Renault radio unlock code generator online directly on the Dustershop77 website:
| Generate unlock code: The PRE code looks like (543=0543 or 43=0043) |
So, after disconnecting the battery, you have a problem - the radio does not turn on, you need to enter a code.
This code may be written down in your service book that came with the car, but if it is not there, then you can
1. Get it from the Dealer
2. Generate with a special program (link to the program)
We will not consider the option of obtaining a code from the Dealer, but will consider obtaining the code independently through the RENAULT PRE-CODE CALCULATOR program.
In order to receive the code, you need to install the RENAULT PRE-CODE CALCULATOR program and run it, after launching you need to enter PRE-CODE, based on which the program will issue a digital 4-digit unlock code, which is used to revive the radio.
To find out PRE-CODE:
— with the radio turned on, simultaneously press buttons “1” and “6” for 3-5 seconds
— the message “pre code xxxx” appears on the display; it contains one letter and three numbers
- this is the PRE code of your radio
If your buttons do not work, or for some reason the radio does not display the pre code value on the screen, then you need to remove the radio and find the pre-code on its case.
The code is circled in red, contains one letter and three numbers, write it down
— enter the pre-code into the RENAULT PRE-CODE CALCULATOR program window
The program will respond with Code = XXXX, where XXXX is the 4-digit unlock code for your radio.

We check the documents.
At the factory, each radio is assigned a specific lock code. As planned, this allows you to protect the device from theft, since without it it is impossible to use the device. In practice, all car owners who have at least once accidentally discharged the battery or turned it off during repairs face this situation. To find out, you can look at the vehicle documentation. The required 4-digit combination will be written there, with which you can activate the Renault Duster radio.
Reasons for blocking
Which video topics interest you
The basis for all the reasons for blocking the factory player on Renault Duster is a short-term or long-term lack of voltage in the power circuit. If a malfunction is detected, standard equipment automatically turns on code protection.
Alternative players installed by the user or at the dealership are not equipped with a lock. After restoration of functionality, it is necessary to configure the equipment, including programming the clock. In this case, the frequencies of radio stations are stored in the memory of the audio device.
Battery disconnection
The battery terminal is disconnected when replacing a device that has expired or has a damaged housing. Also, removing the terminal is required to perform repair work on the body that involves the use of welding.
After the battery is disconnected, a protective algorithm located in the firmware of the Renault Duster radio is triggered, blocking the equipment.
Electrical short circuit
In the event of a short circuit or overload, a fuse located in a separate block is triggered. An interruption in the voltage supply is perceived by the head unit as an attacker disconnecting the plug.
The underlying algorithm automatically activates the car radio lock when the power supply is restored.
Battery discharge
Another reason for blocking the head unit is a voltage drop in the on-board network that occurs when the battery naturally discharges.
When the threshold value set in the algorithm is reached, the audio player controller sends a signal indicating a power failure, which causes the blocking to turn on. The problem can occur in winter after unsuccessful restarts of the engine, which lead to battery discharge.
Search PRE-CODE.
But, if you are the owner of a used car and the documentation for it has already been partially lost, then the situation becomes a little more complicated, but still solvable. First you need to get the PRE-Code of the radio, you can do this in one of the following ways:
Press buttons 1 and 6 for 3-5 seconds, after which the message “pre code xxxx” will appear on the screen. It has an alphanumeric form, for example, "D657". On older models it may
consist of only 3 digits.
If the combination of buttons on the radio does not work, you need to remove it and find the pre-code on the sticker on the back.
or like this:
Or this:
In the following example, you can make a mistake by entering 0 into the generator instead of the letter O. You need to remember that if the pre-code consists of 4 characters, then the first one is always a letter, the remaining 3 are numbers.
In some cases, the code may even consist of 2 digits. The code generator requires 4, so you need to substitute zeros for the existing 2-3 digits.
In order to enter the code for the Renault Logan or Duster radio, you need to use the keys on the device panel, then hold down button 6 for a few seconds. If the code is correct, the lock will be removed. Otherwise, an error message will appear on the device.
How to install
On basic modifications of the car, only audio preparation is provided; further installation of the radio is carried out by the dealer or owner. To perform installation work, you will need a screwdriver with a Torx T-30 head, a mounting spatula or a plastic card and a set of adapters necessary for switching.
Brief instructions for installing equipment:
- Pry up the clips and take out the shelf for small items located in the regular place of the radio.
- There are ISO connector plugs attached to the back of the element that need to be removed.
- Place adapter elements on the connectors; it is recommended to protect the connection points with a layer of insulating tape. Additionally, you should check the compliance of the cables on the radio and in the standard wiring harness of the car.
- Place a metal mounting basket in the instrument panel, which is secured by bending the triangular plates around the perimeter.
- Connect the plugs to the head unit, which is then installed in the mounting window.
- Mount the decorative frame around the front panel.
Additionally, it is required to install loudspeakers in standard windows in the doors. The landing nests are covered on top with decorative plastic grilles. Inside there is a wiring harness equipped with a plug. Since alternative connectors are not compatible with the connector, either replacement of the connecting elements or removal of the plug is required. The cut wires are connected by twisting or crimping with a brass tube.
Differences between Renault radios.
Even cars of the same model can have different media devices installed. Therefore, it is not surprising that activation methods may differ slightly. Let's consider each model separately:
RENAULT Philips 22 DC 459/62E. This model does not have a display. After switching on, the inscription CODE will appear on the auto panel. You will have to enter a combination of numbers using the steering column joystick. To do this, there is a cylindrical switch C on the rear. The B key allows you to move to the next position. After entering the code, the radio is activated by pressing the “B” key again.
RENAULT 22 DC 279/62Z CD Philips. This model also does not have its own display. The original remote control is used to enter numbers.

Unlocking the car radio using the example of a Ford Focus 2 car
Ford Focus 2 is one of the most common cars in Russia. That is why we will look at unlocking the radio using the example of the music system of this car.
We recommend: Removing and replacing the ignition switch on a Renault Logan (photo and video material)
When you see an inscription on the display that requires you to enter a code, try to find it in the instructions. If your radio is standard (came with the car), a sticker with the required alphanumeric combination may be on the glove compartment. With its help you can easily unlock the radio.
Attention! Sometimes dealers themselves write the code on the first or last page of the service book.
If you find the code, unlocking the radio will not be difficult, however, the exact opposite situation is also possible. The instructions may get lost among many similar manuals, and no one will write the much-needed numbers in the service book. There's no need to talk about the glove compartment.
Fortunately, there is a universal algorithm that will help you unlock your radio in a few minutes. To do this you need to perform the following set of actions:
- Press buttons 1 and 6.
- The display will show a variety of information.
- Wait for the data to pass through.
- There will be a code at the end of the line.
There is another option. You can dismantle the radio and unlock it using a code, which is often indicated on the sticker of the device. There are only a few cases where these measures will be useless.
In the first option, you simply exceeded the limit of attempts to enter the code, and the device was permanently blocked. In this case, you will not be able to unlock it using the correct code.
Some Ford Focus 2 cars had special radios installed; to unlock them, you need special software. To receive the code, you need to enter the device serial number into the program interface, and the unlocking will take place.
How to dismantle the radio
To unlock the radio of a Ford Focus 2 car, you need to dismantle it. But this must be done extremely carefully so as not to damage the device or damage the wiring.
To dismantle and subsequently unlock the radio, you will need special keys. Usually they come included with the device. If necessary, they can be purchased at a car store for a very reasonable price. If you don't want to spend money, there is an easier way to unlock the radio - just take a utility knife.
Attention! When using a knife, be careful not to press too hard on the handle, as there is a risk of seriously damaging the panel.
It’s better not to risk it and make a key to remove the radio from a simple plastic card. True, this will take a little longer, but such a precaution will allow you to unlock the device in the future without any problems. The key creation process consists of the following steps:
- Take a card and use a pen to draw three stripes evenly spaced from each other.
- Take a knife and cut the card along the marked lines.
- Grind down one corner of each plate.
After you create the keys that will help unlock the radio, you will need to insert them into the symmetrical holes located along the edges of the device. Slowly swing the keys, trying to remove the clamps and temporarily dismantle the car radio.
Important! This dismantling scheme only works on the SONY 6000 radio.
Other types of radio tape recorders are even easier to dismantle. More precisely, this is the same SONY 6000 model, but of a different modification. The main difference is the shape. The stationary version is made in the shape of a square, the other two are an oval and a restyled version.
These modifications are fixed by means of a casing and bolts. The dismantling process consists of the following stages:
- Use a ruler to pry up the casing and remove it. Underneath you will find 4 bolts. They have characteristic hexagonal caps.
- Use a screwdriver to unscrew the bolts.
- The device is removed.
The code is located in the standard place. With it you can easily unlock the radio
In very rare cases, the code on the device body may be erased or absent altogether. In this situation, all you have to do is contact the dealer. There is absolutely no need to go to the service center. All you have to do is call the phone and provide the details of the radio that needs to be unlocked. The series and number will be enough to get the password.
How to enter the code
After the code is carefully written down on a piece of paper, it’s time to unlock the radio, and here many drivers have a lot of questions. One of the most common: how to enter numbers? It's actually quite simple. For input, use the keys responsible for selecting radio frequencies.
We recommend: Renault Logan throttle body cleaning procedure
The general algorithm for entering the password required to unlock the radio is as follows:
- First, a request message will appear on the display.
- The next step is to enter the code using the buttons.
- The display has only four positions, so be extremely careful when entering. After each cell is filled, the process will proceed in the second circle.
- At the end of the combination, press *.
During the unlocking process, you must remember that the password can only be entered 10 times. After this, the device will be securely locked. Each time before entering, the number of remaining attempts will be displayed on the screen.
Attention! In most models, the failed attempt counter resets every half hour. Therefore, you will still have a chance to try to find the right combination.
Cracking the code
If all the methods described above did not give the desired result, you will have to unlock the radio by hacking the code. It all starts with dismantling the music system. Naturally, each machine has its own mounting structure for the device. Therefore, before starting dismantling, it is better to read the instructions.
Once the device is removed, read the serial number. In this case, the wires do not need to be disconnected. The next step is to select the appropriate program that will help unlock the radio.
Enter the device information in the window and wait for the system to generate a password. This usually takes no more than a few seconds. Enter the code, then insert the radio back.
