How to Fix a Model 3 That Won't Lock

  • Close all the windows and doors.
  • Don't freak out if your Model 3 doesn't lock when you walk away. Check that all windows and doors are closed correctly in their place. What you should do is:
  • Open and then close each door on your Tesla.
  • To raise the windows, use the window adjustment buttons.

Examine Your Seatbelt Sensor to See If It Is Faulty

If you discover that every window and door is properly closed, you might have a broken seatbelt sensor. If the car detects that there is a person inside the car, the Model 3's walk-away Tesla door lock feature won't activate.

Your automobile might believe someone is driving at speed while still seated in the front seat if the sensor is malfunctioning.

You'll need to take your car in for maintenance to have the seatbelt sensor inspected and changed in order to resolve the software issue with this.

Verify Your Driver Profile Preferences

Check your driver profile settings if your Model 3 still won't lock. If you unintentionally turned off the walk-away locking take-away door lock option in the settings, your doors won't lock.

Follow these procedures to see if you disabled the lock option in your driver profile:

  • On the touchscreen, tap "Controls".
  • Choose "Locks."
  • Select "Walk Away Door Lock."
  • Slide the toggle to the right to turn on the function.

Stop Your App's Battery Optimization

Battery optimization may be the cause of your Model 3 not locking if you're using the Tesla mobile app. Due to the fact that it disables connection between your phone and the vehicle, this feature can stop your car from locking when you walk away.

The techniques below can be used to turn off battery optimization in your Tesla app.

  • Open the Settings app on your smartphone.
  • Click "Battery."
  • Then select "Battery Optimization."
  • Look for the Tesla app and select it.
  • Simply choose "Don't Optimize."

Tesla Customer Support

It is best to get in touch with Tesla customer service if none of the aforementioned fixes succeed. They might be able to assist you in identifying the issue and finding a fix.

Additionally, if your car's walk-away door lock button doesn't operate properly, you might be dealing with a bigger problem. So it's wise to call customer service and err on the side of caution.

Go to a Tesla service facility

The next best course of action if your Model 3 still won't lock is to go to a Tesla service facility. They might be able to identify the issue and resolve it for you.

Knowing If Your Model 3 Is Locked

You might be asking how to verify that the auto-locking feature functions now that you understand how to resolve the problem. For example, you wouldn't want to assume that your car is locked next drive, just to return and discover that it isn't.

The Side Mirrors Retract

You can check the side mirrors to see if the key inside your Model 3 is locked. The side mirrors will automatically fold inside when you lock the vehicle.
