The Toyota key learning procedure is user-friendly and fully guided. When the Key Learning special function is selected, it is essential to follow all on-screen instructions exactly as they are displayed — following the prompts in the correct order is required for the procedure to complete successfully.

Supported operations: both spare key programming and all keys lost. Coverage applies regardless of market — US, European, UK and Asian versions are all supported. Smart system reset is not needed, and no connection to Toyota servers is required.

Required equipment

• Abrites AVDI interface
• Abrites OBDII cable (SAE J1962) – CB106
• Abrites ProTag programmer
• A transponder emulator matching the vehicle's key type:
  • TA64 – HITAG-AES (HT-AES)
  • TA68 – DST-AES
  • TA71 – Toyota "BA" type key (recommended), for 2021+ Tokai Riki smart systems with the TN014 licence
• CB012 – required for the latest models, see Additional Connections
• CB031 – extension cable for B9/BA smart systems (recommended)
• A stable power supply connected to the vehicle

Step‑by‑step procedure

The procedure runs via OBDII and is the same for any of the available Toyota licences — the only difference is the key transponder type used.

1. Begin the procedure

Press and hold the START button to begin.

2. Cycle the ignition

Switch IGN ON and then OFF, leaving the hazard lights ON.

3. Confirm the master key emulator

Confirm whether you want to prepare a Master Key emulator.

4. Read and modify the data

The software reads and modifies the required data.

5. Insert the emulator

Insert the HT-AES (TA64) key emulator into the ProTag programmer. Use the emulator matching the vehicle's transponder type.

6. Emulator prepared as Master Key

The TA64 is detected and prepared as the Master Key.

7. Switch ignition on with the emulator

Use the prepared TA64 to switch IGN ON.

8. Open the driver's door

Leave IGN in the ON position and open the driver's door.

9. Present the emulator

Touch the START button with the TA64.

10. Master Key detected

The TA64 is detected as Master Key.

11. Present the new key

Use the new key to touch the START button and learn it.

12. New key detected

The new key is detected.

13. Finished

The key is now learned and the procedure has completed successfully.

Important notes

• Follow the on-screen order exactly. The ignition, door and START-button steps are timing-sensitive; performing them out of sequence aborts the procedure.
• Choose the emulator by transponder type — DST-AES or HITAG-AES — not by model year alone.
• Some models need an internal CAN connection; see Additional Connections.
• To remove lost keys from the vehicle's memory, see Deleting keys.
