Tesla Model Y Juniper Custom Lock Sound Guide (2024

Model Y compatibility by year

Custom lock sounds have worked on every Model Y since the Boombox feature launched. What changed with Juniper is the USB connector and which port the car treats as a data port versus a charge-only port.

Model Year	Refresh	Primary USB port	Boombox path	Supports custom lock sound
2024–2026	Juniper	USB-C (front console) or glovebox data port	Toybox → Boombox → Lock Sound → USB	Yes
2021–2023	Standard	USB-A (front center console)	Toybox → Boombox → Lock Sound → USB	Yes
2020	Launch	USB-A (front center console)	Toybox → Boombox → Lock Sound → USB	Yes

If your front console port only charges and never shows a drive in Boombox, use the glovebox data port instead.

Step-by-step install

Every sound you download from our library is already named LockChime.wavand formatted to Tesla's 44.1 kHz / 16-bit WAV spec. You just need to put it in the right folder.

1

Format your USB drive

Format as FAT32 (recommended) or exFAT. Keep the drive at 32 GB or smaller — larger drives sometimes cause detection issues. APFS and NTFS are not supported. On Mac use Disk Utility; on Windows use right-click → Format.

2

Create the folder structure

At the root of the USB drive, create a folder named Boombox. Place your LockChime.wav inside it. The final path should be:

USB_DRIVE/
└── Boombox/
    └── LockChime.wav

3

Plug into the correct port

On Juniper (2024+), start with a front USB-C data drive or use a USB-A to USB-C adapter. If the car does not detect the drive after 30 seconds, move it to the glovebox data port — this is the most reliable fallback on Juniper builds. On pre-Juniper Model Y, the front USB-A ports in the center console work directly.

4

Select the sound via Boombox

On the touchscreen:

Tap Toybox
Tap Boombox
Tap Lock Sound
Select USB

Note: Lock Confirmation Soundunder Controls → Locks is Tesla's stock chirp setting — that is not the same thing. The Boombox menu is what reads your custom file.

5

Verify

Lock the car from the app or walk away with walk-away lock enabled. You should hear your sound from the external speaker. If you only hear the default chime, check the troubleshooting section below.

For the full model-agnostic walkthrough with photos, see the Tesla lock sound installation guide.
