/ steps

Six steps. No app.

Download a sound

Pick from the library, or generate one with AI voice. Save the .wav locally.

File must end in .wav. We tag the filename you need automatically.

Format your USB

FAT32 or exFAT. Any size — even 64 MB works. Empty stick recommended.

macOS: Disk Utility → Erase → MS-DOS (FAT). Windows: right-click → Format → FAT32.

Make /Boombox/Locked/

Create the folder hierarchy on the stick — case sensitive on some firmware.

Boombox/ at the root. Inside, a Locked/ folder for lock chimes. Other folders for park, music, etc.

Drop the WAV in /Locked/

Rename it LockChime.wav (or anything; the car uses the first .wav alphabetically).

Multiple .wav files? The car cycles through them in alphabetical order on each lock.

Plug into front USB-C

On Model 3/Y the right-side front USB-C. On S/X the center console. CT: rear console.

USB-A works with an adapter. The rear ports do not work for Boombox.

Lock the car

Walk away or hit the key fob. You'll hear your sound through the external speaker.

No sound? Settings → Toybox → Boombox → Lock Sound → enable + select file.

Driveway-Grade Pre-Flight Checklist

Do this 60-second check before you walk to the car. It prevents almost every "USB not showing" failure.

  • USB is formatted as FAT32 or exFAT (not NTFS/APFS).
  • File is named LockChime.wav exactly (including capitalization).
  • Path is Boombox/LockChime.wav at USB root.
  • USB is in a Tesla data port (rear ports are power-only).
  • Sound length is under 5 seconds.

Need exact specs? Use the LockChime.wav installer and Tesla USB format guide. For the exact 1-5 second recommendation, see the Tesla lock sound duration guide.

Detailed Instructions

Step 2: Copy to USB Drive

Create a folder named Boombox on your USB drive (FAT32 or exFAT), then copy LockChime.wav inside it.

Correct path: USB Drive/Boombox/LockChime.wav

Formatting from Mac or Windows? Follow our FAT32 vs exFAT USB walkthrough.

Common mistake: wrong folder

LockChime.wav must go inside the Boombox folder, not the USB root directory. The correct path is always Boombox/LockChime.wav.

Confidence check before you leave your computer

Open the USB and visually confirm you see one file at Boombox/LockChime.wav. This one check catches almost every install issue.

Step 3: Connect to Tesla

Insert the USB drive into your Tesla's front USB port (located in the center console or glovebox area).

  • Model S/X: Center console compartment
  • Model 3/Y: Center console or glovebox
  • Cybertruck: Center console USB-A port

Model/year uncertainty to account for

USB data-port layout can vary by model year, trim, and market. If your first port doesn't show the USB option in Boombox, test the other front port or glovebox data port before changing files.

Step 4: Activate in Tesla Settings

Navigate through your Tesla's touchscreen menu:

  1. Tap Toybox on the main screen
  2. Select Boombox
  3. Choose Lock Sound
  4. Change from "Default" to "USB"
  5. Test by locking your vehicle!

30-second first-lock confidence test

  1. Step out, close all doors, and lock once with the app or key card.
  2. If you hear your custom clip, setup is done.
  3. If Tesla still plays Light Cycle, re-check file path and filename, then open our 7-fix troubleshooting guide.

Frequently Asked Questions

What are the Tesla Model Y 2026 custom lock sounds USB instructions?

For Model Y 2026, use a USB-C drive or USB-A-to-C adapter, place LockChime.wav at Boombox/LockChime.wav on a FAT32 or exFAT drive, insert it into a front data USB port such as the glovebox port, then go to Toybox → Boombox → Lock Sound → USB.

Which Tesla models support custom lock sounds?

Model Y, Model 3, Model S, Model X, and Cybertruck are the primary supported lineup. Legacy years vary by hardware and firmware. 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 lock sounds must be in WAV format (44.1kHz, 16-bit PCM), named exactly LockChime.wav, and placed inside a Boombox folder on a FAT32 or exFAT USB drive. The file should be 1-5 seconds long. All 1,862+ sounds on TeslaLockSound are pre-converted to this exact format.

What audio format should Tesla lock sounds be?

Tesla lock sounds must be in WAV format and named exactly 'LockChime.wav', placed inside a 'Boombox' folder on your USB drive (path: Boombox/LockChime.wav). All our sounds are professionally converted to Tesla-compatible WAV format (44.1kHz, 16-bit PCM) for Boombox-compatible Tesla installs.

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 (must be a data port, not power-only).

Why does Tesla still play Light Cycle after I select USB?

Tesla usually falls back to Light Cycle when one setting or file detail is off. Confirm Boombox is set to USB, confirm the exact path is Boombox/LockChime.wav, confirm the filename is exactly LockChime.wav, then reinsert the USB drive and lock once to retest. For the Tron/Light Cycle fallback explainer, see /blog/tesla-tron-mode-sounds-lock-turn-signal.

How long can Tesla lock sounds be?

Tesla lock sounds should be between 1-5 seconds long. Longer sounds may be cut off by the system. All sounds in our library are within the ideal duration range.

Can I convert my own audio to a Tesla lock sound?

Yes. If you have an MP3, M4A, WAV, or other audio file, you can convert and trim it to the exact Tesla format using our free LockChime.wav converter. It trims to 5 seconds and exports LockChime.wav directly in your browser — no upload needed.

Can I use multiple lock sounds on one USB drive?

No, Tesla only recognizes one 'LockChime.wav' file at a time. To change sounds, you need to replace the file on your USB drive with a different one.

Are TeslaLockSound files safe for my Tesla?

Our audio files follow Tesla's recommended specifications (44.1kHz, 16-bit WAV format). However, as with any vehicle modification, you use these sounds at your own discretion.

Do custom lock sounds work with Tesla's mobile app?

Yes, custom lock sounds will play when you lock your Tesla using the mobile app, key fob, or by walking away with your phone (if auto-lock is enabled).
