Change the stock Tesla lock chime without touching audio settings or editors
Replace the default beep with a custom file, keep the install path simple, and choose from 1,670+ Tesla-ready sounds that already download as LockChime.wav.
What it is
The lock chime is the short sound Tesla plays when the car locks or unlocks
By default, it is the same simple electronic beep every Tesla owner already knows. With the Boombox lock sound setting, you can swap that out for a different clip and make the car feel more specific to you without changing anything else in the install flow.
The custom sound still needs to respect Tesla's file rules, but once the file is in place the experience is straightforward: lock the car, hear the new sound, and move on.
