FAQ
Do pre-2024 Tesla models support custom lock sounds?
Yes. All Model 3 and Model Y from 2020 onward, and Model S and Model X from 2020 onward (with 2020.48+ software), support custom lock sounds. The setup process is identical to newer models — FAT32 USB drive, Boombox folder, LockChime.wav. The main variable for older vehicles is whether external speakers were installed.
What's the minimum software version needed for custom sounds on older Teslas?
Version 2020.48 or later is required for the Boombox/custom lock sound feature. To check your version, go to Controls → Software. All vehicles currently receiving updates exceed this minimum. If you're on an older version, connect to WiFi and download the latest available update.
My 2019 Model 3 doesn't show the custom sound option — why?
The 2017–2019 Model 3 (pre-mid-range and early Standard Range models) may not have had external pedestrian warning speakers installed. Check under Controls → Safety & Security → Sentry Mode for the Custom Sound 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?
Pre-2024 models have smaller, lower-output external speakers compared to 2024+ models and the Cybertruck. Keep sounds simple and clear, normalize to -6dB, avoid heavy bass content, and keep duration under 2 seconds for best daily-use comfort. Mono files work well since the single-speaker setup won't benefit from stereo.
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.
