🔧 PRO TIP
The 2023 CT5 uses a 5-button smart fob with a CR2450 battery. That's a larger cell than most people expect, and the wrong size won't seat properly even if it looks close. When the fob starts acting flaky on these, the first thing to check is whether the battery has any corrosion on the contact tabs inside the housing. Even a small amount of oxidation on those tabs can kill the signal without fully killing the fob, so the car reads it intermittently or not at all. If you're in an all-keys-lost situation, this one needs diagnostic equipment to re-enroll the fob into the vehicle security system. No ignition-cycle trick is going to do it. Also worth knowing: the emergency insert blade stored inside the fob is your mechanical backup for the door if the fob dies completely, but it won't start the car on its own. Keep that in mind before you assume you're totally locked in.

2023 Cadillac CT5 Key Replacement - Fast, Affordable & Professional

He had just gotten cleared by the cardiologist and was walking back to the parking lot when his 2023 Cadillac CT5 went completely dark on him. Fob pressed, nothing. Held the fob near the start button as a backup read attempt, still nothing. It was late afternoon in Ramona, the dealer was already closed, and he had prescriptions to fill before the pharmacy shut down.

He called me.

I drove out to him in Ramona Highlands, got the door open, and connected my programming equipment through the OBD port. His 5-button smart fob had a CR2450 that had corroded one of the internal contact tabs just enough to drop the voltage below what the system would accept. It wasn't a dead fob. It was a fob that had given up right at the threshold. I replaced it, re-enrolled the new fob into the vehicle security system, and walked every function before I handed it back. Lock, unlock, remote functions, engine start, all of it.

From his call to engine running was about 50 minutes. The dealer would have been a morning appointment at best.

He made the pharmacy with 15 minutes to spare. When someone's just leaving a cardiology appointment and has a prescription window to hit, the timeline isn't flexible. That's exactly the kind of job I built this business around.

Cadillac CT5 Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Cadillac vehicles?
Yes. EZ Car Keyz holds a California Bureau of Security and Investigative Services license (LCO#6792) and carries full insurance. I'm also a NASTF Vehicle Security Professional, which matters on a late-model Cadillac because the vehicle security system on these requires verified credentials to access programming data legitimately. GM's newer platforms are not open to just any tool and any tech. Without proper credentialing and the right equipment, some of these vehicles simply cannot be programmed in the field. When you call me for a 2023 CT5 in Ramona, you're getting someone who already has the access and the equipment to finish the job on site.
How do I know you're not a scam locksmith?
Will the replacement fob work exactly like the original?
I bought a replacement fob online. Can you just program it, or do I need to buy one from you?
My CT5 shows a key warning on the dash even though the fob has a fresh battery. What's going on?
