/ 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. Filename is set automatically.

Format your USB

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

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

Make a /Boombox folder

Create one folder named exactly Boombox at the USB root. Capital B, case-sensitive.

No subfolders. Place LockChime.wav directly inside Boombox/.

Drop the WAV in /Boombox/

The file must be named exactly LockChime.wav. It is the only name Tesla recognizes.

One LockChime.wav at a time. Exact filename required.

Plug into a front USB port

Model 3/Y: front console port (USB-C on newer builds, USB-A on older). S/X and CT: center console.

Must be a data port. Rear ports are power-only.

Lock the car

Walk away or hit the key fob. Your sound plays through the external speaker.

No sound? Toybox → Boombox → Lock Sound → enable + select file.
/ pre-flight

Driveway-Grade Pre-Flight Checklist

60-second check before you walk to the car. Catches 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.

More detail: LockChime.wav installer, USB format guide, 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. Path: USB Drive/Boombox/LockChime.wav

FAT32 vs exFAT USB walkthrough.

Common mistake: wrong folder

LockChime.wav must go inside the Boombox folder, not the USB root. Boombox/LockChime.wav.

Confirm before you leave your desk

Open the USB and confirm one file at Boombox/LockChime.wav. Catches almost every install issue.

Step 3: Connect to Tesla

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

Port layout varies by model year

If the first port doesn't show USB in Boombox, try the other front or glovebox data port before changing files.

Step 4: Activate in Tesla Settings

  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!

First-lock test

  1. Step out and lock once with the app or key card.
  2. Hear your clip? Done.
  3. Still playing Light Cycle? Re-check file path and filename, then see the 7-fix troubleshooting guide.

Tesla Model/Year Install Confidence Matrix

Confidence levels are conservative and source-linked.

Hardware requirement: external speaker

Lock sounds play through the Pedestrian Warning Speaker (PWS). Model Y and Cybertruck include it on every unit. Model 3 needs a September 2019 or later build. Model S and Model X need the 2021 refresh. Not sure? Open Toybox → Boombox. If it appears, you have the speaker. Full eligibility FAQ.

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 front data port on your Tesla, then go to Toybox → Boombox → Lock Sound → USB.

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 WAV format (44.1kHz, 16-bit PCM), named exactly LockChime.wav, inside a Boombox folder on a FAT32 or exFAT USB drive. Keep files 1–5 seconds. All 1,053+ sounds on TeslaLockSound 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 (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 1–5 seconds. Longer sounds may be cut off. All sounds in the library are within that range.

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 TeslaLockSound files safe for my Tesla?

All files use Tesla's specified format (44.1kHz, 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.
