Tesla Model Y Custom Lock Sounds — 2026 USB Setup in 2 Minutes
Looking for how to add custom lock sounds to your Tesla Model Y in 2026? Whether you have the new Juniper refresh or an earlier model year, the process is the same: format a USB drive, add LockChime.wav, plug it in, and select your sound. Here's the complete walkthrough.
2026 Model Y (Juniper Refresh) — What Changed?
Tesla's redesigned 2026 Model Y (Juniper) keeps the same Boombox feature and LockChime.wav folder structure. The only differences that matter for lock sounds:
Boombox/LockChime.wav on a FAT32 or exFAT driveEarlier Model Ys (2020–2025) use the same steps but with a USB-A port in the center console. Both paths are covered below.

Compatibility
Step-by-Step USB Installation
1. Prepare Your USB Drive
Format your USB drive to FAT32 or exFAT. For 2026 Juniper Model Y, use a USB-C drive (or USB-A with a USB-C adapter). For 2020–2025 Model Y, a standard USB-A drive works. We recommend 32GB or smaller for best compatibility.
2. Create the Folder Structure
USB Drive/
└── Boombox/
└── LockChime.wav
3. Add Your Sound File
Download a sound from our Tesla lock sound library — it's already named LockChime.wav. Place it in the Boombox folder.
4. Install in Your Model Y
- Insert USB into the front USB port — USB-C port (glovebox) on the 2026 Juniper Model Y, or USB-A port (center console) on 2020–2025 models
- Tap Controls on the touchscreen
- Navigate to Safety & Security
- Select Sentry Mode
- Look for Custom Sound option

FAQ
Do all Tesla Model Y years support custom lock sounds?
Yes. Every Model Y produced from 2020 onward supports custom lock sounds through the Boombox feature. All production units include the external pedestrian warning speakers needed for the feature. You need software version 2020.48 or later, which all current Model Y vehicles exceed.
Which USB port on the Model Y is best for custom sounds?
On the 2026 Juniper Model Y, use the front glovebox USB-C port — it's the most reliable for custom sound detection. On 2020–2025 Model Y, use the front USB-A port in the center console. Avoid the rear USB ports as they don't always trigger the sound change. Make sure the drive is formatted as FAT32 or exFAT.
Why isn't my custom sound playing on my Model Y after setup?
The most common causes: Sentry Mode isn't enabled (it must be on for the feature to work), the USB drive isn't formatted as FAT32 or exFAT, the file isn't named exactly LockChime.wav (case-sensitive), or the file isn't inside a folder named Boombox at the root of the drive. Check these four things in order.
How loud should I set my Model Y lock sound?
Normalize your audio to -6dB peak — the Model Y's front speaker has good mid-range output but isn't as powerful as the Cybertruck. Avoid bass-heavy sounds as they won't reproduce well. Test from 20 feet away after installation; if you can't hear it clearly, boost to -3dB using our audio converter.
Can I use a different sound for lock vs. unlock on Model Y?
This depends on your firmware version. With 2026.8 or later, you can set a separate UnlockChime.wav file for unlocking. On older firmware, the same LockChime.wav plays for both events. Check your software version in Controls → Software.
