Overview
Tesla Boombox Studio is a small web sound library for Tesla owners who want to change the lock sound or add sounds to Boombox. Its main job is to take the fiddly part out of the process: it lets you preview a sound in the browser and download it already named LockChime.wav and converted to WAV, which is what the car looks for on the USB drive.
Part of the library is generated in the browser. A set of short synthesised chimes, such as a classic chirp, a sci-fi sweep and a playful duck-like squeak, are built from simple waveforms with the Web Audio API and rendered to a WAV file when you download them. The rest of the library consists of short clips that appear in a separate curated section of the site.
The site also includes a three-step setup guide and an FAQ covering the questions people ask most: where to put the file, how to select it in the car, which vehicles support it and what to do when the sound does not change. The interface is currently in Chinese.
An honest note: Tesla changes Toybox features through software updates, and support depends on your vehicle having the external pedestrian warning speaker. Treat the site as a convenient helper and check your car's owner's manual for the current official requirements.
Key features
One-click LockChime.wav download
Choose a sound and pick the lock-sound download option. The file is converted to WAV and named LockChime.wav, so you can copy it straight to the root of your USB drive without renaming or converting it yourself.
In-browser preview
Every sound can be played in the browser before downloading, so you can judge length and loudness. A lock sound plays every time you lock the car, so short and pleasant usually beats loud and long.
Synthesised chimes
The core set of sounds is generated from oscillator settings (waveform, start and end frequency, duration) and rendered to WAV on your device. These are original, simple tones rather than recordings.
Setup guide and troubleshooting FAQ
A short guide covers the three steps: download the file, copy it to the USB root, then in the car open Toybox, then Boombox, enable the lock sound and choose USB. The FAQ explains the usual fixes when the sound does not apply.
USB safety reminder
The site reminds you to turn off Dashcam before removing or editing the USB drive and to turn it back on afterwards, which helps avoid corrupting the drive.
How to use Tesla Boombox Studio
- Open Tesla Boombox Studio and browse the sound library. Tap a card to preview the sound.
- When you find one you like, choose the lock-sound download. The file is saved as LockChime.wav.
- In the car, turn off Dashcam, then remove the USB drive from the glove box (or the port your car uses for Dashcam).
- On a computer, copy LockChime.wav to the root of the drive, not inside the TeslaCam folder or any other folder. Keep the file under 1 MB.
- Put the drive back, turn Dashcam on again, then open Toybox, then Boombox, enable the lock sound and select USB.
- Lock the car to test it. If the old sound still plays, switch to a built-in sound and then back to USB, and check the file name, location and size.
Who it’s for
- Tesla Model 3, Model Y, Model S and Model X owners whose car has the external pedestrian warning speaker.
- Owners who want a custom lock sound but do not want to edit, convert or rename audio files themselves.
- People who prefer short, simple chimes that will not annoy neighbours in a car park.
- Anyone setting up a USB drive for the first time who wants a plain step-by-step checklist.
FAQ
- Which cars support a custom lock sound?
- The site states that Model 3, Model Y, Model S and Model X built from around September 2019 onward with the pedestrian warning speaker are supported, on software version 2023.44.30 or later. Tesla may change this, so confirm in your car's owner's manual.
- What are the file requirements?
- The file must be a WAV named LockChime.wav, smaller than 1 MB, placed in the root directory of the USB drive.
- I copied the file but the car still plays the old sound. What now?
- Switch the lock sound to a built-in option and then back to USB. If it still fails, check the exact file name (including the .wav extension, which some computers hide), that it is in the root folder and that it is under 1 MB.
- Can I use any sound I find online?
- Only use sounds you have the right to use: ones you made yourself, ones released under a licence that permits this, or ones you have permission for. A lock sound is played in public, so it is worth choosing something original.
- Is the site affiliated with Tesla?
- No. Tesla Boombox Studio is an independent tool made by POMODIARY and is not affiliated with or endorsed by Tesla.
