Peugeot 108 Radio Code — Unlock It Online

Your Peugeot 108 radio is locked and showing a code prompt — almost certainly the result of a recent battery change, a flat battery, or a brief power interruption during workshop servicing. This is entirely normal behaviour for the 108's OEM head unit, and unlocking it requires only the 4-digit code tied to your radio's unique serial number. This guide covers both the 108 I (2014–2018) and the 108 I facelift (2018–2021) in full.

Why the Peugeot 108 Radio Locks

The 108 is a PSA Group city car built on the same platform as the Toyota Aygo and Citroën C1. All three share very similar infotainment architecture — and all three implement the same power-loss anti-theft lock. The moment the radio's 12V supply is interrupted, the unit stores a lock flag and will not operate until the correct code is entered on next power-up.

Peugeot 108 head units were manufactured by Bosch/Clarion and Panasonic/Pioneer, depending on trim level and market. The entry-level trim used a straightforward button-operated unit, while higher specifications received a touchscreen. Both systems respond to the same C7 barcode serial number and standard 4-digit code retrieval process. A temporary lockout applies after too many incorrect entries.

Finding Your Peugeot 108 Radio Serial Number

Peugeot uses a C7 barcode serial number system across all its models. Here are the methods for the 108:

Button combination: Turn ignition to position I (accessories on). With the radio switched off, press and hold preset buttons 1 and 4 together. On many 108 models, the serial number will scroll across the display. On touchscreen variants, try holding the source and volume buttons together, or navigating to the settings menu for a serial number readout.
C7 barcode label: If the button method fails, you will need to remove the head unit from the dashboard. DIN extraction tools (or a flat trim removal tool for snap-fit plastic panels) are required. The serial barcode label is on the top or rear of the unit.
Documentation: Check the 108's original service wallet — some vehicles were supplied with a code card showing the radio serial and unlock code.

With the serial in hand, visit our Peugeot code lookup page to retrieve your code.

Entering the Code on a Peugeot 108

Turn the ignition to position I (accessories on).
Switch on the radio. The display shows CODE.
Button unit: Use preset buttons 1, 2, 3 and 4 to cycle each digit to the correct value. Confirm with the 5 or OK button.
Touchscreen unit: A numeric keypad appears on screen. Tap the digits of your code in order, then press OK or Validate.
The radio unlocks and resumes normal audio operation immediately.

Troubleshooting Error Messages

CODE — Normal locked state; enter your 4-digit code to unlock.
ERR — Incorrect code entered; check the code and try again after the wait period.
WAIT — Temporary lockout after too many wrong entries. Leave the ignition in position I for one hour before retrying.
No display / blank screen — Wait 30 seconds after turning on — some 108 units take a moment to show the CODE prompt. If the screen stays blank, check fuses.

Frequently Asked Questions

Is the Peugeot 108 radio the same as the Toyota Aygo or Citroën C1?

The 108, Aygo, and C1 share the same PSA/Toyota platform and very similar (sometimes identical) head units. The serial number format and code retrieval process are comparable across all three, but the specific code tied to a serial number differs between units. Do not use a code retrieved for a C1 unit in a 108 radio — each serial has its own unique code.

Where is the serial number on a Peugeot 108 I facelift?

On the 108 I facelift (2018–2021) with a touchscreen head unit, the serial is most easily accessed via the radio's settings or service menu — look for a System information or About section within the touchscreen interface. Alternatively, the C7 barcode label is on the unit casing, accessible after removing the unit from the dashboard with trim removal tools.

My Peugeot 108 radio shows WAIT — what should I do?

WAIT means you have exceeded the allowed number of incorrect code attempts. Keep the ignition switched to position I (accessories on, engine off) for a full hour. After that time, the display reverts to CODE and you can try again. Ensure you have the correct 4-digit code before your next attempt to avoid triggering the wait period again.

Can I get the Peugeot 108 radio code without a service history?

Yes. The code is generated directly from your radio's serial number — no service history, VIN number, or dealer account is required. As long as you have the C7 serial from the head unit, MyRenaultRadioCode.com can retrieve your unlock code immediately, regardless of the vehicle's service record or ownership history.
