Toyota Radio Code — Find Your Serial Number

A Toyota radio showing a code prompt after a battery change is locked in its standard anti-theft mode. All Toyota OEM units — from the basic Panasonic-made head unit in a Yaris to the Toyota Touch & Go touchscreen in a C-HR — store a four-digit unlock code that you need to re-enter after any power interruption. This guide shows you exactly where to find the serial number and how to enter the code on every common Toyota radio generation.

Toyota Radio Serial Number: Where to Find It

Toyota OEM radios are manufactured by Fujitsu Ten (now Denso Ten) and Panasonic. The serial number label is on the casing of the head unit. Unlike some other brands, Toyota does not currently offer an on-screen serial display for most basic units — you will usually need to access the unit itself.

• Basic DIN units (Yaris, Aygo, Corolla) — the serial label is on the top or side of the head unit casing. Removal requires Toyota-specific DIN keys or a thin tool to release the internal clips from the side slots of the aperture. On some Yaris and Aygo models the unit is behind a plastic surround panel that must be removed first.
• Toyota Touch / Touch & Go — these integrated touchscreen units on C-HR, Auris II and Yaris III often display the serial under Setup → System → Version or Settings → General → About. Navigate there before reaching for a screwdriver.
• CQ-JF10 OEM unit — this Panasonic-built unit fitted to C1 (shared platform) has the serial on the top casing label.

How to Enter a Toyota Radio Code

Button-based OEM units (Yaris I/II, Aygo I/II, Corolla IX)

1. Switch on the ignition so the radio displays the code prompt.
2. Press preset buttons 1–4 to cycle through digits 1 to 4 respectively. Each press increments the digit.
3. Once all four digits are set, press the confirm button (labelled OK or indicated by an arrow) to submit.
4. The radio displays its normal interface and operation resumes.

Toyota Touch / Touch & Go (touchscreen)

1. The touchscreen displays a code-entry keyboard after power is restored.
2. Tap each digit of the four-digit code on the on-screen keypad.
3. Tap Enter or OK to confirm.

Troubleshooting Toyota Radio Lock States

• No code prompt after battery change — some Toyota Touch & Go systems are VIN-linked and auto-authorise on battery reconnection. If no prompt appears, the radio may not need a code.
• Timed lockout after wrong entry — most units allow three to five incorrect entries before imposing a wait period. Leave the ignition on for at least one hour.
• Display blank after power restored — check the relevant fuse (consult your vehicle handbook; typically fuse 11 or 22 in the passenger cabin box on Yaris models).
• Code accepted but no sound — a muted or low volume setting saved before the battery was disconnected may be the cause. Increase the volume after unlocking.

Frequently Asked Questions

Who makes Toyota OEM radios?

Toyota OEM radios are primarily supplied by Fujitsu Ten (rebranded Denso Ten in 2015) and Panasonic, with Pioneer supplying units for later Touch & Go and Touch multimedia systems. All units regardless of manufacturer use the same code-entry process described above.

How do I remove the radio from a Toyota Yaris to find the serial?

On Yaris II and III models, the radio is housed behind a plastic centre console panel. Use a trim removal tool to carefully prise the surround panel away (it is clipped rather than screwed). Once the surround is off, the DIN aperture gives access to the release slots. Insert DIN keys or a flat tool to release the clips and slide the unit out. The serial label is on the top of the casing.

Does the Toyota Aygo use a different code to the Citroën C1 and Peugeot 107?

The Aygo I shares its platform and the same CQ-JF10 Panasonic unit with the Citroën C1 and Peugeot 107. However, the code is unit-specific — two identical radio models will have different serials and different codes. Always use the serial from the specific unit in your car.

My Toyota Touch & Go screen is frozen on the code entry screen. What should I do?

Hold the power button for 10 seconds to force a soft reset of the head unit. After the system reboots, the code entry screen should appear normally. If the screen remains frozen, there may be a hardware fault unrelated to the anti-theft code.

Can I find my Toyota radio code via the VIN?

Toyota dealers can in some cases cross-reference the VIN to the radio serial in their records and supply the code. However, the process can take several days and may incur a charge. Our online lookup using the radio serial number is faster and available 24 hours. Look up your Toyota code here.
