Notes & cautions
- This chassis (Cadillac Escalade 2nd gen, 2002-2006) spans the GM Passlock era — uses resistor pellet (not transponder chip). Escalade 2 uses GMT800 full-size SUV platform shared with Chevy Tahoe/Suburban and GMC Yukon. On-board 30-minute relearn with stable 12V+ is standard.
- 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 GM37 (CW).
