How to Use the OBDSTAR X300 DP Plus PIN Code Check Function

For automotive locksmiths and workshop technicians, retrieving the correct PIN code is often the most critical and time-consuming step in key programming. Many modern vehicles require a security PIN to authorize immobilizer functions, and not all diagnostic tools offer a straightforward way to obtain this code. The Obdstar X300 DP Plus (also known as the Key Master DP Plus) addresses this challenge with its dedicated PIN code check function – a feature designed to simplify the process for select manufacturers, including Nissan and Infiniti. This guide explains exactly how to use this function, what to expect, and why it is a valuable addition to your toolset.

Why a Dedicated PIN Code Check Function Matters

While the OBDSTAR X300 DP Plus supports one-click free key programming for many vehicle models, there are still partial manufacturers where this direct approach is not yet available. In these cases, the PIN code remains a barrier. The check pincode function was developed specifically to bridge this gap, giving locksmiths a reliable, on-demand method to retrieve the necessary security codes without relying on external databases or dealership visits. This not only saves time but also reduces the operational costs associated with PIN code retrieval services.

Supported Vehicles and Prerequisites

The PIN code check function is currently available for select Nissan and Infiniti models. Before you begin, ensure that your OBDSTAR X300 DP Plus (or X300 PRO4 Key Master) is updated to the latest firmware version. You will also need a stable internet connection, as the function communicates with OBDSTAR servers to process the request. Additionally, be aware that each PIN code check consumes 8 credits from your device account – a small investment for the convenience and accuracy it provides.

Step-by-Step Guide: Checking a PIN Code with OBDSTAR X300 DP Plus

The following steps walk you through a typical PIN code check procedure using a Nissan Kicks as an example. The workflow is intuitive and can be adapted to other supported models.

Step 1: Connect and Navigate to the PIN Code Menu

Connect your OBDSTAR X300 DP Plus to the vehicle’s OBD-II port and power on the device. From the main screen, enter the CAR IMMO function. Once inside, locate and tap the [PINCODE] option to access the PIN code retrieval module.

Step 2: Select the Correct Vehicle and PIN Code Edition

Choose the newest PIN code edition available in the software. Then, navigate to [NISSAN/INFINITI] and select [20 DIGIT PINCODE] followed by your specific model – for example, [KICKS]. This ensures that the tool uses the correct algorithm for your vehicle.

Step 3: Enter the 20-Digit ID Code

After confirming the model, the device will prompt you to enter a 20-digit ID code. This code is read out by the device from other manufacturer tools or diagnostic sessions. A critical note: although the ID code displayed may contain 22 digits, you should only input the first 20 digits – entering the full 22 digits will result in an error. Double-check your entry before confirming.

Step 4: Confirm and Complete the Check

Once you have entered the 20-digit ID code, confirm it by tapping [Enter]. The device will then process the request, deduct 8 credits from your account, and display the result. If successful, you will see a message confirming that the rolling code has been read out successfully. At this point, the PIN code is available for use in your key programming session.

Important Notes and Best Practices

• Credit Management: Each PIN code check consumes 8 credits. Ensure you have sufficient credit balance before starting the procedure to avoid interruptions.
• ID Code Format: Pay close attention to the ID code length – only the first 20 digits are required, even if the source displays 22.
• Follow On-Screen Prompts: The OBDSTAR X300 DP Plus provides clear, step-by-step instructions throughout the process. Always follow the device tips exactly as they appear to ensure a smooth operation.
• Compatibility: While this guide uses Nissan/Infiniti as an example, always check the latest software update notes for newly added models and PIN code editions.
