Notes & cautions
- This chassis (Cadillac CTS 2nd gen, 2008-2013) spans GM PK3+ Circle+ rolling-code era — uses GM Sigma II RWD platform. 4-digit GM security PIN REQUIRED. Sources: NASTF VSP, AllData on-demand, GM Tech2 dealer, K518 built-in PIN list. Coupe + Sport Wagon variants share the same IMMO platform.
- On-board 10-min cycle works on SOME early PK3 (not PK3+ rolling-code) — verify if attempting that path.
- CTS 2 YAML chip data may be incomplete — most 2008-2013 CTS use PK3+ ID46.
- 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 B111 (CW).
