Radio Code for Renault

After the battery is disconnected or the radio is replaced, a Renault radio asks for a 4-digit code before it will play. This app calculates that code from the radio's pre-code, right on your phone.

This is an independent app. It is not made by, affiliated with or endorsed by Renault. Renault is a trademark of its owner, used here only to describe compatible radios.

WHAT YOU NEED
The pre-code: 1 letter + 3 digits, printed on a label on the radio's case. Example: B382.

HOW IT WORKS
1. Take out the radio and read the pre-code on the label.
2. Enter the pre-code in the app.
3. Enter the 4-digit radio code on the radio.

WHERE TO FIND THE PRE-CODE
Many Renault radios come out with a pair of U-shaped release keys, pushed into the slots on each side. Others are held by screws. Look at the labels on the top or side of the case for the 4 characters that start with a letter:
- B382-SECURITY: enter B382
- T0A609: ignore T0 and enter A609

HOW TO ENTER THE CODE
The app explains each method with pictures. Switch on the ignition and the radio first.
- Preset buttons: buttons 1 to 4 set the digits, then hold button 6 (or 5) for about 10 seconds to store the code.
- Steering wheel remote: press the confirm button, then turn the thumb wheel for each digit.
- Stalk control with a CD radio: the thumb wheel changes the digit and the bottom button moves to the next one.

IF THE CODE IS WRONG
Check every digit before you confirm. Each wrong code locks the radio for longer: 1 minute, then 2, then 4, doubling up to 32 minutes.

GOOD TO KNOW
- The calculation works only from a pre-code in this format. Older vehicles may have no pre-code on the label.
- The calculation runs on your phone and needs no account.
- Available in English, Spanish, French, Portuguese, German, Russian, Italian, Turkish, Polish and Hungarian.

Use this app only on a radio you own or have permission to unlock.
