The Model S Plaid uses the same custom lock sound feature as the rest of the Model S lineup. Owners searching for “Plaid lock sound” usually want two things: confirmation that the trim works, and a clear install path. This guide covers both.
Does the Plaid support custom lock sounds?
Custom lock sounds need the external pedestrian-warning speaker and software 2023.44 or later. Tesla lists Model S from the 2021 refresh on as supported; earlier cars are not confirmed either way. We have no source for a trim difference, so a 2021-refresh-or-later Plaid is covered by the same rule as any other Model S.
To check your car, open the touchscreen → Toybox → Boombox and look for Lock Sound. If you don’t see it, update your software from Controls → Software and look again.
Find sounds for your Tesla
Every sound works on any Tesla with the external speaker.
The cabin audio system is a different thing
The lock sound plays through the external speaker, not the cabin speakers. So previewing a sound inside the car, through the cabin audio, can mislead you about how it will sound when you lock the car from outside. Check the sound from outside (see below).
USB format + file layout
One USB drive, one folder, one file:
USB Drive (FAT32 or exFAT)
└── Boombox/
└── LockChime.wav
- Format: WAV
- Sample rate: 44.1 kHz (recommended)
- Bit depth: 16-bit (recommended)
- Length: 1–5 seconds (recommended)
- Filename: exactly
LockChime.wav
If the car does not pick the file up from Boombox/, try putting LockChime.wav at the top level of the drive instead. Both locations work. A guide on USB format choices covers FAT32 vs. exFAT.
All free Tesla lock sounds on this site download as LockChime.wav, ready to drop onto a formatted drive.
Step-by-step installation
- Insert the formatted USB drive into a USB port that carries data (the glovebox port on newer cars).
- Touchscreen → Toybox → Boombox → Lock Sound, then choose USB.
- Choose your custom
LockChime.wav. - Walk out, close the door, and lock the car. The new sound plays.
If the file doesn’t appear: eject the drive, verify the format, confirm the file is at Boombox/LockChime.wav (not nested deeper), and re-insert. The full installation guide covers the same flow.
Picking a sound
Browse the Model S sounds or the full library. The external speaker is small, so very deep bass may not come through; preview bass-heavy sounds before you commit.
Checking the volume from outside
- Test outside the car at a few distances.
- If the sound is quiet, raise it with the audio converter (Loud preset, up to +6 dB of gain).
- If it distorts, lower the level with the converter’s Quiet preset or negative gain, and re-export.
We don’t have a Plaid-specific level to recommend, so adjust by ear. A general troubleshooting guide covers other playback issues.
FAQ
Does the Tesla Model S Plaid support custom lock sounds?
Tesla lists Model S from the 2021 refresh on as supported (software 2023.44 or later). We have no source for a Plaid-specific difference.
Is the Plaid lock sound louder than a base Model S?
We can’t say; we have no published speaker specs. The lock sound plays through the external speaker, not the cabin audio system.
Why does my Plaid lock sound clip even though the cabin audio is clean?
Previewing in the cabin does not tell you how the sound will play outside. If it distorts when you lock the car, lower the file’s level with the converter and test again from outside.
Can I use the same sound on a Plaid that I use on my Model 3?
Yes, there’s no Plaid-specific format or restriction. The same LockChime.wav works across every car that supports custom lock sounds.
