How to Unlock Your Grundig Radio for Free

If you have a Grundig radio in your car and you need to unlock it, you might be wondering how to do it without paying a dealer or a service. Fortunately, there is a way to get your radio code for free using a simple tool called Grundig Radio Code Calculator. This tool can generate the unlock code for your radio based on its serial number and model. In this article, we will show you how to use this tool and how to enter the code in your radio.

What is Grundig Radio Code Calculator

Grundig Radio Code Calculator is a free software that can help you find the unlock code for your Grundig radio. It works for various models of Grundig radios, such as Alana, Concert, Symphony, and more. You can download it from here[^1^] or here[^2^]. The tool contains two features: Grundig Serial Code Generator and Grundig HEX Code Seeker.

Grundig Serial Code Generator

This feature allows you to enter your radio serial number and it will generate the unlock code for you. The serial number is usually written on a label on the back or on one side of the radio. You need to remove the radio from the dashboard to see it. The serial number usually starts with SEZ, AUZ, or GR.

Grundig HEX Code Seeker

This feature allows you to find the unlock code if you have a radio dump file. A radio dump file is a binary file that contains the data from your radio memory chip. You need to use a special device called an EEPROM programmer to read and write the dump file from your radio. This feature is more advanced and requires some technical skills.

How to Use Grundig Radio Code Calculator

Once you have downloaded and installed the tool, you can follow these steps to use it:

Open the tool and select your radio model from the drop-down menu.

If you have the serial number, enter it in the Serial Number box and click Generate Unlock Radio Code. If you have the dump file, click Browse and select it from your computer and click Seek HEX Code.

The tool will display the unlock code for your radio in a few seconds.

Write down the code and keep it safe.

How to Enter the Code in Your Radio

After you have obtained the code, you can enter it in your radio using these steps:

Turn on your radio and wait for it to display CODE or SAFE.

Use the preset buttons 1-4 to enter the four-digit code. For example, if your code is 1234, press button 1 once, button 2 twice, button 3 three times, and button 4 four times.

Press and hold the SCAN or RDS button until you hear a beep or see CODE OK on the display.

Your radio is now unlocked and ready to use.

Tips and Warnings

If you enter the wrong code three times, your radio will lock up and display SAFE or LOCKED. To reset it, you need to leave the radio on for an hour or more until it displays CODE again.

If you lose or forget your code, you can use the tool again to generate it. However, it is recommended that you write down your code and keep it in a safe place.
