Common Acura NSX Radio Code Issues
Your radio may enter anti-theft mode when it loses power.
These are the some well-known scenarios that activate the radio code prompt.
Battery Change (Most Common)
After a battery change, your radio may lock.
This happens because the radio recognizes a voltage interruption, which activates the anti-theft system.
Other Possibilities
- Installing a used head unit will require the original anti-theft code.
- After an ECU or software reset, the radio may lock.
- A blown fuse can cause the Acura NSX radio to request a security code.
- Jump-starting the vehicle can trigger anti-theft mode, requiring the unlock code.
What Exactly is a Radio Code?
A radio unlock code, also known as an anti-theft code is a unique numeric unlock key that reactivates your car audio system after it has been disabled.
This security code is triggered when the radio detects a power interruption.
This system helps prevent stolen radios from working in other vehicles.
If power is interrupted, the radio stops functioning and asks for the CODE before it can function normally.
Once the correct numbers is entered, the stereo is fully reactivated.
Can I get a Free Acura NSX Radio Code?
Before you pay for it, you should check a few places where the code is often already written down.
Some owners find their Acura NSX radio code without needing any tools or paperwork.
Here are the easiest things to check first.
Look for it in the Vehicle Itself
- In the vehicle handbook, often on a sticker page.
- Inside the glovebox, sometimes on a small card.
- In the spare wheel area, on a radio label.
- In your service book from the previous owner.
- On the head unit itself, if it was removed before.
Getting a Acura NSX Radio Code from the Dealer
A Acura dealer can usually retrieve the security code using your NSX's vehicle identification number.
In most cases, you need to contact the service department or visit the dealership and prove ownership.
Once verified, they can generate the original anti-theft code for your radio.
Disadvantages:
- You usually need to book an appointment and bring ID.
- 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 Acura NSX radios may not be supported.
Searching for the Serial Num. on your NSX
To get the correct unlock code, you first need the radio serial number.
Depending on your NSX, you can see it on the screen or find it on the radio unit itself.
It's usually written down as S/N, SN, Serial, Serial Num., Serial Number...
These are the easiest ways to locate it:
1. Viewing NSX's S/N on the Display
Acura NSX radio does not show the serial number on the screen.
Unfortunately, the unit must then be physically removed to find the serial on a factory sticker on the radio casing.
2. Locating the Serial Number on the Radio Unit
To find the serial number, you'll need to take out the head unit from the dashboard.
- Start by turning off the vehicle and removing the trim panel.
- Next, release the clips and pull the unit forward to check the label on the side of the radio. Be careful not to damage the cables that the unit is connected to.
- Write down full serial number precisely and then come back to our website.
- Know that serial number and part number are not equal. You can find both on the unit, and you only need for the first one.
