Tesla Sound Effects: Every Built-in Sound and How to Change Them
Tesla makes a lot of sounds. Some are locked in firmware. Some you can swap out entirely. Here's the full map of what plays when, and exactly which ones you can replace.

External Sound Effects (What People Outside Hear)
1. Lock Chime
The signature two-tone "beep" that plays every time you lock the car. This is the one you can fully replace via the Boombox feature — and the main thing this site is about.
What it sounds like stock: A short, high-pitched confirmation chirp. Quiet, clean, unmemorable.
Can you change it? Yes. Place a file named LockChime.wav in the Boombox folder on a USB drive, plug it into a front data port, and select it in Toybox → Boombox → Lock Sound → USB.
2. Pedestrian Warning Sound (AVAS)
At low speeds (under ~18 mph), Tesla plays a generated "electric hum" through the external speaker so pedestrians can hear you approaching. This is mandated by law (FMVSS 141 in the US, similar rules in the EU), so you cannot disable or replace it.
What it sounds like: A rising synthetic tone that scales with speed — like a quiet sci-fi engine. Varies slightly by model and firmware version.
Can you change it? No. The pedestrian warning tone is a regulatory requirement. It stays.
3. Horn
Pressing the steering wheel center pad plays a standard horn. Using the Boombox menu lets you add supplemental sounds — but the safety horn itself is never replaced.
Can you change the Boombox horn sound? On Model S, Model X, and Cybertruck: yes. Navigate to Toybox → Boombox → Fart Mode (or horn sounds) and select a custom or pre-loaded option. On Model 3 and Model Y, the in-car horn playback is limited — the exterior speaker option is not available for horn replacement on those models.

Internal Sound Effects (What You Hear Inside)
4. Turn Signal Click
A mechanical-sounding click plays inside the cabin whenever the turn signal is active. It simulates the sound of a traditional clicking relay — old-school tactile feedback baked into a digital-first car.
Can you change it? No. The interior turn signal sound is fixed.
5. Sentry Mode Alert Tones
When Sentry Mode detects motion, it plays a tone and activates the dashcam. The exact sound varies by alert level:
Can you change it? No. Sentry Mode tones are system sounds.
6. Reverse Warning (interior)
A soft pinging sound plays when you're backing up and the ultrasonic sensors detect something close. The frequency increases as you get closer to an obstacle.
Can you change it? No.
7. Navigation Voice
Directions are delivered through the cabin speakers by a built-in text-to-speech voice. You can adjust the volume but not swap the voice.
8. Notification Chimes
Calendar reminders, service alerts, and software update notices all get a short system chime. Standard across all models.
Can you change them? No.

What You Can Actually Customize
Only one external sound is fully replaceable: the lock chime. Everything else is either:
The Boombox Lock Sound: How It Works
The Boombox feature — available on any Tesla running software 2023.44 or later with an external pedestrian-warning speaker — reads a file named exactly LockChime.wav from a USB drive. When you lock the car, that file plays through the external speaker instead of the factory chirp.
The setup in full:
- Format a USB drive as FAT32 or exFAT (under 32 GB)
- Create a folder called
Boomboxat the root of the drive - Place your
LockChime.wavinside it — full path:Boombox/LockChime.wav - Plug into a front USB data port (not the rear charging ports)
- Go to Toybox → Boombox → Lock Sound → USB
- Lock the car to hear it
Every sound in our library downloads as a ready-named LockChime.wav at 44.1 kHz / 16-bit, pre-formatted for Tesla. No conversion needed — just download and drop in.

| Model Y | All model years |
| Model 3 | Built September 2019 or later |

If you don't see the Lock Sound option in Boombox, update your software from Controls → Software.
