Tesla Cybertruck Custom Sounds: Complete Guide for 2026
The Cybertruck is the most talked-about Tesla ever built, and its exterior speaker system is the best in Tesla's lineup. Custom lock sounds on a Cybertruck aren't just a fun novelty—they're a statement. This guide covers everything you need to know to set up the perfect sound for your stainless steel truck.
Why the Cybertruck's Sound System Is Different
Before getting into specific sounds, it's worth understanding what makes the Cybertruck's audio setup unique.
The Cybertruck ships with multiple high-output external speakers, a more powerful amplifier stage than other Tesla models, and a speaker placement optimized for the truck's larger, taller body. What this means in practice: sounds that play quietly on a Model Y sound big on a Cybertruck. Bass-heavy sounds reproduce cleanly. You have room to be bold.
This is why generic "any Tesla" sound lists don't give Cybertruck owners the full picture. Your truck can handle sounds that would clip or sound thin on smaller models.
Cybertruck Compatibility
Every Cybertruck delivered since the 2023 launch supports the full custom sound feature set:
No retrofitting, no waiting for a software update, no model-year caveats. If you have a Cybertruck, you have full support out of the box.
Required software version: 2023.38 or later (all current Cybertrucks exceed this).
How to Install Custom Sounds on Your Cybertruck
Step 1: Get a USB Drive
Any standard USB drive works. Format it to FAT32 (recommended) or exFAT. 32GB or smaller is most reliable, though larger drives work fine.
Step 2: Create the Folder Structure
On the root of your USB drive, create exactly this structure:
USB Drive/
└── Boombox/
└── LockChime.wav
The folder must be named exactly "Boombox" and the file must be named exactly "LockChime.wav" — Tesla won't recognize anything else.
Step 3: Get Your Sound File
Download any sound from our Cybertruck collection — every file is already formatted correctly (WAV, 44.1kHz, 16-bit). Rename it to LockChime.wav if needed.
If you want to use a sound from another source, run it through our audio converter first. It handles format conversion, volume normalization, and trims to the right length automatically.
Step 4: Install on Your Cybertruck
- Insert the USB drive into any Cybertruck USB port (center console or front passthrough both work)
- On the touchscreen, tap Controls
- Navigate to Safety & Security
- Tap Sentry Mode
- Look for Custom Sound or Lock Chime option
- Select your sound from the USB
Step 5: Test It
Lock your Cybertruck from the app or key card. You should hear your new sound. If you don't, see the troubleshooting section below.
Best Lock Sounds for the Cybertruck
The Cybertruck's speaker system rewards sounds with character. Here are the categories and specific picks that work best.
Industrial & Mechanical
The Cybertruck's angular stainless steel design pairs naturally with industrial sounds. Heavy machinery hisses, hydraulic actuators, metal impact sounds—they all land differently on a truck that looks like it belongs on a factory floor.

Sci-Fi & Futuristic
The Cybertruck is the closest thing to a movie spaceship you can legally drive on public roads. Lean into it.

Cybertruck-Specific Sound Tips
Take Advantage of the Bass
Unlike the Model 3 or Model Y, the Cybertruck handles low-frequency content well. Sounds with bass components—Vine Boom, hydraulic effects, cinematic stings—sound significantly better on a Cybertruck than on smaller models.
Volume Calibration
The Cybertruck's speakers are powerful. If you convert your own sound using our converter, aim for a peak of -3dB rather than the standard -6dB recommendation for other models. You'll get more impact without distortion.
The Aesthetic Matters
You've chosen one of the most visually distinctive vehicles ever built. Your lock sound is an extension of that. A soft piano chord might be great on a Model S, but it's a missed opportunity on a Cybertruck. Match the truck's personality.
Consider Your Environment
Cybertruck speakers are loud enough that sounds carry. If you live in a dense neighborhood or park in shared spaces, test your chosen sound at close range before committing. A dramatic bass drop at 11 PM can cause issues with neighbors.
For Boombox Mode
Beyond lock sounds, the Cybertruck's Boombox mode is exceptional. You can store multiple WAV files in the /Boombox/ folder and play them through the external speakers from the touchscreen.
This makes your Cybertruck ideal for:
Any file in the Boombox folder (besides LockChime.wav) can be played manually. The folder supports multiple files, and you can switch between them from the Boombox interface.
