Software Requirements
Custom lock sounds require:

- Sentry Mode: Required for lock sound customization
Check your version: Controls > Software
Installation Steps
1. Verify Compatibility
Before proceeding:
- Check software version (2023.44 or later)
- Verify Sentry Mode is available
- Confirm external speakers are installed
2. Prepare USB Drive
Format to FAT32 or exFAT:
- Windows: Right-click > Format > FAT32
- Mac: Disk Utility > Erase > MS-DOS (FAT)
3. Create Folder Structure
USB Drive/
└── Boombox/
└── LockChime.wav
4. Audio Requirements
- Format: WAV
- Sample Rate: 44.1kHz
- Bit Depth: 16-bit
- Duration: 1-5 seconds
- Peak Volume: just under 0 dB (the converter's ceiling is -1 dB)
5. Install on Your Tesla
- Insert USB into a USB port that carries data (the glovebox port on newer cars)
- Go to Toybox → Boombox → Lock Sound
- Choose USB
- Select your sound file
> Boombox menu missing? Custom lock sounds need the external pedestrian-warning speaker: Model 3 built September 2019 or later, Model S and X from the 2021 refresh, and every Model Y and Cybertruck, plus software 2023.44 or later. Cars without it won't show the option. See how to get custom sounds in any region.

Optimization for Older Hardware
Pre-2024 Teslas may have slightly different speaker characteristics:
Audio Tips
- Keep sounds simple and clear
- Avoid excessive bass (speakers are smaller)
- Lower the level if the sound distorts
- Shorter sounds (1-2 seconds) recommended
File Tips
- Use smaller file sizes (<500KB)
- Stick to mono or simple stereo
- Avoid complex reverb effects
Troubleshooting Legacy Models
"Custom Sound Not Available"
- Update software to latest version
- Check regional availability of Boombox
- Verify Sentry Mode is enabled
USB Not Detected
- Try another USB port that carries data
- Try FAT32 format (not exFAT)
- Use a simpler, smaller USB drive
Sound Quality Issues
- Re-export at exactly 44.1kHz, 16-bit
- Check audio levels
No External Speakers
For pre-2020 vehicles without external speakers:
- Contact Tesla service center
- Speaker retrofit may be available
- Check owner's manual for specifications

FAQ
Do pre-2024 Tesla models support custom lock sounds?
Yes, if the car has the external pedestrian-warning speaker: Model 3 built September 2019 or later, every Model Y, and Model S and X from the 2021 refresh, on software 2023.44 or later. The setup is identical to newer models: FAT32 USB drive, Boombox folder, LockChime.wav.
What's the minimum software version needed for custom sounds on older Teslas?
Software 2023.44 or later is required for the custom Lock Sound menu. To check your version, go to Controls → Software. If you're on an older version, connect to WiFi and install the latest update.
My 2019 Model 3 doesn't show the custom sound option. Why?
The 2017–2019 Model 3 may not have had external pedestrian warning speakers installed. Check whether Toybox → Boombox → Lock Sound offers a USB option. If it's not there with current firmware, your vehicle may need a speaker retrofit: contact Tesla Service to confirm.
What audio optimization should I apply for pre-2024 Tesla speakers?
Keep sounds simple and clear, avoid heavy bass content, and keep duration short for best daily-use comfort. We don't have a source comparing the speakers across years.
Will the custom sound feature work the same on my 2022 Model Y as on a 2025 Model Y?
The feature is functionally identical: same USB setup, same folder structure, same file naming. The 2025 has a slightly better external speaker, so the same file may sound slightly fuller on the newer model, but the process and compatibility are the same. Any sound from our library works on both.
