Preparing a virgin transponder as a Toyota/Lexus/Scion MASTER key (Production menu)

Keys ordered from Toyota/Lexus/Scion dealers are in most cases SLAVE keys and are unusable after an immobiliser reset. The "Production" utility lets you program a virgin transponder as a MASTER key, ready to be accepted by the immobiliser.

Procedure

1. Connect the PROTAG to the PC, open the "Transponder Tool" special function and select "Production".
2. Use a virgin (new) Texas 4D transponder or a TPX2. A TPX1 is only needed for preparing the "Emergency 4C" key.
3. During preparation choose what kind of key you need - master key or sub key - and which vehicle model it is for.
4. Choose the correct type according to the market: ID67 for Toyota/Scion, ID68 for Lexus, ID70 for Toyota Europe. For G-type keys use the "DST80/DST+" menu, for 4C keys the "Tiris 4C/4D" menu.
5. Program the transponder and check it with "Read/Identify" before taking it to the car.
6. Apply the rules that hold for all Toyota/Lexus/Scion: at least one MASTER key must be registered in the immobiliser; after a system reset the first key programmed must be a MASTER; in many cases at least two registered keys are needed to close the learning.
7. On older vehicles with an external immobiliser and 4C key, Abrites recommends always keeping a universal key generated from the "Production" menu to hand: with it you can add a new key without removing the immobox.
