Which radio is in your Toyota ERC Units?
Toyota fitted different radios over the years. Find your ERC Units’s years below, but go by the serial: radios are often swapped, and the free check reads it for you.
What is printed on the label
People look these up because they are the only numbers on the radio that mean anything. A part number identifies the unit and is the same on every one ever built; the serial is yours alone and is the one we need. They are easy to mix up, so here is what to expect on a Toyota ERC Units.
| Printed on the unit | What it is |
|---|---|
| 30069920ECF1F3AC | The ERC string. Sixteen characters, and the whole of what we need. |
| A Toyota part number | Printed alongside, and shared across the model. Not a serial. |
A part number on its own cannot produce a code — every radio of that model shares it. If the number you have is one of the part numbers above, keep looking for the serial: it is the longer one, and usually on a separate line or a barcode label.
How to find your Toyota ERC Units radio serial number
Most Toyota ERC Units 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.
Take a photo of the label rather than copying it by hand: it’s easy to mix up 0 and O, or 1 and I.
Tips for your Toyota ERC Units
- The ERC is usually reached through the unit’s own diagnostic screen rather than a label.
- Sixteen characters is a lot to copy by eye. Photograph it if you can.

If your Toyota ERC Units 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.
| Radio | What to do |
|---|---|
| Toyota / Lexus ERC | The ERC changes if the battery is disconnected again. Check the new one for free. |

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 ERC Units’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 number is printed on the radio itself, so the code we give you matches the radio in front of you. It is also how we can check it for free before you pay. Main dealers often charge £30–£130, and you usually have to book the car in.
Toyota ERC Units radio code questions
What is an ERC?
Encrypted Radio Code — the scheme Toyota and Lexus used. The sixteen-character string it shows is what the code is worked out from.
Does my Toyota even need a code?
Plenty do not. Many Toyotas simply come back on after a battery change with nothing but the clock to reset.
How much is a Toyota ERC Units 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 ERC Units 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.
