🔧 PRO TIP
The 2023 CT4 runs a five-button remote with a CR2450 battery. The factory fob on the fob matches across the CT4 lineup, V-series included. No separate high-security tier for the performance trims. One thing that trips people up: the CR2450 is a thicker coin cell than the CR2032 you find in most fobs, so a convenience store substitution usually won't work. If the dash is throwing a key-not-detected warning and the fob feels sluggish, check the battery first, but make sure it's an actual CR2450, not a swap someone forced in. Also worth knowing: the remote and the ignition are separate systems. A fob with a dead battery can still start the car in some scenarios using the fob-to-start backup, but remote lock and unlock will be dead, which makes people think the whole key failed. It usually hasn't.

2023 Cadillac CT4 Key Replacement - Fast, Affordable & Professional

A woman over in Samarkand called me on a Tuesday morning. She'd come out to her CT4 in the driveway, hit the unlock button, and nothing happened. Car sat there, doors locked, no response from the fob at all.

She'd already swapped the battery. That was the first thing she told me, and I appreciated it because it moved us faster. She used a CR2032 she had in a drawer. That's the wrong cell for this fob, which takes a CR2450. Common mix-up because they look similar enough if you're not checking the number on the cell.

I pulled up in front of her place with the right battery already in my hand. Popped the fob, seated the CR2450 correctly, and she had remote function back inside two minutes. We tested every button, walked both doors, confirmed the car was responding normally.

She laughed a little when I told her what the issue was. Said she'd been convinced the whole key had died and was mentally prepared for a long day at the dealer.

It wasn't a long day. It was a Tuesday morning in Samarkand, fixed in her driveway, before she finished her coffee.

Cadillac CT4 Mobile Service FAQ

Real costs, no dealer surprises

How do I spot a fake locksmith before I get ripped off?
A few things that should send you looking elsewhere fast. If they won't give you a real estimate for your specific vehicle over the phone, that's a problem. Anyone working on Cadillacs should be able to give you a ballpark before they show up. If the quote is suspiciously low and they say they'll sort out the final price on-site, that's a bait-and-switch setup. Search the business name. If you find no real address, no reviews that mention GM or Cadillac work, or if the phone number routes to a call center with no local identity, move on. A legitimate mobile locksmith in Santa Barbara should have a verifiable local presence. Ask what tools they use for a 2023 CT4 specifically. A real tech can answer that without hesitating. If they stumble or go vague, they probably don't have what the job needs.
What exactly is a "remote" key and why can't I just copy it at a hardware store?
What equipment do you use to program Cadillac keys?
I bought a replacement fob online. Can I program it myself or do I need someone with equipment?
My CT4 sometimes starts fine but other times shows a key warning on the dash. The fob battery is new. What's going on?
