Tesla Horn Sounds: Free Custom Lock-Chime Downloads
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.)
Classic car & novelty horns
La Cucaracha, the General Lee Dixie horn, air horns, train horns: the honks people actually search for. Tap any card to preview, then download as a Tesla-ready LockChime.wav.
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.
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.

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?"
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.
