About Park Avenue Keys
Verified key reference for the Buick Park Avenue — 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 |
|---|---|---|---|---|
| Park Avenue | 1991-1996 | “VATS / PassKey Anti Theft System” | Mechanical key | |
| Park Avenue | 1997–2005 | Transponder key | Passkey 3 (PK3) / Megamos Crypto 48 | B99 / B102 (GM39) |

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 Park Avenue specifically we see: Mechanical key, Passkey 3 (PK3) / Megamos Crypto 48, Transponder key. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Buick Park Avenue Key FAQ
I lost the only key to my Park Avenue. 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 Park Avenue?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
Do you still stock keys for older Park Avenues?
Yes — back to the 1991-1996 generation (“vats / passkey anti theft system”), and a fresh code-cut key beats any copy of a worn original.
