For 2019+ Cadillac models, PIN code authorization from VIN is required. Autel retrieves PIN automatically. Smart key programming for Cadillac (all current models) includes both transponder chip and proximity fob in the same session.
Cadillac-specific quirks: Escalade uses larger smart key variant than CT-series sedans. CT5-V Blackwing and CT4-V Blackwing use standard PassLock - no special equipment for performance variants. Lyriq EV uses enhanced PassLock with EV-specific extensions.
