Dacia Logan Radio Code by VIN Number or Security Code
If the radio in your Dacia Logan is asking for a code after a battery disconnect, a flat battery, an electrical repair or a unit replacement, you can request the unlock code online using your vehicle’s VIN number or the short security code printed on the radio label.
On most Dacia Logan vehicles the VIN starts with UU1, for example UU1LSDL0475019844. Some radios instead display a short security code, such as L523, which is used to identify the final unlock code.
Enter your Logan VIN or security code
Use the full chassis number or the code shown on the radio label.
Where to find the VIN or security code on a Dacia Logan
Dacia Logan audio systems are linked either to the vehicle’s own data or to a short code printed directly on the radio housing. If you have the car’s registration documents on hand, the fastest route is usually the VIN number, which for Dacia almost always starts with UU1.
Example of a Dacia VIN. On Logan models the series typically begins with UU1.

Check the VIN
Found on the registration document, near the windscreen, on the driver door frame, or on the manufacturer’s plate.
Check the radio label
If the unit has been removed from the dash, look for a sticker with a short code such as L523 or M812.
Enter the details correctly
Type the VIN or security code exactly as shown. A single wrong character can lead to an incorrect result.
Why does a Dacia Logan radio ask for a code?
Many factory audio units fitted to the Dacia Logan include an anti-theft protection system. When the car battery is disconnected or the radio loses power, the unit automatically requests the security code before it will work again.
This commonly happens after a flat battery, a battery replacement, a jump start, an electrical repair, dashboard work, or a radio swap. In most cases the unit itself is not faulty — it simply needs the correct code to reactivate.
Dacia is part of the Renault group, so many of its audio systems are closely related to Renault units. That’s why some radios show a pre-code on the label, while others can be identified directly from the vehicle’s VIN.
Dacia Logan radio code by VIN number
If you’d rather not remove the radio from the dashboard, the VIN number is often the simplest option. A Dacia Logan VIN normally starts with UU1, followed by a mix of letters and digits. Example: UU1LSDL0475019844.
You can find the VIN on the vehicle’s documents, in the lower corner of the windscreen, inside the driver door area, or on the vehicle identification plate. Always enter the full VIN, not just part of it.
Once the VIN or security code has been verified, the matching radio code is checked and sent to you by email — a much faster alternative to booking a dealer visit just to get the radio working again.
Many Dacia vehicles share the same audio units as Renault models. If your car uses a Renault-style security code or VIN, visit our Renault Radio Code page for more information and code retrieval options.
Common Dacia Logan security code examples
Some Dacia Logan radios display a short security code printed on the unit’s label. This is not the final unlock code — it’s used to identify the correct code for your specific radio.

M812
Common pre-code format shared with some Renault units.

Another example of a short radio security code.
Once you receive your code, it must be entered correctly using the preset buttons on the radio. Many Dacia models, including Logan, Duster, Sandero and Dokker, use a similar procedure. This short Renault Dokker demonstration shows how the code is entered and confirmed on a compatible factory unit.
