Peugeot 107 Radio Code — Unlock It Online

Q: How to Enter the Code on a Peugeot 107

Switch on the ignition. The display shows CODE or four dashes. Use preset buttons 1, 2, 3, and 4 to set each digit. Press button 1 to increment the first digit, button 2 for the second, and so on. Each press adds one to that digit; it wraps from 9 back to 0. When all four digits match your code, press button 5 or 6 to confirm — or on some units the code accepts automatically after a short pause. The display returns to normal and the radio begins operating.

Your Peugeot 107 radio code is the four-digit security PIN your stereo requires after any interruption to its power supply. Disconnect or replace the battery, blow a fuse, or pull the radio out — and the unit locks itself, refusing to play until the correct code is entered.

The Peugeot 107 is a rebadged version of the Toyota Aygo and Citroën C1, all built on the PSA/Toyota A-platform and assembled in the Czech Republic. This shared parentage means all three cars use closely related audio hardware — specifically the CQ-JF10 OEM radio unit, manufactured by Panasonic and Pioneer for the Toyota supply chain and fitted to 107s built between 2005 and 2014. Understanding this makes finding your serial number and entering the code much more straightforward.

Why Does the Peugeot 107 Radio Lock?

The CQ-JF10 and related OEM units fitted to the 107 use a power-loss detection circuit. The moment the head unit loses its permanent live supply — even momentarily — it enters a secured state and requires the PIN before it will operate again. This is a deliberate anti-theft measure, not a fault. Common causes include:

Replacing the 12V battery
Battery fully discharged after the car has been standing
Disconnecting the battery for maintenance or bodywork
Removing the radio unit for any reason

Peugeot 107 Generations and Radio Models

Generation	Years	Radio Model	OEM Supplier	Code Needed?
107 I (A-platform)	2005–2009	CQ-JF10 (Toyota OEM)	Panasonic / Pioneer	Yes
107 I facelift	2009–2012	CQ-JF10 or updated OEM unit	Panasonic / Pioneer	Yes
107 II	2012–2014	OEM unit (A-platform)	Panasonic / Pioneer	Yes

All three generations of the 107 use variants of the same Panasonic/Pioneer-sourced OEM radio. Higher-spec models may have a CD changer or Bluetooth integration, but the underlying head unit and code mechanism remain consistent across the entire production run. For codes covering related PSA models, see the brands page.

How to Find the Peugeot 107 Radio Serial Number

The serial number is required to generate your code. Two methods work on the 107:

On-screen serial number display

Turn on the ignition so the radio shows CODE (or dashes awaiting input).
Press and hold preset buttons 1 and 6 simultaneously for two seconds.
The serial number scrolls across the display. Write it down in full.
Alternatively, try holding preset buttons 2 and 6 together if the above does not respond.

Reading the label from the unit

Insert DIN extraction tools (two flat U-shaped keys) into the slots on either side of the radio bezel.
Pull the unit straight out — it slides on DIN rails.
The serial number barcode label is on the top or side of the unit. Note the full alphanumeric string beneath the barcode.
Slide the unit back in firmly before looking up your code.

The CQ-JF10 serial typically begins with alphanumeric characters and is 10–12 digits long. The serial on the Peugeot 107 version may differ slightly in prefix from Toyota-branded units, but the code look-up process is identical.

Each press adds one to that digit; it wraps from 9 back to 0.

Error Messages and Lockout Situations

CODE — Standard locked state; enter the PIN.
ERR — Wrong code entered; the unit still accepts further attempts at this stage.
WAIT or frozen display — Too many wrong attempts in succession. Leave the ignition on for 30–60 minutes; the timer resets automatically.

The 107's OEM unit does not impose a permanent hard-lock, but repeated wrong entries extend the wait time. Always double-check your serial number before attempting entry — a single incorrect character in the serial produces a completely different code.

Frequently Asked Questions

Is the Peugeot 107 radio the same as the Citroën C1 and Toyota Aygo?

Yes — all three share the A-platform and use the same Panasonic/Pioneer CQ-JF10 OEM radio. The serial numbers differ between units, but the code format and entry method are identical across all three models.

Where exactly is the serial number on the Peugeot 107 CQ-JF10 radio?

It appears on a barcode sticker on the top or side of the unit. You can also display it on-screen by holding presets 1 and 6 together when the radio is in the CODE state.

My Peugeot 107 shows CODE but I've tried the code and it says ERR — what now?

Double-check that you have the correct serial number — re-reveal it using the button combination or re-read the label. Then re-order a fresh code. If the code still fails, verify the serial was not partially obscured on the label.

Can I use the 107 radio in a different car after unlocking it?

Yes. The code is permanently associated with the unit's serial number. Once unlocked, the radio will work in any car. It will only re-lock if power is interrupted again — at which point the same code applies.
