Does Changing Your Tesla Lock Sound Void the Warranty?

No. Loading a custom Tesla lock sound does not void your warranty. Custom lock sounds use Tesla's built-in Boombox feature, an officially supported function, not a hardware or software modification. You're selecting a sound file through the vehicle's own menu system, the same way you'd change any other setting.

Why It Doesn't Affect Your Warranty

• It's an official Tesla feature. Tesla designed the LockChime.wav system intentionally. It's not a hack, a jailbreak, or a workaround.
• Nothing is altered. You're not flashing firmware, opening the car, or touching any hardware. You're copying a WAV file to a USB drive and selecting it in Toybox → Boombox → Lock Sound.
• It's fully reversible. Remove the USB drive, or switch the Lock Sound setting back to a built-in default, and your Tesla returns to exactly how it shipped.

This is the same answer we give in our full pros-and-cons breakdown and our Tesla horn vs. lock sound explainer: a custom lock sound is a supported setting, not a modification, so there's no warranty concern.

How to Add One Yourself

1. Download a sound from the Tesla lock sound library: every file is already named LockChime.wav
2. Copy it to a folder named Boombox on a FAT32 or exFAT USB drive
3. Plug the drive into a front USB data port and select it under Toybox → Boombox → Lock Sound

FAQ

Does changing the lock sound void Tesla's warranty?

No. Custom lock sounds use Tesla's built-in Boombox feature, an officially supported function, not a modification. You're not altering any hardware or software. You're selecting a sound file through the vehicle's own menu system. There is no warranty concern.

Is loading a custom lock sound considered a modification?

No. Tesla built the Boombox lock-sound setting into the car's own software as a supported feature. Selecting a custom sound file is the same kind of action as changing any other setting in the touchscreen menu.

Can I remove a custom lock sound if I'm worried about service or resale?

Yes. Remove the USB drive, or switch Toybox → Boombox → Lock Sound back to a built-in default, and the factory chime returns immediately. Nothing about the change is permanent.
