Steps

  1. Copy to USB

    Download your sound. Every file arrives named LockChime.wav in 44.1 kHz, 16-bit WAV, the recommended spec for clean playback. On a FAT32 or exFAT USB drive, create a folder named Boombox and place LockChime.wav inside it. Full path: Boombox/LockChime.wav. The only hard Tesla requirement is a WAV file named LockChime.wav.

    Library downloads and voice generator clips both arrive already named, so there is nothing to rename.

    To format: on macOS, Disk Utility → Erase → MS-DOS (FAT); on Windows, right-click the drive → Format → FAT32. Any size works, even 64 MB.

    Boombox takes a capital B. No subfolders: place LockChime.wav directly inside Boombox/, one file at a time.

    Folder tree: the USB root holds one Boombox folder, and LockChime.wav sits inside it.Folder tree: the USB root holds one Boombox folder, and LockChime.wav sits inside it.

  2. Plug into your Tesla

    Insert the drive into a USB port that carries data (the glovebox port on newer cars; rear ports only charge). Give the car a few seconds to index the drive. Open Toybox → Boombox → Lock Sound, then choose USB.

    If the first port does not show USB in the menu, try another data port.

    Lock the car to hear it.

    Walk away or press the key fob. The sound plays through the external speaker.

Most common Model Y failure: rear-port plug

If Boombox shows USB as greyed out, move the stick to a USB port that carries data (the glovebox port on newer cars; rear ports only charge) and retry.

FAQ

Does Model Y Juniper (2025+) support custom lock sounds?

Yes. Juniper supports the same Boombox/LockChime.wav workflow as earlier Model Y. If your drive's plug doesn't fit the port, use a small adapter.

Where is the data USB port on Model Y?

A USB port that carries data, not a rear one. Step 2 has the details.

What's the most common Model Y install failure?

Plugging into a rear USB port out of habit. Those only charge, and the Boombox menu shows USB as unavailable until you move the stick to a data port.
