About DTS Keys
The table below is our verified key reference for the Cadillac DTS — 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 |
|---|---|---|---|---|
| DTS | 2006–2011 | Remote-head key | Hitag2 Ext. / ID46E (PCF7952E) | B111 / HU100 |
| DTS | 2006-2011 | Hitag 2 Ext./ID46E | 22889449, 5923877 | PCF7952E, NCF2951E |
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 DTS specifically, the immobilizer families we see are: Hitag2 Ext. / ID46E (PCF7952E), 22889449, 5923877. 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 DTS Key FAQ
I lost the only key to my DTS. 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 DTS call.
Will a hardware-store copy start my DTS?
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.
How fast can you reach my DTS 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.
