How Long Can a Tesla Lock Sound Be?

The short answer: Tesla imposes no hard maximum duration on your custom lock sound. A LockChime.wav file can technically be 5 seconds, 30 seconds, or even longer — and Tesla will play it in full every time you lock or unlock.

But there's a practical sweet spot, and it's probably shorter than you'd expect.

The Practical Duration Limit

1 to 10 seconds is the range that works best for a lock chime.

Here's why:

●Tesla plays LockChime.wav once per lock action — from start to finish

●There's no fade-out, no loop, no early cutoff (as long as the file isn't corrupted)

●If you pick a 45-second sound clip, you'll hear the full 45 seconds every time you lock your car — in a parking lot, at 2am, outside a restaurant

A lock chime is a confirmation sound. Its job is to tell you the car locked. That takes 1–3 seconds for most people. Anything longer shifts from "chime" to "performance."

What Happens With Long Files?

Long files do work — they just create some friction:

| Duration | What happens |

|----------|-------------|

| 1–5 sec | Plays cleanly, feels like a proper chime |

| 5–15 sec | Works but may feel long in public settings |

| 15–30 sec | Noticeably long, other people will hear your whole lock routine |

| 30–60 sec | Works technically, but practically awkward |

| 60+ sec | May cause playback issues on some firmware versions |

Most sounds in our library run 2–8 seconds — long enough to be recognizable, short enough to not draw stares.

File Requirements (Not Duration-Related)

These specs matter for whether Tesla plays the file at all:

●Format: WAV only (not MP3, FLAC, or OGG)

●Sample rate: 44,100 Hz (44.1kHz)

●Bit depth: 16-bit recommended

●Filename: Must be exactly LockChime.wav (case-sensitive)

●Location: USB drive → Boombox folder → LockChime.wav

●Volume: Tesla applies some normalization — sounds mixed at 60–85 dB work best

If the file plays at the wrong speed or sounds distorted, the sample rate is usually the cause. Re-export at 44.1kHz and it'll fix itself.

Does File Size Matter?

File size is not a meaningful limit for a USB drive — even a 60-second 44.1kHz WAV is only about 5MB. USB drives that work for Tesla typically have at least 2–32GB, so size is not a concern.

The Duration Sweet Spot by Use Case

For a clean chime: 1–3 seconds. The R2-D2 beep, the Vine Boom, the mission passed jingle — these all hit their mark and stop.

For a recognizable theme: 3–8 seconds. Enough for the first phrase of a melody, a movie quote, or a sound effect with build-up.

For a novelty: 8–15 seconds. Funny the first 10 times, then you'll be editing the file.

For anything longer: Think carefully. You'll hear this every time you lock or unlock — in parking garages, at red lights, walking to and from every destination.

How to Trim Your Sound

If you have a file you love but it's too long:

1. Open Audacity (free)
2. Import your file
3. Drag to select the section you want
4. Go to Edit → Trim Audio
5. Export as WAV, 44.1kHz, 16-bit

Or skip the editing entirely — browse 900+ sounds in our library that are already the right duration and Tesla-formatted.

Frequently Asked Questions

Can I use an MP3 file renamed to .wav?

No. Tesla reads the actual file format, not just the extension. A renamed MP3 won't play. Convert it to WAV first using Audacity or an online converter.

Will Tesla cut off a long sound if I unlock before it finishes?

Yes — unlocking interrupts the lock chime. If you have a 30-second file and unlock 5 seconds in, it stops at 5 seconds.

Does the sound play on both lock and unlock?

The same LockChime.wav plays for both actions by default. There's no separate file for unlock vs lock.

Will a longer sound drain the battery?

No. The audio system uses negligible power compared to everything else running. Duration has no meaningful battery impact.
