🔧 PRO TIP
The 2019 ATS smart key (HYQ2AB, part 13580811) runs GM's PEPs system on a Hitag Pro ID49 chip with AES 128-bit encryption through the Body Control Module. A dying CR2032 throws "No Remote Detected" on the DIC and kills passive entry range before the start button stops responding. Swap the battery first, but check that the CR2032 contact tabs inside the fob housing aren't bent flat. GM TSB 15-NA-035 covers intermittent no-start from key detection issues on this platform, worth knowing before you assume the fob itself is dead.

2019 Cadillac ATS Smart Key Replacement - Fast, Affordable & Professional

Got a call from up in the Mission Canyon area in Santa Barbara. An ATS owner had one working smart key left after her other fob went through the wash a month earlier. She had been putting off the replacement because the dealer told her to bring the car in and leave it for half a day minimum, and the number they quoted her was steep enough to keep procrastinating.

Then the surviving fob started acting weird. Short range on the passive entry. Had to hold it against the start button to get the engine going. Classic CR2032 fade, but she didn't know that yet. She just knew she was one dead battery away from being locked out with zero working keys, and the all-keys-lost scenario on these is a bigger job for everyone involved.

I met her in her driveway. Popped open the working fob first. The CR2032 was original, three years old, voltage was low. Fresh battery brought that one back to full range immediately. She watched the door handle respond from ten feet away and her shoulders dropped about two inches.

Then I cut and programmed the replacement HYQ2AB through OBD using the Smart Pro. The BCM on the 2019 ATS accepts the new key, runs the theft deterrent relearn, and erases the old washed fob so it is permanently dead to the car. Whole visit was about 25 minutes.

She went from one half-dead key and a lot of stress to two fully working smart keys for a fraction of what the dealer wanted, without leaving her driveway.

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Cadillac ATS Mobile Service FAQ

Real costs, no dealer surprises

I am locked out of my 2019 Cadillac ATS with no spare. Can you come to me in Santa Barbara?
Yep. I come directly to wherever you and the ATS are in the Mission Canyon area. I carry HYQ2AB blanks, the cutting setup, and the diagnostic tools to program through OBD right at the vehicle. No tow truck, no dealer drop-off, no sitting on hold with Cadillac roadside. I give you a real arrival window and I show up. Most lockout-to-new-key jobs on these run about 30 to 45 minutes depending on whether it is a single key or all-keys-lost situation.
Do I need to tow my 2019 ATS to the Cadillac dealer for a new key?
What do I need to prove ownership before you make a key?
My ATS dash says "No Remote Detected" but the battery is new. What is going on?
Can I program a replacement HYQ2AB smart key myself on the 2019 ATS?
