Which radio is in your Toyota Corolla?
Toyota fitted different radios over the years. Find your Corolla’s years below, but go by the serial: radios are often swapped, and the free check reads it for you.
How to find your Toyota Corolla radio serial number
Most Toyota Corolla 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.
Tips for your Toyota Corolla
- Try it first. A Corolla radio that has lost power very often just plays.
- If it asks, hold buttons 1 and 6 for the ERC.

How to enter your Toyota Corolla 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 Toyota Corolla 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 Toyota Corolla’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.
Toyota Corolla radio code questions
My Corolla is a 2003 and the radio wants a code.
Hold buttons 1 and 6 and see whether an ERC appears. Older Corollas mostly are not locked, so if nothing comes up it may be a fault rather than a code.
Is the Corolla the same as the Auris?
For radios, from 2006 onwards effectively yes — the same units and the same ERC scheme, whichever badge is on the back.
How much is a Toyota Corolla 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 Toyota Corolla 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.
