How to install a custom Tesla lock sound in two minutes
One WAV, one folder, one Toybox toggle. The format is picky. The steps are not.
Tesla plays a single file when you lock the car: LockChime.wav. There is no UnlockChime. The factory unlock tone stays factory. Your custom file is the lock event only.
Format: uncompressed PCM WAV, 44.1 kHz, 16-bit, mono or stereo, about 1–5 seconds. Name it exactly LockChime.wav. Put it in a folder named Boombox at the root of a FAT32 or exFAT USB stick. Path: Boombox/LockChime.wav. NTFS and APFS will not work.
Plug into a front USB data port — rear ports are often power-only. If the car does not see the drive, try the glovebox data port. Then: Toybox → Boombox → Lock Sound → USB. If you still hear the Light Cycle chime, the file is not a real WAV, the folder name is wrong, or Boombox is not set to USB.
Every sound in the TG29 library is already Tesla-ready. Download, copy, plug in. Full walkthrough lives in Lock sounds.
