About Sunfire Keys

Verified key reference for the Pontiac Sunfire — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.

Security System & Immobilizer

Pontiacs use GM security of their era — VATS on older performance cars, PassLock plain keys, and PK3/ID46 transponders on the final generations.

On the Sunfire specifically we see: PassLock — no key chip (Hall-effect lock sensor, not a transponder). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Pontiac Sunfire Key FAQ

I lost the only key to my Sunfire. 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 Sunfire?

On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
