Custom lock sound not working? Fixes that actually help

The car plays the old sound, the USB option is greyed out, or nothing happens. Here is what to check, in order.

Work through these in order. Most problems are solved by the first three.

The car still plays the old sound

The car keeps its own copy of the lock sound from the last time you selected USB. Replacing the file on the drive isn’t enough: open Toybox → Boombox → Lock Sound, switch to another sound, then back to USB. That makes the car read the new file.

The USB option is missing or greyed out

  • Check the file name. It must be exactly LockChime.wav. Windows may hide the extension and you end up with LockChime.wav.wav; turn on View → File name extensions to check.
  • Check the location. The file must be at the top level of the drive, not in a folder (and not inside TeslaCam).
  • Check the size. It must be under 1 MB. Every file from this site is, at every volume.
  • Check the drive format. exFAT or FAT32 work. NTFS (common on Windows-formatted drives) and APFS (Macs) don’t.
  • Try another port. On some cars only certain ports carry data. The glovebox port and the centre-console ports are the usual ones.

Nothing plays at all when locking

  • Make sure Lock Confirmation Sound is turned on under Controls → Locks.
  • Some cars only play the lock sound when you walk away with your phone key or lock from the app, not with every lock method.
  • Very early cars without an external speaker can’t play custom sounds. If you don’t see Boombox in the Toybox, yours doesn’t have one.

The sound is too quiet or too loud

The car doesn’t offer a volume control for the lock sound, so download the same sound again at a different volume setting. Loud and Max raise the level and smoothly limit the peaks so they don’t distort.

The sound is cut off

Long sounds may be trimmed by the car. Everything in this library is five seconds or shorter for that reason.
