About DeVille Keys
Verified key reference for the Cadillac DeVille — 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 |
|---|---|---|---|---|
| DeVille / Seville / Eldorado | 1989–1999 | VATS/PassKey resistor key (no transponder) | VATS resistor pellet (15 values) – not a chip | B62-P mechanical (resistor pellet) |
| DeVille | 1991-1999 | VATS/PassKey | — | Anti-theft system |
| DeVille | 2000–2005 | Transponder (no remote in key) | Megamos 13 / ID13 – PassKey III | B106/B107 (GM 10-cut) – confirm by VIN |
| DeVille | 2000-2005 | MEGAMOS 13/ID13 | — | PassKey III system |
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 DeVille 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.

Cadillac DeVille Key FAQ
I lost the only key to my DeVille. 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 DeVille?
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 DeVilles?
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.
