrong somewhere, and the fob's internal contact had taken some damage from being pried open the wrong way. The fob itself needed replacing, not just the battery.

I had a compatible five-button fob with me. Read the security data, ran the key learn sequence, let the security timer do its thing, enrolled both the new fob and confirmed the original blade still matched the door lock. Then the part that matters: I walked the whole lot. Lock from across the parking lane, unlock, panic, remote start function, and three clean ignition cycles to make sure nothing was intermittent.

She watched the whole thing from about twenty feet away, arms crossed, not fully believing it was going to work until the third cold start turned over clean. That's usually when people relax.

The dealer had quoted her a number that made her put the phone down. She paid a fraction of that, and I came to her.
