OEM Remote Starter: Before programming your module, you must first check if your vehicle is equipped with an OEM remote
starter and disable it. If the vehicle is equipped with an OEM remote starter, whether Active or Inactive, it MUST be temporarily
disabled or permanently disconnected depending on the vehicle. Please refer to the “OEM remote starter information” section of the

OEM remote starter information
If the vehicle has an active OEM remote starter it will program into convenience only (no immobilizer bypass). The reason for this is to allow
aftermarket security to be installed while keeping the factory remote starter active. If you wish for the interface to control the remote start sequence,
perform one of the following:
If the vehicle is equipped with a physical add-on Lexus/Toyota OEM Remote Starter
Some Lexus/Toyota vehicles may have an Add-On remote starter. If the OEM unit is installed, whether Active or Inactive, it MUST be permanently
disconnected, as both modules cannot coexist. Refer to 'Physical OEM remote start locations" in the chart below and always physically inspect
and disconnect any OEM remote starter before programming any Directed products.
If the Vehicle is Equipped with an OEM Remote Starter:
If the vehicle is equiped with an OEM RS, the module will detect it and won’t complete the programming sequence in order to prevent OEM RS
to lose its programing. To complete the module programming you need to disconnect the OEM RS. refer to led diagnostic.
