In this article we will look at where to find the code for your radio, how to enter it correctly and what to do if the original code is lost.

It is important to understand that the lock code is not a universal combination, but a unique set of numbers tied to the device serial number. It cannot be selected at random: after several unsuccessful attempts, the radio may become permanently blocked, requiring a service call. We've compiled proven ways to get your code, including official and alternative methods, and explained how to avoid common typing mistakes.

Why does my Nissan Juke radio require a code?

The radio lock is a standard anti-theft feature that is activated in several cases:

  • 🔋 Battery disconnection (even short-term) or replacement.
  • 🔧 Dismantling the radio for repair or replacement.

  • 🔄 Reset the radio settings through the service menu.

B Nissan Juke of the first and second generations (2010–2019), radio tape recorders were most often installed Clarion or Bose with a 4-digit code.

If the code is not found, it can be requested from an authorized dealer Nissan. For this you will need:

  • 📄 Vehicle passport (PTS) or registration certificate.
  • 🆔 Serial number of the radio (how to find it out - read in the next section).
  • 📞 Contact information to confirm car ownership.
