How to Fix Tesla Model 3 Not Locking Automatically

So, here are some fixes that will help you resolve the Tesla Model 3 not locking automatically:

Fix 1: Check Your Settings

It is important to check your settings if your Tesla Model 3 is not locking automatically. Even though this might seem like a no-brainer, you should make sure all your settings are correct.

You can check whether “Auto Lock” is enabled on the “Locks” menu of your vehicle’s touchscreen display. In any case, turn it on and lock your vehicle again if it isn’t. Next, if this doesn’t work, try the next step.

Fix 2: Check Your Key Fob

Next, make sure your key fob is in good working order. If your key fob is not functioning correctly, your Tesla Model 3 may not lock automatically if it is part of the security system. Make sure that the battery in your key fob is functioning correctly and that the key fob is not damaged.

The battery should be replaced if it is dead, and your vehicle should be locked once more. Tesla may require you to purchase a new key fob if the one you have is damaged.

Fix 3: Check Your Door Handles

You might also have issues with your door handles if your Tesla Model 3 isn’t locking automatically. You may not be able to lock your vehicle automatically if your door handles are not working properly, and your vehicle’s security system may not recognize that your doors are closed.

If the problem persists, try opening and closing your doors several times. To fix the door handles on your Tesla, you may need to take it to a Tesla service center.

Fix 4: Check Your Software

A Tesla Model 3’s software, including its security system, plays a significant role in how it operates. It is possible for your vehicle to not lock automatically if its software is outdated or has bugs.

If you haven’t checked your vehicle’s software lately, go to the “Software” menu on the touchscreen display and see if there are any updates available. Install an update if it is available, and try locking your vehicle again. You may need to contact Tesla support for further assistance if this doesn’t resolve the issue.

Fix 5: Check Your Sensors

You may also have issues with your sensors if your Tesla Model 3 is not automatically locking. Whenever someone approaches your vehicle, sensors detect it, and if your sensors are not functioning properly, your vehicle may not lock automatically.

It is possible that dirt or debris may be blocking the view of your sensors, so try cleaning them with a soft, dry cloth to fix the problem. It may be necessary to take your vehicle to a Tesla service center if this does not work.

Fix 6: Restart Your Vehicle

You may be able to fix security system issues with your Tesla Model 3 by simply restarting it. Make sure you turn off your vehicle and then turn it back on again, and then lock your vehicle automatically if it does not work.

Fix 7: Reset Your Vehicle’s Computer

Your vehicle’s computer might need to be reset if a restart doesn’t work. Hold down the brake pedal and both steering wheel scroll buttons if the touchscreen display doesn’t turn off after about 10 seconds. Once the display returns, release the buttons. After doing this, your vehicle’s computer should be reset, and you can attempt to lock it again.

Fix 8: Check Your Wi-Fi Connection

In order for your Tesla Model 3’s security system to function correctly, you’ll need a Wi-Fi connection. Your vehicle may not be able to lock automatically if you are not connected to Wi-Fi.

On your vehicle’s touchscreen display, you can check the Wi-Fi connection by selecting the “Wi-Fi” option. Connect your vehicle to a Wi-Fi network if it is not connected to one, and try to lock your vehicle again.

Fix 9: Check Your Mobile App

It is possible to lock and unlock the doors of your Tesla remotely using the Tesla mobile app. Instead of using the mobile app to lock your Tesla Model 3, try the mobile app if your doors aren’t locking automatically. This may resolve the issue, and you will need to take your vehicle to a Tesla service center if it does not.

Fix 10: Check for Physical Obstructions

A physical obstruction could prevent your Tesla Model 3 from automatically locking if your security system isn’t working properly. Make sure your vehicle’s exterior is free of obstructions that may prevent the doors from closing correctly.

Fix 11: Update Your Mobile App

Be sure that the Tesla mobile app is up-to-date if you’re controlling your vehicle remotely. It is possible for your vehicle’s security system to be compromised by an outdated mobile app. If you need to install updates, check your app store.

Fix 12: Check Your Wiring

Last but not least, if none of the above steps have solved your problem, your wiring needs to be checked. Vehicle wiring problems can cause the security system of your vehicle to malfunction, preventing your car from locking automatically. If needed, you can fix this issue by taking your Tesla to a Tesla service center for an inspection and repair.
