Tesla Lock Sound — The Complete Guide (2026)
Your Tesla's lock sound is the single most personalizable thing about your car. Every Model 3, Model Y, Model S, Model X, and Cybertruck shipped since 2020 can play a custom audio file when you lock or unlock the doors — if you know where to put it.
This guide covers everything: what a Tesla lock sound is, how to change it, where to download free ones, how to fix problems, and which sounds Tesla owners love most.
What Is a Tesla Lock Sound?
A Tesla lock sound is the audio chime your car plays when you lock or unlock the doors using the key fob, phone key, or NFC card. By default, Teslas play a short horn-like beep — functional, but not exactly exciting.
Since firmware 2022.x, Tesla's Boombox feature lets you replace that default beep with any audio file formatted as a 44.1kHz, 16-bit mono WAV file named LockChime.wav. Put it on a USB drive, plug it into your car, enable it in Boombox settings, and your car now plays your custom sound every time you walk away or come back.
Key specs your lock sound file needs:
| Requirement | Value |
|---|---|
| File name | LockChime.wav |
| Sample rate | 44,100 Hz |
| Bit depth | 16-bit |
| Channels | Mono (1 channel) |
| Max duration | 5 seconds (Tesla cuts off longer files) |
| File format | WAV (uncompressed PCM) |
| Location | USB drive → Boombox folder |
Every sound in our library is already pre-formatted to these exact specs — no conversion needed.
How to Change Your Tesla Lock Sound
Changing your lock sound takes about 2 minutes. Here's the step-by-step:
Step 1: Pick a Sound
Browse the Tesla Lock Sound library — 950+ free WAV files organized by category: gaming sounds, movie quotes, memes, sci-fi, nature, sports, and more. Click the play button on any sound card to preview it before downloading.
Popular picks include:
Step 2: Download the File
Click the download button on any sound card. The file downloads as LockChime.wav — already in the right format, already at the right sample rate, already named correctly. No conversion, no renaming, no sample rate math.
Step 3: Copy to USB
Format a USB drive as FAT32 or exFAT (see our USB formatting guide if you need help). Create a folder called Boombox in the root of the drive. Copy LockChime.wav into that folder.
Your USB structure should look like:
USB Drive (FAT32 or exFAT)
└── Boombox/
└── LockChime.wav
Step 4: Enable in Your Tesla
- Plug the USB drive into one of your car's USB-C ports
- Tap Controls → Safety & Security → Boombox (or Controls → Settings → Boombox on newer firmware)
- Toggle "Custom Lock/Unlock Sound" on
- Your custom sound plays immediately on the next lock/unlock
No restart needed. The change is instant.

Common Tesla Lock Sound Problems (And Fixes)
Lock Sound Not Changing
If your custom sound doesn't play after setup, check these in order:
- File name is wrong — it must be exactly
LockChime.wav(case-sensitive on some firmware versions) - Folder name is wrong — it must be
Boomboxin the root of the USB drive - USB format is wrong — your drive must be FAT32 or exFAT, not NTFS or APFS
- File format is wrong — must be 44.1kHz 16-bit mono WAV, not MP3 or AAC
- Boombox not enabled — check Controls → Safety → Boombox is toggled on

Lock Sound Too Quiet
If your custom sound is barely audible, the audio file itself might have low peak amplitude. WAV files recorded at low volume will play quietly through the Tesla speaker system.
Fix: Download a sound with proper normalization — all sounds in our library are peak-normalized to -1 dB for maximum clarity. For a deeper fix, see Why Is My Tesla Lock Sound So Quiet?
Lock Sound Stopped After a Software Update
Tesla's 2026.8 update changed Boombox settings for some models. If your custom sound stopped after an update:
- Re-enable Boombox in Settings
- Re-insert the USB drive
- If it still doesn't work, re-format the USB as FAT32 and re-copy the file

Custom Sound Plays for Lock but Not Unlock
This happens when the file is longer than 5 seconds. Tesla plays the full file for lock but cuts unlock short. Keep your sound under 5 seconds for consistent playback both ways.

Which Teslas Support Custom Lock Sounds?
| Model | Year | Custom Lock Sound |
|---|---|---|
| Model 3 | 2021+ | Yes (Boombox) |
| Model Y | 2020+ | Yes (Boombox) |
| Model S | 2021+ | Yes (Boombox) |
| Model X | 2021+ | Yes (Boombox) |
| Cybertruck | 2024+ | Yes (Boombox) |
| Model 3 Highland | 2024+ | Yes (Boombox) |
| Original Model S/X | Pre-2021 | No (no Boombox) |
If your car has the Boombox feature in Settings, it supports custom lock sounds. If you don't see Boombox, your firmware or hardware doesn't support it yet.
How to Create Your Own Tesla Lock Sound
Want something that isn't in the library? You can make your own:
- Record or find any audio clip (MP3, WAV, M4A — doesn't matter)
- Trim it to 5 seconds or less
- Convert to WAV — 44.1kHz, 16-bit, mono
- Rename to
LockChime.wav - Normalize volume — peak at -1 dB so it plays loud enough through your Tesla speakers
Free tools that work: Audacity (desktop), ffmpeg (command line), or any online WAV converter. Full step-by-step: How to Create Your Own Tesla Lock Sound

Frequently Asked Questions
Can I have different lock and unlock sounds?
No. Tesla uses one LockChime.wav file for both locking and unlocking. You can't set separate sounds — the same file plays for both actions.
Will my custom lock sound work after a Tesla software update?
Usually yes, but some major updates (like 2026.8) can reset Boombox settings. After any update, check that Boombox is still enabled and your USB is still plugged in.
Can I use an MP3 file as my lock sound?
No. Tesla only reads WAV files. If you have an MP3, convert it to 44.1kHz 16-bit mono WAV first, and name it LockChime.wav.
Do custom lock sounds drain the battery?
No. The audio plays through the external speaker for about 5 seconds. The energy draw is negligible — comparable to a single door lock cycle.
Can I use the same USB drive for dashcam and lock sounds?
Yes. Tesla reads dashcam from the TeslaCam folder and Boombox from the Boombox folder. They can coexist on the same drive. See our USB formatting guide for the full partition structure.
What's the best Tesla lock sound?
Depends on your style. The Vine Boom is the most downloaded overall. The Imperial March is the most popular sci-fi sound. Browse the full library sorted by "Most Downloaded" to see what other Tesla owners picked.
Can I change my Tesla Sentry Mode sound too?
Yes — Sentry Mode has its own custom sound option. It uses a different file and settings path. See our Sentry Mode sound guide.
