First, start up the Tango transponder key programmer, connect it to your computer and find “read information” in the “Info” window. Watch memory chip showed in the Data location field. Find out the chip inside of the immobilizer and read it. Save the read data (dump).
Click the “Open Immobilizer File” button and upload the dump.
Tango system will analyze the dump automatically.
If the dump you saved is correct, the “WRITE” button will be actived and the “Keys” window will display the range of key numbers that can be created.
Check the allowed transponder field, and make sure you use a right transponder.
Put the transponder into the coil (the square hole on the tool).
Choose the key bites you want create in the “Keys” window.
Click the “WRITE” button.
The Obd2 Key Programmer transponder will then be written automatically, with data stored.
Save a new immobilizer dump after a new transponder is made.
Save the file after a standard File Save dialog pops up.
