Model-Specific Install Help
GETTING STARTED
Getting Started

Is TeslaLockSound free to use?
Yes. Every sound in the library is free to download.
Do I need special software to use these sounds?
No. You need a USB drive to transfer the file. The rest uses Tesla's built-in audio customization feature.
Is TeslaLockSound affiliated with Tesla?

SOUND FILES
Sound File Formats & Specs
What audio format do Tesla lock sounds need to be?
A WAV file named exactly LockChime.wav. For clean playback, 44.1kHz sample rate, 16-bit depth, 1–5 seconds, and under 1MB. Every sound on TeslaLockSound (and anything from our converter) already follows these settings.
How long should a lock sound be?
1–5 seconds. Shorter (1–2 s) works best for daily use; Tesla may not play sounds that exceed 5 seconds.
Can I convert my own audio files?
Yes. Our free converter at teslalocksound.com/convert handles conversion, naming, trimming, and volume in your browser. All sounds on TeslaLockSound are already correctly named and formatted, no conversion needed.
What is the ideal volume level for lock sounds?
Normalize audio to peak at -3dB to -6dB for clear playback without distortion. TeslaLockSound files are already formatted within this range.
Can I use MP3 files for Tesla lock sounds?
No. Tesla only plays WAV files. MP3 will not work. Our free converter at teslalocksound.com/convert turns any MP3 into a Tesla-ready LockChime.wav in your browser (trim, volume, and fades included). All sounds on TeslaLockSound are already in the correct WAV format.
What's the maximum file size for lock sounds?
Tesla doesn't publish an official limit, but keep sounds under 1MB. Files at 1–5 seconds typically fall well within that; larger files may take longer to load or cause playback issues.
Is 24-bit audio supported for Tesla lock sounds?
16-bit WAV is recommended. 24-bit files often fail to play or behave unpredictably. If you have a 24-bit file, run it through teslalocksound.com/convert or export 16-bit WAV from any audio editor. All TeslaLockSound files are already 16-bit.
What audio software do you recommend for editing Tesla sounds?
Our free editor at teslalocksound.com/convert trims, fades, sets loudness, and exports a Tesla-ready LockChime.wav in the browser. For a desktop app, Audacity (free, audacityteam.org) and GarageBand (Mac) both export 44.1kHz 16-bit WAV.
INSTALLATION
Installing Custom Lock Sounds
How do I install a custom lock sound on my Tesla?
Place LockChime.wav inside a "Boombox" folder on a FAT32 or exFAT USB drive (path: Boombox/LockChime.wav), insert the USB into your Tesla, then navigate to Toybox → Boombox → Lock Sound → USB. See our step-by-step guide for full details.
What file system should my USB drive use?
FAT32 or exFAT. NTFS drives may not be recognized by Tesla's infotainment system.
Does the folder structure matter?
Yes. Create a folder called "Boombox" on the root of your USB drive and put "LockChime.wav" inside it. Path: Boombox/LockChime.wav
Can I have multiple custom sounds?
Tesla plays exactly one custom lock sound: Boombox/LockChime.wav on your USB drive. Keep multiple sounds in other folders and swap by copying a different file into Boombox/ as LockChime.wav. There is no in-car picker. The "USB swap pack" download on your saved-sounds page packages this for you.
How long does it take to install a custom lock sound?
About 5–10 minutes: download the sound, copy it to a USB drive in the correct folder, insert the USB, and select it in Tesla settings. The sound plays immediately once selected.
Can I transfer sounds to my Tesla via Bluetooth or WiFi?
No. Custom lock sounds require a USB drive formatted as FAT32 or exFAT, with the file at Boombox/LockChime.wav. Wireless transfer is not supported.
TROUBLESHOOTING
Troubleshooting Lock Sound Issues
My custom sound isn't playing. What should I check?
Verify the file is named exactly LockChime.wav inside a Boombox folder (path: Boombox/LockChime.wav), the file is WAV format (44.1kHz, 16-bit), and the USB is formatted as FAT32 or exFAT. Try a different USB port or drive, then re-select the sound under Toybox → Boombox → Lock Sound → USB.
The sound is distorted or too quiet. How do I fix it?
Distortion means the level is too hot; too quiet means it needs normalizing. Open the sound in our editor at teslalocksound.com/convert and use the Quiet/Normal/Loud presets. They normalize loudness with a built-in clipping guard. Or download a pre-optimized sound from TeslaLockSound.
My sound stopped working after a software update.
Updates can reset custom sound settings. Re-insert your USB and re-select your sound under Toybox → Boombox → Lock Sound → USB. Your file should still be compatible.
Tesla doesn't recognize my USB drive. What should I do?
Format to FAT32 or exFAT (NTFS is not supported). Try a different USB port or drive, and confirm the folder is named exactly Boombox and the file is named exactly LockChime.wav.
How do I revert to the default Tesla lock sound?
Go to Toybox → Boombox → Lock Sound and select "Default". Alternatively, remove the USB drive containing your custom sound.
My lock sound stopped working after a Tesla software update. What do I do?
Updates can reset custom sound settings. Re-insert your USB and re-select your sound under Toybox → Boombox → Lock Sound → USB. If that fails, verify the file still meets requirements (WAV, 44.1kHz, 16-bit) and check our blog for any new compatibility notes.
Why is my Tesla lock sound too quiet?
The audio file likely has low levels. Open it in our editor at teslalocksound.com/convert and choose the Loud preset. It raises loudness with a clipping guard. Also confirm your Tesla's Boombox volume isn't turned down.
COMPATIBILITY
Tesla Model Compatibility
Does my Tesla have the speaker needed for custom lock sounds?
Custom lock sounds play through the external Pedestrian Warning Speaker (PWS). Model Y and Cybertruck have it on every unit. Model 3 built from September 2019 onward includes it; earlier units do not. Model S and X require the 2021 refresh or later. Quickest check: open Toybox → Boombox on your touchscreen. If Boombox appears, your car has the speaker. If it is missing, Tesla Service can confirm whether a hardware retrofit is possible for your VIN.
Which Tesla models support custom lock sounds?
Model 3 (built September 2019 or later), Model Y (all years), Model S and X (2021 refresh or later), and Cybertruck. The requirement is the external pedestrian-warning speaker. Tesla Service can retrofit some older vehicles without it.
Do I need a specific software version?
Custom lock sounds have been available since Tesla’s 2023 Holiday Update (software 2023.44), so virtually every Tesla on current software supports them. If you don’t see the Lock Sound option, update your software from Controls → Software.
Will custom sounds work with Sentry Mode?
Custom lock sounds (set via Toybox → Boombox → Lock Sound) play on lock and unlock events. Sentry Mode is a separate feature and does not share the custom lock sound setting.
Are these sounds compatible with the 2024 Model 3?
Yes, the 2024 Model 3 refresh supports custom lock sounds. TeslaLockSound files follow Tesla's audio specifications, but test to confirm after install.
FEATURES
Boombox & Custom Sound Features
Can I customize my Tesla horn sound too?
Yes. Tesla Boombox lets you add custom horn sounds to your USB drive alongside lock sounds. This replaces the Boombox horn only. The emergency safety horn is unchanged.
Does Tesla support different sounds for lock vs unlock?
No. Tesla plays LockChime.wav for both lock and unlock events. There is no way to set separate sounds for each action.
How does Sentry Mode work with custom sounds?
They are independent. Your custom lock sound (set via Toybox → Boombox → Lock Sound) plays on lock and unlock events. Sentry Mode uses a separate, non-customizable alarm and has no effect on custom lock sounds.
What is Tesla Boombox and how does it work?
Boombox uses your car's external pedestrian-warning speaker to play custom sounds: lock chimes, horn sounds, and audio while parked. Introduced in Tesla's 2020 Holiday Update; requires the external speaker (Model 3 from September 2019, Model Y and Cybertruck on all units, Model S/X from the 2021 refresh).
LEGAL & SHARING
Legal & Sharing
Can I share sounds I download from TeslaLockSound with friends?
Yes. All sounds are free to share with friends and family for personal use. Copy them to USB drives for other Tesla owners. Please don't redistribute them commercially or host them on other sites without permission.
Can I use copyrighted music as my Tesla lock sound?
Using copyrighted music without permission is legally risky, even for personal use. Short clips may fall under fair use in some jurisdictions, but it's a gray area. All sounds on TeslaLockSound are original creations or properly licensed for use as lock sounds.
