Owners Nissan Note (especially models E11 And E12) often encounter the problem of a locked radio after disconnecting the battery or replacing the battery. The system requires you to enter 4 digit code, without which the audio system remains inoperative. This situation causes panic, especially if the original documentation with the code has long been lost.

In practice, unlocking the radio is a solvable task, but requires strict adherence to the instructions. In this article we will look at all ways to get the code (from official to alternative), we will describe the input process in detail, and also tell you what to do if the standard methods do not work. We will pay special attention unique nuances for Nissan Note with radios Clarion And Panasonic, which were often installed on these models.

Why a radio Nissan Note does it require a code?

Locking the radio is anti-theft function, activated when the power supply is interrupted (for example, when replacing the battery or removing terminals). Manufacturer Nissan uses it on most models, including Note E11 (2004–2013) and Note E12 (2013–2020). The principle of operation is simple: after power is restored, the system requests a unique code, which:

  • 🔐 Linked to the serial number of the radio (not to the car!).
  • 📄 Indicated in the original documentation (owner’s book or on a separate card).
  • 🔄 May need to be repeated if the power goes out again.

On Nissan Note Most often, two types of radio tape recorders were installed:

  • 🎵 Clarion (models PU-2294A, PU-2394) - standard for Note E11.
  • 📻 Panasonic (series CQ-RDP1) - found on Note E12 and restyled versions.

If you bought the car second-hand, the previous owner may not have passed on the code. In this case, you will have to restore it yourself or through a dealer.

Where can I find the original radio code?

Before proceeding with complex manipulations, check standard seats, where the code could be saved:

  1. Car owner's book - the code is sometimes printed on the last pages or on an insert.
  2. Separate card (usually plastic) with an inscription Anti-Theft Radio Code or Security Code.
  3. Glove compartment or glove compartment — previous owners often leave it there.
  4. Email — if the car was purchased at a dealership, the code could be sent by email.

If the code is not found, move on to alternative methods. But first make sure the radio is locked, but did not fail. Signs of blocking:

  • 🔊 The display lights up CODE, ENTER CODE or SAFE.
  • 🎶 There is no sound, but the buttons respond to pressing.
  • ⚡ When you turn on the ignition, the radio flashes, but does not start.
💡

If the display shows ERR or WAIT, this means that there were too many invalid input attempts. Wait 1-2 hours for the system to unlock automatically.

How to find out the serial number of the radio to restore the code?

To obtain a code through a dealer or online services you will need radio serial number (Serial Number). It can be found in two ways:

Method 1: On the radio itself

If the radio is removable (not built into the panel), remove it from the slot:

  1. Turn off the ignition.
  2. Use special keys (usually included with the car) or suitable screwdrivers to pry off the front panel.
  3. There will be a sticker on the top or side of the case with the serial number (format: CL0412345678 for Clarion or PC1234567 for Panasonic).

Method 2: Through the radio menu (without ejecting)

On some models Nissan Note E12 You can find out the serial number without removing the device:

  1. Hold the buttons 1 + 6 (or AS + Seek for Panasonic) for 5 seconds.
  2. A combination of letters and numbers will appear on the display - this is Serial Number.
What to do if the sticker has worn off?

If the serial number on the radio is unreadable, try wiping it with alcohol or taking pictures from different angles. If this does not help, contact the service - they can remove the case and find the number on the board.
