Their stock radios are found in popular vehicles from automakers, such as Toyota, Mazda, Subaru, Honda, GM and Volkswagen. Panasonic radios include a theft-deterrent feature that requires you to enter a security code after changing the vehicle's battery. As long as you know the original four-digit code, you can reset the security code for your Panasonic radio in just seconds.

Reset your Panasonic radio after each vehicle battery change, or whenever the "Code" error message appears on the radio's digital display. To reset the radio, enter the four-digit security code.
