If your Renault or Dacia radio asks for a security code after losing power, first check the vehicle handbook, then use the manufacturer’s app. Both routes can be free. The exact app steps vary by marque and market, and a code for the original radio may not work if the unit has been replaced.
Start with the handbook
Check the front and rear covers of your vehicle’s handbook. Renault UK says the radio code is printed there; Dacia says it may be inside the handbook or service book. If you find a code card or entry, try that code before requesting another.

Get a Renault radio code for free
Use the My Renault app
- Sign in to your My Renault account or create one, then add your vehicle if it is not already listed.
- Open Vehicle details, scroll to Radio Code, and select Reveal Radio Code.
Renault UK lists this app method as free. If you need to add the vehicle, Renault says you can use its VIN; the 17-character VIN is on the V5/vehicle registration document or at the base of the windscreen. Do not post your VIN publicly.
If the app route does not work
Renault UK’s official shop offers a code request using the vehicle registration or VIN and proof of ownership. Its FAQ lists the request at £10; this is a UK-specific price, so check the current terms before ordering. See the Renault UK radio codes page and Renault UK FAQ.

Get a Dacia radio code for free
Use the My Dacia app
- Sign in to My Dacia. If you do not have an account, download the app, create an account, and add your vehicle.
- Open My Vehicle, select Vehicle information, then scroll down to find the code.
These steps are from Dacia Ireland. Its FAQ says the code is accessible through the app on a smartphone or tablet, so availability and labels may differ in other markets. See the Dacia Ireland FAQ.
What to do if the code is rejected
Dacia advises that a code may fail if the radio or media unit has been changed. Contact a local dealer to check whether the installed unit is the original one and to confirm the right next step. A code associated with the vehicle may not match a replacement radio.

The manufacturer sources above describe handbook, app, and official support routes; they do not validate third-party code-generator sites. Use the manufacturer’s account or support channel instead, and do not remove the radio just to look for a code before trying the documented options.
