Replace the default beep with any sound you want. Works on Model 3, Y, S, X & Cybertruck — install in 2 minutes with a USB drive.
The lock chime is the short sound your Tesla plays when you lock or unlock your car. By default, it's a simple electronic beep — the same sound every Tesla makes. With the Boombox feature (available on all models from 2022+), you can replace it with any custom sound up to 5 seconds long.
The custom sound plays through your car's external speaker (the pedestrian warning speaker), so you hear it when you walk away and so does everyone nearby. It's the single most noticeable customization you can make — and it takes 2 minutes.
Pick any sound from our library of 950+ free chimes. Each one downloads as LockChime.wav — already in Tesla's format.
Browse sounds →Create a folder called "Boombox" on a FAT32 or exFAT USB drive. Place LockChime.wav inside it. The full path: Boombox/LockChime.wav
Insert the USB drive into your Tesla's front USB-C port (glovebox area on Model 3/Y, center console on S/X).
Go to Toybox → Boombox → Lock Sound → change from "Default" to "USB". Your custom chime plays immediately.
