Finding the S/N on a Leon's Radio
The only thing you'll need to find the corresponding code is your radio's serial number (not part number!).
On all Seat's, you can find it in one of these places:
- Directly on the radio screen (sometimes)
- On the radio body itself - you'll need to extract it and write down your serial (which is not as hard as it seems).
Search for something like: Serial, SN, S/N, Serial Num...
1. View the Serial Number on Seat Leon's Screen
Unfortunately, on Seat Leon radios the serial number is not shown on the screen.
In that case, you'll need to take out the head unit and check the sticker on the side of the radio.
2. Find the Serial Number on the Radio Sticker
To find the serial number, you'll need to remove the head unit from the dashboard.
- Start by turning off the ignition and removing the trim panel.
- 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 full serial number carefully and come back to our website.
- Know that serial number and part number are not the same. You can find both of them on the unit, and you only need for the first one.

Common Seat Leon Radio Code Issues
Many drivers encounter radio code issues on their Leon after battery-related issues.
Below are the most typical situations when this can happen.
Battery Change Problem
When the battery is replaced, the Seat Leon radio enters anti-theft mode.
This security feature is designed to protect the original head unit by disabling the radio after electrical reset.
Other Situations
- Installing a used head unit will trigger the original radio code.
- After an ECU or software reset, the radio may lock.
- A fuse removal can cause the Seat Leon radio to lock.
- Jump-starting the vehicle can trigger anti-theft mode, requiring the PIN.
Is Getting a Free Seat Leon Radio Code Possible
Before you decide to pay, it's worth checking a few places where the code is often stored.
Some drivers find their Seat Leon 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 vehicle handbook, often on a code card.
- Inside the center console, sometimes on a small card.
- In the trunk, on a radio label.
- In your car paperwork from the previous owner.
- On the head unit itself, if it was serviced earlier.
Can the Dealer Get You the Code?
A Seat dealer can usually retrieve the security code using your Leon's vehicle identification number.
In most cases, you need to contact the service department or visit the dealership and show vehicle documents.
Once 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 ask for payment for the lookup service and it's sometimes more than 100$.
- The process can take days depending on the model and database.
- Some older Seat Leon radios may not be supported.

Now You Have the Code. How to Enter It?
Once you have the Seat's radio code, you can enter it using the infotainment controls.
Most radios display "ENTER CODE", "----" or "XXXX" message when they are locked.
You typically use the number keys to select each digit.
After entering the full code, the radio will restore normal operation.
Be careful, 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 one hour or a set waiting period.
