How to Find the S/N on a Primastar's Radio
The only thing you'll need to find the corresponding code is your radio's serial number (not part number!).
On all Nissan's, you can find it in one of these places:
- Directly on the radio screen (by using some combinations of buttons)
- On the radio body itself - you'll need to extract it and write down your serial (which is not so hard).
Search for something like: Serial Num., SN, S/N, Serial, Serial Number...
1. View the Serial Number on Nissan Primastar's Screen
Unfortunately, on Nissan Primastar radios the serial number cannot be viewed on the screen.
In that case, you'll need to remove the radio unit and check the label on the back of the radio.
2. How to Find the S/N on the Radio Unit's Sticker
To find the serial number, you'll need to remove the radio unit out.
- Start by turning off the ignition and taking off the dashboard bezel.
- Next, unscrew the mounting bolts and slide the radio out to check the label on the back of the radio. Be careful not to damage the cables that the unit is connected to.
- Write down full serial number carefully and then come back to our website.
- Know that serial number and part number are not the same. You will find both on the unit, but you only need for the first one.

Common Nissan Primastar Radio Code Issues
Many drivers encounter radio lock problems on their Primastar after battery-related issues.
Below are the most typical situations when this can happen.
Lock After a Battery Replacement
After a battery replacement, your radio may stop working.
This happens because the radio detects a power reset, which triggers the anti-theft system.
Other Scenarios
- After a boost start, the radio may lose power and request a radio code.
- When the head unit is replaced, it usually requires the original code.
- If a fuse blows, the radio can enter anti-theft mode.
- After an ECU reset, software update, or electrical repair, some Nissan Primastar radios display a CODE message.
Quick Fixes Before Buying a Radio Code
Before you pay for it, it's worth checking a few places where the code is often already written down.
Some owners find their Nissan Primastar radio code without needing any tools or paperwork.
Here are the most common things to check first.
Look for it in the Vehicle Itself
- In the owner's handbook, often on a separate page.
- In the maintenance records provided with the car.
- On the head unit casing if the unit was previously removed.
- On a sticker in the glove compartment.
- Near the spare tire, where some manufacturers place radio labels.
Can the Dealer Get You the Code?
A Nissan dealer can usually retrieve the radio code using your Primastar's vehicle identification number.
In most cases, you need to contact the service department or visit the dealership and show vehicle documents.
When it is verified, they can request the original anti-theft code for your radio.
Disadvantages:
- You usually need to visit in person and bring vehicle paperwork.
- Dealers often charge a fee for the lookup service and it's sometimes more than 100$.
- The process can take days depending on the model and database.
- Some older Nissan Primastar radios may require manual lookup.
