There are a few simple methods for obtaining the radio security code.

With the correct code in hand, you will be able to restart your stereo and resume listening to music while driving. The following steps will help you find the radio code for your car’s audio.

#1. Retrieve the Serial Number

You need your radio’s serial number before we can unlock it.

To find the label on the radio cover, you’ll need to remove it and look at the top or side of the radio. Manufacturers place the radio’s serial number inside the device in some instances, but this is rare.

To remove the radio, you need radio release keys, which you can purchase online if you do not have them in hand.

In some cases, you may use small screwdrivers to remove the radio; however I do not recommend this due to the potential damages to the equipment.

A combination of buttons is required to display the serial number on specific devices; other devices need the radio to be removed.

I recommend that you first visit the website’s page dedicated to the particular model or manufacturer of your car/radio to acquire further information.

#2. Check Your Car Radio’s Manual

To get a radio code, you can also check the vehicle’s owner handbook or paperwork from the aftermarket stereo.

The owner’s handbook has an alphabetically-arranged index at the back.

You can find out if this information is documented by searching the handbook for radio, stereo, or security sections.

Owner’s manuals or the handbook’s cover may contain a plastic or cardboard card that includes a radio code.

Consider checking the “notes” section of the owner’s manual if you bought the car from a private owner or a used vehicle dealer. Former owners may have recorded the radio’s security code on occasion.

#3. Visit Your Car Radio’s Manufacturer’s Website

If there is no radio security code in your glove box or owner’s manual, you will need to check your car’s manufacturer’s website to locate it.

In many cases, you may input your car’s VIN and serial number into an internet database to acquire the security code or have it emailed to you.

However, if your radio is an aftermarket model, you should contact the manufacturer for assistance.

#4. Contact the Local Dealership

As a last option, you might check with the dealership where the car was purchased or a dealership affiliated with your vehicle’s manufacturer to obtain the radio security code.

To obtain the radio security code may be required proof of ownership, such as car registration or the purchase invoice.
