Novelty car horns, air horns, train horns, and stadium goal horns — every clip below installs as your Tesla's LockChime.wav and plays when you lock the car. (Heads up: the honk you press on the wheel is federally regulated and can't be swapped — these are lock sounds.)

Sports goal horns
The Vikings Gjallarhorn, NHL goal horns, the NBA on NBC fanfare — arena energy for every time you walk away from the car.
The honest answer
Can you change the actual Tesla horn?
Short version: no. The horn you press on the steering wheel is a federally regulated safety device, so Tesla doesn't let you replace it. The horn sounds here install as your lock sound instead — the clip that plays when you lock or walk away from the car. That part is fully customizable.

Step 2
Drop it into a Boombox folder

Step 3
Plug into the front USB-C port
Insert the drive into your Tesla's front USB-C data port (the rear ports are power-only). Wait two to three seconds so the car indexes the drive.
Step 4

FAQ
Tesla horn sound questions
Can I change the actual horn my Tesla honks with?
No. A car's horn is federally regulated for safety, so Tesla doesn't let you swap the honk you press on the wheel. What you can change is the lock sound — the clip that plays when you lock the car. The horn sounds on this page install as that LockChime.wav lock sound, not as the road horn. Full detail: see "Can You Change Tesla Horn Sound?"
Are these Tesla horn sounds free to download?
Yes. Every horn sound here is free — no account, no email gate, no paywall. Each file downloads as LockChime.wav, ready to drop onto a USB drive.
What format does the file need to be?
A single file named exactly LockChime.wav inside a Boombox folder on a FAT32 or exFAT USB drive. The clips here are already 44.1kHz, 16-bit PCM WAV — the recommended format for clean playback through Tesla's external speaker.
Will a horn lock sound work on my model?
If your Tesla has the external pedestrian-warning speaker, yes. That covers Model 3 (built September 2019 or later), all Model Y, the 2021-refresh-or-later Model S and Model X, and every Cybertruck. Custom lock sounds have been available since Tesla's 2023 Holiday Update (software 2023.44).
How do I make the horn quieter or louder?
Open Vehicle → Locks on the touchscreen and drag the Boombox lock-sound volume slider. It's independent from media volume, so a loud air horn won't blast your music levels.
