How To Install

Tesla uses two completely separate systems for custom sounds — Lock Chime and Boombox. They need different USB setups.

Lock Chime

Plays on lock / unlock
FilenameLockChime.wav
USB location/ (root — no subfolder!)
FormatWAV, uncompressed PCM
Recommended44.1 kHz or 48 kHz · 16-bit · Mono
Max size1 MB
USB formatexFAT or FAT32

Boombox Sounds

Horn · AVAS · Summon
FilenameAny name — no spaces or accents
USB location/Boombox/ folder
FormatMP3 or WAV
Max files5 files (alphabetical order)
USB formatexFAT only (NTFS not supported!)
Horn only works in Park — NHTSA rules revert it to stock while driving
Lock Chime and Boombox cannot share the same USB partition.

Use two separate USB drives — or partition one drive. Mixing them on the same partition will cause one or both systems to fail.

Lock Chime — Step by Step
01

Download the sound

Your file downloads automatically as LockChime.wav — exact capitalisation required. Do not rename it.

02

Format the USB drive

Format as exFAT or FAT32. Copy LockChime.wav directly to the root — not inside any folder.

03

Plug into Tesla & test

Insert the USB into the glovebox port. Lock your Tesla — it should play within a few seconds. No Boombox menu needed for Lock Chime.

Boombox (Horn / AVAS / Summon) — Step by Step
01

Download the sound

Your file downloads as a .wav. Rename if needed — avoid spaces and special characters.

02

Prepare the USB drive

Format as exFAT. Create a folder named exactly Boombox in the root. Copy up to 5 sound files into it.

03

Assign in Tesla

Go to Controls → Safety → Boombox. Select the sound for Horn, AVAS, or Summon.

04

Test each sound

Horn works in Park only. AVAS plays at low speed. Summon plays during Smart Summon movement.

All Lock-A-Tone files are Tesla-ready out of the box.

Every sound is pre-exported in the exact format and filename Tesla expects. Compatible with Model 3, Y, S, and X.
