You're sitting in your Tesla, perhaps enjoying a quiet moment, waiting for someone, or simply taking a break. You want to ensure your vehicle is secure, but you're inside it. How do you lock it without stepping out? It's a common question, and thankfully, Tesla offers several intuitive ways to do just that. Let's dive in!
Step 1: Discovering the Touchscreen Control ️
The most straightforward and primary method for locking your Tesla from the inside is through its large, responsive touchscreen. This is your command center for virtually everything in your vehicle.

Your Digital Locksmith
Locate the Lock Icon: Look at the top of your Tesla's touchscreen. You'll typically find a small lock icon in the status bar. This icon visually represents the current lock status of your doors.
Tap to Secure: A single tap on this lock icon will lock all doors and trunks of your Tesla. The icon will change its appearance (e.g., from an open to a closed padlock, or a change in color) to indicate that the doors are now secured.
Confirm the Lock: You might hear a subtle click or a slight confirmation sound, indicating the successful locking of the doors.
This method is incredibly convenient for a quick lock when you're already settled in the car.
Step 2: Understanding Automatic Locking Features
Tesla vehicles are designed with advanced convenience and safety features, including automatic locking mechanisms. While these primarily function when you exit the vehicle, it's essential to understand how they interact with being inside to avoid unexpected unlocking.
Drive Away Locking ⚡
Your Tesla is smart enough to secure itself when it's in motion.
Speed-Activated Lock: All Tesla models are equipped with "Drive Away Locking." This feature automatically locks all doors (and trunks) once your vehicle's speed exceeds a certain threshold, typically around 5-8 km/h (3-5 mph). So, if you start driving, your car will automatically lock itself.
QuickTip: Slowing down makes content clearer.
Walk-Away Door Lock (and its indoor nuances) ♀️
The "Walk-Away Door Lock" feature is fantastic for locking your Tesla as you leave it. However, when you're inside, it's important to know how it behaves.
Phone Key/Key Fob Detection: If "Walk-Away Door Lock" is enabled and your phone key or key fob is inside the vehicle with you, the car generally will not lock automatically when you move away from the vehicle (even if you were to open a door and close it). This is because the car detects an authenticated key inside, assuming you want to remain unlocked.
Overriding Walk-Away Lock while Inside: If you specifically want to lock the doors from the inside so they cannot be opened from the outside (even if your phone key is detected inside), you must use the lock icon on the touchscreen as described in Step 1. This action temporarily overrides any phone lock settings like "Walk-Away Door Lock."
Important Note: If you open a door from the inside after manually locking it, and your phone key is still detected, the doors may once again become openable from the outside. Always re-check the lock status if you open and close a door while staying in the car.
Step 3: Child Protection Locks for Rear Doors
If you have children in the back seats, Tesla's child protection locks are a crucial safety feature to engage. These prevent the rear doors from being opened from the inside.
Activating Child Locks ️
Access Controls: On your Tesla's touchscreen, tap on "Controls."
Navigate to Locks: Then, select "Locks" from the menu options.
Find Child Lock: You'll see an option for "Child Lock."
Select Doors: You can choose to engage the child lock on "Both" rear doors, or select "Left" or "Right" to apply it to a specific door.
Recommendation: It's highly recommended to turn on child locks whenever children are seated in the rear seats for their safety.
Remember, child locks only prevent opening from the inside; they don't affect the ability to open the doors from the outside.
Step 4: The Mobile App and Its Limitations (When Inside)
While the Tesla mobile app is incredibly powerful for remote control of your vehicle, including locking and unlocking, it has important nuances when you are inside the car.
When the App Isn't the Best Option for Internal Locking
QuickTip: Return to sections that felt unclear.
Phone Key as "Primary": If you're using your phone as a key (which is the default for many Tesla owners), your vehicle uses Bluetooth to detect your phone's proximity. Crucially, the vehicle often cannot tell whether your phone is physically inside or outside the car.
Security Implications: If you leave your paired phone inside the vehicle with Bluetooth enabled, it's essentially the same as leaving your physical keys in the car with the doors unlocked. If you then try to lock the car using the mobile app from inside the car, the car may still unlock if an exterior door handle is pulled because it detects the phone key inside.
Best Practice: For locking the doors while you are inside, the touchscreen icon (Step 1) is the most reliable and secure method. The mobile app is best suited for locking/unlocking when you are away from the vehicle.

Step 5: Troubleshooting and Important Considerations
Sometimes, things don't go as planned. Here are a few tips and considerations regarding locking your Tesla while in it.
What to Check If It Won't Lock troubleshoot
Doors/Trunks Fully Closed? A common reason for not being able to lock is an open door or trunk. Ensure all doors, the front trunk (frunk), and the rear trunk are completely closed. Your Tesla will typically flash its hazard lights three times if a door or trunk is open and it can't lock.
Phone Key/Key Fob Interference: If you have multiple keys (phone key, key card, key fob) in the vehicle, or if a paired phone's Bluetooth is on, it might interfere with certain automatic locking functions. Always use the touchscreen for definitive interior locking.
Software Glitch: In rare instances, a software glitch might affect the touchscreen's responsiveness. If the lock icon isn't responding, try a soft reset of your touchscreen (refer to your owner's manual for specific instructions for your model, but generally involves holding down both scroll wheels on the steering wheel until the screen goes black).
"Unlock on Park" Setting: Your Tesla has a setting called "Unlock on Park." If enabled, this feature will automatically unlock all doors when you shift into Park. If you want to remain locked when in Park, ensure this setting is disabled or manually re-lock using the touchscreen after parking. You can find this under Controls > Locks > Unlock on Park.
