Buick Encore Key Replacement
Buick Encores have been on Dallas–Fort Worth roads since the 2014 era, and across 5 key generations this model has used 4 different key systems — remote-head flip key; “hitag2 extended / ~id46, id46e / pcf7937e, pcf7941e”; smart / proximity (peps); “hitag2 extended / ~id46, id46e / pcf7952e, pcf7961e”. 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 Encore Keys
The table below is our verified key reference for the Buick Encore — 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 |
|---|---|---|---|---|
| Encore | 2014–2019 | Remote-head flip key | Hitag2 Extended / ID46, ID46E | HU100 (B111-family) |
| Encore | 2014-2020 | “Hitag2 Extended / ~ID46, ID46E / PCF7937E, PCF7941E” | Remote head key | |
| Encore | 2017–2021 | Smart / proximity (PEPS) | Hitag2 Extended / ID46, ID46E | HU100 emergency insert |
| Encore | 2017-2021 | “Hitag2 Extended / ~ID46, ID46E / PCF7952E, PCF7961E” | Remote head key | |
| 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 Encore specifically, the immobilizer families we see are: Hitag2 Extended / ID46, ID46E, Remote head key, 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 Encore Key FAQ
I lost the only key to my Encore. 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 Encore call.
My Encore is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Encores (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 Encore is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2014–2019 generation (remote-head flip 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 Encore 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.
