How to unlock the radio in a Mercedes; Repair and service

Easy way

If the car is fairly new, especially under warranty, and you don’t have an hour of free time and the desire to save a couple of thousand, you can put the problem on the shoulders of servicemen. It will be a great success if the employees of the dealership agree to provide assistance for free (usually the price starts from 2,500 rubles). Before you find out the radio code, you will need to tell the specialists the serial number of the player (where it is located and what it looks like - we’ll look at it later).

It is likely that the former owner of your car also wondered how to unlock the radio. Having his contact information will be a real salvation for you in this case. Since the code is unchangeable information, to prevent repetition of an unpleasant situation, car owners often write it down with a marker or stick a sticker on the body of the radio. In any case, if the previous methods did not help you, the device will have to be removed from the panel.

Serial number

How to decode a car radio:

• remove the player from its standard seat. It is held on by special latches that need to be pushed aside by inserting a long, flat object (like a woman's nail file) into the cavity between the radio and the instrument panel. Detailed information on extraction can be found in the repair and operating manual for your car model;
• Find the marking sticker on the case on which you have applied the barcode, as well as other identification numbers. You need a combination of letters and numbers after the Serial No. – this will be the serial number;
• Next, on the Internet you need to find a service that, using Serial No., generates an unlock code. For example, https://www.radio-code.lt/. In the left corner there is a catalog of car brands. After this, you need to select the player type. You will receive a list of models from which you need to select your car radio. The convenience of this resource is that most types of devices are photographed. After clicking on the “View as gallery” tab, the list will be displayed in the form of pictures. Selecting a model will redirect you to a page with a field for entering the serial number (“Enter serial number”). All you have to do is enter the data and click “Search”. Radio-code.lt is not the only one of its kind, so you can use another code calculator. Most resources of this type will require you to follow a standard registration process before decoding your radio.

Never send SMS when creating an account. Most likely this is a scam site. Therefore, it is not a fact that after withdrawing funds you will be able to decode the player.

Entering the code

When typing a combination, be careful, as the number of attempts is limited. In some cases, to activate the code entry mode, you need to hold down two specific keys. The number is dialed using the radio station selection keys. Pressing the button once adds one to the corresponding number on the display. Sometimes after entering you need to press an additional button (for example, SC on Mercedes).

PRE-Code

Many Renault owners do not need to remove the player from the panel before unlocking the car radio. Standard devices are marked with a special Security code (a four-digit code with a first letter and three numbers). After turning on, hold down keys 1 and 6 for a few seconds. If “PRE-Code-ХХХХ” does not appear on the screen, the car radio will still have to be removed.

Unlocking is carried out using a code generated by a special script. To calculate, you can use an online resource or a special DOS program.

• Entering the PRE code.
• The program generates a four-digit number, which will be the code for self-unlocking (4702).
• After dialing, press and hold button 6 until the decoded device emits a characteristic signal.

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.

After manually entering the code inside the car radio, identification occurs. Of course, for this to happen, the correct set of characters must be “hardwired” inside the device. The essence of the method is to solder to a non-volatile microcircuit on which the code is written and read the information.

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).

Thank you very much, I was looking for such a program for a very long time. If you have it, you can also send it to other radios.

Decoding the car radio by serial number

If you have the Internet at hand, you can unlock the audio device yourself. The action plan is described below.

Removing the radio

Correct decoding of a car radio by serial number begins with removing it from its original location. Most often, it is fixed with special latches: to move them away, insert a thin, long flat-head screwdriver between the body of the product and the dashboard. If something doesn’t work out, don’t use force - it’s better to read the instructions for the radio: it should indicate how to install and remove the device.

Removing the radio from its original location

Where is the serial number located?

Look for a barcode sticker on the case where identification numbers will be printed. You will need the one after the Serial No. The sticker is most often located on the top, less often the back, of the product.

Radio serial number for Ford

Radio unlock code calculators

Go to the Internet and find a service that can unlock it using the serial number of the car radio. For example, https://www.radio-code.lt/. Here in the upper left corner is a catalog of car brands. Find yours and select the type of radio (if necessary, use a photo, which is very convenient on this service). Next, you will be redirected to a page where you need to enter the serial number. Select a radio unlock code calculator using the Search button, for example, it could be Radio-code.lt or some other.

Before decoding, the service will ask you to register. The procedure is free. If suddenly they start asking you to send SMS, most likely you have visited a fraudulent web resource.

Having received a combination of characters, type it: be careful, because the number of attempts is limited. Usually it is suggested to alternately press several keys: selecting radio stations or others. One press adds one to the number on the screen.

Unlocking the Audi car radio

So: there was a power outage to the radio + the promising inscription “SAVE” is displayed on the screen + the device does not respond to key presses, the question is - what to do? First, you need to remove the radio.

Removing the car radio

To dismantle the car radio, you need to use special pullers, which we will use to press out the fastening latches of the device (pictured).

Pullers for dismantling Audi car radio

Well, since these auxiliary “devices” can only be found from “officials,” I suggest making these simple devices with your own hands:

Homemade Audi car radio remover

Next, install the left and right puller into the holes on the head unit...

Audi car radio code calculator

...at this time you should feel a click, which means that the locking latch has been pushed back and the puller is locked in the groove. We take out the car radio, pulling the device towards you.

Advice! When dismantling double-din car radios, as a rule, four pullers are required, but you can do it with two if you perform the above operation for each side in turn.

Unlock code

The unlock code number and identification number of the car radio are initially indicated on the first page of the user manual, under the contents. This place with a code number is called a radio card, it must be stored in a safe place (not in the car!). If this information is missing, then download the program “audi car radio code calculator” (https://rusfolder.com/26809933) and run it...

Audi car radio code calculator

...enter the radio identification number indicated on the rear panel...

Audi car radio identification number

...we receive the generated four-digit unlock code and register it in the car radio.

Unlocking the car radio

With the car radio turned on with the inscription “SAFE” displayed on the display, depending on the model, we perform the following actions:

Models "Beta", "Gamma" and "Delta"

• By holding the “DX” and “F1/2” keys for a long time, we activate the operation of entering the unlock code;
• Alternately, using the keys “1”, “2”, “3” and “4” we enter each of the digits of the code;
• We confirm the end of entering the cipher by pressing the “DX” and “F1/2” keys for three seconds.

Example of entering a code for Toyota

Radio tape recorders for cars of this brand use a 3-digit code. Turn on the device and wait for Security to appear on the display. Then press the top arrow and, while holding the button, dial one. Another word should appear - Code. Now enter the correct code by pressing numbers from 1 to 3. To confirm, press T1. If everything went well, Security will appear on the screen again and the radio will turn off. Turn it on and use it!

For Ford

The input method is suitable for most models. Turn on the car radio and wait until a mark appears prompting you to enter a code. Indirect method: press one and wait for the first digit to appear. Further input is made using buttons 2 to 4. At the final stage, the “5” key confirms the code.

For Nissan Note

As an example, we can consider entering code 5475. To enter the first digit, press the “1” key 5 times, then press the “2” button 4 times, press the “3” key 7 times and press the “4” button 5 times once. If the received code contains “0”, you do not need to enter it.

Entering a code in the radio for Nissan

For Audi (Symphony, Concept Plus models)

Check your vehicle's owner's manual. The serial number of the car radio and the unlock code are indicated on the 1st page, below the contents. Store the data in a place protected from prying eyes. If there is no information, use the code search using one of the methods described in the article. Once you receive the code, enter it:

• turn on the audio system, on the display of which you will see the word SAFE;
• press and hold the RDS, TP button at the same time and make sure that the number 1000 appears on the screen;
• enter the code numbers by pressing keys 1 to 4;
• Confirm the correctness of the entry by pressing RDS, TP, holding the keys for 3 seconds: the radio will turn off, turn it on and use it.

For models Delta, Beta, Gamma, the algorithm of actions is slightly different. To unlock the car radio, press and hold the F1/2 and DX buttons. The resulting code must be entered by alternately pressing buttons 1 to 4. To confirm the code, press F1/2 and DX again with a three-second hold.

For VW

Here, as in the case of Audi, you need to look at the first page of the car’s instructions. On it you will find the radio identification number and PIN code. If the device has touch controls, you need to enter the code numbers by pressing the monitor buttons. If the device is normal, press the buttons for fixed radio stations. When the code appears on the display, confirm it by pressing OK or Enter. If entered incorrectly, the radio will be temporarily blocked. To try again, leave the device alone for 2 hours. Then you can enter the code again.

How to properly remove a Mercedes Actros radio

Sometimes it becomes necessary to dismantle an old radio in order to install a more modern one with more functions.

This is done as follows:

1. First of all, you need to turn off the engine. To ensure safety, all work must be carried out only with the machine not running; 2. Next, the negative cable is disconnected from the radio battery;
2. Then the two fixing fasteners are disconnected. This is done with special keys, traditionally C-shaped. They are inserted into the designated holes until they click, which indicates that engagement has occurred;
3. Next, pull both keys at the same time and remove the radio. Remove the device carefully and slowly, using the keys as handles; 5. Then you need to disconnect the electrical wiring that goes into the device with a connector. Before doing this, just in case, you need to remember its location; 6. The antenna cable should also be disconnected;
4. Finally, you need to press the latches to completely remove the radio.

Place for a radio in a car
The Mercedes company supplies some radios with metal slides. Before removing the device, you need to make sure that this model does not have them. If there are still slides, you first need to bend the clamps on which they are attached.

Using PRE-CODE

In some cases, you will not need to remove the car radio from its socket. This applies to Renault owners. In cars of this brand, all audio devices have a Security code, which is a 4-digit combination of a letter and 3 numbers. After turning on the device for a couple of seconds, simultaneously press keys 1 and 6. If the display does not display Pre-Code-XXXX, you will have to pull out the radio to read the necessary information on its back wall (as shown in the photo below).

To unlock the code you will need a special script. The calculation can be made through an online service or a DOS program.

• enter the letter and numbers found on the back wall of the radio (PRE-Code);
• the program or online resource will generate a 4-digit number, which will become a code number;
• dial it and hold button 6 until the radio makes a characteristic squeak, sound, etc.

Reading the chip

This alternative method requires practical experience in the radio engineering field, as well as special equipment:

• a soldering iron with solder and (preferably) “clothespins” to help solder the microcircuits;
• programmer (can be homemade);
• a computer program that allows you to read memory dumps.

When its “native” code is entered into the car radio, identification is carried out. The correct set of characters is “hardwired” into the device. The problem that needs to be solved is to solder a code to a non-volatile chip in order to read it.

• remove the player cover, and if necessary, the CD drive mechanism;
• find a memory chip, which most often has 8 pins (as an example in the photo, a radio from Honda);
• unsolder the chip and connect it to the programmer: you can read the code using the Chameleon software or something similar (the software needs to be “skillful” in working with this chip);
• Find a 4-digit number in the information received.

You will have to spend time searching: the manufacturer is trying to protect the data. If after entering the result is negative, do not despair: try entering the numbers in reverse order. When testing, there is no need to solder the part back: just connect the radio to the on-board network. The device will work, but without remembering, for example, the frequencies of radio stations.

Proven ways to unlock a car radio

The idea to assign encoding to car radios (AM) came to the developers as a result of the fact that for many years car owners suffered from the problem of theft of media devices. Installing a code reduces the likelihood of selling a stolen car radio.

How to unlock an Audi car radio: advice from professionals

Code calculator for Audi car radios

This article tells you how to unlock an Audi car radio. Standard car radios installed in cars of this brand are specially encoded to protect them from hacking and theft. This encoding means that when the car radio is disconnected from the power source for ten to fifteen minutes, the radio is blocked and requires you to enter an unlock code to remove the protection.

Attention! In addition to blocking the car radio when the power is turned off, there is a second degree of protection that blocks the radio if the decoding code option is entered incorrectly three times. This blocking makes theft of an Audi car radio simply impractical.

In what situations does the radio become blocked?

How to decode a car radio by serial number or VIN code? First, let's figure out in what cases this need arises. Since modern audio systems began to be equipped with a special combination to remove the blocking, over time, vehicle owners were faced with a new problem. In particular, after dismantling the head unit or disconnecting it from the on-board network, the system is automatically blocked when the power is reconnected. Accordingly, many car owners now have to charge the battery in their cars without dismantling the AM.

Of course, no car is immune from cases associated with a break in the wiring that goes from the battery to the AM, or with a malfunction of the battery itself. During repairs, battery replacement or other manipulations related to wiring repairs, the AM will be automatically blocked, making its further operation impossible. If you are using a standard head unit that was installed at the factory, in order to unlock the system using the Wincode, you will need to find out the radio code. If you do not know how to find out the code, then refer to the service manual. Finding a way out will be more difficult if you don’t know the radio code; this is a common problem for car owners who purchased the vehicle secondhand (video author: Roman Samokhov).

Situations in which the radio is blocked

Along with the positive effect achieved through radio coding, a new problem has come to the automotive industry. Since each car audio system has its own unlock code, which is reset from memory when the power is turned off, a problem has arisen with battery repair and diagnostics. After removing the battery from the car, after a maximum of 10 minutes the radio will lock if it does not receive power again. In this regard, many car enthusiasts began to charge the battery without removing the terminals, so as not to block the audio system.

At the same time, no one is immune from the event of an open circuit leading from the battery to the radio or a malfunction of the battery itself. In such a scenario, there may not be a spare battery at hand, and the radio will be blocked. It’s good if you are the first owner of the car and have the opportunity to look at the unlock code for the radio in the service book, but if the car is bought second-hand, it will be more difficult to unlock the audio system.

Ways to find out the PIN code from the audio system

If you encounter a similar problem, you can try to unlock the car radio yourself. There are several ways to do this, all of which are detailed below.

Contact Dealer

If you do not know how to decode the radio, then first of all you can try to contact the dealer or seller. But keep in mind that if you contact an official representative of the automaker, then most likely they will not tell you the code just like that, and if they do, then most likely you will have to pay for it. On average in Russia this service costs about 3 thousand rubles.

Independent search

How to unlock the radio if you don't want to pay the dealer? Try to dismantle the head unit and find out its serial number, which is usually indicated on the system case. To do this, you need to pull the AM towards you a little, but do not remove it completely or disconnect it - this will simplify further installation (the author of the video is the BORODA CHANNEL channel).

Separately write down all the information you need, including the model of the head unit, as well as its brand. Next, using this data, you will need a car radio code calculator - this is a special program that allows you to select the necessary combinations to unlock the system. There are many such programs on the Internet, so you won’t have any problems finding them.

As practice shows, decoding radios in this way is one of the most common options among our compatriots. But its disadvantage is that it is not always possible to find the combination necessary to unlock AM.

Contacting specialists

Alternatively, decoding of car radios can be carried out by specialized companies, of which there are quite a lot on the domestic market today. Such companies usually accept clients locally, but sometimes a specialist can come to your home. In this case, unlocking the radio is usually done in a matter of minutes, but you will also have to pay for such a service, and sometimes no less than the dealer.

Such companies usually employ professionals who are familiar with technology.

The unlocking procedure itself in this case is carried out as follows:

1. First, a specialist will remove the head unit from the car. Usually, it is enough to use standard keys for dismantling, but sometimes the procedure requires removing the center console, everything is individual here.
2. After this, the device is disassembled - a specialist needs to determine the type of memory used to store the locking combination.
3. Next, the memory is read; for this, a computer with specialized software, as well as additional devices, can be used.
4. Then the specialist will find the place where the necessary code is stored and decrypt it. After this, the decoded device will be ready for further use - the radio tape recorder is put in place.
