dacia and renault radio codes

March 21, 2026

If your Dacia or Renault has lost power or had its battery disconnected, you might find your radio asking for an unlock code. Instead of paying a dealership to unlock it, you can find the code yourself using our lookup tool below.

How to find your pre-code

1. Remove the Radio: You will usually need radio removal keys (or sometimes just a couple of small screwdrivers or pens) to gently pull the unit out of the dashboard.
2. Find the Sticker: On the back or side of the radio, there will be a sticker with various barcodes and serial numbers.
3. Identify the Pre-Code: Look for a long serial number. The “pre-code” is always the last four characters of this serial number. It consists of one letter followed by three numbers (for example, A123 or V482). Sometimes it is written separately, often prefixed by “T0” (e.g., T0A123).
