Tesla Custom Chime: How to Download & Install Your Own Lock Sound

Your Tesla's lock chime plays every time you walk away from the car. After a few months, the stock sound fades into background noise — you barely notice whether you actually locked it. A custom Tesla chime fixes that: one recognizable sound you'll never miss, every single time.

This guide covers everything: where to find a tesla custom chime download, how to prepare the USB, and the exact steps to activate it. The install takes about five minutes.

What Is a Tesla Custom Chime?

Tesla lets you replace the default lock sound with any WAV audio file you choose. When you lock your car — via the app, the key card, or by walking away — your Tesla plays your file through its external speakers instead of the factory tone.

Tesla calls the feature Lock Chime (found under Controls → Safety → Customize Lock Sound). Internally, the file must be named LockChime.wav and placed inside a Boombox folder on a USB drive. That's it. No jailbreak, no firmware modification — it's an official Tesla feature.

Step 1: Find and Download Your Tesla Custom Chime

Start at the Tesla Lock Sound library. Every sound is free to preview in your browser — click play on any card to hear exactly what it'll sound like through your car's external speakers before you commit.

Browse by category to narrow it down:

When you find one that makes you smile, click Download. The file downloads as LockChime.wav — already named correctly, already formatted to Tesla's 44.1kHz/16-bit WAV spec. No Audacity, no conversion needed.

Step 2: Prepare Your USB Drive

Tesla reads USB drives formatted as FAT32 or exFAT. NTFS (Windows default) and APFS (Mac default) will not work. If you're not sure what format your drive is, reformat it:

A cheap 4GB drive works perfectly. You don't need a high-speed drive for a single WAV file.

Step 3: Add the Chime File to Your USB Drive

Create the exact folder structure Tesla expects:

USB Drive (root)
└── Boombox/
    └── LockChime.wav

The folder must be named Boombox (capital B, no spaces). The file must be named LockChime.wav exactly. Tesla won't recognize any variation — lockchime.wav, LockChime (1).wav, or LOCKCHIME.WAV will all fail. If you downloaded from this site, the filename is already correct.

Step 4: Activate Your Custom Tesla Chime

1. Plug the USB drive into your Tesla's front center console USB-A port (or USB-C on Model Y Juniper / Cybertruck — use an adapter if needed)
2. Wait about 10 seconds for Tesla to detect the drive
3. On the touchscreen, go to Controls → Safety → Customize Lock Sound
4. Select your LockChime.wav file from the list
5. Tap Done to confirm

Lock your Tesla from the app or by walking away — your custom chime plays immediately.

If the sound doesn't appear in the menu, double-check the folder name (Boombox, not boombox or BOOMBOX) and the file name (LockChime.wav, not lockchime.wav). Reformat the USB as FAT32/exFAT if the menu shows the drive but not the file. See the full installation guide for model-specific USB port locations and firmware-related troubleshooting.

Picking the Right Custom Chime

The best Tesla lock chimes share three traits: short (under 2 seconds — long enough to register, short enough to not annoy neighbors), instantly recognizable (you hear it and know you locked), and well-normalized (audible from 20 feet away without clipping).

Every sound in our library is pre-trimmed and volume-normalized to Tesla's 60–85 dB external speaker range. The sound library has 1,670+ options — browse by category, preview in-browser, and download the one that fits your car's personality.

FAQ

What file format does Tesla use for a custom lock chime?

Tesla requires a WAV file (PCM, uncompressed) at 44.1kHz sample rate, 16-bit depth. The file must be named LockChime.wav exactly. All sounds downloaded from TeslaLockSound.com are already in the correct format — no conversion needed.

Where does the LockChime.wav file go on the USB drive?

Inside a folder named Boombox at the root of the USB drive. The full path is /Boombox/LockChime.wav. The folder name is case-sensitive.

Does a custom Tesla chime work on all models?

Yes — Model 3 (2019+), Model Y (all years), Model S and X (2021 refresh+), and Cybertruck all support the Boombox Lock Chime feature. Older Model S and X vehicles do not have external speakers for this feature.

How do I switch to a different custom chime?

Replace the LockChime.wav file on your USB drive with a new one, plug the drive back in, go to Controls → Safety → Customize Lock Sound, and re-select the file. You can keep multiple options on the drive in subfolders and swap them any time.

My Tesla isn't playing the custom chime. What's wrong?

Check these in order: (1) folder named exactly Boombox, (2) file named exactly LockChime.wav, (3) USB formatted as FAT32 or exFAT (not NTFS), (4) Lock Chime feature enabled in Controls → Safety. If it still doesn't work, see the troubleshooting guide.

Is downloading a custom Tesla chime free?

Yes — every sound on TeslaLockSound.com is free. Preview in your browser at /sounds, download with one click, no account required.
