Buick Enclave Key Replacement
Buick Enclaves have been on Dallas–Fort Worth roads since the 2008 era, and across 5 key generations this model has used 4 different key systems — transponder key; “philips crypto 2 / hitag 2 / id46”; “hitag2 extended / ~id46, id46e / pcf7952e, pcf7961e”; smart / proximity (peps). 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 Enclave Keys
The table below is our verified key reference for the Buick Enclave — 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 |
|---|---|---|---|---|
| Enclave | 2008–2017 | Transponder key | Philips Crypto 2 / Hitag2 / ID46 | B111 / B106 (GM45) |
| Enclave | 2008-2017 | “Philips Crypto 2 / Hitag 2 / ID46” | Transponder key | |
| Enclave | 2017-2020 | “Hitag2 Extended / ~ID46, ID46E / PCF7952E, PCF7961E” | Remote head key | |
| Enclave | 2018–2020 | Smart / proximity (PEPS) | Hitag2 Extended / ID46, ID46E | HU100 emergency insert |
| Enclave / Encore / Envision / Envista | 2021–2025 | Smart / proximity (PEPS) | confirm by VIN (GM PEPS) | HU100 emergency insert |
Security System & Immobilizer
Buick uses GM’s security systems by era: PassLock cylinders with plain keys, PK3/PK3+ transponders, ID46 keys, and current proximity fobs.
On the Enclave specifically, the immobilizer families we see are: Philips Crypto 2 / Hitag2 / ID46, Transponder key, Remote head key, Hitag2 Extended / ID46, ID46E, confirm by VIN (GM PEPS). 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.

Buick Enclave Key FAQ
I lost the only key to my Enclave. 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 Enclave call.
My Enclave is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Enclaves (2021–2025) use a proximity smart key on the confirm by VIN (GM PEPS) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My Enclave is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2008–2017 generation (transponder key), 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 Enclave in DFW?
