2009 GMC Sierra Key Fob Programming: A Comprehensive Guide

1. Understanding Your 2009 GMC Sierra Key Fob

The key fob for your 2009 GMC Sierra isn’t just a convenient way to lock and unlock your doors. It’s an integral part of your vehicle’s security system. A properly programmed key fob allows you to remotely control door locks, activate the panic alarm, and even start the engine on some models. Understanding its functionalities is the first step in ensuring seamless operation.

1.1 Key Fob Components and Functions

Your GMC Sierra key fob typically includes buttons for:

• Lock: Secures all doors.
• Unlock: Unlocks the driver’s side door (or all doors, depending on your vehicle’s settings).
• Panic: Activates the horn and exterior lights as an emergency alert.
• Remote Start (if equipped): Starts the engine remotely.
• Rear gate (if equipped): Opens the rear gate

1.2 Importance of Proper Programming

Proper key fob programming is crucial for several reasons:

• Security: A correctly programmed fob prevents unauthorized access to your vehicle.
• Convenience: Remote functions save time and effort.
• Functionality: Ensures all features, such as remote start, operate correctly.

2. Preparing for Key Fob Programming

Before diving into the programming process, gather necessary information and tools, and ensure your vehicle is ready.

2.1 Gathering Necessary Information

• Vehicle Identification Number (VIN): Located on the driver’s side dashboard or door jamb. This is important if you need a replacement key fob.
• Owner’s Manual: Consult your owner’s manual for specific programming instructions and details about your vehicle’s features.
• Replacement Key Fob: Purchase a compatible key fob from a reputable source like CARDIAGTECH.NET. Ensure it matches the original fob’s part number. The part number for the key fob discussed here is 15913421.

2.2 Ensuring Vehicle Readiness

• Battery Condition: Ensure your GMC Sierra’s battery is fully charged. Low battery power can interfere with the programming process.
• Location: Park your vehicle in a safe, well-lit area.
• Original Key Fobs: Have all original key fobs that you want to program available during the process, as you may need to program them all at once.

2.3 Understanding Driver Information Center (DIC)

Some 2009 GMC Sierra models have a Driver Information Center (DIC) with buttons on the steering wheel. Other models may not. The method you use for programming your key fob depends on whether your vehicle has a DIC.

• With DIC: Vehicles equipped with DIC will have buttons on the steering wheel with an “i” symbol. This allows you to navigate to the “Relearn Remote Key” function through the DIC menu.
• Without DIC: Vehicles without the DIC require using the trip odometer reset button to access the programming mode.

3. Key Fob Programming Procedures

Follow the appropriate procedure based on whether your 2009 GMC Sierra has a Driver Information Center (DIC).

3.1 Procedure #1: Vehicles with Driver Information Center (DIC)

1. Insert and Turn the Key: Insert the key into the ignition and turn it to the “On” position. Do not start the engine.
2. Navigate to Relearn Remote Key: Press the Information button (usually marked with an “i” symbol) on the steering wheel until “Relearn Remote Key” is displayed on the DIC screen.
3. Activate Remote Key Learning: Press the set/reset button (often has a checkmark symbol) until “Remote Key Learning Active” is displayed. The vehicle is now in programming mode.
4. Program the Key Fob: Press and hold both the Lock and Unlock buttons on the key fob simultaneously until the vehicle chimes twice. This indicates successful programming of that fob.
5. Repeat for Additional Fobs: Repeat step 4 for any additional new or existing key fobs you want to program. It’s essential to program all fobs at the same time to ensure they all work with the vehicle.
6. Exit Programming Mode: Turn the key to the “Off” position. This will exit the programming mode. Test all programmed key fobs to ensure they function correctly.

3.2 Procedure #2: Vehicles without Driver Information Center (DIC)

1. Insert and Turn the Key: Insert the key into the ignition and turn it to the “On” position. Do not start the engine.
2. Access Relearn Remote Key: Press the trip odometer reset button repeatedly until “Relearn Remote Key” is displayed on the instrument panel.
3. Activate Remote Key Learning: Press and hold the trip odometer reset button until “Remote Key Learning Active” is displayed. The vehicle is now ready to program.
4. Program the Key Fob: Hold the Lock and Unlock buttons on the key fob being programmed simultaneously until the vehicle chimes. This confirms the fob has been successfully programmed.
5. Repeat for Additional Fobs: Repeat step 4 for any additional new and existing key fobs you wish to program. Ensure all fobs are programmed during the same session.
6. Exit Programming Mode: Turn the key to the “Off” position to exit the programming mode. Test all key fobs to verify they are working correctly.

3.3 Important Notes

• Programming All Remotes: If any of your remotes stop working after programming, you must reprogram all remotes in the same session.
• Chime Confirmation: The chime is crucial, as it confirms that the vehicle has recognized the key fob’s signal.
• Timing: Perform each step promptly, as the system may time out if there are delays.

4. Troubleshooting Common Issues

Key fob programming doesn’t always go as planned. Here are some common issues and how to troubleshoot them.

4.1 Key Fob Not Responding

• Battery Check: The most common issue is a dead or weak battery in the key fob. Replace the battery with a new one and try the programming procedure again.
• Incorrect Procedure: Double-check that you are following the correct programming procedure for your vehicle model (with or without DIC).
• Signal Interference: Move away from potential sources of radio frequency interference, such as cell towers or other electronic devices.
• Faulty Key Fob: The key fob itself may be defective. Try programming a different key fob to rule out this possibility. You can get a new one from CARDIAGTECH.NET.

4.2 Vehicle Not Entering Programming Mode

• Ignition Position: Ensure the key is in the correct “On” position, but the engine is not started.
• Door Ajar: Make sure all doors, the hood, and the trunk are fully closed.
• Security System Issues: If your vehicle’s security system is malfunctioning, it may prevent you from entering programming mode. Consult a professional technician.

4.3 Key Fob Programs but Doesn’t Work

• Incorrect Key Fob: Verify that the key fob is compatible with your 2009 GMC Sierra.
• Programming Error: Repeat the programming procedure carefully, ensuring each step is followed precisely.
• Vehicle Memory Full: In some cases, the vehicle’s memory for key fobs may be full. You may need a professional to clear the memory.

5. When to Seek Professional Help
