Ford Radio Code (M/V)

Ford radios use a distinctive serial numbering system where every serial begins with either the letter M or the letter V — giving rise to the common names M-code and V-code. The 6000 CD is by far the most widely encountered unit, but the same system applies to the 4500 RDS, 4000 RDS, Sony DAB and earlier SYNC units. This guide covers finding the serial, retrieving the code online and entering it correctly — including the critical rules about attempt limits.

Ford's M and V Serial Format

Ford radio serials follow the pattern: one letter (M or V) followed by five to six digits (e.g. M123456 or V234567). The letter indicates which OEM built the unit (Visteon predominantly) and which code algorithm applies. Both letter types use the same retrieval process; you simply enter the full serial as displayed.

These units were standard equipment across Ford's range from the mid-1990s through to approximately 2017, when SYNC 3 became predominant. The 6000 CD in particular was fitted to almost every Fiesta, Focus, Mondeo, C-Max and Transit Connect produced between 2003 and 2011.

How to Find the Serial Number on a Ford Radio

Ford 6000 CD — On-Screen Method

Turn the ignition to position II (radio powered on).
With the radio showing CODE, press and hold preset buttons 1 and 6 simultaneously for about two seconds.
The serial number will appear on the display. Note all characters — it typically scrolls in two halves.

Ford 4500 RDS and 4000 RDS

These smaller units do not support on-screen serial display. Slide the unit out using DIN extraction keys and read the M- or V-serial from the label on the top of the casing.

SYNC 1 / SYNC 2

Ford SYNC units use a different authentication mechanism. The serial for retrieval purposes may be accessible via Settings > System > About or from the unit label. Note that SYNC 3 and newer are VIN-bound and do not use a code.

With your serial in hand, head to RadioCodeLookup.com and select Ford to retrieve your code immediately.

Entering the Code on a Ford Radio

Press button 1 repeatedly to cycle the first digit to the correct number.
Press button 2 for the second digit, 3 for the third, 4 for the fourth.
Press button 5 (or the asterisk * button on some models) to confirm the code.

Critical warning: Ford units — particularly the 6000 CD — count incorrect attempts cumulatively across the unit's entire lifetime. After ten total incorrect entries (across any number of sessions), the unit enters a permanent LOCKED state that requires dealer diagnostic equipment to reset. Always verify the code is correct before entering it.

Troubleshooting Ford Radio Lock Issues

Display shows LOCKED: This means the ten-attempt limit has been exhausted. A dealer with Ford IDS or FDRS diagnostic software can unlock the unit's attempt counter.
Display shows a countdown timer (e.g. 0:60:00): The unit has imposed a temporary lockout after three consecutive wrong entries in one session. Wait for the timer to expire before trying again.
Code accepted but no audio: Check the audio fuse (typically fuse 12 or 13 in the instrument panel fuse box) and ensure volume is not muted.

Frequently Asked Questions

What is the difference between an M-code and a V-code serial?

Both refer to the first letter of the serial number. V-serials are more common on post-2005 units; M-serials on earlier variants. The code-retrieval process and entry method are identical for both. Simply enter the full serial including the leading M or V.

Can I get the serial without a radio removal tool?

For the 6000 CD, yes — the 1+6 button combination displays the serial on-screen. For older 4000/4500 RDS units there is no on-screen method, and a pair of DIN extraction keys (widely available for under £5) will be needed to slide out the unit.

My Ford Focus Mk4 does not ask for a code after the battery was changed — is that normal?

Yes. The Focus Mk4 (2018 onwards) is fitted with SYNC 3, which is vehicle-bound and does not use a serial code. No code is required after a power loss on these systems.

Where can I get the Ford radio code without going to a dealer?

Submit the M- or V-serial at RadioCodeLookup.com. Select Ford, enter the serial and receive the code within minutes — at a fraction of dealer charges and with no appointment needed.
