Boombox
Make a custom Tesla lock chime
Your car, your goodbye noise
Tesla's Boombox plays sounds from a USB drive, and the lock chime is the one everybody hears. Getting a sound onto the car normally means an audio editor, a format conversion, and a filename rule that fails silently if you get it wrong.
- Record or import, then trim on a waveform with the car's own duration rules shown as you drag.
- Exported in the format the car reads — correct sample rate, channel count, and bit depth, written to the
Boomboxfolder. - The LockChime rule handled for you: the car looks for exactly one LockChime.wav, so promoting a new one demotes whatever held the slot before.
- Filename rules enforced — the character set and length the car actually accepts, measured on a real vehicle rather than guessed.
Why sounds fail on the car
The most common reason a Boombox sound doesn't appear is a filename or format the car rejects without saying so. Custom Shop's drive diagnostic reads a drive and tells you exactly which file broke which rule — where Tesla's own screen says only that something is invalid.
The duration rule matters too: the car enforces a length window on the lock chime specifically, not on ordinary Boombox sounds, and the app applies it exactly where it belongs.
Questions owners ask
How do I add a custom lock chime to my Tesla?
Put a file named LockChime.wav in a folder called Boombox at the root of a USB drive formatted as exFAT or FAT32, plug it into the car, and enable Boombox. Custom Shop records, trims, and exports in the exact format and filename the car expects.
What format does a Tesla Boombox sound need to be?
A WAV file in the Boombox folder of a USB drive. Custom Shop writes the correct sample rate, channel count, and bit depth automatically, and enforces the filename character set and length the car accepts.
Why isn't my Boombox sound showing up in the car?
Usually a filename or format the car rejects silently, or a drive whose folder layout confuses it. Custom Shop includes a drive diagnostic that names the specific file and the specific rule it broke.
