Need assistance with immobilizer reprogramming from tech. Any Lexus techs out there? Not real familar with reprogramming key codes. Have 99 ES300 that we replaced the ecm with a used unit. Having no luck trying to erase the existing key codes in the ecm and reprogram the existing key. Using Vertronix with Toyota card. Have TSB #SS606-99. Keeps saying key registrarion failed.
Deleted B2795, then follow prompts in clearing old codes and registering existing key. No other codes. We replaced the origional ECM cause it said all 6 ignightors were bad, backprobing ECM test said it was at fault. Thanks.
