🔧 PRO TIP
The 2016 ATS runs GM's PEPs (Passive Entry Passive Start) through the body control module, part number 13510553 on most builds. If you still have two working HYQ2AB fobs, you can add a third yourself using the GM relearn sequence: doors closed, press start twice without brake, hold lock and unlock on the new fob together. But if you're down to one or zero working keys, that method is locked out. You need a tech with SPS access to do the BCM relearn.

2016 Cadillac ATS Smart Key Replacement - Fast, Affordable & Professional

Got a call from a woman over in Bel Air Knolls neighborhood in Santa Barbara. Her 2016 Cadillac ATS smart key was falling apart. The chrome trim ring around the edge had cracked, the rubber button pad was lifting off the face, and the emergency blade wiggled in its slot like a loose tooth.

She had already been to the dealer. They quoted her for a full replacement fob, new programming, the whole package. Nobody mentioned that the internal circuit board and the transponder were working fine. She just needed a new house for the electronics.

I met her in the driveway with a replacement shell that fits the HYQ2AB and my HU100 Lishi for the Cadillac keyway. Popped the old fob open on her porch table. The board inside looked clean, battery contacts solid, no corrosion. Classic case of the shell dying before the brains do.

Moved the working circuit board into the fresh shell, pressed in new button pads, and cut a new emergency insert blade right there. Tested proximity unlock on both front doors, the trunk release, remote start, and the push-button ignition. Everything responded first try.

She kept turning the new shell over in her hands like she was waiting for something to be wrong with it. Nothing was. The expensive part of that fob, the programmed electronics, never needed replacing. She paid a fraction of what they wanted at the dealer for a job that took me about twenty minutes on her front porch.

Cadillac ATS Mobile Service FAQ

Real costs, no dealer surprises

I'm locked out of my 2016 Cadillac ATS with no spare key. Can you come to me in Santa Barbara?
Yep. I come to wherever the car is in Santa Barbara, including Bel Air Knolls neighborhood. I carry HYQ2AB blanks, the HU100 key cutter, and GM diagnostic access in the van. No tow truck, no waiting on Cadillac roadside, no getting transferred three times. I cut the emergency blade on site, program the new fob through the OBD-II port, and run the GM theft deterrent relearn so the BCM accepts the key. You drive away the same visit. The whole thing usually runs 30 to 45 minutes depending on whether it is a single key or all-keys-lost situation.
Do I have to tow my ATS to the Cadillac dealer for a new key?
What do I need to prove I own the vehicle before you make a key?
My ATS shows "No Remote Detected" but the fob battery is new. What is going on?
Can I buy a cheap HYQ2AB fob online and have you just program it?
