P0513Incorrect Immobilizer Key
- Generic OBD-II code · Powertrain
- How the car detects it
- The engine module receives a secret code from the immobiliser or body module (Chrysler SKIM/SKREEM/RF hub, Saab CIM); if it does not match the stored code, P0513 sets and starting is prevented – Saab cuts fuel and blocks the starter. The most common trigger is a replaced or reflashed engine module that was not taught to the immobiliser (FCA, Saab), less often handshake timing on FCA hybrids or a key not programmed. FCA lists it as invalid SKIM key. It is not emission-related; CARB does not require immobiliser monitoring, and no source documents a warning lamp.
