About Lexus radio codes
Lexus owners in the UK rarely need a radio code: after a flat battery the system normally comes back by itself. The cars that do ask are usually imports with a Japanese navigation radio, which shows a 16-character code called the ERC. We turn that into your unlock code straight away.
How to find your Lexus radio serial number
Most Lexus radios show their serial on the screen, so you don’t need to take anything apart. The serial tells us exactly which code your radio needs.
On the screen
- Check first that the radio really wants a code: most Toyotas sold in the UK come back on by themselves.
- Hold the main button on the screen and switch the parking lights on and off 3 or 4 times, until a new screen appears.
- Press the one button on that screen. Write down the 16 letters and numbers it shows: that is the ERC.
On the label
The serial is also printed on a label on the top or side of the radio. Most radios slide out with a pair of radio removal keys (a few pounds from any car parts shop). Push them into the slots on the front until they click, then ease the radio forward. Some have screws to undo first.
Photograph the label rather than copying it by hand — 0 and O, 1 and I are easy to mix up.

How to enter your Lexus radio code
Once you have your code, key it in like this. Your order page shows the same steps next to your code.
Toyota / Lexus ERC
- Type in your 8-character code exactly, with the numbered buttons or the touchscreen.
If your Lexus radio says LOCKED, WAIT or SAFE
Each wrong code makes the radio wait longer before the next try, and some radios lock for good after too many. Don’t guess: get the right code first, then follow the steps for your radio.

Why we use your radio’s serial, not your number plate
A radio code belongs to the radio, not the car. A dealer usually looks it up from the Lexus’s number plate or VIN (the 17-character number in your logbook), which only works if the car still has the radio it left the factory with. Radios are often swapped under warranty, upgraded, or changed by a previous owner.
The serial is printed on the radio itself, so the code matches the radio in front of you. It is also what lets us check for free before you pay. Main dealers often charge £30–£130, and you usually have to book the car in.

Lexus radio code questions
Does my Lexus need a radio code?
Usually not. Owners report that UK cars come back on their own after the battery has been off.
How do I get the ERC?
On a Japanese navigation radio: hold the main button on the screen and switch the parking lights on and off three or four times until a hidden screen appears, then press the one button on it. Sixteen letters and numbers is the ERC.
How much is a Lexus radio code?
£9.99 per code. The free check comes first, so you only pay once we know we can do it, and you get your money back if the code doesn’t work.
How long does it take?
Most Lexus codes appear on screen the moment you’ve paid, and we email you a copy. If yours has to be looked up by our team, we email it within 2 hours and tell you before you pay.
What if the code doesn’t work?
Check the serial first: 0 and O, or 1 and I, are easy to mix up. Still stuck? Tell us from your order page and we’ll put it right or refund you in full.
