Frequently asked questions
Does my Model 3 (2019–2021) support custom lock sounds?
It depends on the build. A Model 3 has an external pedestrian-warning speaker only if it was built from September 2019 on, and custom lock sounds play through it. Check first: does Toybox → Boombox → Lock Sound exist in your car? If it does, you are set. If it does not, update your software from Controls → Software, then look again. If it still is not there, your car likely predates the external speaker.
What software version do I need on my Model 3?
Custom lock sounds need software 2023.44 or later. If you don’t see the Lock Sound option, update your software from Controls → Software.
Which USB port should I use on the Model 3?
Use a USB port that carries data. On newer cars that is the glovebox port; the rear ports only charge.
Are the WAV files on this page safe for my Tesla?
Every file is a WAV named LockChime.wav, encoded to the recommended settings: 44.1 kHz, 16-bit, under 1 MB. Tesla requires only the WAV format and the filename. The file is a plain audio clip: it changes the lock sound and nothing else.
