2003 Chevrolet Malibu Remote Replacement - Fast, Affordable & Professional
Up near Montecito Peak Trail, a woman flagged me down in a parking area where she'd been sitting for about forty minutes. Her 2003 Malibu cranked fine but wouldn't catch. The SECURITY light on the dash was solid, then flashing, then solid again. She'd already tried the trick she found online: turn the key to ON, wait ten minutes for the light to go off, turn it off, repeat three times. It hadn't worked.
She told me she'd called a Chevy dealer earlier that week about something unrelated and asked about the security light while she had them on the phone. They told her to tow it in. Said the whole lock cylinder might need replacing and she'd be without the car for a day or two.
I checked the Passlock sensor wiring at the ignition harness first. On these fifth-gen Malibus, GM ran the Passlock III system with a Hall-effect sensor inside the column, and the connector is known for developing resistance over time. Hers had corroded pins at the sensor plug, which was throwing off the voltage the BCM expected to see. Cleaned the connector, confirmed the resistance reading was back in the valid range, ran the relearn cycle right there on the steering column.
Three start-kill-start cycles later, the SECURITY light went off and stayed off. She sat there watching the dash for a full thirty seconds before she believed it.
Her KOBLEAR1XT remote needed a fresh CR2032 anyway, so I swapped that while I was there. The whole visit took less time than her ten-minute relearn attempts had.
