Most-downloaded LockChime files
Each file downloads as LockChime.wav, a 44.1 kHz, 16-bit WAV, so it goes straight on the drive without converting or renaming.
What is a LockChime?
Tesla's Boombox feature lets you replace the factory lock chime with any WAV file. The Tesla LockChime file (sometimes searched as "tesla lockchime" or "lockchime tesla") works the same way on every supported model: the car reads from a specific path on your USB drive: Boombox/LockChime.wav. It plays that file through the external pedestrian-warning speaker every time you lock. The filename must be exact. The folder must be exact. Get either wrong and you get the stock sound.
Every sound in this library downloads with the correct name and format already set, so there's nothing to convert or rename. The feature has been available since Tesla's 2023 Holiday Update (software 2023.44) and works on all current models with an external speaker.
File spec and USB path
USB_DRIVE/
└── Boombox/
└── LockChime.wavIf the car does not pick the file up from Boombox/, try putting LockChime.wav at the top level of the drive instead. Both locations work.
Tesla's only hard requirement is a WAV file named exactly LockChime.wav. These values are recommended for clean playback, and every download here already matches them:
| Spec | Value |
|---|---|
| File format | WAV (required) |
| Sample rate | 44.1 kHz |
| Bit depth | 16-bit |
| Duration | 1–5 seconds |
| File size | under 1 MB |
| USB format | FAT32 or exFAT |
The car plays the stock chime?
- Filename.
lockchime.wavandLockChime.WAVboth fail. - Container. A renamed MP3 or M4A still has the wrong data inside. Export a real WAV, or use the converter.
- Path. Use
Boombox/LockChime.wav. There is noLocked/subfolder.
Custom lock sounds need the car’s external pedestrian-warning speaker (Model 3 built September 2019 or later, Model S and Model X from the 2021 refresh, every Model Y and Cybertruck) and software 2023.44 or later. Check your car in the install guide.
Common questions
What is a LockChime file?
LockChime.wav is the exact filename Tesla looks for on a USB drive to play a custom lock sound. When you lock the car, Tesla checks the connected USB for Boombox/LockChime.wav and plays it instead of the factory chime.
Where does the file go on the USB drive?
Create a folder named Boombox at the root of your USB drive, then place LockChime.wav inside it. The full path is Boombox/LockChime.wav (no Locked/ subfolder, nothing in between). If the car does not pick the file up from Boombox/, try putting LockChime.wav at the top level of the drive instead. Both locations work.
What happens if LockChime.wav is misnamed or the wrong format?
The car plays the stock chime and shows no error. The usual causes are a filename that is not exactly LockChime.wav (the check is case-sensitive), an MP3 or M4A renamed to .wav instead of a real WAV file, and a file buried in extra subfolders.
Do the downloads need any conversion?
No. Every file in this library downloads already named LockChime.wav and formatted to 44.1 kHz / 16-bit WAV. Drop it into the Boombox folder and it plays immediately.
Which Teslas support a custom LockChime?
Model Y (all years), Model 3 (built September 2019 or later), Model S and X (2021 refresh or later), and all Cybertrucks. The feature requires an external pedestrian-warning speaker and software 2023.44 or newer.
What audio format does LockChime.wav need to be?
The only hard requirement is a WAV file named exactly LockChime.wav; Tesla doesn't publish a stricter spec. For clean, consistent playback, this library formats every download to the widely-used best practice: 44.1 kHz sample rate, 16-bit, 1–5 seconds long, and under 1 MB.
