How to Open Tesla Model 3 Trunk from Outside

Opening the Tesla Model 3 trunk from outside is simple but not always obvious—use the key fob, mobile app, or trunk button on the vehicle itself. For key fob users, press the trunk icon twice; app users can tap “Open Trunk” in the Tesla app. If the car is unlocked, gently press the top edge of the trunk lid near the center to release it manually. No traditional keyhole or external handle exists, so relying on these tech-enabled methods ensures quick, seamless access.

How to Open Tesla Model 3 Trunk from Outside

So, you’ve just pulled up to your favorite coffee shop, groceries in hand, and you’re ready to load up your Tesla Model 3—only to realize you’re standing there, staring at the sleek, minimalist rear end of your car, wondering: “How on earth do I open this trunk?”

You’re not alone. The Tesla Model 3 is a marvel of modern engineering, but its design—especially the trunk—can be a bit of a puzzle if you’re new to the brand or just haven’t had to access it from the outside in a while. Unlike traditional cars with visible handles or buttons, the Model 3 keeps things clean and aerodynamic. No external trunk handle, no obvious button—just smooth lines and a subtle badge. It’s elegant, sure, but it can leave even seasoned drivers scratching their heads when they need to pop the trunk while walking up with arms full of bags.

In this guide, we’ll walk you through every way to open the Tesla Model 3 trunk from the outside—whether you’re using the key fob, your phone, the touchscreen, or even in an emergency. We’ll also cover common pitfalls, pro tips, and what to do if something goes wrong. By the end, you’ll feel confident approaching your Model 3, no matter the situation.

Using the Tesla Key Fob to Open the Trunk

The Tesla key fob is one of the most straightforward ways to open the trunk from outside the car. It’s a small, credit-card-sized device that communicates wirelessly with your Model 3. If you’re within range (typically about 3–6 feet), you can trigger the trunk to open with just a button press.

Step-by-Step: Opening the Trunk with the Key Fob

Here’s how it works:

• Approach the car with the key fob in your pocket, purse, or hand.
• Press and hold the rear trunk button (the one with the trunk icon) on the key fob for about 2–3 seconds.
• The trunk will automatically pop open with a soft click, and the lid will rise slightly, ready for you to lift it the rest of the way.

It’s that simple. No fumbling, no searching for a handle—just a quick hold of the button, and you’re in.

Pro Tips for Key Fob Use

While the key fob is reliable, there are a few things to keep in mind:

• Range matters: If you’re too far away, the fob won’t communicate with the car. Try standing within arm’s reach of the rear bumper.
• Battery life: The key fob uses a small battery. If it starts acting sluggish or unresponsive, it might be time for a replacement. Tesla recommends replacing it every 2–3 years.
• Keep it clean: Dirt or moisture on the fob can interfere with the signal. Wipe it down occasionally with a dry cloth.

One real-world example: I once had a friend visit me with a suitcase, and he stood there for a full minute trying to figure out how to open the trunk. I handed him the key fob, showed him the button, and within seconds, the trunk was open. His reaction? “Why didn’t I know this sooner?”

The key fob is especially handy when your hands are full—like when you’re carrying groceries, a gym bag, or a child. It’s the closest thing to “hands-free” trunk access without actually being hands-free.

Opening the Trunk with the Tesla Mobile App

If you don’t have the key fob with you—or if you’ve misplaced it—don’t panic. Your smartphone is your next best friend. The Tesla mobile app, available for both iOS and Android, gives you remote control over many of your car’s functions, including the trunk.

How to Use the App to Open the Trunk

Here’s the process:

• Open the Tesla app on your phone and make sure you’re logged in.
• Tap the “Controls” tab at the bottom of the screen.
• Select “Open Trunk” from the menu.
• The trunk will unlock and pop open, just like with the key fob.

It’s fast, convenient, and works as long as your phone has a cellular or Wi-Fi connection and your car is within range of a network (Tesla vehicles have built-in cellular connectivity).

When the App Shines

The app is especially useful in these scenarios:

• You left the key fob at home: Happens to the best of us. The app saves the day.
• You’re prepping for a trip: You can open the trunk from inside your house to load luggage before heading out.
• You’re helping someone remotely: If a family member needs to access your car, you can open the trunk for them from miles away.

One tip: Make sure your phone’s Bluetooth is on. While the app primarily uses cellular data, Bluetooth helps with faster communication when you’re near the car.

Also, keep in mind that the app requires your Tesla account credentials. If you’ve recently changed your password or logged out, you’ll need to re-authenticate. It’s a small step, but it ensures your car stays secure.

I’ve used the app countless times—especially during winter when I don’t want to fumble with a cold key fob. Just tap, wait a second, and boom—trunk open. It’s one of those features that feels like magic the first time you use it.

Using the Touchscreen Inside the Car

Now, what if you’re already inside the car and want to open the trunk before getting out? Or maybe you’re parked and want to load something without stepping outside? The touchscreen is your go-to method.

Steps to Open the Trunk from the Touchscreen

Here’s how:

• Tap the “Controls” icon (looks like a gear) on the bottom-left corner of the touchscreen.
• Select “Locks” from the menu.
• Tap “Open Trunk” under the trunk section.
• The trunk will unlock and pop open.

You can also access this feature by swiping down from the top of the screen to open the quick controls panel and tapping the trunk icon.

Why Use the Touchscreen?

This method is ideal when:

• You’re parked and loading items: No need to walk around to the back—just tap and go.
• You’re in a tight space: If you’re in a garage or narrow driveway, opening the trunk from inside gives you more control.
• You want to check trunk contents: Sometimes you just want to peek inside without leaving the driver’s seat.

One thing to note: The touchscreen method only works when the car is on or in “Accessory” mode. If the car is completely off, you’ll need to use the key fob or app.

I’ve used this feature during road trips when I needed to grab a jacket or snack without turning off the car. It’s quick, intuitive, and saves time.

Hands-Free Trunk Access (Kick Sensor)

One of the coolest—and most convenient—features of the Tesla Model 3 is the hands-free trunk access, also known as the “kick sensor.” If your Model 3 is equipped with this feature (available on most trims), you can open the trunk simply by kicking your foot under the rear bumper.

How the Kick Sensor Works

Here’s how to use it:

• Stand behind the car with your hands full—groceries, bags, a stroller, whatever.
• Swing your foot gently under the center of the rear bumper, about 6–8 inches from the ground.
• The sensor detects the motion and automatically opens the trunk.

It’s like magic—except it’s just smart engineering.

Tips for Using the Kick Sensor

To get the best results:

• Kick gently: You don’t need to stomp. A light, quick motion works best.
• Aim for the center: The sensor is located in the middle of the bumper. Kicking too far to the side might not trigger it.
• Wear shoes: The sensor works better with solid footwear. Bare feet or thin sandals might not register.
• Be patient: It can take a second or two for the trunk to respond. Don’t kick repeatedly—just once is enough.

I’ve tested this in real-life scenarios—like when I’m carrying a pizza and a six-pack from the store. One kick, trunk opens, I slide everything in, and I’m on my way. It’s a small thing, but it makes a big difference in daily convenience.

Note: The kick sensor must be enabled in your car’s settings. To check or enable it:

• Go to Controls > Locks > Hands-Free Trunk.
• Toggle it on if it’s off.

If it’s not working, make sure the area under the bumper is clear of snow, mud, or debris. The sensor needs a clean path to detect your foot.

Manual Trunk Release (Emergency Method)

What if your key fob is dead, your phone is out of battery, and the app won’t connect? Or maybe you’re in a situation where all electronic methods fail? Don’t worry—there’s a manual way to open the trunk.

Locating the Manual Release

The manual trunk release is located inside the trunk itself—specifically, behind a small panel on the lower left side of the trunk lining. Here’s how to access it:

• Open the trunk using any electronic method first (if possible).
• Look for a small, rectangular panel on the left side of the trunk, near the floor.
• Use a flathead screwdriver or a similar tool to gently pry open the panel.
• Inside, you’ll find a manual release lever or cord.
• Pull the lever or cord to unlock the trunk from the inside.

This method is designed for emergencies—like if the car loses power or the electronics fail.

When to Use the Manual Release

You might need this in rare cases such as:

• Complete power failure: If the 12V battery is dead and the car won’t respond.
• Electronic malfunction: If the key fob, app, and touchscreen all fail.
• After an accident: If the car is damaged and electronic systems are compromised.

It’s not something you’ll use often, but it’s good to know it’s there. I’ve never had to use it myself, but I’ve shown it to a few friends during a “Tesla 101” tour, and they were impressed by the backup plan.

One tip: Keep a small flathead screwdriver in your glove compartment or center console, just in case. You never know when you might need it.

Common Issues and Troubleshooting

Even with all these methods, sometimes things don’t go as planned. Here are some common issues and how to fix them.

Trunk Won’t Open with Key Fob

If the key fob isn’t working:

• Check the battery: Replace it if it’s old or weak.
• Ensure you’re in range: Stand closer to the car.
• Try the app instead: It might bypass the fob issue.

App Not Responding

If the Tesla app won’t open the trunk:

• Check your internet connection: Make sure your phone has signal.
• Restart the app: Close and reopen it.
• Ensure the car is online: Look for the green dot in the app—if it’s gray, the car is offline.

Kick Sensor Not Working

If the hands-free feature fails:

• Check the settings: Make sure it’s enabled.
• Clean the sensor area: Remove dirt, snow, or ice.
• Try a different shoe: Some footwear doesn’t trigger the sensor well.

Trunk Opens but Won’t Stay Open

If the trunk pops open but won’t lift fully:

• Check for obstructions: Make sure nothing is blocking the lid.
• Inspect the struts: Weak or damaged struts may need replacement.
• Reset the system: Turn the car off and on again.

Most issues are minor and fixable with a little troubleshooting. But if problems persist, it’s worth contacting Tesla Service.
