Peugeot Radio Code (C7)

Peugeot's anti-theft system differs from most other manufacturers in one key respect: the serial number used to generate the unlock code is typically printed on a C7 barcode label — a small adhesive sticker with a barcode and alphanumeric serial — rather than being derivable from a simple button combination. This guide explains where the C7 label is located, how to read the serial from it, and how to unlock your RD4, RD45, RD3, RCC or RT6 radio.

What Is the C7 Barcode?

The C7 label (named after the Peugeot internal reference for this label type) is a small barcode sticker, usually measuring approximately 5 × 2 cm, that carries:

• A barcode (which can optionally be scanned, though manual entry is more common)
• An alphanumeric serial number printed beneath the barcode — this is the number you need
• Sometimes the unlock code itself is printed on this label (check before ordering a retrieval)

The C7 label is applied at the factory to both the radio unit (on the casing) and to the vehicle's documentation — typically the service book, the owners manual wallet, or the original delivery paperwork.

Where to Find the C7 Label

1. Glovebox documentation: Check the service history booklet and any Peugeot wallet for a small sticker or printed card with a barcode.
2. Unit casing: Remove the radio using DIN extraction keys (or prise out the surround panel on integrated units). The C7 label is usually on the top or side of the unit's metal casing.
3. On-screen display (select models): Some Peugeot RD4 and RD45 units support displaying a partial serial by pressing and holding preset buttons 1 and 4 simultaneously with the radio in code-entry mode — try this first to avoid removing the unit.

Once you have the serial from the C7 label, submit it at RadioCodeLookup.com to retrieve your unlock code.

Entering the Code on a Peugeot Radio

1. With the radio showing a code-entry prompt (usually dashes or ----), press button 1 repeatedly to cycle the first digit to the correct value.
2. Press button 2 for the second digit, 3 for the third, 4 for the fourth.
3. Press the volume knob or a dedicated OK/confirm button to submit the code. The exact confirm control varies by model.

On RT6 and some RCC touchscreen models, a keypad appears on the screen — tap each digit and confirm with the on-screen OK button.

Common Peugeot Models That Require a Radio Code

• Peugeot 206 (1998–2009) — RD3 or RD4; C7 on unit casing
• Peugeot 207 (2006–2012) — RD4 or RD43
• Peugeot 208 I (2012–2019) — RD45 or RCC depending on trim
• Peugeot 307 (2001–2008) — RD4 or RD43
• Peugeot 308 II (2013–2017) — RT6 touchscreen
• Peugeot 107 / 108 (2005–2021) — Toyota-sourced unit; label on casing

Troubleshooting

• Cannot find the C7 label in the documentation: Try the on-screen display method (hold 1+4 on RD4/RD45), then remove the unit if that fails. The label should be on the unit casing.
• Code entered but radio still shows dashes: Ensure you confirmed with the correct button. The confirm control differs between RD4 (volume knob) and RT6 (on-screen OK).
• Temporary lockout after wrong code: Peugeot units typically impose a short wait period. Leave the ignition on and wait for the prompt to reappear.

Frequently Asked Questions

Is the code sometimes already printed on the C7 label?

On older models (particularly 206 and 307 with RD3/RD4), yes — the four-digit unlock code is sometimes printed directly on the label alongside the serial. Check both lines of text carefully before assuming retrieval is needed.

Does this also work for Citroën radios?

Yes. Citroën vehicles (C3, C4, Berlingo, Picasso) share the same Philips/VDO RD4 and RT6 platform as Peugeot. The C7 label system, serial format and entry method are identical. Select Citroën at RadioCodeLookup.com to retrieve your code.

My Peugeot 308 II has an RT6 — does it need a serial from the label?

Yes. The RT6 unit has a C7 label on its casing with a serial that is used for code retrieval. The code is then entered via the on-screen keypad rather than physical buttons.

Will removing the radio to read the C7 label cause any problems?

No, provided you do not disconnect the wiring harness or aerial — simply sliding the unit out to read the label is safe. The radio will, of course, display the code prompt again after being reseated, which is expected — you will then have the serial needed to resolve it.
