How to Program Toyota Avalon 2014 All Smart Keys Lost via OBD

Test report:  I’ve successfully programmed TMS37200 smart key on a Toyota Avalon 2014 Middle East model under all keys lost situation via OBD.

 

Main Procedure:

Step 1: Backup EEPROM with Lonsdor K518ISE

Step 2: Write key with Tango & SLK-03 emulator

Step 3: Add/register smart key with Lonsdor K518

(If you don’t have Tango, you can program smart key with K518 and Lonsdor SKE-IT Smart Key Emulator as well)
