I assume that the code is for the radio/media system.
Quote:
"There's nothing worse than being locked out of your radio or media system. Well don’t worry, you have come to the right place.
All new Dacia's are supplied with the radio code, the code is printed inside the front or rear cover of the vehicle handbook or service book. If you don't have the hand book , or the code is not there. Here is the simplest way to obtain the unlock code and get back up and running:
1. Log into the My Dacia app. Navigate to > My Vehicle > Vehicle information and scroll down.
2. I don’t have a My Dacia account. Download the My Dacia app > Create your My Dacia account > Add your vehicle and then follow step 1."

Otherwise your daughter will need to pay to get the code from either a Dacia main dealer or online from a service such as this one (which is generally well-reviewed):
