Why This Tool
Not another sound library
Every other lock chime site hands you someone else's clip. This one lets you build from scratch.
Multi-instrument layering
Stack bells over bass over pads. Each layer is fully independent — mute, tweak, or remove without affecting others.
Real synthesis engine
Harmonics, pitch bend, chorus detuning, reverb convolution — a full synthesizer running entirely in the browser.
Visual timing timeline
See exactly when each instrument plays across the timeline — no guessing which note fires when.
Correct format, every time
44.1kHz · 16-bit PCM · Mono · Named LockChime.wav. Already compatible. No converter needed.
Installation Guide
Get it on your Tesla
Community-documented workflow for compatible Tesla vehicles. Takes about two minutes.
1
Design and export your chime
Use the studio below. When satisfied, click Export LockChime.wav. On desktop it downloads directly. On iPhone, tap Save to Files in the share sheet that appears — the file will be in your Files app ready to copy to USB.
2
Remove the USB from your glovebox
Open your Tesla's glovebox. There's a USB drive inside used for Sentry Mode and Dashcam. Remove it and plug it into your computer.
3
Copy the file to the root of the drive
Drag LockChime.wav directly onto the USB drive — not inside any folder. It should sit at the top level, next to the TeslaCam folder. The filename must be exactly LockChime.wav — capital L and capital C, with no spaces.
4
Return USB and activate in Boombox
Plug the USB back into the glovebox. On the touchscreen go to Toybox → Boombox → Lock Sound, then select USB from the dropdown.
5
Lock the car to test
Lock via the app, key card, or door button. You should hear your chime. Some owners report the sound is saved internally after first activation — check your Boombox settings to confirm it persists without the USB.
Compatibility: This workflow has been reported to work on Model 3, Model Y, Model S, Model X, and Cybertruck running software 2023.44.25+ (2023 Holiday Update). Feature availability may vary by vehicle configuration, region, and software version.
