- 1Turn the unit on.
- 2Press and hold the map button (“current location”).
- 3Still holding it, switch the car’s parking lights on and off 3 or 4 times until a new screen appears.
- 4Press the one button lit up on that screen. The 16-character ERC is displayed.
Do not take this one out — it will not help. The sticker on the case carries a serial number, but it is not the ERC and it will not unlock the unit. The ERC only ever appears on screen.

Daihatsu model coverage
Our lookup supports Daihatsu radios that display a 16-character ERC on the locked screen, the Denso system shared with Toyota. Commonly:
- Sirion
- Terios
- Materia
- Cuore
- Copen
One thing to check: some older Daihatsus (e.g. early Sirion/Terios) ask for a shorter 4-character code instead. That is a different, older system and is not covered by this lookup. If yours shows 16 hexadecimal characters, you are in the right place. Driving a Toyota? See our Toyota radio code page, same ERC system.
Frequently asked questions
ERC: The 16-character code on your locked radio's display. You give us this.
Unlock code: The 4-digit PIN you type into the radio to unlock it. We give you this after payment.
Give us the ERC, we work out the unlock code, you enter that into the radio to get sound back.
Yes, though it takes longer. Daihatsu/Toyota dealers can issue a code once you prove ownership with your V5C and photo ID. Typically:
- several working days turnaround
- An in-person visit is required
- Some dealers charge a fee
Our £4.99 lookup is instant and available online 24/7.
Copy-paste if you can, it avoids transcription mistakes entirely. A single mistyped character will send back the wrong result.
If you're typing it manually, go slowly and double-check lookalike characters like 0/O and 1/I.
We guarantee every code 100%. If it doesn't unlock your radio, contact us and we'll refund you in full, no questions asked.
Before trying it, just confirm you copied the ERC correctly from the display.
We only retain what's needed to process your order. We don't store your ERC or vehicle details longer than necessary, we never see your card details (Stripe handles payment), and we never sell or share your data.
