TANGO is the same as VVDI2 to program the keys have the same functions ??? or do I have to acquire both?

TANGO = Key maker by dump file and have some function for OBD2 in Toyota cars.

VVDI2 = Have key maker by dump file and you can active other functions by OBD2, like BMW and VAG group.

VVDI2 Basic came with PSA Group pincode reading (canbus cars) and Key maker by dump file.

If you want more function like a said before, need to active the other functions (€€€€).

To be a locksmith, You have to invest more than VVDI2 and Tango.

You will need for starters tools that worth 20 k euros.
