Volvo & Renault Unlock explained
The Schaknat App works with Volvo and Renault trucks built from 2013 onward (Euro 6). Before chiptuning your Volvo or Renault, the ECU must be unlocked. We can do this for you in three ways: through our mobile on-site service, by sending the ECU to us, or by using a special tool you can purchase from us.
The unlock itself is always free of charge.
