2019 GMC Yukon Key Fob Programming Guide

Quick Reference

Step-by-step On-Board Programming

Good news! Your 2019 GMC Yukon supports on-board programming, meaning you can program new key fobs yourself without a trip to the dealership or a locksmith. You will need all existing fobs as well as any new fobs you wish to program. This process will erase all previously programmed fobs, so ensure you have everything ready before you begin.

1. Get Inside: Enter the vehicle and close all doors.
2. Insert Key: Insert your working key (or the new key you wish to program if it has an integrated key blade) into the ignition.
3. Turn to ON: Turn the ignition to the "ON" position (do not start the engine). You will see the "PRESS ENGINE START BUTTON FOR REMOTE LEARN" message display on the Driver Information Center (DIC).
4. Press Start Button: Press and hold the "Engine Start/Stop" button until the DIC message disappears. This may take a few seconds.
5. Remove Key: Remove the key from the ignition.
6. Press Lock & Unlock: On the first new remote you wish to program, simultaneously press and hold the "Lock" and "Unlock" buttons for approximately 15 seconds. The DIC will display "REMOTE LEARN ACTIVE" and then, upon successful programming, "REMOTE LEARN SUCCESSFUL."
7. Repeat for Additional Fobs: For any additional fobs, repeat step 6. Always ensure you program all fobs, including existing ones, during the same session, as the process erases previously learned fobs.
8. Exit Programming Mode: Once all fobs are programmed, turn the ignition to the "OFF" position or open the driver's door to exit programming mode. Test all key fobs to ensure they are working correctly.

Battery Replacement

Your 2019 GMC Yukon key fob uses a CR2032 coin cell battery. Here's how to replace it:

1. Locate the Release Button: On the side of the key fob, you'll find a small release button. Press it to release the emergency key blade.
2. Remove Key Blade: Pull out the emergency key blade.
3. Pry Open the Fob: With the key blade removed, you'll see a small slot. Use a small flat-head screwdriver or a coin to gently pry open the two halves of the key fob.
4. Remove Old Battery: Carefully remove the old CR2032 battery.
5. Insert New Battery: Insert the new CR2032 battery, ensuring the positive (+) side is facing up.
6. Snap Fob Together: Carefully align the two halves of the key fob and snap them back together until you hear a click.
7. Reinsert Key Blade: Reinsert the emergency key blade.

Where to Buy a Replacement Fob

When it comes to replacing your 2019 GMC Yukon key fob, you have a few options, each with its own pros and cons:

• Dealership: While often the most expensive option (expect to pay $200 - $400 for the fob and programming), you're guaranteed to get an OEM product and professional programming. This is a good option if you want peace of mind and don't mind the cost.
• Automotive Locksmith: A local automotive locksmith can often provide and program a new key fob for significantly less than a dealership (typically $150 - $300). They often have access to both OEM and high-quality aftermarket fobs and their services are generally quicker. This is a great balance of cost and convenience.
• Online Retailers (Amazon, eBay, etc.): You can find new and used key fobs online for a much lower price (often $30 - $80 for the fob itself). However, be cautious when purchasing from third-party sellers to avoid counterfeit or incompatible fobs. While you can program the fob yourself (as outlined above), you'll still need to get the integrated key blade cut if your fob has one. This will require a locksmith or a dealership, adding to the total cost. This is the most DIY-friendly option if you're comfortable with the risks and want to save money.

Important Note on Key Blades: If your replacement fob has an integrated key blade, it must be cut by a locksmith or dealership to match your vehicle's ignition and door locks. This is a separate service from programming the remote functions.
