  • Steps For Resetting The Radio: Using Codes

                    – With A Code

                    – Without A Code

  • Wiping Your Data: Why It Is Necessary?

Now, let us dive into the process. 

There are essentially two ways you can reset the radio – by using codes or without using the codes. We will explain both ways of resetting. 

1. Resetting With A Code

Here is how you can do so:

  • Turn the car’s ignition on. That way, the radio will start getting the power supply from the battery. You do not have to start the engine necessarily. 
  • Check if the radio is on. If not, press the radio’s power button to turn it on. 
  • While you do so, press the up arrow and “1” button simultaneously. 
  • Once you press all the mentioned keys simultaneously, you will see four dashes appear on display. 
  • In those dashes, enter the code. If your Toyota radio has a security code, you must enter it to reset it. The code should be in your owner’s manual, or you may be able to retrieve it from a Toyota dealership. Use the radio preset buttons to enter the code, then press the “Enter” or “OK” button.
  • Your radio will reset. 

2. Resetting Without A Code

Sometimes, you may have lost your code or cannot use it for some reason. You can reset the system even without the security code. Here is what you can do:

  • Turn the car’s ignition on. That way, the radio will start getting the power supply from the battery. You do not have to start the engine necessarily.  
  • When the display appears with the four dashes, turn your radio off. 
  • Now, the arrow-pointing down button should be held. Hold it and the power button together while holding for roughly a minute. 
  • The radio should start resetting.

Wipe Your Data: Why Is It Necessary?

Resetting the radio after a battery change is essential because many car radios have a security feature that prevents them from being used if they are removed from the car or if the battery is disconnected. This security feature is designed to deter theft and protect the owner’s assets. 

When the power is disconnected from the radio, a security code will be entered before it can be used again. This is to ensure that the radio cannot be used by someone who does not have the code.

Resetting the radio is also essential to restore it to its default settings, which may have been lost during the battery change. This includes things like a clock; radio presets, and any other previously programmed settings.

Also, in case you are selling your Toyota radio, resetting your radio is essential as your saved data can get into someone else’s hands. Also, the buyer can use it freshly according to their needs. 

Frequently Asked Questions 

1. Will disconnecting the battery reset my radio?

Yes, disconnecting the battery can reset your car radio.

Disconnecting the battery can cause the radio to lose its memory settings, such as the radio station presets and the clock time. This is why resetting the radio after changing the battery is essential.

2. Do I need to reset the car radio after changing the battery?

Yes. After changing the battery, your car radio may need to be reset. The radio may lose its memory settings, including the preset radio stations and the time if the battery is disconnected. You’ll need to reset your car radio to get these settings back. 

3. Does the car battery affect the radio?

Radio gets power directly from the car’s battery. Without it, it isn’t easy to work as it relies on the electrical system to function properly. If the battery is weak or not functioning properly, it can cause issues with the radio. 

4. Can every Toyota radio fit in other brand cars?

No, not every Toyota radio will fit in other brand cars. Car radios are designed to fit specific makes and models of vehicles, and they may not be interchangeable between different brands.

In addition to the physical dimensions of the radio, the wiring, and electrical connections may also be different between different brands of cars. This means that even if a Toyota radio physically fits in another car brand, it may not function properly or require modifications to the wiring or electrical connections.

5. How much power does a car stereo system use?

The amount of power a car stereo system uses can vary depending on several factors, such as the type and size of the speakers, the amplifier’s power rating, and the volume level at which the system is playing.

Depending on the music’s volume, a simple car stereo system with four speakers and no amplifiers can often use between ten and fifty watts of power. On the other hand, a premium automobile stereo setup with more speakers, subwoofers, and a robust amplifier can use hundreds or even thousands of watts.

6. What brand of stereo does Toyota use?

Toyota uses a variety of stereo brands for its factory-installed audio systems, depending on the specific make and model of the vehicle and the year it was produced. Some of the most commonly used brands for Toyota’s factory-installed audio systems include JBL, Pioneer, and Entune.

They use high-quality music systems with sophisticated features and excellent audio quality. 


So, you can reset your Toyota radio after the battery change. You can do so by using a security code or without one, and you can even consult your dealership for the same. 

If any other problem arises, visit the dealership. For more information, check out our guide on how to unlock a car radio without the code.
