Toyota C-HR Radio Code & ERC Unlock Guide (2026)

Is your Toyota C-HR Japanese import car radio asking for a security PIN or displaying an ERC lock screen after a battery disconnect? You do not need to replace your full head unit or pay high dealership fees. This 2026 step-by-step guide shows you how to retrieve your 16-digit ERC security code and receive a guaranteed unlock PIN within 0–10 minutes.

Why Does the Toyota C-HR Navigation System Lock?

Toyota factory navigation units fitted in the C-HR are equipped with an automatic anti-theft security lock (ERC – Electronic Resource Code). Whenever the main vehicle battery is replaced, disconnected, or experiences a power loss, the head unit memory resets and prompts for a security password on startup.

3 Easy Steps to Unlock Your Toyota C-HR Radio

Step 1: Locate Your 16-Digit ERC Serial Code

Turn on your Toyota C-HR ignition. Press and hold the main menu button on your navigation display while toggling your headlight switch ON and OFF 3 to 4 times until the hidden service screen appears. Select the ERC / Security option to view your unique 16-digit ERC Serial Code.

Step 2: Send Your ERC Code to WhatsApp Support

Take a clear photo of the 16-digit ERC code displayed on your C-HR screen and send it to our 24/7 technical team. We calculate the official factory unlock PIN instantly using our Toyota ERC algorithm.
