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

Frequently asked questions
Does my Model S (Pre-2019) support custom lock sounds?
No. Model S cars built before the 2021 refresh don’t have an external pedestrian-warning speaker, and custom lock sounds play through it.
How do I check whether my Model S 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 S 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.
