Toyota Aygo Radio Code — Unlock It Online

Your Toyota Aygo radio code is a four-digit security PIN that unlocks the stereo after a power interruption — such as a flat battery, battery replacement, or electrical repair. Once the power is cut, the radio displays CODE or a blank entry screen and will not play until the correct code is entered.

The Aygo has been sold across Europe since 2005 and shares its platform — and audio hardware — with the Peugeot 107 and Citroën C1. That means radio models, serial number formats, and code-entry methods are often identical across all three city cars. This guide covers every Aygo generation and walks you through finding your serial number, retrieving your code, and entering it correctly.

Why Your Toyota Aygo Radio Is Asking for a Code

Toyota's OEM radios include an anti-theft feature that activates whenever the head unit loses power. The moment the battery is disconnected — even briefly — the radio locks itself and requires the four-digit PIN to be re-entered. Common triggers include:

Battery replacement or jump-start
Battery drain leaving the car standing for an extended period
Fuse replacement or electrical work on the vehicle
Removal of the radio unit itself

This is entirely normal behaviour. The code is tied to the radio's serial number, not the vehicle, so as long as you have the serial number you can retrieve the correct code online in minutes.

Toyota Aygo Generations and Radio Fitments

The Aygo has gone through two main generations with two facelifts. All first-generation cars (2005–2014) and many second-generation models (2014–2021) use OEM radios supplied by Panasonic or Pioneer — the same suppliers used by Toyota for the Yaris of the same era. The table below summarises what to expect by generation.

Generation	Years	Typical Radio	OEM Supplier	Entry Method
Aygo I	2005–2009	Toyota OEM CD/radio (CQ-JF10 style)	Panasonic / Pioneer	Preset buttons 1–4
Aygo I facelift	2009–2014	Toyota OEM CD/radio	Panasonic / Pioneer	Preset buttons 1–4
Aygo II	2014–2018	Toyota Touch / OEM unit	Fujitsu Ten / Pioneer	Touchscreen or buttons
Aygo II facelift	2018–2021	Toyota Touch & Go	Fujitsu Ten / Pioneer	Touchscreen

If you own a 2014-onwards Aygo with the Toyota Touch or Touch & Go system, note that later touchscreen-based infotainment units may be vehicle-bound — meaning they re-pair to the car's CAN bus automatically and do not require a standalone PIN. If your screen simply shows normal content after reconnecting power, no code is needed. Only traditional head units with preset buttons prompt for a code.

How to Find Your Toyota Aygo Radio Serial Number

You need the radio's serial number to look up your code. There are two reliable methods:

Method 1 — Display self-test (most Aygo models)

With the radio in the locked CODE state, press and hold the 1 and 6 preset buttons simultaneously for about two seconds.
The serial number will scroll across the display — note it down carefully, including any letters.
If that combination does not work, try holding 2 and 6, or simply press and hold the power/source button.

Method 2 — Label on the radio unit

Use a set of DIN extraction tools (two U-shaped metal keys) to release the radio from the dashboard. On the Aygo the radio slot is typically held by two DIN clips.
Slide the unit out far enough to read the label on the top or side of the casing.
The serial number is printed as a barcode with a numeric string beneath it — usually beginning with a letter prefix.
Slide the radio back in before proceeding.

For the Aygo's OEM Panasonic/Pioneer-sourced radio the serial is typically a 10–14 character alphanumeric string. Record it exactly as printed — case matters. Visit the brands page and select Toyota to retrieve your code once you have the serial.

How to Enter the Code on a Toyota Aygo

Once you have your four-digit code, entering it is straightforward:

Switch on the ignition so the radio powers up and shows CODE (or dashes).
Use preset buttons 1, 2, 3, and 4 to enter each digit of the code. Each press of a button increments that digit position.
For example, to enter the digit 3 in the first position, press button 1 three times.
Once all four digits are set, press the 5 or 6 button (depending on model) to confirm, or wait for automatic acceptance.
The radio will unlock and begin playing immediately.

On Aygo II models with a touchscreen, the code entry screen appears automatically — tap each digit on the numeric pad displayed and confirm.

Troubleshooting Common Error Messages

Entering the wrong code too many times triggers a lockout. Here is what to expect:

CODE — Normal locked state; enter your four-digit code to proceed.
ERR or flashing display — Incorrect code entered; the unit allows a limited number of attempts before locking further.
WAIT — Temporary lockout after multiple wrong attempts. Leave the ignition on for 30–60 minutes, then try again.
LOCKED — Extended lockout after repeated failures. Leave the radio powered on (ignition on, engine off) for one hour, then retry.

If the radio shows LOCKED permanently and will not accept further attempts even after waiting, double-check that you have the correct serial number and re-order the code. A different serial produces a completely different PIN.

Frequently Asked Questions

Where is the serial number on a Toyota Aygo radio?

The serial number is either displayed on-screen by holding preset buttons 1 and 6 simultaneously, or printed on a label on the side or top of the radio unit itself. Removing the radio with DIN extraction keys gives you direct access to the label.

Can I use the same code if I swap the radio into another Aygo?

Yes — the code is tied to the radio's serial number, not the car's chassis. As long as the serial number is the same, the code works regardless of which vehicle the unit is installed in.

My Aygo II touchscreen turned on straight away — do I still need a code?

If the screen powers up normally after reconnecting the battery, the unit has re-authenticated automatically and no code is required. Only radios showing a CODE or dash entry screen need a PIN.

How many attempts do I have before the Aygo radio locks permanently?

Most Toyota OEM units allow between three and ten attempts before imposing a waiting period. After exhausting attempts, leave the ignition on for one hour and the counter resets. There is no permanent hard lock on the Aygo's standard radio.

Do I need to visit a Toyota dealer to get my Aygo radio code?

No. Dealers charge for this service and may require proof of ownership documents. You can retrieve the code online in minutes using the radio's serial number, without needing an appointment.
