How to Open Mercedes Trunk Manually Without a Key

Mercedes-Benz is known for its luxurious and innovative vehicles, but like any other car, it can encounter issues with its electronic systems, including the trunk lock. If you find yourself in a situation where you need to access your Mercedes-Benz’s trunk manually without a key or if your key fob battery is dead, don’t worry; there are ways to open it. In this article, we will guide you through the steps to open Mercedes trunk manually without a key.

Safety First

Before attempting to open your Mercedes trunk manually, it’s essential to prioritize safety. Ensure you are in a safe location, away from traffic and any potential hazards. If you are on the side of the road, make sure your hazard lights are on and that you are visible to other drivers. Always exercise caution when working on your vehicle, and if you feel uncomfortable or unsure, consider seeking professional assistance.

Tools You’ll Need

To manually open your Mercedes-Benz trunk, you will need a few tools and items, including:

1. A flathead screwdriver or a sturdy plastic trim removal tool
2. A flashlight or a headlamp (for better visibility if needed)
3. A friend or family member (optional but can be helpful)

Let’s now explore the steps to open your Mercedes trunk manually:

Step 1: Locate the Trunk Release Lever

Most Mercedes-Benz vehicles have a trunk release lever located inside the cabin. It’s typically located on the driver’s side, near the footwell or on the driver’s door panel. Look for a lever or button with a trunk symbol or label.

Step 2: Pull the Trunk Release Lever

Once you’ve located the trunk release lever, pull or press it. This action should activate the trunk latch, causing the trunk lid to pop open slightly. If you hear a click or feel resistance, but the trunk doesn’t open, don’t worry; there’s still a way to access the trunk manually.

Step 3: Access the Trunk Release Cable

In some Mercedes-Benz models, especially older ones, the trunk release lever may not directly connect to the trunk latch. Instead, it activates a cable mechanism that releases the trunk latch. To access this cable, you’ll need to remove the trim panel that covers it.

Use your flathead screwdriver or plastic trim removal tool to carefully pry off the trim panel. Start from the bottom edge, as this is where the clips are usually located. Be gentle to avoid damaging the panel or clips.

Step 4: Locate and Pull the Trunk Release Cable

With the trim panel removed, you should now see the trunk release cable. It will be a thin, flexible cable that connects to the trunk latch mechanism. Gently pull on the cable to release the trunk latch. You may need to use pliers or a similar tool to get a better grip on the cable if it’s difficult to reach.

Step 5: Open the Trunk

Once you’ve successfully pulled the trunk release cable, the trunk should pop open. Lift the trunk lid carefully to access the contents of your trunk.

Alternative Methods

If the above steps don’t work for your Mercedes-Benz model, you may have a more complex trunk release mechanism. In such cases, you can try the following alternative methods:

1. **Emergency Release Handle**: Some Mercedes-Benz vehicles come equipped with an emergency release handle inside the trunk. This handle is typically located near the trunk latch mechanism. Use a flashlight to locate it and pull it to open the trunk.

2. **Accessing the Trunk from the Rear Seat**: In certain Mercedes-Benz models, you can access the trunk from the rear seat by folding it down or removing a panel. Once you have access to the trunk, use the emergency release handle or pull the trunk release cable as described above.


While Mercedes-Benz vehicles are known for their advanced technology and convenience features, it’s important to know how to open the trunk manually in case of emergencies or electronic system malfunctions.
