About Astra Keys

Verified key reference for the Saturn Astra — 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

Most Saturns use GM PassLock — plain key, sensor in the ignition cylinder — while the 2007–2010 wave (Aura, Outlook, Sky, Astra, Vue) moved to true transponder keys.

On the Astra specifically we see: ID46. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Saturn Astra Key FAQ

I lost the only key to my Astra. 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 Astra?

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