Surely, almost all owners of French-made cars have encountered a problem when an inscription about the need to enter an unlock code lights up on the screen of the standard car radio. Let's look at how to unlock the standard Renault radio and what steps need to be taken to solve this problem on various Renault cars.
How to unlock on Renault?
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.
What is a PRE-CODE and where can I find it?
The precode is necessary to obtain the unlock code, apparently the manufacturers thought that this was a sufficient measure against radio thieves, but for now it is an excellent measure to blow the brains of the owner. As always, not on time. So we are looking for precode.
In the photo there are possible options for finding the precode on stickers:
Look carefully for the analogy, the code is definitely there.
Renault Megane 2
As already indicated, car radio coding is used to prevent its use after a power outage, which can happen when disconnecting the battery terminal, removing the radio, or replacing the fuse. The decoding code can be found at the service center, can be indicated in the radio's passport, or obtained using a generator program.
In order to unlock the radio on Renault Megane 2, you need to turn on the ignition and the car radio. The words “CODE” and “0000” will appear on the screen, the leftmost number “0” will be blinking. Use the buttons for tuning stations from 1 to 0 to enter the unlock code. The numbers you enter will not be visible on the screen. After the number in the first field is entered correctly, the icon for the second field begins to blink, and so on until the end. If the code is entered correctly, the car radio returns to normal operation.
When entering the code you must be careful, because... with two consecutive incorrect entries, the “CODE” inscription lights up and flashes; the third error will cause the “CODE PAUSE” inscription to be displayed, and repeated entry can only be made after 15 minutes.
A similar sequence of actions is performed when unlocking the Renault Simbol, Renault Laguna 2 car radio.
Unlock methods

The most common methods for unlocking car radios are:
p, blockquote 16,0,0,0,0 –>
- code calculation using special equipment;
- dismantling the memory chip, reading the code on the programmer;
- definition (code generation) using special software;
- obtaining a PIN code from the dealer.
To unlock the radio using the first two methods, special skills and equipment are required. To obtain information from a dealer, it is necessary to create an official request at a dealer or specialized service station. Receiving an answer will take at least two to three weeks if the car is operated far from large cities.
Renault Duster authentication key
For the time being, any owner of a Renault Duster car from France does not need to work with the radio code. The hour X strikes when, for certain reasons, the driver needs to remove the terminals from the battery. After such a manipulation as removing the terminals in the car, a complete reset of all systems without exception occurs to the factory settings, and if you try to turn on the ignition, then the car radio will ask you to enter a special audio system code. Without its input, the system will never work.
At the same time, the owner of the car immediately has a question, which is quite natural: why is such an inconvenient measure used for the driver of a Renault Duster? The answer is clear as day: the manufacturing company has made sure that no hijackers or thieves even try to steal expensive electronics in order to profit from it. Until the radio code is entered, it is a piece of plastic and metal, and, of course, will not be able to properly perform its direct functions.
To enter an authentication key, you just need to type a few keys, and this process takes a couple of minutes.
The process of removing the standard radio for Renault Logan 2 and Sandero 2
To remove the radio on the new Renault Logan, you need to remove the decorative plastic trim.
If you do not have special pullers, then using a flat screwdriver and a soft cloth, pry up the edge of the edging and gradually snap it off. The photo of the removed edging will be below; pay attention to the location of the plastic clips.

Next, remove the outer panel to get to Logan's radio. It is quite difficult to remove from the clamps; you will have to help with pullers or a screwdriver wrapped in a cloth.

For reference, the rear speakers are 13cm.
The back of the radio, the 4 underlined characters (1 letter and 3 numbers) are the pre-code of your radio, by which you can find out the code from it.

Lada Largus radio code generator
To obtain the Lada Largus radio code, special generators are used. This is either an online service or a desktop application.
All this password protection for the radio was invented in order to minimize theft of head units. The Lada Largus radio is completely unified with the Renault and Nissan radios. Using the radio code prevents thieves from accessing multimedia functions, making stealing the radio useless. At least that's what the creators of this function thought, but in current realities it doesn't make any sense. After all, if there is a back label of the radio with a PRE code, generating a password for the radio is not difficult.
Renault Logan security code - look for it on the radio body
You can find the code to unlock the radio on the case. It can be written as part of a cipher or as a separate code. The photo shows options for placing the car radio code on the case for standard versions 2013, 2014, 2015, 2016, 2022. New bodies are equipped with more advanced versions of media systems, including basic car radios from new manufacturers. As a result, labeling may vary significantly.
At the same time, the car may someday, at the most inconvenient moment, ask you to dial this code. Unlocking will be difficult if you are not armed with the necessary knowledge. Look at the photo for location options for Renault Logan 2013, 2014, 2015, 2016, 2022.
Car radio code
So, the required cipher is a four-digit combination of one letter and three numbers. It must be entered after the battery has been disconnected and the media system needs to be unlocked. Obtaining it from the case is not the only way to restore the missing number combination. On 2013, 2014, 2015, 2016, 2017 models this can be done using the device function without the need for disassembly.
Reading the chip
Decoding the radio using an alternative method will require the basic skills of a radio engineer and additional equipment:
- soldering iron, rosin, flux for desoldering. It is most convenient to use special clothespins for microcircuits;
- programmer (universal or homemade);
- special software for reading memory dumps.
To decode you need:
- remove the cover of the car radio, if necessary, the CD drive;
- find the memory chip. Usually it is small in size, with 8 “legs”. The photo shows a radio tape recorder with a Honda CR-V;
- The circuit can be unsoldered and connected to the programmer. To work with BR9010, you can use UPA USB Programmer. As you can see in the video, you can actually assemble something like a programmer with your own hands from improvised means. The Chameleon programmer can be used as reading software. It is important that the device supports operation with the type of microcircuit that is installed in the radio;
- reading memory dump. Among the received data, you need to find a four-digit number. This may take time as the manufacturer tries to protect the code.
Don't be alarmed if your first entry attempt is unsuccessful. The combination in memory can be written in reverse order. To check, it is not necessary to solder the circuit back. You just need to connect power to the car radio. The player will operate normally, but without a memory function (for example, the selected radio station).

More ways to unblock
Let's look at how else you can find out the code for the Renault Duster radio:
- Contact your dealership for information - to do this you will need to send an official request. You should expect a response within 2-3 weeks.
- Calculating code using specialized equipment - accordingly, it is necessary to find workers employed in this area.
- Removing a memory chip and then reading information requires experience in such work.

After disconnecting the battery
When the battery terminals are removed, the power on bus 30 is completely lost. The standard radio is permanently connected to it for storing memory data (settings, settings, channels), including identification ones.
p, blockquote 7,0,0,0,0 –>
If such a disconnection of the battery terminals is short-term, it is possible that the power supply to the memory chip will be supported for some time by a large-capacity electrolytic capacitor installed in the radio.
p, blockquote 8,0,0,0,0 –>
In some cars (for example, Mercedes), an additional small-capacity auxiliary battery is installed in the on-board power supply system for this case. In such cars, it is largely intended for uninterrupted power supply to the on-board computer. Some car enthusiasts install an additional battery to avoid problems with the immobilizer and radio.

After a long-term disconnection of the battery terminals, the memory of the Renault Duster radio is reset, after which you need to enter the radio unlock code.
p, blockquote 10,0,1,0,0 –>
The developers provide such a procedure to increase security against the car being dismantled by hooligans and thieves. Typically, such a security measure has low effectiveness, since PIN code recovery or calculation can be done inexpensively in specialized workshops. In Renault Duster cars, this procedure can be performed independently.

Electrical short circuit
This situation can arise as a result of an accident, breakdown of rectifier diodes in the generator, during poor-quality repairs of electrical equipment, etc.

Significant battery discharge due to leaks in the vehicle's power supply circuits while parked
If such situations arise, when after a short stay (from 0.5 to 5 days) the car starts with difficulty, the on-board voltage drops to 9 volts or less, it is necessary to determine the location of the current leak and eliminate the problem. One of the likely places for current leakage is the car radio.
p, blockquote 13,0,0,0,0 –>
Full battery discharge during long-term parking
Typically this problem occurs when the car is parked in the winter. It is advisable in winter to periodically (once a week) start the car, warm it up and charge the battery with the engine running for at least half an hour. This measure is effective not only for eliminating problems with the radio, but also for extending the life of the battery and lubrication of engine components. When warming up, it is a good idea to drive the car a couple of meters forward and backward to prevent the brake pads from sticking.

Recommendations
p, blockquote 40,0,0,0,0 –>
- write down the generated correct code in pencil on the back panel of the car radio, in your notebook, or phone;
- Before carrying out work, flip through the service book; perhaps the previous owner has already entered the PIN code for unlocking the radio in it;
- try to keep the battery charged even when parking the car for a long time in winter.
For those car owners who have a Starline A93 alarm system installed, the operating instructions allow you to know and use all the functionality of this car security system.
In some cases, especially before purchasing, it is useful to check the car according to the state license. number or VIN code.

Unlocking standard Renault car radios
Pecode is usually located on the rear panel of the car radio. It consists of a Latin letter and a number. They should be looked for in the endings of serial numbers, long number combinations, and other incomprehensible characters. Most Renault car radios have information about the so-called Pre-Code on the rear panel. On the Internet you can find links to download the RENAULT PRE-CODE CALCULATOR program. For example: dustershop77.ru/kopilka-znanij/manualyi-instrukczii-i-rukovodstva/zablokirovalas-magnitola-kak-uznat-i-vvesti-kod-ot-magnitoly-reno!-otvet-zdes!-generator-koda!.html
If you receive a PRE code, it may turn out that the generator will provide not 4, but 3 or even 2 digits. If such a situation arises, zeros are simply added in front according to the number of missing digits.
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 can only consist of 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 this:
In this case D833
In this case the pre code is H635
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.
Why does a car radio need a pin code?
In the distant 80s (last century, if anyone remembers), good car radios cost a lot of money: the Chinese industry was not yet on the rise. But there was crime then too. The easiest way to make quick money was to steal a car radio. Until the 2000s, I had five cars in consecutive use, and the radios on all (!!!) cars were stolen.
Sometimes with breaking glass or a door window, sometimes with the help of ordinary scissors instead of a key. As a way to protect car radios from theft, manufacturers began to encode them. That is, after removing the radio from the car, disconnecting it from the on-board power supply, the next time it was turned on, it required entering the code set by the manufacturer.
It must be said that for the Russian craftsman this is not protection, but, on the contrary, a way to generate additional profit. Masters immediately appeared who, for a certain fee, spent an hour calculating the code using simple homemade electronic devices. The problem of car radio theft is still relevant today. As long as there is demand, they will steal, no matter how they are coded.
The fact is that the car radio may require entering a code without it being stolen. In which case?
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 find out the code
Before unlocking the radio on the Renault Duster, you need to determine the code. Cars purchased from an official dealer are accompanied by a set of documentation. The manufacturer informs the seller of the information, and he enters the password into the service book (in a special field located on the side of the cell for the VIN number) when selling the vehicle.
To determine the code, you can use a special preliminary code (written under the serial number of the part and duplicated in the serial number), which will need to be entered into the online calculator. The information is not printed on a paper label glued to the outside of the player’s body (together with the technical parameters and serial number of the product). To view the value, you will need to remove the audio head unit from the instrument panel.
To remove the product, you will need to remove the decorative trim on the central part of the instrument panel, and then unscrew the Torx screws (size T20) that hold the housing of the multimedia device. There are additional control buttons on the frame; to facilitate dismantling, it is recommended to unfasten the patch cables from the connectors.
The found code is entered into the calculator, and at the output the owner receives a 4-digit digital code. Before programming, you need to reinstall the radio and decorative frame. When connecting cables, it is necessary to check the pinout and position of the plugs; incorrect connection leads to damage to the electrical circuits.
If the codes on the radio could not be found (the paper tag is damaged or torn), then it is possible to search for the code value using the VIN number, which is assigned to each car. To determine the value, you need to contact an official Renault dealer, who will generate and send a request to the manufacturer.
