About ATS Keys

The table below is our verified key reference for the Cadillac ATS — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, so we always confirm the exact part by VIN before dispatching.

Security System & Immobilizer

Cadillac pioneered VATS resistor keys in the 80s and moved through PassKey and PK3 transponders to ID46 keys and today’s proximity fobs — every era still programmable on-site.

On the ATS specifically, the immobilizer families we see are: Hitag2 Ext. / ID46E (PCF7952E) – FCC NBG009768T, NBG009768T, 22856930, Hitag2 Ext. / ID46E (PCF7937E/PCF7961E) – FCC HYQ2AB, HYQ2AB/HYQ2AF. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Our ATS Key Services


Cadillac ATS Key FAQ

I lost the only key to my ATS. What now?

We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site. No tow, no dealer wait — this is our most common ATS call.

Will a hardware-store copy start my ATS?

It will open the doors and nothing else on transponder-era cars — the chip inside the key must be programmed to the immobilizer, which is the part we do curbside.

My ATS is older — do you still stock keys for it?

Yes. We carry blanks and chips going back to the 2013–2014 generation (smart proximity), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.

How fast can you reach my ATS in DFW?

We dispatch the nearest mobile unit across the whole metroplex, 24/7. Call (214) 717-6398 with your location and we’ll give you an honest ETA.
