Security System & Immobilizer

Cadillac pioneered VATS resistor keys and moved through PassKey and PK3 transponders to ID46 keys and today’s proximity fobs.

On the Seville specifically we see: VATS resistor pellet (15 values) – not a chip, Megamos 13 / ID13 (PassKey III). 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?

  • 1989–1999: VATS/PassKey resistor key (no transponder) — VATS resistor pellet (15 values) – not a chip (B62-P mechanical (resistor pellet))

  • 1998–2005: Transponder — Megamos 13 / ID13 (PassKey III) (B106/B107 (GM 10-cut) – confirm by VIN)

Cadillac Seville Key FAQ

I lost the only key to my Seville. 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 Seville?

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 Sevilles?

Yes — back to the 1989–1999 generation (vats/passkey resistor key (no transponder)), and a fresh code-cut key beats any copy of a worn original.
