hello guys has anyone seen this unit and know how to make a key from it. i see no chip in this box with a mass number that im familiar with .what can I do to program a key for this car...it is said to have a st chip that is locked

[simaservis1108]

Keys are stored in ST72C which is locked.
Make ECU virgin and replace immobox for another one(Black ID48 for example).
Then make keys from new immobox dump.

Regards,
Sima

First step is to find ECU for that car and check if it can be made virgin.
When you find it,make photos and upload so I can check if can be made virgin.
