About Avalanche Keys
Verified key reference for the Chevy Avalanche — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Avalanche | 2007–2013 | remote-head / flip | Philips Crypto 2 / Hitag2 / ID46 | B111 / HU100 (confirm by VIN) |
Security System & Immobilizer
GM security moved from VATS resistor keys through PassLock to PK3/PK3+ transponders, the ID46 “Circle+” era, and today’s proximity fobs.
On the Avalanche specifically we see: Philips Crypto 2 / Hitag2 / ID46. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.
Which key does your year have?
- 2007–2013: remote-head / flip — Philips Crypto 2 / Hitag2 / ID46 (B111 / HU100 (confirm by VIN))

Chevy Avalanche Key FAQ
I lost the only key to my Avalanche. 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.
Will a hardware-store copy start my Avalanche?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
