2022 Cadillac CT4 Replacement - Fast, Affordable & Professional
Got a call from El Presidio State Historic Park. Guy's CT4 decided the smart key didn't exist anymore. Dashboard kept flashing "No Remote Detected" every time he hit the start button.
He'd already changed the CR2450 twice. Still nothing. The dealer wanted him to flatbed it over and wait three days minimum. He had a client meeting in Montecito that afternoon.
I pulled up next to his white CT4 and grabbed the Smart Pro. First thing I noticed: his fob had the telltale crack along the seam where the emergency blade slides out. Water damage is real with these. Opened it up and sure enough, corrosion on the board contacts.
Could have cleaned it, maybe bought him another few months. But he needed reliability, not hope. Pulled out a fresh YG0G20TB1, ran the CAN-FD registration through the OBD port. The BCM accepted it on the first try. Cut the HU100 blade, tested all five buttons including the panic.
Twenty-eight minutes start to finish. He made his meeting. The dealer would have kept his car through Thursday at least, plus whatever they wanted to charge him.
