One file. The right place.

A visual guide to the USB root folder, duplicate filenames, and keeping your existing Dashcam files safe.

The root is simply the first level you see when opening your USB drive. It is not a special folder you need to create.

Your USB drive
LockChime.wav ← right here
TeslaCam · keep existing files

Put the file beside folders, not inside them.

Copy LockChime.wav directly onto the intended USB volume. Keep your existing TeslaCam folder in place. Other Boombox instructions may describe a Boombox folder for other features; do not assume that those instructions describe custom lock sound installation.

One exact name for one chosen sound.

Web browsers often save repeated downloads as LockChime (1).wav or add a similar number. Choose the file you want and rename it back to LockChime.wav before copying. If a file with that name already exists on the USB, keep a backup on your computer before replacing it.

Make extensions visible.

Some file managers hide extensions such as .wav. Check your file manager’s display options so that you can confirm the whole name. Avoid a double extension such as LockChime.wav.wav, and do not rename compressed audio to pretend it is WAV.

Phones can add an extra step.

A mobile browser may save the audio in Downloads or open a file preview. Use your device’s file manager to locate the download, then copy it with a compatible USB adapter or transfer it to a computer first. We cannot tell from a web page whether a file was successfully copied onto a drive.

Keep the drive’s existing job intact.

Back up important recordings before changing storage. Do not format a drive that is already working just to add the sound. If your USB connection or filesystem needs attention, follow the instructions for your model and year in Tesla’s manual.

Once the file is in place, follow the installation guide to choose USB in Lock Sound and test while parked.
