How to Set a Tesla Lock Sound with LockChime.wav
Download a WAV lock chime, put it on a USB drive and select it in your Tesla. Use the checklist below if your custom sound does not appear or play.
Custom lock sounds require a supported vehicle with the external Pedestrian Warning System speaker and the Lock Sound option in Toybox. Menu labels and availability can vary by vehicle and software; check your vehicle’s manual.
- Choose a sound
Use the player on a sound card to preview the clip. Download the WAV file using the download button. - Check the filename
The downloaded file should be named LockChime.wav. If your browser adds a number, rename it. Show file extensions so the name does not accidentally become LockChime.wav.wav. - Copy it to USB
Put LockChime.wav at the top level of a USB drive your vehicle can read. Do not leave it inside the Downloads folder on your computer. - Connect the drive
Use a USB port that supports data. Some center-console ports provide charging only; check the glovebox port and the manual for your model. - Select the sound
Open Toybox > Boombox > Lock Sound and choose the USB option. Test by locking the vehicle from outside.
Back up recordings and other files before formatting or replacing anything on the USB drive. If the car already reads the drive, check the filename and location before considering a format.
Where does LockChime.wav go?
Place the file in the root of the USB drive, alongside any existing folders. This is the lock sound file, separate from the Boombox folder used for other custom Boombox sounds.

LockChime.wav not working?
The car cannot find the file
Check the exact filename, including its extension, and confirm it is at the top level of the connected USB drive. Keep one file named LockChime.wav.
The file is not really a WAV
Renaming an MP3 file to .wav does not convert its audio. Download the WAV version and confirm that it plays on your computer or phone.
The USB drive is not recognized
Check the data-capable port and the USB formats supported by your vehicle’s manual. Reconnect the drive after copying the file. Preserve your recordings before making changes to the drive.
The Lock Sound option is missing
Check that the vehicle has the required external speaker and supports custom lock sounds. A software version alone does not guarantee the necessary hardware.
The sound is too quiet or different
Preview another clip and compare it in the vehicle. A phone speaker and the external vehicle speaker can sound different.
Downloading on a phone
Save the download in your phone’s file manager. With a compatible data adapter and USB drive, copy the WAV file to the drive’s top level and check its name. If your phone cannot write to the drive, transfer the file with a computer.
