A Dacia Duster radio asks for its security code after the head unit loses its permanent live feed — a flat battery, a battery change, a jump start or the radio being unplugged. The code is held against the serial number of that head unit, not against the registration or VIN. Fitted units: Dacia Plug&Radio, Renault-derived CD units, Media Nav. Ignition on, radio off, hold button 6 for several seconds to see if the pre-code displays. Once you have the serial, enter it in the radio code finder on this page.
Radio codes belong to the head unit serial number, not the vehicle registration or VIN.
A flat battery, battery replacement or radio removal is what triggers the code prompt.

How to find the serial number:
Ignition on, radio off, hold button 6 for several seconds to see if the pre-code displays.
If not, remove the unit with two extraction keys.
Read the PRE-CODE line — a letter plus three digits.
Take a photo of the label before refitting so you never have to do this twice.
How to key the code in:
Presets 1 to 4 select the digits.
Hold button 6 to confirm.
Stop and re-check if the first two attempts fail.
Worth knowing:
Base and Essential trims: simple Plug&Radio or CD units that use the Renault pre-code system and will ask for a code after a battery disconnection.
Media Nav trims: touchscreen units that generally do not prompt for a four-digit radio code.
Duster fascia panels are chunky plastic clipped in place — start at the outer edge and work in, ideally with a plastic trim tool rather than a screwdriver.
Rural Dusters used seasonally are prime candidates for flat batteries; if this happens repeatedly, test the battery before blaming the radio.
My Duster has Media Nav — do I need a code? Usually not. Media Nav systems typically restore without a four-digit audio code after a battery disconnection.
Which extraction keys fit a Duster? The Renault-style U-shaped keys, not the flat Ford type.
Is the code in the handbook? Often yes — Dacia dealers frequently supplied a code card in the handbook wallet when the car was new.
