Toyota C-HR Radio Code — Unlock It Online

Your Toyota C-HR infotainment system has locked after a battery change or power interruption — and you're presented with a code request before anything else will work. This guide explains exactly how to find the serial number on your C-HR's system, how to get the correct unlock code, and how to enter it so you can get back on the road with audio restored.

Why Does the Toyota C-HR Radio Lock?

Toyota equips all its factory radios and infotainment systems with an anti-theft security feature. Any interruption to the power supply — from a battery replacement, a flat battery, or electrical servicing — causes the system to lock and display a code request. The system won't function until the correct code, unique to the unit's serial number, is entered. This makes the radio valueless to a thief without the matching code.

Finding the Serial Number on a Toyota C-HR

Method 1: Button Combination

1. Switch the ignition on so the infotainment system powers up. The display should show the code prompt.
2. Press and hold preset buttons 1 and 6 simultaneously for two to three seconds.
3. The serial number should appear on screen. Note it down exactly, including any letter prefix.

Method 2: System Settings Menu

1. On C-HR models with the Toyota Touch 2 or Toyota Touch 2 with Go touchscreen system, the serial number may be accessible via Settings > System > System Information.
2. The serial number is typically listed as the unit or radio serial.

Method 3: Physical Label

1. Use appropriate trim removal tools to partially pull the head unit from the dashboard.
2. Look on the casing for a white sticker bearing the serial number and a barcode.
3. Transcribe the full serial exactly as printed.

With the serial number in hand, order your Toyota C-HR radio code online for fast email delivery, typically within minutes.

How to Enter the Code on a Toyota C-HR

Touchscreen Entry (Toyota Touch 2 / Touch 2 with Go)

1. When the touchscreen displays the code request, tap on the first digit field.
2. Use the on-screen number pad to enter your four-digit code.
3. Tap OK or Confirm to submit.
4. The system should unlock and return to normal operation.

Button Entry (Standard OEM Radio if fitted)

1. With the radio showing CODE, use preset buttons 1 to 4 to enter each digit by cycling up from 0 to 9.
2. Once all digits are set correctly, confirm with the seek button or button 5.

Toyota C-HR Generation Overview

Generation	Years	Powertrain	Typical Infotainment	OEM Manufacturer
C-HR First Gen	2016–2019	1.2T petrol, 1.8 Hybrid	Toyota Touch 2 / Touch 2 with Go, some 6.1" OEM CD	Fujitsu Ten / Pioneer

The Toyota C-HR launched in 2016 as a bold crossover built on the TNGA platform. Most UK and European examples came with a 1.8-litre self-charging hybrid powertrain and Toyota's Touch 2 or Touch 2 with Go infotainment. The infotainment units were manufactured by Fujitsu Ten (a Toyota-affiliated supplier) and Pioneer. Entry-level C-HRs in some markets received a simpler OEM CD head unit with standard button-based code entry.

Troubleshooting Toyota C-HR Radio and Infotainment Problems

The touchscreen shows the code prompt but input is unresponsive

Try a soft reboot first: turn the ignition fully off, wait 30 seconds, then restart. If the touchscreen remains unresponsive, check whether the display itself is functioning — if it's completely dark, check the relevant fuses.

I entered the code and got an error

An error after code entry means the code was incorrect. The most frequent cause is an incorrectly transcribed serial number. Re-check the serial from the settings menu or button combination and reorder the code with the corrected serial.

The system shows WAIT and locks me out

After several incorrect attempts, the system imposes a timed lockout (typically 60 minutes). Turn the ignition off, wait the full period, and only attempt again when you are confident you have the correct code.

My C-HR is a hybrid — does the 12V battery disconnect affect this?

Yes. The C-HR hybrid uses a conventional 12V battery to power electronics including the infotainment system. If this battery is disconnected or goes flat, the radio security lock activates as usual. The high-voltage hybrid battery is a separate system and does not affect this process.

The code I received doesn't work on the Touch 2 system

Ensure you're entering the code on the touchscreen rather than physical buttons, if your C-HR has the Touch 2 system. Also verify the serial number was submitted accurately. Contact our support team with your order reference for a re-check.

Frequently Asked Questions

Is the Toyota C-HR radio code the same as the vehicle's VIN?

No. The radio code is derived from the infotainment unit's own serial number, not from the vehicle identification number (VIN). You need the unit serial to retrieve the correct code.

Can a Toyota dealer provide the C-HR radio code?

Yes — Toyota dealers can retrieve codes from their system with proof of ownership. Our online service provides the same outcome from the serial number alone, without a dealer appointment, and is available 24/7.

Will the code change if I update the C-HR's software?

No. Software updates via the Toyota service network do not change the radio security code. The code remains the same for the life of the unit.

I have a 2019 C-HR — is it still covered?

Yes. All C-HR models from launch in 2016 through to the end of the first-generation run in 2019 are covered. The code retrieval process is the same regardless of exact model year within this generation.
