Tesla Custom Lock Sound: LockChime.wav and Boombox Setup Step by Step

You can swap the short chime your Tesla plays when it locks for a sound of your choice. All you need is a USB drive, a correctly named audio file and a few taps. Here are the steps and the most common mistakes.

What you need

• External speaker (PWS): If the car makes a sound outside at low speed, it has one. Some older cars do not support the feature.
• Software: Sources point to software 2023.44.30 or later. On older versions the menu may not appear.
• Audio file: .wav format, smaller than 1 MB, named LockChime. A short sound of a few seconds works best.
• USB drive: A FAT32 or exFAT drive generally works.

Step by step

1. Copy the file as LockChime.wav to the root of the USB drive. If it sits inside a folder, the car may not find it.
2. Plug the drive into the glovebox USB port. On many newer models the ports in the center console are charge-only.
3. Open Toybox from the apps at the bottom of the screen.
4. In Boombox, find Lock Sound and choose USB.
5. Lock the car and listen.

If it doesn’t work

• Check the name and extension; a double extension like LockChime.wav.wav is common.
• The file must be at the top level of the drive, not in a folder.
• If you remove the drive, the car falls back to the default sound; leave it plugged in.
• Some owners report that temporarily turning off Sentry Mode helps.
• If the lock sound is switched off in Boombox, neither the custom nor the default sound plays.

Choosing a sound

It plays outside, so keep it short, polite and neighbor-friendly. Avoid copyrighted music or movie clips; use your own recording or a freely licensed sound, and respect local noise rules.

Want sound inside the cabin too?

The lock sound plays outside. For an engine sound inside the car while driving, see how to change Tesla sounds and the free Wind Asist Drive web app.
