Tesla Lock Sound Option Missing? What to Check

No Lock Sound option under Toybox → Boombox? It comes down to the external speaker and your software version. Here is how to check both.

Tips & tricks4 min read

You found a lock sound, opened Toybox, and there is no Lock Sound option. Two things decide whether it shows up: whether your car has the external speaker, and whether your software is new enough.

Custom lock sounds need the car’s external pedestrian-warning speaker (Model 3 built September 2019 or later, Model S and Model X from the 2021 refresh, every Model Y and Cybertruck) and software 2023.44 or later.

Check 1: Software

Custom lock sounds arrived with software 2023.44 or later. Open Controls → Software and install any pending update, then look again under Toybox → Boombox → Lock Sound.

Check 2: The external speaker

The custom lock sound plays through the external pedestrian-warning speaker. Cars without it do not show the option:

  • Model 3 built before September 2019
  • Model S and Model X from before the 2021 refresh (not confirmed either way; check the menu)

Tesla's documentation does not describe a way to play a USB lock sound through the cabin speakers on a car without the external speaker. If the option is missing after a software update, your car most likely does not have it. Tesla Service can confirm what your VIN was built with.

Check 3: Boombox while driving (US)

In the US, NHTSA recalls 22V-063 and 22V-235 (2022) led Tesla to disable Boombox when the car is in Drive, Neutral or Reverse, including Summon and Smart Summon. The lock sound plays when you lock the car, so it is a different use. If you cannot find the Boombox menu at all, work through checks 1 and 2 first. If your lock sound disappeared after an update, see lock sound resets after update.

If the option is there

  1. Format a USB drive as FAT32 or exFAT (USB format guide).
  2. Put LockChime.wav in a folder named Boombox, so the path is Boombox/LockChime.wav.
  3. Plug the drive into a USB port that carries data (the glovebox port on newer cars; rear ports only charge).
  4. Open Toybox → Boombox → Lock Sound, then choose USB.

If the car does not pick the file up from Boombox/, try putting LockChime.wav at the top level of the drive instead. Both locations work.

FAQ

Can I use custom lock sounds on a UK or EU Tesla?

Only if the car has the external speaker. Check whether Toybox → Boombox → Lock Sound exists on your touchscreen. If it does, the install is the same as everywhere else.

Why does my friend have the option and I do not?

Either their car has the external speaker and yours does not, or their software is newer. Update first, then check the menu again.

Does the lock sound play when I unlock?

No. Your custom LockChime.wav plays on lock only, and Tesla does not document a separate custom unlock sound.
