Tesla Model X Lock Sound: Install Guide

Model X uses the same Boombox/LockChime.wav workflow as Model S. The platform difference that matters for installs: the 2021+ refresh shifted the center-console port from USB-A to USB-C, and pre-September-2019 vehicles lack the external Pedestrian Warning Speaker required for lock chimes.

Quick spec

File path: Boombox/LockChime.wav
USB filesystem: FAT32 or exFAT
Port (2021+ refresh): Center-console USB-C
Port (2015–2020): Center-console USB-A
Hardware requirement: PWS (Sept-2019+ standard)
Software floor: 2023.44.25+

Steps

Download a sound

Pick from the library, or generate one with AI voice. Save the .wav locally.

File must end in .wav. Filename is set automatically.

Format your USB

FAT32 or exFAT. Any size works, even 64 MB. Empty stick recommended.

macOS: Disk Utility → Erase → MS-DOS (FAT). Windows: right-click → Format → FAT32.

Make a /Boombox folder

Create one folder named exactly Boombox at the USB root. Capital B, case-sensitive.

No subfolders. Place LockChime.wav directly inside Boombox/.

Drop the WAV in /Boombox/

The file must be named exactly LockChime.wav. It is the only name Tesla recognizes.

One LockChime.wav at a time. Exact filename required.

Plug into a front USB port

Model 3/Y: front console port (USB-C on newer builds, USB-A on older). S/X and CT: center console.

Must be a data port. Rear ports are power-only.

Model X port note

2021+ refresh: center-console USB-C. Legacy 2015–2020: center-console USB-A. Falcon-wing door electronics share the cabin bus but do not affect Boombox routing. Verify the Pedestrian Warning Speaker (PWS) is present: pre-September-2019 cars without it cannot play audio outside the cabin.

Lock the car

Walk away or hit the key fob. Your sound plays through the external speaker.

No sound? Toybox → Boombox → Lock Sound → enable + select file.

FAQ

Do the falcon-wing doors affect lock sound playback?

No. The falcon-wing doors share the Model X cabin electrical bus but are not on the Boombox audio path. The lock chime always plays through the external Pedestrian Warning Speaker mounted at the front of the car.

Does my pre-2019 Model X support custom lock sounds?

Pre-September-2019 Model X vehicles shipped without the external PWS. If your Model X is older and never went through a PWS retrofit, Boombox cannot play audio outside the cabin, even with the correct file and software.

Where's the Model X USB data port?

Center console, front-facing. USB-C on 2021+ refresh, USB-A on 2015–2020 legacy. Rear console ports are power-only.
