2020 Cadillac CT4 Replacement - Fast, Affordable & Professional
Got a call around 8:15 in the morning from an insurance agent near Cottage Hospital in Santa Barbara. Her 2020 CT4 was sitting in the office lot, push-to-start completely dead, and she had a client showing up at 9. No wiggle room.
I made it to her in about 20 minutes. The CT4 was locked and unresponsive to the fob, so I decoded the HU100 keyway with my Lishi tool and got the door open. Inside, I connected through the OBD port and pulled the immobilizer status. The Body Control Module, GM part number 13529177 on these Alpha platform cars, was not seeing the key at all.
Popped her YG0G20TB1 open on the hood. The CR2450 was original, almost three years old, and voltage was down to nothing. Swapped the cell and ran the reprogram through the BCM to clear the communication fault and re-register the fob. Hands-on time was maybe 20 minutes.
I tested all five buttons, push-to-start, and walked the perimeter checking passive entry on every door handle. Everything came back clean. Handed her a spare CR2450 for the glovebox so she would not get stuck like this again.
She made her 9 o'clock meeting. Texted me that afternoon just to say thanks. The dealer alternative would have been a tow, a lost morning, and a bill for way more than what this cost her.
