Check these places to save time and money before using an online generator.
Below are the most reliable places to look.
Look Through the Owner's Manual

This is the official way to restore access to the factory radio.
Drawbacks:

How to Locate the Serial Number on Your Radio
To retrieve the correct unlock code, you will need the radio serial number from your Ford Fiesta's radio unit.
You can usually find it directly on the screen. Common labels to look for: S/N, SN, Serial, Serial Number.
1. How to See the Serial Number on the Fiesta Screen
The Ford Fiesta (2002–2008) was typically fitted with the Ford 6000CD or Ford 4500 RDS radio, both of which support an on-screen display method.

M123456).

Step 1: Turn off the car.
Step 2: After that, remove the dashboard.
Step 3: Then unscrew the radio brackets.
Step 4: Carefully slide the unit out partially (Be careful not to damage the cables).
Step 5: Search for the serial number on the rear of the unit.
Step 6: Write down the full number carefully and come back here so that we can generate the code.
Important: Don't mix the Serial Number for the Part Number!

Usual Serial Letters and Numbers on Ford Fiesta Factory Units
The radio uses a serial beginning with M or V, followed by 6 digits — for example M054321. TravelPilot navigation units start with BP. The serial label is on the top or side of the radio unit.
Entering the Radio Code on Your Fiesta
You need to enter the code into the system to unlock your Ford's radio.
In the locked unit, the screen usually displays a code prompt.
Based on the radio, use radio presets, control knob, or touchscreen to enter the numbers, then submit the code to restore radio functionality.
To input the unlock code on your Ford radio:
- Turn the ignition to ON and power on the radio.
- The display will show "CODE" or "ENTER KEY CODE".
- Use the preset buttons (1–4) to enter each digit of your 4-digit code. Press each button the number of times corresponding to the digit (e.g. press button 1 three times for digit 3).
- After entering all 4 digits, press button 5 or ENTER to confirm.
Tip: On some Ford models (e.g. Sony MP3), you can enter the code directly using the numbered buttons instead of cycling preset buttons.
Frequent Questions about Ford Fiesta Radio Code
Yes. Each radio unit has its own unlock code.
A second-hand radio will need its correct security code to work.
Not all of them require a security code, but many factory radios use it as an anti-theft feature.
Certain series may still use a code depending on the head unit.
Free codes are uncommon.
You might locate the code in the owner's booklet or from a dealer, but most require a serial number lookup.
The most common method is to hold preset buttons 1 and 6 at the same time on Ford 6000CD and Sony MP3 radios. For the Ford 4500 RDS, hold buttons 2 and 6 instead.
Not all Ford radios support on-screen serial display. If the button method doesn't work for your model, the serial number is printed on a label on the top or side of the radio unit, which requires physical removal to view. See our full guide for all methods.
The following Ford radio models can show the serial number on screen: 6000CD, 6000CD MK2, 4500 RDS E-O-N, Sony MP3, and some Travelpilot navigation units.
Older Ford radios and some models without a digital display do not support this feature. In those cases, physical removal is the only way to access the serial number label.
