Tesla Lock Sound

Tesla Model 3 (Pre-2019) lock sounds: not supported

No. Model 3 cars built before September 2019 don’t have the external speaker that a custom lock sound plays through. Check first: does Toybox → Boombox → Lock Sound exist in your car? See the full Model 3 install guide for what to look for.

Frequently asked questions

Does my Model 3 (Pre-2019) support custom lock sounds?

No. Model 3 cars built before September 2019 don’t have an external pedestrian-warning speaker, and custom lock sounds play through it.

How do I check whether my Model 3 has the external speaker?

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 does a supported Model 3 need?

It needs a WAV file named LockChime.wav at Boombox/LockChime.wav on a FAT32 or exFAT drive. In the car, open Toybox → Boombox → Lock Sound, then choose USB. Custom lock sounds need software 2023.44 or later. If you don’t see the Lock Sound option, update your software from Controls → Software.
