Why is my Toyota Prius radio locked after a battery change?

This is a very common issue with Toyota Prius models, particularly Japanese imports. When the 12V auxiliary battery is replaced, disconnected, or drains completely, the navigation unit's anti-theft system activates automatically. To protect against theft, the radio locks itself and requires a specific 16-digit ERC unlock code to function again. We can generate this code for you instantly using your radio's serial number.

Which Toyota Prius models and years do you support?

We support radio unlocking for all Toyota Prius generations, including the Prius Gen 2 (NHW20), Gen 3 (ZVW30), Gen 4 (ZVW50), and Prius Alpha/v (ZVW40/41). This includes plug-in hybrids (PHV/Prime) and import models equipped with Japanese navigation systems like the NSZT-W68T, NSZT-Y66T, NSZN-Z68T, NHZD-W62G, NHDT-W59G and older HDD units.

Is the Prius radio unlock code permanent?

Yes, the unlock is permanent. Once you enter the ERC unlock code we provide, your radio will function normally. If your 12V battery needs to be replaced again in the future, you can simply reuse the same code to unlock the radio without paying again. We suggest keeping a copy of the code in your glovebox or phone for future use.

How do I find the ERC Number on my Prius navigation unit?

You don't need to take the dashboard apart. For most Prius navigation units, simply press and hold the "Audio" or "Menu" button on the unit while turning your parking lights (headlights) on and off 3 times rapidly. This will trigger a hidden service menu on the screen. Select the button that says "Service Info" (or similar) to view your 16-digit ERC serial number.

How long does it take to get my Prius radio unlock code?

Our system provides instant results. Immediately after your payment is processed, your unique Toyota Prius unlock code is displayed on the screen and sent to your email address. You can have your audio, reversing camera, and Bluetooth working again in minutes.

What if the code doesn't work on my Prius?

We offer a 100% money-back guarantee. If the code we generate does not work for the specific ERC serial number you submitted, we will provide a full and immediate refund. Our service is risk-free and has helped thousands of Prius owners worldwide.

Take a Photo: When you see the 16-character code, take a clear photo. Keep the ignition on so the code doesn’t change.
