Tesla Lock Sound: Customize & Limitations | Guide

Tesla continues to add personalization touches to its vehicles. Among them, the ability to change the sound emitted when locking your car, once reduced to a simple monotonous beep or, worse, a standard horn. This feature now allows you to give your Tesla a little personality, choosing from predefined sounds or adding your own custom sound.

Here’s everything you need to know to create and install a custom lock sound on your Tesla.

Vehicle Requirements

To use a custom lock sound, your Tesla must be equipped with external pedestrian warning system (PWS)which appeared on vehicles around September 2019. However, exact availability may vary by model and region.

• Some vehicles produced during the transition period may not have the PWS speaker installed, but have the necessary connectivity. In this case, a retrofit via Tesla service is possible.
• An easy way to check: If your Tesla makes a sound at low speed, it has the PWS speaker.

Find Custom Sounds

A page dedicated to custom sounds for Tesla brings together most popular sounds : sound effects from retro video games, extracts from famous cartoons, and other iconic clips. These files are optimized for Tesla vehicles and meet all technical requirements.

Steps:

1. Download the desired file.
2. Rename the file to LockChime.wav.
3. Place the file at the root of a USB key.

There are a few rules to follow so that your sound is recognized by the Tesla:

• The file must be in the format .wav
• It must be less than 1 MB
• The file must have the name LockChime.wav
• It must be in the root directory of USB stickand not in a subfolder

The USB drive used for Dashcam and Sentry Mode videos is usually located in the glove box. To add sound: remove the key, plug it into your computer, add the file and reinsert the key into the car.

Current Limitations

• One personalized sound at a time : Tesla does not allow you to store several sounds and choose them via the touch screen.
• To use multiple sounds, simply rename the file you want to activate to LockChime.wav on the USB stick.
