• Your 2020 GMC Yukon: The vehicle you want to program the key fob for.
• The Key Fob to Be Programmed: Ensure it is compatible with your vehicle.
• Working Key Fobs (If Applicable): Depending on the programming method, you may need one or two working key fobs.
• Vehicle Owner’s Manual: Consult your manual for specific instructions and details.

2.1. Checking Key Fob Compatibility

Ensuring key fob compatibility is essential. Refer to your vehicle’s owner manual or consult with a local automotive locksmith or dealer to verify that the key fob you intend to program is the correct one for your 2020 GMC Yukon. Using an incompatible key fob can lead to programming failures or even damage to your vehicle’s system.

2.2. Gathering Necessary Tools

While most 2020 GMC Yukon key fob programming methods don’t require special tools, having a small screwdriver to open the key fob’s battery compartment might be helpful. Ensure you have a new, compatible battery for the key fob, as a low battery can sometimes cause programming issues.

3. Step-by-Step Guide to 2020 GMC Yukon Key Fob Programming

The 2020 GMC Yukon offers a few methods for key fob programming, depending on whether you have existing working key fobs. Here’s a detailed guide for each scenario:

3.1. Programming with Two Working Smart Keys

This method is the simplest and fastest if you have two functioning smart keys.

1. Prepare the Vehicle: Ensure the vehicle is turned off, and all doors are closed. Have all the smart keys, both working and new, with you.
2. Remove the Emergency Key Blade: Take out the emergency key blade from one of the working smart keys.
3. Place Working Keys in the Cupholder: Put the two working smart keys in the cupholder.
4. Insert and Turn the Emergency Key Blade: Insert the emergency key blade into the driver’s door lock cylinder. Turn the key counterclockwise to the unlock position five times within 10 seconds. Note: Some vehicles may require removing the lock cylinder cap on the driver’s door handle to access the door lock.
5. Wait for DIC Display: The Driver Information Center (DIC) will display READY FOR REMOTE # 2, 3, 4, etc.
6. Place the New Smart Key: Place the new smart key into the transmitter pocket. For Cadillac vehicles, this is inside the center console storage area between the driver and front passenger seats. For Chevrolet, GMC, and Buick vehicles, it’s in the front cupholder.
7. Press the ENGINE START/STOP Button: Press the ENGINE START/STOP button. When the new smart key is recognized, the DIC display will show that it is ready to program the next smart key.
8. Remove and Test: Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the remote to test.
9. Program Additional Smart Keys: To program additional smart keys, repeat Steps 6-8.
10. Exit Programming Mode: When all additional smart keys are programmed, press and hold the ENGINE START/STOP button for approximately 12 seconds to exit the programming mode.

3.2. Programming Without Two Working Smart Keys

If you have only one working smart key or none, this method will take approximately 30 minutes to complete. DIY programming is not available in Canada.

1. Prepare the Vehicle: Ensure the vehicle is off and that all smart keys, both currently working and new, are with you. Read and understand the entire procedure before you begin.
2. Remove the Key Blade: Remove the key blade from your existing or new smart key. If you have no smart keys, get the emergency key blade in your new smart key cut by a locksmith before proceeding.
3. Insert and Turn the Emergency Key Blade: Insert the emergency key blade into the driver’s door lock cylinder, then turn the key counterclockwise to the unlock position five times within 10 seconds. (On some vehicles, you will need to remove the lock cylinder cap on the driver’s door handle to access the door lock.) The Driver Information Center (DIC) will display READY FOR REMOTE # 2, 3, 4, etc.
4. Wait 10 Minutes: Wait for 10 minutes until the DIC displays PRESS ENGINE START BUTTON TO LEARN, and then press the ENGINE START/STOP button. The DIC display will again show REMOTE LEARN PENDING, PLEASE WAIT.
5. Repeat Waiting Process: Repeat Step 4 two more times. After the third time, all previously known smart keys will no longer work with the vehicle. The remaining smart keys can be re-programmed during the next steps. The DIC display should now show READY FOR REMOTE # 1.
6. Place the New Smart Key: Place the new smart key into the transmitter pocket (inside the center console storage area between the driver and front passenger seats for Cadillac vehicles OR in the front cupholder for Chevrolet and Buick vehicles).
7. Press ENGINE START/STOP: Press the ENGINE START/STOP button. When the smart key is recognized by the vehicle, the DIC display will show that it is ready to program the next smart key.
8. Remove and Test: Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the smart key.
9. Program Additional Smart Keys: To program an additional smart key, repeat Steps 7-9.
10. Exit Programming Mode: When all additional smart keys are programmed, press and hold the ENGINE START/STOP button for approximately 12 seconds to exit the programming mode.

3.3. Using a Diagnostic Tool

If the above methods don’t work, or if you prefer a more professional approach, you can use a diagnostic tool. This method typically involves connecting a specialized device to your vehicle’s OBD-II port (usually located under the dashboard) and following the tool’s on-screen instructions to program the key fob.

1. Purchase a Diagnostic Tool: Acquire a diagnostic tool that supports key fob programming for your 2020 GMC Yukon.
2. Connect the Tool: Plug the diagnostic tool into the OBD-II port.
3. Follow On-Screen Instructions: Follow the tool’s prompts to initiate the key fob programming sequence. This usually involves entering a security code or PIN.

5. Test the Key Fob: After programming, test the key fob to ensure all functions (lock, unlock, remote start, etc.) work correctly.

3.4. Seeking Professional Assistance

If you find the 2020 GMC Yukon key fob programming process too complex or are facing difficulties, consider seeking professional assistance. Automotive locksmiths and dealerships have the expertise and tools to program your key fob quickly and efficiently.

1. Find a Reputable Locksmith or Dealer: Search for local automotive locksmiths or GMC dealerships with good reviews.

3. Provide Vehicle Information: Provide the year, make, and model of your vehicle, as well as any relevant information about your key fob.
4. Have the Key Fob Programmed: The professional will program the key fob for you, ensuring it works seamlessly with your vehicle.

4. Common Issues and Troubleshooting

Even with careful execution, you might encounter issues during the 2020 GMC Yukon key fob programming process. Here are some common problems and how to troubleshoot them:

4.1. Key Fob Not Recognizing

Issue: The vehicle does not recognize the key fob during the programming process.

Troubleshooting Steps:

• Check Battery: Ensure the key fob battery is new and properly installed. A weak battery can prevent the key fob from transmitting signals.
• Verify Compatibility: Double-check that the key fob is compatible with your 2020 GMC Yukon. Refer to your vehicle’s owner manual or consult a professional.
• Reposition the Key Fob: Ensure the key fob is correctly positioned in the transmitter pocket or cupholder, as specified in the programming instructions.
• Check for Interference: Move away from potential sources of interference, such as other electronic devices or metal objects.
• Try Again: Repeat the programming steps carefully, ensuring you follow each instruction precisely.

4.2. Programming Failure

Issue: The programming process fails to complete, and the key fob does not function.

Troubleshooting Steps:

• Ensure Correct Procedure: Verify that you are using the correct programming procedure for your vehicle and key fob.
• Check Security System: Ensure that your vehicle’s security system is not preventing the programming process.
• Wait and Retry: Sometimes, waiting a few minutes and then retrying the programming process can resolve the issue.
• Use a Diagnostic Tool: If possible, use a diagnostic tool to identify any error codes that may be causing the programming failure.
• Seek Professional Help: If the issue persists, consult an automotive locksmith or dealership for assistance.

4.3. Key Fob Works Intermittently

Issue: The key fob functions sporadically, working sometimes but not others.

Troubleshooting Steps:

• Replace Battery: Replace the key fob battery, as a partially depleted battery can cause intermittent issues.
• Clean Contacts: Clean the battery contacts inside the key fob with a cotton swab and a small amount of isopropyl alcohol.
• Check for Damage: Inspect the key fob for any signs of physical damage, such as cracks or broken components.
• Reprogram Key Fob: Try reprogramming the key fob to ensure it is properly synced with the vehicle.
• Check Vehicle’s Receiver: The issue might be with the vehicle’s receiver. Consult a professional to inspect the receiver.

4.4. Remote Start Not Working

Issue: All other functions work except for the remote start feature.

Troubleshooting Steps:

• Check Hood Latch Sensor: Ensure the hood is completely closed, as an open hood can disable the remote start feature.
• Check Error Codes: Use a diagnostic tool to check for any error codes related to the remote start system.
• Verify Remote Start Settings: Ensure that the remote start feature is enabled in your vehicle’s settings.
• Check Vehicle’s Battery: A weak vehicle battery can sometimes prevent the remote start from functioning.
• Consult a Professional: If the issue persists, consult an automotive technician to diagnose and repair the remote start system.

5. The Importance of Regular Maintenance

Maintaining your 2020 GMC Yukon key fob is crucial for its longevity and reliability. Regular maintenance can prevent common issues and ensure your key fob works when you need it most.

5.1. Battery Replacement

The key fob battery is a critical component. Replace it every one to two years, or as soon as you notice the key fob’s range diminishing. Use a high-quality battery that matches the specifications in your owner’s manual.

5.2. Cleaning and Protection

Keep your key fob clean and dry. Avoid exposing it to extreme temperatures, humidity, or direct sunlight. Use a soft cloth to clean the key fob, and consider using a protective case to prevent damage from drops and impacts.

5.3. Regular Testing

Periodically test all the key fob functions, including locking, unlocking, remote start, and the panic button. This helps identify potential issues early, allowing you to address them before they become major problems.

6. Security Tips for Your 2020 GMC Yukon Key Fob

Protecting your key fob is essential to prevent theft and unauthorized access to your vehicle. Here are some security tips to keep in mind:

6.1. Store Key Fob Securely

Always store your key fob in a secure location, away from prying eyes. Avoid leaving it in plain sight in your home or vehicle. Consider using a signal-blocking pouch to prevent thieves from intercepting the key fob’s signal.

6.2. Be Aware of Your Surroundings

Be vigilant in parking lots and public areas. Thieves may use signal-amplifying devices to capture your key fob’s signal when you lock or unlock your vehicle.

6.3. Disable Keyless Entry (If Possible)

If your vehicle allows it, consider disabling the keyless entry feature in high-risk areas. This prevents thieves from unlocking your vehicle without the key fob present.

6.4. Use a Steering Wheel Lock

In addition to securing your key fob, use a physical deterrent such as a steering wheel lock to prevent theft. This adds an extra layer of security and makes your vehicle a less attractive target for thieves.

6.5. Insurance Considerations

Comprehensive insurance coverage is essential for protecting your vehicle against theft. Ensure that your policy includes coverage for key replacement and reprogramming in case your key fob is lost or stolen. According to the Insurance Information Institute, having comprehensive coverage can provide peace of mind and financial protection in the event of a theft.

7. Choosing the Right Key Fob Replacement

If you need to replace your 2020 GMC Yukon key fob, it’s crucial to choose the right one. Here’s what to consider:

7.1. OEM vs. Aftermarket

You have two main options: Original Equipment Manufacturer (OEM) key fobs and aftermarket key fobs. OEM key fobs are made by the vehicle manufacturer and are guaranteed to be compatible with your vehicle. Aftermarket key fobs are typically less expensive but may not offer the same level of quality and reliability.

7.2. Compatibility

Ensure that the replacement key fob is compatible with your 2020 GMC Yukon. Check the part number and consult with a dealer or locksmith to verify compatibility.

7.3. Features

Consider the features you need. Some key fobs offer additional features such as remote start, panic button, and keyless entry. Choose a key fob that meets your needs and preferences.

7.4. Price

Compare prices from different suppliers. OEM key fobs are typically more expensive than aftermarket options, but they offer better quality and reliability.

7.5. Warranty

Check the warranty offered by the supplier. A good warranty provides peace of mind and protects you against defects or malfunctions.
