2 min read 04-02-2025

The 2024 GMC Sierra boasts a range of impressive features, but knowing how to properly secure your tailgate is crucial for both security and convenience. This guide will walk you through the various methods of locking your tailgate, ensuring your cargo remains safe and sound.

Understanding Your Sierra's Tailgate Locking System

The 2024 GMC Sierra's tailgate locking mechanism is designed for ease of use and robust security. Unlike some older models, the locking mechanism is integrated directly into the tailgate latch. This means there are no separate locks or keys involved. The system is primarily controlled through your vehicle's central locking system.

Method 1: Using the Key Fob

This is the most convenient method for locking your tailgate.

Step 1: Ensure your key fob has a working battery. A weak battery can interrupt the signal.
Step 2: Locate the lock/unlock buttons on your key fob. Most GMC key fobs have distinct buttons for locking and unlocking.
Step 3: Press the lock button. This will lock all doors, including the tailgate.

Important Note: The tailgate will only lock if the vehicle's doors are locked. If the doors are unlocked, pressing the lock button on your key fob will only lock the doors, leaving the tailgate unsecured.

Method 2: Using the Interior Door Lock Controls

The inside of your Sierra offers another simple way to secure the tailgate.

Step 1: Make sure you're inside your vehicle.
Step 2: Locate the central locking mechanism, usually a button or switch on your driver's side door panel.
Step 3: Press the lock button. This will lock all doors and the tailgate simultaneously.

Method 3: Manually Locking the Tailgate (If Applicable)

While the 2024 GMC Sierra primarily relies on the central locking system, some higher trims or optional packages might include a manual lock on the tailgate itself. If your Sierra has this feature:

Locate the manual lock: Check the inside of the tailgate for a small, usually lever-style, lock.
Engage the lock: Push or turn the lever to lock the tailgate.

Troubleshooting Tailgate Locking Issues

If you are experiencing problems with your tailgate locking mechanism:

Check your key fob battery: A weak battery can disrupt the signal to the vehicle.
Inspect the tailgate latch: Make sure there's no debris or obstruction preventing the latch from engaging properly.
Verify the vehicle's battery: A low vehicle battery can also interfere with the central locking system.
Consult your owner's manual: Your manual provides detailed information on your Sierra's specific features and troubleshooting steps.
Visit a GMC dealership: If the problem persists, consult a qualified GMC technician for professional assistance. They can diagnose and repair any underlying issues.

Keeping Your Cargo Secure: Additional Tips

While locking your tailgate is essential, consider these extra steps for enhanced security:

Use a tailgate lock: Aftermarket tailgate locks provide additional security. These are especially beneficial if you frequently haul valuable items.
Utilize a cargo cover: A tonneau cover will conceal your cargo from view, deterring theft.
Park in well-lit areas: Visibility discourages potential thieves.

By following these methods and tips, you can ensure your 2024 GMC Sierra's tailgate remains securely locked, protecting your valuable cargo and providing peace of mind. Remember to always consult your owner's manual for specific instructions and troubleshooting advice related to your vehicle.
