Your CT4 uses the same YG0G20TB1 smart key as the CT5 (434 MHz, ID49, CR2450, HU100 blade). The CT4-V and Blackwing variants use identical key hardware. There is no V-specific immobilizer or higher-security key tier.

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.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

Cadillac CT4 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my Cadillac?
Call a mobile locksmith, not the dealer. Cadillac dealer AKL quotes run $540 to $800 or more before you add towing, and they may not even get to it the same day. One Lyriq owner had their car at the dealer for ten days over a key detection issue. Independent Cadillac locksmiths commonly charge $200 to $500 for a lost smart key depending on the model and key type. We come to your location in San Diego, cut the key, run the GM theft deterrent relearn, program the transponder and remote functions, and test it all before we leave. No tow, no overnight, no Cadillac dealer markup.
