Cadillac XT5 Key Replacement
Cadillac XT5s have been on Dallas–Fort Worth roads since the 2017 era, and across 3 key generations this model has used 3 different key systems — smart proximity; hitag 2 ext./id46; smart proximity (5-btn). 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 XT5 Keys
The table below is our verified key reference for the Cadillac XT5 — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| XT5 / XT5-V | 2017–2021 | Smart proximity | Hitag2 Ext. / ID46E – FCC HYQ2EB (later HYQ2ES) | HU100 emergency insert |
| XT5/XT5-V | 2017-2021 | Hitag 2 Ext./ID46 | HYQ2EB/HYQ2EA | PCF7937E, PCF7961E (315/433 MHz) |
| XT4 / XT5 / XT6 | 2020–2025 | Smart proximity (5-btn) | ID46-class – FCC HYQ2ES (433 MHz), PN 13522879/13544052 | HU100 emergency insert |
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 XT5 specifically, the immobilizer families we see are: Hitag2 Ext. / ID46E – FCC HYQ2EB (later HYQ2ES), HYQ2EB/HYQ2EA, ID46-class – FCC HYQ2ES (433 MHz), PN 13522879/13544052. 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 XT5 Key FAQ
I lost the only key to my XT5. 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 XT5 call.
My XT5 is push-to-start. Can you really program that outside the dealer?
Yes. Late-model XT5s (2020–2025) use a proximity smart key on the ID46-class – FCC HYQ2ES (433 MHz), PN 13522879/13544052 system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My XT5 is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2017–2021 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 XT5 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.
