No, unlike some other radio codes offered on this website, we do not offer free Honda radio codes at this time.

We generally deliver within the hour via email, however if there is a delay we will get in touch and let you know.

Yes, we guarantee all unlock codes we deliver, all that we ask is if your code does not work, send us a video of it being entered into the radio unit, once we have confirmed this, we will refund your order.

When “Err” appears on your radio screen, it is because of a failed code entry attempt. You can have another go at entering your code by switching the radio off and back on, but be careful because if you enter too many incorrect codes, the unit may become permanently locked and you will need the dealership to fix it.
