Which Lexus models do you support?

We support Lexus CT, IS, GS, LS, ES, RC, RX, NX, UX, LX and GX fitted with factory ERC radios.

ERC stands for Electron Radios Code, the anti-theft system Lexus shares with parent company Toyota. It's a 16-character hexadecimal code (0–9, A–F) unique to your radio and vehicle.

How do I find my Lexus ERC code?

Turn the ignition on without starting the engine. The display shows 'LOCKED', and your 16-character ERC appears beneath it (e.g. 1A2B3C4D5E6F7A8B). Write it down carefully, character for character.

Why does Lexus use the same system as Toyota?

Lexus is Toyota's luxury division, and both brands use the same ERC anti-theft radio system across their model ranges. The format, the display behaviour, and the code lookup process are identical.

Do I need to remove the radio?

No. The ERC code shows on the radio's locked display. There's no need to remove anything to read it.

Do you support aftermarket Lexus radios?

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

Frequently asked questions

What's the difference between the ERC and the unlock code? +

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.

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

Yes, though it takes longer. Lexus 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.

Should I type the ERC or copy-paste it? +

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.

What if the unlock code doesn't work? +

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.

Do you keep my ERC on file? +

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.
