Notes & cautions
- This chassis (Pontiac Bonneville 9th gen, 2000-2005) spans the GM Passlock era — uses resistor pellet (not transponder chip). Bonneville 9 shares GM G-body platform with Oldsmobile Aurora 2. On-board 30-minute relearn cycle with stable 12V+ is standard. Final Pontiac Bonneville generation.
- AKL via on-board cycle works — Passlock has no "all keys lost" lockout. No special tool needed if 30+ min available.
Lockout
Door pick / decode: Lishi B111 (CW).
