Hi everyone, I have a Japanese import Subaru WRX S4 GT-S Eyesight (2015). Original key: • Subaru smart key part number: 14AHA-01 • Frequency: 312.15 MHz FSK (JDM) • Push start + Eyesight I bought a genuine replacement key (same part number) from China, but it cannot be programmed. The car does not recognise the transponder at all. What I’ve tried: • Local UK auto locksmith – failed (no transponder detection) • Subaru UK dealer – confirmed they cannot program JDM keys • Advised to contact Subaru Japan I understand this is a JDM immobiliser / SSM issue rather than just a remote pairing problem. Question: Has anyone in the UK/EU successfully programmed JDM Subaru smart keys (WRX S4 / Levorg / JDM Impreza, 312MHz)? Or knows a specialist / importer / locksmith who can handle JDM immobiliser programming (SSM3/SSM4, EEPROM, ECU bench work, etc.)? Any advice or contacts would be hugely appreciated. Thanks in advance!
