Introduction

This tutorial provides a step-by-step guide on how to reset or remove a BIOS password using the Master Code method. This process is applicable to various PC manufacturers, including ASUS, Lenovo, Acer, Sony, HP, and Dell. By following the instructions below, you will learn how to access your BIOS without the password, ensuring that you can make necessary changes to your system.

Step 1: Gather Necessary Tools

Before you start, ensure you have the following tools ready:

• A computer with internet access
• Python 2.6 installed on your machine (download from Python 2.6 releases)
• Access to a secondary device to look up your Master Code if needed

Step 2: Identify Your BIOS Password Lock

1. Turn on your computer and enter the BIOS setup. This is usually done by pressing a specific key during startup, like F2, DEL, or ESC, depending on the manufacturer.
2. If prompted for a password, note down the error message displayed; this often includes a numeric code that can be used to generate the Master Code.

Step 3: Generate the Master Code

You can generate the Master Code using one of the following methods:

Method 1: Online Master Code Generator

• Visit bios-pw.org.
• Input the numeric code obtained from the BIOS error message.
• The site will generate the Master Code for you.

Method 2: Using Python Scripts

If you prefer a more hands-on approach, you can use Python scripts to calculate the Master Code.

1. Visit Dogber1’s Blog for scripts.
2. Follow the instructions provided to run the script. Here’s a basic example of what the script might look like:

# Example Python script snippet
def calculate_master_code(lock_code):
    # Logic to calculate master code goes here
    return master_code

Replace lock_code with the numeric code you noted earlier.

Step 4: Access BIOS Using Master Code

1. Restart your computer and return to the BIOS setup.
2. When prompted for the password, enter the Master Code you generated.
3. If successful, you will gain access to the BIOS settings.

Step 5: Reset or Remove the BIOS Password

1. Navigate to the security settings within the BIOS.
2. Look for the option to change or remove the password.
3. Follow the on-screen instructions to reset or clear the password.
