Tesla calls it Boombox. Three steps, no app, no subscription. Check your car first, then follow the steps below. Installing from your phone?
Check my car
Will it work on your Tesla? Pick a model and a model year.
Needs the external speaker (Model 3 from Sept 2019, S/X from the 2021 refresh) and software 2023.44+.
Check first: does Toybox → Boombox → Lock Sound exist in your car?
Three steps. No app.
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.
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
Lock the car to hear it.
Walk away or press the key fob. The sound plays through the external speaker.

After an update: Custom lock sound stopped working? See the fix
The car still plays Tesla's default chime
- In Toybox → Boombox → Lock Sound, choose USB again
- Confirm the path is exactly Boombox/LockChime.wav, with the Boombox folder at the top level of the drive
- 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.
- Confirm the filename is exactly LockChime.wav (capital L and C)
- Remove and reinsert the drive, then lock once to retest
USB is greyed out or missing in Boombox
- Update Tesla software to the latest version
- Plug into a USB port that carries data (the glovebox port on newer cars; rear ports only charge)
- Format the drive as FAT32 or exFAT, not NTFS or APFS
- Try a different USB drive; some older drives fail
- Reboot the touchscreen: hold both steering wheel buttons
The sound cuts off, distorts or is quiet
- Keep the clip under 5 seconds
- Download a different sound from the library
- Reformat the drive if you suspect corruption
Go back to the stock chime
- Delete LockChime.wav from the drive (in Boombox/ or at the top level), or switch Lock Sound back to a built-in sound in Toybox → Boombox → Lock Sound

Frequently asked questions
How do I change my Tesla lock sound?
Format a USB drive as FAT32 or exFAT, create a folder named Boombox, and place your WAV file inside named exactly LockChime.wav. Plug the USB into a USB port that carries data (the glovebox port on newer cars) on your Tesla, and open Toybox → Boombox → Lock Sound, then choose USB. Check first: does Toybox → Boombox → Lock Sound exist in your car?
What are the Tesla Model Y 2026 custom lock sounds USB instructions?
For Model Y 2026, place LockChime.wav at Boombox/LockChime.wav on a FAT32 or exFAT drive, insert it into a USB port that carries data (the glovebox port on newer cars; rear ports only charge), and open Toybox → Boombox → Lock Sound, then choose USB. If your drive's plug doesn't fit the port, use a small adapter.
Which Tesla models support custom lock sounds?
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. Legacy years vary by hardware. Use the model/year install-confidence matrix on this page for confirmed, likely, unknown, and unsupported status before you prep your USB drive.
What does 'unknown' mean in the model/year confidence matrix?
Unknown means we could not verify a model/year path with current primary documentation or consistent field reports. It does not mean 'impossible.' Start with the standard Boombox/LockChime.wav checklist, then use the troubleshooting flow if USB does not appear.
What are the Tesla lock sound file format requirements?
Tesla needs a WAV file named exactly LockChime.wav. We recommend 44.1 kHz, 16-bit PCM, inside a Boombox folder on a FAT32 or exFAT USB drive. Keep files 1–5 seconds. All 2,290+ sounds on Tesla Lock Sound are pre-converted to this exact format.
Why is my LockChime.wav not showing up under USB?
In almost every case, one of four things is wrong: the USB format (must be FAT32 or exFAT), the folder path (must be Boombox/LockChime.wav), the filename capitalization (must be exactly LockChime.wav), or the USB port (it has to carry data).
Why does Tesla still play its default sound after I select USB?
Tesla usually falls back to its default sound when one setting or file detail is off. Confirm Lock Sound is set to USB, confirm the path is Boombox/LockChime.wav, confirm the filename is exactly LockChime.wav, then reinsert the USB drive and lock once to retest. If it still plays the default, try the file at the top level of the drive instead; both locations work.
How long can Tesla lock sounds be?
Tesla lock sounds should be 1–5 seconds. Longer sounds may be cut off, so trim them in the converter first.
Can I convert my own audio to a Tesla lock sound?
Yes. Use the free LockChime.wav converter to trim any MP3, M4A, or WAV to 5 seconds and export it in the correct format. Runs in-browser, no upload needed.
Can I use multiple lock sounds on one USB drive?
No. Tesla reads one LockChime.wav at a time. To swap sounds, replace the file on the USB drive.
Are Tesla Lock Sound files safe for my Tesla?
All files use the recommended format (44.1 kHz, 16-bit WAV). As with any vehicle modification, use at your own discretion.
Do custom lock sounds work with Tesla's mobile app?
Yes. Custom lock sounds play when you lock via the app, key fob, or walk-away auto-lock.
