The Radio Code - What is It and Why It's Important for Maserati GranCabrio?
A radio unlock code, sometimes also known as an anti-theft code is a unique numeric unlock key that reactivates your car audio system after it has been locked.
This factory security PIN is triggered when the radio is disconnected from power.
Car manufacturers use this security system to prevent stolen radios from being reused.
If power is interrupted, the radio disables itself and asks for the CODE before it can work again.
Once the right combination is entered, the stereo is restored to normal operation.
Common Maserati GranCabrio Radio Code Issues
Your radio may request a security code when it loses power.
These are the most common scenarios that trigger the radio code prompt.
Radio Asking for Code After Battery Swap
After a battery replacement, your radio may show a CODE message.
This happens because the radio detects a power reset, which triggers the security lock.
Other Possible Triggers
- If a fuse is pulled, the radio can enter anti-theft mode.
- After a jump-start, the radio may lose power and request a security code.
- After an ECU reset, software update, or electrical repair, some Maserati GranCabrio radios ask for a code.
- When the radio is replaced, it usually requires the original code.
Places to Check First
Before you decide to pay, it's worth checking a few places where the code is often stored.
Some drivers find their Maserati GranCabrio radio code without needing any tools or paperwork.
Here are the easiest things to check first.
Look Inside the Vehicle Documents
- On the radio chassis if the unit was previously removed.
- In the service booklet provided with the car.
- On a sticker in the door pillar.
- In the radio manual, often on a separate page.
- Near the trunk lining, where some manufacturers place radio labels.
Dealer Retrieval Process
A Maserati dealer can usually retrieve the radio code using your GranCabrio's VIN.
In most cases, you need to visit or contact them and prove ownership.
When it is verified, they can generate the original anti-theft code for your radio.
Possible Drawbacks:
- The process can take days depending on the model and database.
- Some older Maserati GranCabrio radios may require manual lookup.
- Dealers often charge a fee for the lookup service and it can cost more than 100$.
- You usually need to book an appointment and bring vehicle paperwork.
Where to Search for the S/N
The only thing you'll need to find the corresponding code is your radio's radio serial. No VIN is needed.
On many Maserati vehicles, you can find it in one of these places:
- Displayed on the radio screen (in some cases by using specific button presses)
- On the radio body itself - you'll need to remove the unit slightly and write down your serial (which is fairly easy)
Search for something like: Serial Number or SN.

The Maserati GranCabrio (2010–2019) shares the same platform and radio system as the GranTurismo — a Becker radio is fitted throughout its production run.

- Turn radio OFF, then press and hold TP for 10 seconds.
- Turn radio ON — display shows "Becker 1".

If the service menu is not accessible, the serial number is on a label on the radio chassis. Physical removal is required. See the removal guide below.
2. 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 pull the unit forward to check the sticker on the back of the radio. Be careful not to damage the cables.
- Write down the serial number precisely and then come back to the website.
- Know that serial number and part number are not equal. You can find both on the sticker, and you only care for the serial.

Serial Number Prefixes You'll See on Maserati GranCabrio
Your Maserati GranCabrio radio serial depends on the unit type: Harman VP4 8.4" units use QNG or BE prefixes, and Continental units start with A2C. The serial is on a label on the radio housing.
Entering the Radio Code on Maserati GranCabrio
Once you have the Maserati's security code, you can type it in using the radio buttons.
Most radios display "ENTER CODE", "----" or "XXXX" message when they are locked.
You typically use the rotary knob to select each digit.
After entering the full code, the radio will restore normal operation.
To enter your Maserati GranCabrio unlock code:
- Turn the ignition ON – The radio displays "CODE" or "----".
- Use preset radio buttons 1-4 to enter your 4-digit code. Press button "1" multiple times until the first correct digit appears, button "2" for the second digit, button "3" for the third digit, and button "4" for the fourth digit.
- The radio unlocks automatically once all 4 digits are entered correctly.
Lockout Warning: After multiple incorrect attempts, the radio may lock for 60 minutes. Keep the ignition ON during the waiting period.
Try not to make mistakes, because too many wrong attempts can disable your radio temporarily.
It will allow you a few incorrect tries before showing a LOCKED message.
You can try again by keeping the ignition on for 60 minutes or a set waiting period.
