**2017 GMC Sierra Key Programming: Your Comprehensive Guide**

Programming a new key for your 2017 GMC Sierra can seem daunting, but with the right information and tools, it’s a manageable task. This guide, brought to you by CARDIAGTECH.NET, provides a detailed walkthrough of the process, ensuring you can get back on the road quickly and securely. Whether you’re adding a spare key or replacing a lost one, understanding the key programming process is crucial for any 2017 GMC Sierra owner.

1. Understanding Your 2017 GMC Sierra Key

Before diving into the programming process, it’s essential to understand the type of key your 2017 GMC Sierra uses. Most models come equipped with a transponder key, which contains a microchip that communicates with the vehicle’s immobilizer system. This system prevents the car from starting unless the correct key is present.

1.1. Transponder Keys Explained

Transponder keys have been a standard security feature in vehicles since the mid-1990s. According to a study by the National Highway Traffic Safety Administration (NHTSA), vehicles with immobilizer systems, like those using transponder keys, experience significantly lower rates of theft. These keys work by sending a unique signal to the car’s computer, which then authorizes the ignition. If the signal doesn’t match, the car won’t start, providing an effective layer of security against unauthorized access.

1.2. Key Components

A typical transponder key for a 2017 GMC Sierra consists of:

• Key Blade: The physical metal part that is cut to match your vehicle’s ignition cylinder.
• Transponder Chip: A small microchip embedded in the plastic head of the key.
• Remote Buttons (Optional): Some keys include buttons for remote locking, unlocking, and other functions.

1.3. Identifying the Correct Key Blank

Using the correct key blank is crucial for successful programming. For a 2017 GMC Sierra, the appropriate key blank is often a B119-PT or equivalent. Here’s a list of compatible aftermarket replacements:

• Strattec: 7013237, 5927933, 5927928, 5924205, 5924206, 5928092
• OEM: 23209427, 22984996, 23286589, 23286588, 23326748
• Hata: 2428
• Ilco: B119-PT, B119 PT, B116-PT, B116 PT, B119 PT, B116-PT, B116 PT
• Test Key: HU100

2. Key Programming Methods for Your 2017 GMC Sierra

There are two primary methods for programming a key for your 2017 GMC Sierra: using an existing working key and using specialized programming equipment. Each method has its own requirements and steps.

2.1. Programming with an Existing Working Key

If you have at least one working key, you can program additional keys yourself using the vehicle’s built-in programming mode. This method is convenient and doesn’t require any special tools.

2.1.1. Step-by-Step Instructions

1. Insert the Working Key: Place the existing, programmed key into the ignition cylinder.
2. Turn to the ON Position: Turn the ignition to the “ON” position for 5 seconds. The engine should not start.
3. Turn to the OFF Position: Turn the ignition back to the “OFF” position and remove the key.
4. Insert the New Key: Within 5 seconds, insert the new, unprogrammed key into the ignition cylinder.
5. Turn to the ON Position Again: Turn the ignition to the “ON” position for 5 seconds.
6. Turn to the OFF Position: Turn the ignition back to the “OFF” position.
7. Test the Key: Remove the new key and try starting the vehicle. If the programming was successful, the engine should start.

2.1.2. Troubleshooting

If the key doesn’t program correctly on the first try, repeat the steps. Ensure that you are inserting the keys quickly and accurately. If you continue to have issues, the key may not be compatible, or there may be an issue with the vehicle’s immobilizer system.

2.2. Programming Without an Existing Key

If you’ve lost all your keys, you’ll need to use a specialized programming tool or visit a professional locksmith or dealership. This method involves accessing the vehicle’s computer system to bypass the immobilizer and program a new key.

2.2.1. Using a Programming Tool

Professional automotive locksmiths and dealerships use diagnostic tools to program new keys when no existing key is available. These tools connect to the vehicle’s OBD-II port and allow them to communicate with the car’s computer.

1. Connect the Tool: Plug the programming tool into the OBD-II port, typically located under the dashboard.
2. Follow On-Screen Instructions: The tool will provide step-by-step instructions for programming the new key. This usually involves entering a security code or PIN, which can be obtained from the vehicle’s manufacturer or a locksmith.
3. Program the Key: Follow the tool’s instructions to program the new key. This may involve turning the ignition on and off several times or waiting for a specific period.
4. Test the Key: Once the programming is complete, test the new key to ensure it starts the vehicle.

2.2.2. Visiting a Locksmith or Dealership

If you don’t have access to a programming tool, the easiest option is to visit a professional locksmith or dealership. They have the necessary equipment and expertise to program a new key for your 2017 GMC Sierra.

• Locksmith: Automotive locksmiths often provide mobile services, meaning they can come to your location to program a new key. This can be more convenient than towing your vehicle to a dealership.
• Dealership: Dealerships have specialized equipment and access to manufacturer databases, ensuring they can program a key even if you’ve lost all your keys.

3. Common Issues and Troubleshooting Tips

Key programming isn’t always straightforward. Here are some common issues you might encounter and how to troubleshoot them.

3.1. Key Not Recognized

If the vehicle doesn’t recognize the new key, it could be due to several reasons:

• Incorrect Key Blank: Ensure you are using the correct key blank for your 2017 GMC Sierra.
• Faulty Transponder Chip: The transponder chip in the key may be damaged or defective.
• Improper Programming: The programming process may not have been completed correctly.
• Vehicle Immobilizer Issues: There may be a problem with the vehicle’s immobilizer system.

Troubleshooting Steps:

1. Verify Key Compatibility: Double-check that the key blank is compatible with your vehicle.
2. Inspect the Key: Look for any signs of damage to the key or transponder chip.
3. Repeat Programming: Try repeating the programming process carefully, following each step precisely.
4. Seek Professional Help: If the issue persists, consult a locksmith or dealership for further diagnosis.

3.2. Security Light Stays On

If the security light on the dashboard remains illuminated after programming, it indicates that the vehicle is not recognizing the key.

Troubleshooting Steps:

1. Wait and Retry: Sometimes, the security system needs time to reset. Wait for a few minutes and then try starting the vehicle again.
2. Check Battery Voltage: Low battery voltage can sometimes interfere with the programming process. Ensure your vehicle’s battery is fully charged.
3. Consult a Professional: If the security light remains on, there may be an issue with the vehicle’s security system that requires professional attention.

3.3. Key Cuts but Won’t Start the Car

If the key is correctly cut but the car won’t start, it means the transponder chip has not been properly programmed.

Troubleshooting Steps:

1. Ensure Programming: Follow the programming steps outlined earlier in this guide to program the transponder chip.
2. Check Chip Placement: Make sure the transponder chip is securely seated within the key’s plastic head.
3. Seek Professional Programming: If you’re unable to program the chip yourself, visit a locksmith or dealership for professional programming services.

4. The Importance of Professional Key Programming

While it’s possible to program a key for your 2017 GMC Sierra yourself, there are several benefits to seeking professional assistance.

4.1. Expertise and Equipment

Professional locksmiths and dealerships have the expertise and specialized equipment necessary to program keys accurately and efficiently. They can diagnose and resolve any issues that may arise during the programming process.

4.2. Security and Reliability

Professionals ensure that the new key is securely programmed and functions reliably with your vehicle’s security system. They can also provide guidance on maintaining your keys and preventing future issues.

4.3. Cost-Effectiveness

While professional key programming may involve an upfront cost, it can be more cost-effective in the long run. Attempting to program a key yourself without the proper knowledge or equipment can lead to mistakes that could damage your vehicle’s security system, resulting in more expensive repairs.

5. Cost of 2017 GMC Sierra Key Programming

The cost of programming a key for your 2017 GMC Sierra can vary depending on several factors, including the type of key, the programming method, and the service provider.
