Which Toyota models do you support?

We support Toyota Yaris, Corolla, Auris, RAV4, Prius, Hilux, Avensis and most other Toyota models with ERC radios.

ERC stands for Electron Radios Code. It's a 16-character alphanumeric code (letters A–F and numbers 0–9, like a hexadecimal address) that appears on your Toyota radio's display when locked.

How do I find my ERC code?

Turn the ignition on (do not start the engine). The radio display shows 'LOCKED' and below it, your ERC code appears as 16 characters (e.g. 1A2B3C4D5E6F7A8B). Write it down exactly.

What does my unlock code look like?

Your Toyota unlock code is typically a 4-digit number (e.g. 1234). Enter this code into the radio to unlock it and resume operation.

Do I need to remove the radio?

No. The ERC code is displayed on the radio's locked screen. You do not need to remove the radio to see it.

Do you support aftermarket Toyota radios?

No. Our service covers OEM (factory-fitted) Toyota ERC radios only. Aftermarket radios use different locking systems.

Frequently asked questions

What is the unlock code vs. the ERC? +

ERC (Electron Radios Code): The 16-character code shown on your locked radio display. This is what you enter into our lookup.

Unlock Code: The actual PIN you enter into your radio to unlock it. Typically a 4-digit number (e.g. 1234). We provide this after you pay.

You use the ERC to get the unlock code. Then you use the unlock code to unlock your radio.

Can I get the code from a Toyota dealer instead? +

Yes, but it's slow. Toyota dealers can provide codes if you prove ownership with your V5C and photo ID. However:

It usually takes several working days
You must visit the dealership in person
Some dealers charge a fee

Our £4.99 service is instant, online, 24/7.

Do I need to enter the ERC manually or can I copy-paste? +

You can type or copy-paste your ERC into our lookup. We recommend copy-pasting if possible to avoid transcription errors. A single wrong character will result in an incorrect lookup.

If you must type it manually, double-check every character, especially similar ones (0 vs O, 1 vs I, etc.).

What if the code doesn't work? +

We offer a 100% money back guarantee. If the unlock code we provide doesn't work, contact us immediately and we'll refund you in full, no questions asked.

Before entering the code, make sure you have the correct ERC from your radio's display.

Is my ERC private? +

Yes. We do not store your ERC, vehicle details, or personal information beyond what's needed to process your order. We use Stripe for payment. We never see your card details.

We do not sell or share any of your data.
