I complete the programming and process dcryptor data enabling options C1 and D1 as per instructions. When I return the module to the vehicle and attempt remote start (LOCK x3) The Theft Deterrent System notification comes up and the vehicle will not start. When I hold the key to the tumbler the vehicle will start however the Theft Deterrent System notification still appears.<br /> <br /> I take this to mean that there is an issue with the dcryptor information so I&#039;m wondering what I need to do.
