Cadillac ATS Key Replacement
Cadillac ATSs have been on Dallas–Fort Worth roads since the 2013 era, and across 4 key generations this model has used 3 different key systems — smart proximity; hitag 2 ext./id46; hitag 2 ext./id46e. Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
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.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| ATS | 2013–2014 | Smart proximity | Hitag2 Ext. / ID46E (PCF7952E) – FCC NBG009768T | HU100 emergency insert |
| ATS | 2013-2014 | Hitag 2 Ext./ID46 | NBG009768T, 22856930 | PCF7952E, PCF7941E |
| ATS / CTS / XTS | 2014–2019 | Smart proximity | Hitag2 Ext. / ID46E (PCF7937E/PCF7961E) – FCC HYQ2AB | HU100 emergency insert |
| ATS | 2015-2019 | Hitag 2 Ext./ID46E | HYQ2AB/HYQ2AF | Keyless GO (315/433 MHz) |
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.

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.
