How to Lock a Tesla Model 3, Y, S, or X

Locking a Tesla Model 3, Model Y, Model S, or Model X is usually automatic when you walk away with your phone key or key fob. You can also lock the car from the touchscreen, the Tesla app, or the key itself. Keep a working key with you and check the lock indicator before leaving valuables or people inside.

What You’ll Need

A working phone key, key card, key fob, or other key supplied for your vehicle.
For app locking: the Tesla app, access to your Tesla account, and a phone with an internet connection. The car also needs connectivity to receive the command.
For touchscreen locking: access to the car’s center touchscreen.

Available keys and exact controls vary by model year, region, and vehicle software. Use the key type supported by your car; not every Model 3, Y, S, or X uses the same key hardware.

Step-by-Step

Get everyone out and close the doors. Make sure all occupants have exited, then close every door and the trunk or liftgate. If a door is not fully shut, the car may not lock as expected. Check that windows are closed if that matters for your situation.
Lock it with the Tesla app. Open the app and select your vehicle. On the vehicle controls screen, tap the lock icon or the control labeled Lock, if shown. Wait for the app to show that the command succeeded or for the lock icon to change. If the app says the car is asleep or offline, give it time to reconnect or use a key or touchscreen instead.
Lock it from the touchscreen. While in the parked car, tap the lock icon on the touchscreen status bar. Depending on software and model, you may also find lock controls under Controls. Confirm the icon indicates locked before you leave. Touchscreen layouts can change, so use the visible lock control rather than assuming a particular menu position.
Use a key card, if your vehicle supports it. For Model 3 and Model Y versions that use a key card, tap the card on the designated reader area, commonly on the driver-side door pillar, to unlock; then use the touchscreen lock control or walk-away locking to secure the car. A key card is not necessarily a direct lock button. Follow the reader markings and your owner’s manual for your model and year.
Use a key fob, if equipped. Press the fob’s lock button, usually identified by a closed-padlock symbol. Some fobs support locking by pressing a button or using a model-specific action. Check the fob instructions for your vehicle instead of relying on a button sequence from another Tesla model.
Enable walk-away door locking for automatic locking. On the touchscreen, open Controls and look for Locks or the walk-away locking setting. Turn on Walk-Away Door Lock or the similarly named option, if available. With a paired phone key or compatible key fob, leave the vehicle and move a short distance away; the car should lock after the key is out of range. Test the setting while nearby and verify the lock status.
Check exceptions and exclusions. If the car does not lock as you walk away, check whether a door or trunk is open, whether the key remains inside or near the vehicle, and whether the relevant walk-away exclusions are enabled. Some vehicles let you exclude a location or a specific door from automatic locking. Set exclusions only if you intend to use them.
Verify the result. Check the app’s lock status, the touchscreen indicator before exiting, or the vehicle’s exterior lock indication where fitted. Do not rely only on folding mirrors or a sound: those cues can depend on settings and may not be enabled. If uncertain, use the app or a key command and wait for confirmation.

Common Mistakes

Assuming walk-away locking is enabled by default. Check the Locks settings; the feature can be turned off or configured differently.
Leaving the phone or key inside. The vehicle may not lock automatically if it detects a recognized key inside or near it. Keep your key with you and confirm the status.
Expecting every key card to have a lock button. A card often serves as a passive key for unlocking and driving, while locking may require the touchscreen, app, or automatic locking.
Closing the doors but forgetting the trunk or another door. An open closure can prevent the expected lock behavior. Look for an open-door warning in the app or on the screen.
Trusting a delayed or stale app display. The app can take time to connect, especially where mobile coverage is weak. Wait for an updated result rather than treating a tap as proof.
Assuming a phone that once worked is still a phone key. Bluetooth, permissions, battery-saving settings, or a changed phone can interrupt detection. Test the key before depending on automatic locking.

Tips

Carry a backup key card or other supported key, especially if you rely on your phone key.
Keep the Tesla app updated and allow the permissions it requests for phone-key operation, including Bluetooth access. Exact permission names depend on your phone.
After changing phones, reinstalling the app, or adjusting phone permissions, confirm the phone key is still paired in the vehicle’s Locks settings.
Learn the manual lock method for your own model and year before relying on walk-away locking. The app is useful for checking status, but a key or touchscreen can be more practical when connectivity is unavailable.
Do not leave a child or pet in a locked vehicle unattended. Locking does not replace checking the cabin, temperature, or occupants.

Troubleshooting

The car will not lock from the app: Confirm you selected the correct vehicle and that the app is signed in. Check your phone’s internet connection, then wait and retry. If the car is offline or the command does not update, use the key fob, touchscreen, or walk-away method if available. Check for an open-door warning.

Walk-away locking does not work: Confirm the setting is enabled under Controls and Locks, and that your phone key or fob is paired and functioning. Move away with the key, not just the phone’s screen locked, and check that the key is not left in the cabin. Review any location or door exclusions. If your phone is the key, check Bluetooth and app permissions, then reopen the app and test again.

The app shows the wrong status: Refresh the vehicle screen or reopen the app after giving it time to connect. If the display remains uncertain, use a physical key or the touchscreen and verify using another available indicator. Avoid repeatedly sending commands while the vehicle is offline.

The key card or fob is not recognized: Make sure you are using a key paired to that vehicle and follow the correct reader location or button instructions for its model. If a key card is damaged or a fob battery is weak, use another paired key and consult the owner’s manual or Tesla support about replacement or pairing.

The vehicle still will not lock: Close all doors and the trunk, move the key away, and try a direct lock command. If there is a persistent alert or a lock appears mechanically stuck, do not force the door; check the vehicle’s displayed message and contact Tesla service if needed.

Frequently Asked Questions

Does a Tesla Model 3 or Model Y lock automatically?
It can, if walk-away door locking is enabled and a compatible phone key or fob is detected leaving the vehicle. Check the setting and verify the lock status each time until you know it works reliably.

How do I lock a Tesla without the app?
Use the touchscreen lock control, a compatible key fob’s lock button, or walk-away locking with a paired key. A key card may unlock the car but may not provide a dedicated lock button.

Can I lock my Tesla with the key card?
It depends on the vehicle’s design and instructions. On many Model 3 and Model Y versions the card is used at the reader to unlock, while you lock with the touchscreen or walk-away feature. Check your owner’s manual.

Why does my Tesla unlock after I walk away?
A recognized phone key or fob may still be close enough to the car, or the vehicle may not have completed locking. Move farther away, check for a spare key nearby, and confirm the walk-away setting and lock status.

Will my Tesla lock if my phone battery dies?
Do not depend on a dead phone as a phone key. Use a paired key card or fob, if available, or another supported method. Carrying a backup key helps avoid being locked out.

Do Model S and Model X lock the same way as Model 3 and Model Y?
The app and touchscreen provide broadly similar lock controls, but keys, readers, and settings differ by model and year. Follow the instructions shown in your vehicle and its owner’s manual.
