A keyless entry remote is a lifesaver, isn’t it? Just a click and your car doors unlock. But what happens when it stops working? You’ll likely need a scanning tool to reprogram it. This article dives into what these tools are, how they work, and what to consider when choosing one.
Understanding Keyless Entry and Reprogramming
Keyless entry systems use radio frequencies to communicate between your remote and your car. When you press a button, the remote sends a unique coded signal. If the car recognizes the code, the doors unlock. Reprogramming involves teaching your car to recognize a new code from your remote, or vice-versa. This is where the scanning tool comes in.
What is a Scanning Tool to Reprogram a Keyless Entry Remote?
A scanning tool, in this context, is an electronic device that interfaces with your car’s onboard computer. It acts as a bridge, allowing you to access and modify the settings related to your keyless entry system. These tools can read diagnostic trouble codes, program new remotes, and even perform more complex functions like programming immobilizer systems.
Different Types of Scanning Tools
There are various types of scanning tools available, from basic code readers to professional-grade diagnostic platforms.
- Basic Code Readers: These are the most affordable option and can read and clear basic diagnostic trouble codes. However, they typically lack the capability to reprogram keyless entry remotes.
- Enhanced Code Readers: These offer more features than basic code readers, including some key fob programming capabilities, but their functionality might be limited to specific car makes and models.
- Professional Diagnostic Scanners: These are the most powerful and versatile tools used by professional mechanics. They offer comprehensive diagnostic and programming functions, including keyless entry reprogramming for a wide range of vehicles.

How to Use a Scanning Tool to Reprogram a Keyless Entry Remote
The specific steps for reprogramming a keyless entry remote vary depending on the car make, model, and the scanning tool being used. However, the general process involves connecting the scanning tool to the car’s OBD-II port, accessing the keyless entry system menu, and following the on-screen prompts to program the remote.
- Connect the scanner: Locate the OBD-II port, usually under the dashboard on the driver’s side, and connect the scanning tool.
- Turn the ignition on: Turn the key to the “on” position without starting the engine.
- Access the keyless entry menu: Navigate through the scanning tool’s menu to find the keyless entry or remote programming function.
- Follow the prompts: The tool will guide you through the programming process, which usually involves entering a specific code or performing a sequence of actions with the remote and the car’s ignition.
Choosing the Right Scanning Tool
Selecting the right scanning tool depends on your needs and budget. If you’re a car owner who occasionally needs to reprogram a remote, an enhanced code reader might suffice. However, for professional mechanics or car enthusiasts working on multiple vehicles, a professional diagnostic scanner is a worthwhile investment.
Factors to Consider
- Vehicle Compatibility: Ensure the tool is compatible with the make and model of your car.
- Functionality: Determine the features you need, such as code reading, key programming, and other diagnostic capabilities.
- User-Friendliness: Choose a tool with an intuitive interface and easy-to-understand instructions.
- Budget: Scanning tools range in price from affordable to quite expensive. Set a budget before you start shopping.
