FAQ

Does the 2024 Model 3 refresh support custom lock sounds?

Yes. The 2024+ Model 3 (Highland refresh) fully supports custom lock sounds through the Boombox feature. All production units include the external pedestrian speaker hardware required. You need software version 2020.48 or later, which all 2024 units already exceed.

What audio settings work best for the 2024 Model 3's updated speakers?

Use WAV format at 44.1kHz, 16-bit PCM. The refreshed Model 3's speakers are more sensitive than previous generations, so normalize peak volume to -6dB rather than the standard -3dB. Mid-range frequencies (1–5kHz) reproduce best — avoid heavy bass-only sounds.

Can I use the same LockChime.wav from my old Model 3 on the new one?

Yes. The file format and folder structure (USB drive → Boombox folder → LockChime.wav) are identical across all Model 3 generations. Just copy your existing file to the USB drive and it will work. You may want to lower the volume slightly since the new speakers are louder.

Which USB port should I use on the 2024 Model 3?

Use the front USB-A port in the center console — it's the most reliable for custom sound detection on the refreshed Model 3. The USB-C ports can work, but the A port has the best track record. Format the drive to FAT32 or exFAT before use.

Where do I find the custom lock sound option on the 2024 Model 3 touchscreen?

Go to Controls → Safety & Security → Sentry Mode, then look for the Custom Sound or Lock Chime option. Your USB drive must be inserted for the option to appear. If you don't see it, make sure Sentry Mode is enabled first.
