Which Citroën models do you support?

We support Citroën C1, C2, C3, C4, C5, Xsara, Berlingo and Picasso fitted with Clarion C7 radios.

What is a Clarion C7 radio?

Clarion C7 is the factory-fitted radio used across Citroën's range in the 2000s and 2010s. It's an OEM unit with a barcode serial printed on the chassis or shown on the display.

Where do I find the barcode serial?

It shows on the locked radio's display for most units, or on a label on the radio's chassis if not. The serial itself is usually 4–8 digits.

Why does Citroën use the same radio as Peugeot?

Citroën and Peugeot were part of the same manufacturing group (formerly PSA, now Stellantis) and shared platforms and electronics during this era, including the Clarion C7 unit. The serial format and unlock process are identical between the two brands.

Do you support newer Citroën models?

Our service covers Clarion C7 radios, typically fitted up to around 2013–2014. Newer Citroën vehicles use different, usually touchscreen, radio systems. Try our universal lookup for these.

Do I need to remove the radio?

Usually not. Most Clarion C7 units show the barcode serial directly on the locked display. You'd only need to remove it if the display doesn't show a serial.

Frequently asked questions

Is Clarion a Citroën brand? +

No. Clarion is an independent Japanese electronics manufacturer. Citroën used their C7 model as its factory-fitted radio throughout the 2000s and 2010s, but Clarion also supplied other manufacturers with different units.

Do you support the newer touchscreen Citroën systems? +

Our service is built around the Clarion C7 series, generally found in models up to around 2013–2014. Later Citroën infotainment systems use different security methods entirely.

If your Citroën is newer, try our universal lookup, it may still cover your serial format.

Can I get the code from a Citroën dealer? +

Yes, though it's typically slower. You'll need to prove ownership with your V5C and photo ID. Expect several working days and a fee.

Our £4.99 service is instant and available online any time.

How many wrong attempts can I make? +

Clarion C7 units generally allow 3–10 incorrect attempts before locking out permanently, at which point a dealer reset is needed. Double-check any code before entering it.

If the code we sent doesn't work, we'll refund you in full under our 100% money back guarantee.

Is my information kept private? +

Yes. We keep only what's needed to process your order. Card payments run through Stripe, so we never handle your card details directly, and we don't sell or share customer data.
