Notes & cautions
- GM PK3+ (Circle+) requires 4-digit GM security PIN. This chassis (Saturn Astra / Opel Astra H) spans both Americas and European markets — NASTF VSP covers North American VINs; European dealers use separate PIN lookup. Obtain NASTF / dealer / Tech2 PIN BEFORE arriving on-site.
- On-board 10-min cycle works on SOME early PK3 (not PK3+ rolling-code) — verify chip before attempting that path.
- GM PK3+ AKL: PIN MANDATORY. No on-board AKL path exists for PK3+ rolling-code.
- PIN sources: NASTF (preferred), AllData, dealer with proof of ownership.
- AKL erases existing key registrations — bring minimum 2 new key blanks.
Lockout
Door pick / decode: Lishi HU100 (CCW).
