Issue with the radio unit

Hello! I can help you with that. The radio going into Safe mode after a battery change is a common security feature in many car radios. To unlock your radio, you will need the specific unlock code for your car's radio unit. There are a few different options to obtain the unlock code:

1. Check the vehicle's documentation: Look through your vehicle's owner's manual, service history, or any other documents that came with the car. Sometimes the unlock code is written down in these materials.
2. Contact the dealership: If you're unable to find the unlock code in your vehicle's documentation, the dealership is usually the best place to obtain it. Provide them with your car's VIN (Vehicle Identification Number) and the serial number of your radio unit. They should be able to look up the code for you. Note that some dealerships may charge a fee for this service.
3. Online radio code generators: There are several websites that offer online radio code generation services. These services typically require you to provide the radio's serial number and sometimes the vehicle's VIN. They will then generate the unlock code for you. However, be cautious when using these services, as some may not be reliable or may charge a fee.
4. Check the manufacturer's website: Some car manufacturers provide online tools or customer support services on their websites that can help you retrieve your radio's unlock code. Visit the manufacturer's website and look for a section related to car radios or audio systems. Enter the necessary information, such as your car's VIN or radio's serial number, and follow the instructions provided.

Remember, it's important to ensure that you're using a trusted and reliable source when obtaining the unlock code.
