Peugeot 207 Radio Code — Unlock It Online
Your Peugeot 207 radio is locked and asking for a code? This is standard behaviour for the RD4 or RD43 head unit when the battery has been disconnected or drained. The PSA Group anti-theft system locks the unit until you enter the four-digit unlock code matched to the unit's serial number. This guide gives you every step, from finding the serial to entering the code — for both the original 207 (2006–2009) and the facelift (2009–2012).
Why Does the Peugeot 207 Radio Lock?
PSA Group (Peugeot-Citroën) equipped the 207 with radio security codes as standard. The RD4 and RD43 head units — manufactured by Philips/VDO — detect any loss of power and activate the immobiliser. The display shows CODE or goes blank, waiting for the correct four-digit unlock sequence. This system means a stolen head unit is worthless without the matching code.
Finding the Serial Number on a Peugeot 207
The serial number can usually be retrieved without removing the RD4 or RD43 unit from the dashboard:
- Button combination (most 207 models): With the radio switched off, press and hold preset buttons 1 and 6 simultaneously for five to eight seconds. The serial number will appear or scroll on the display.
- C7 barcode label: If the button combination doesn't work, use a trim removal tool to partially slide out the unit and read the C7-format barcode label printed on the unit body. This barcode encodes the serial number.
The serial is typically eight to ten characters. Once you have it, order your Peugeot 207 radio code here — it arrives by e-mail within minutes.
How to Get Your Peugeot 207 Radio Code
- Retrieve the serial number using the button combination or from the C7 barcode label.
- Visit radiocodelookup.com and enter the serial and your e-mail address.
- Pay securely; your four-digit code is delivered immediately by e-mail.
- Enter the code on the RD4/RD43 head unit as described below.
How to Enter the Radio Code on a Peugeot 207
The Peugeot 207 uses preset button entry on the RD4 and RD43 units:
- Switch on the ignition (position II) and wait for the CODE prompt to appear on the display.
- Press preset button 1 repeatedly to dial in the first digit of your code (e.g. press three times for digit 3).
- Press the Seek/Scan button (right arrow) to confirm the first digit and move to the second position.
- Repeat for digits 2, 3, and 4.
- After the fourth digit, press and hold the Seek/Scan button — or the dedicated OK button on some variants — to confirm the full code.
- If the code is correct, the radio will unlock and begin playing.

Troubleshooting Peugeot 207 Radio Issues
- Blank screen after battery change: Switch on the ignition (position II) and wait 30 seconds. If the screen remains blank, check the fuse for the radio circuit (usually fuse box under the dashboard, consult the owner's manual for the exact fuse number).
- CODE prompt: The unit is ready for your four-digit unlock code. Enter it carefully using the preset and seek buttons.
- Locked after wrong entries: PSA radios allow up to 10 attempts. After exceeding the limit, a one-hour wait is imposed with the ignition on. The CODE prompt will reappear after the wait.
- 207 facelift with RD45 or display unit: Some 2009–2012 facelift models were upgraded to an RD45 unit with slightly different button logic. The entry process is the same but the confirm button may be labelled differently — try OK or the central button on the d-pad control.
Frequently Asked Questions
How do I get the serial number of a Peugeot 207 radio?
With the radio switched off, press and hold presets 1 and 6 simultaneously for five to eight seconds. The serial number will display on screen. If that doesn't work, slide the RD4/RD43 unit out using a plastic trim tool and read the C7 barcode label on the unit casing.
What do I do if my Peugeot 207 radio says CODE?
CODE means the radio is waiting for your four-digit unlock number. Retrieve your serial number using the method above, order the code online, then enter it using the preset buttons (1–4) and confirm with the Seek or OK button as described in the steps above.
How many wrong attempts can I make before the Peugeot 207 radio locks?
The RD4 and RD43 units allow up to 10 wrong attempts before imposing a temporary lockout. After exceeding 10 attempts, leave the ignition in position II for one hour. The CODE prompt will reappear, giving you another set of attempts.
Can I enter the Peugeot 207 radio code without the ignition on?
The head unit needs power to accept a code entry. Switch the ignition to position II (accessories on, engine off) to supply power to the radio before attempting entry. Do not start the engine during the process.
What is the RD43 radio in the Peugeot 207?
The RD43 is the CD head unit fitted to 207 models from 2006 onwards, manufactured by Philips/VDO for PSA Group. It features AM/FM/CD playback, four preset buttons, and a seek/scan button — the same entry interface used for the older RD4. Both units respond identically to the code-entry method described above.
