2024 Cadillac CT4 Replacement - Fast, Affordable & Professional
He was at the steakhouse in San Diego celebrating his anniversary when he realized his jacket was gone from the coat check. Keys, wallet, phone. He borrowed the host's phone, called the police, then his wife called me from her phone.
His 2024 Cadillac CT4 was in the lot with zero keys. The Cadillac dealer told his wife it would be 3 to 5 business days, the car needed to be towed in, and they recommended reprogramming the entire smart system since the stolen fob could still unlock the doors. Combined estimate was over $800.
I got there within the hour. All-keys-lost after a theft is a different procedure than adding a spare. I wipe the entire key memory so the stolen fob can no longer start the car or unlock the doors through the smart system. I used my IM608 to access the body control module, clear the old key data, and register two new fobs from scratch. His smart key, FCC ID YGOG20TB1, was a 5-button proximity fob. I decoded the lock, cut the emergency blade, and had both fobs working before the restaurant closed.
He drove home that night. Total was $97 for two new keys. The dealer estimated $211 plus a tow and nearly a week. The stolen fob is dead to the car.
