Can I convert an MP3 to a Tesla lock sound?

Yes. Upload any MP3, M4A, WAV, or OGG file and this free online converter will trim it to 5 seconds and export it as LockChime.wav — the one filename Tesla recognizes.

What file format does a Tesla lock sound use?

Tesla lock sounds use a WAV file named LockChime.wav saved in a Boombox folder on a USB drive. For clean playback, 44.1 kHz, 16-bit PCM, 1–5 seconds, and under 1 MB are the recommended settings — this converter applies them automatically.

Is this converter private and safe?

Yes. All processing happens entirely in your browser. Your audio is never uploaded to any server.

Can I trim or cut my audio before converting?

Yes. The built-in waveform editor lets you select the exact 5-second clip you want, then add fade in / fade out before exporting LockChime.wav.

Which Tesla models does this work with?

It works with every model that supports USB lock sounds: Model 3, Model Y, Model S, Model X, and Cybertruck.

How do I install the converted LockChime.wav?

Put the downloaded LockChime.wav on a FAT32 USB drive inside a folder named Boombox. Plug the drive into your Tesla, then go to Toybox → Boombox → Lock Sound and choose USB.
