Common Hyundai Kona Radio Code Issues
Many owners encounter radio lock problems on their Kona after battery-related issues.
Below are the most common situations when this can happen.
Radio Asking for Code After Battery Change
After a battery change, your radio may lock.
This happens because the radio recognizes a voltage interruption, which activates the anti-theft system.
Other Situations That May Trigger the Code
- If a fuse is pulled, the radio can lock itself.
- When the radio is replaced, it usually locks automatically.
- After an ECU reset, software update, or electrical repair, some Hyundai Kona radios ask for a code.
- After a jump-start, the radio may reset and request a security code.
Check These Free Methods
Before you decide to pay, you should check a few places where the code is often stored.
Some owners find their Hyundai Kona radio code without needing any tools or paperwork.
Here are the easiest things to check first.
Search the Vehicle Interior
- In your maintenance booklet from the previous owner.
- Inside the glovebox, sometimes on a label.
- In the vehicle handbook, often on a code card.
- On the radio unit itself, if it was removed before.
- In the trunk, on a radio label.
Can You Get a Hyundai Kona Radio Code from the Dealership?
A Hyundai dealer can usually look up the security code using your Kona'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 generate the original anti-theft code for your radio.
Possible Drawbacks:
- You usually need to visit in person and bring ID.
- Dealers often ask for payment for the lookup service and it's sometimes more than 100$.
- Some older Hyundai Kona radios may not be supported.
- The process can take days depending on the model and database.
How to Locate the Serial Number on a Kona
The only thing you'll need to get the code is your radio's radio serial. No extra vehicle data is required.
On almost all Hyundai vehicles, you can find it in one of the following locations:
- Visible on the radio screen (sometimes by using button combinations)
- On the radio housing itself - you'll need to remove the unit slightly and write down your serial (which is usually simple)
Search for a label such as: S/N or Serial.
1. Viewing Kona's S/N on the Display
Hyundai Kona radio does not show the serial number on the screen.
Unfortunately, the unit must then be physically removed to find the serial on a manufacturer label on the radio casing.
2. Find the S/N on the Radio Body
To find the serial number, you'll need to pull out the radio unit from the dashboard.
- Start by turning off the ignition and removing the trim panel.
- Next, unscrew the mounting bolts and slide the radio out to check the sticker on the back of the radio. Be careful not to damage the connections.
- Write down the serial number precisely and then come back to the website.
- Know that serial number and part number are not the same. You will find both of them on the unit, but you only care for the serial.

How to Enter the Unlock Code on Your Vehicle
Once you have the Hyundai's unlock code, you can type it in using the infotainment controls.
Most radios display "ENTER CODE", "----" or "XXXX" message when they are locked.
You typically use the rotary knob to input the code.
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 SAFE message.
You can reset the lockout by keeping the ignition on for 60 minutes or a set waiting period.
