The file must be named exactly LockChime.wav. It is the only name Tesla recognizes.
Model 3/Y: front console port (USB-C on newer builds, USB-A on older). S/X and CT: center console.
Walk away or hit the key fob. Your sound plays through the external speaker.

Port layout varies by model year
If the first port doesn't show USB in Boombox, try the other front or glovebox data port before changing files.

Confidence levels are conservative and source-linked.
Hardware requirement: external speaker
Lock sounds play through the Pedestrian Warning Speaker (PWS). Model Y and Cybertruck include it on every unit. Model 3 needs a September 2019 or later build. Model S and Model X need the 2021 refresh. Not sure? Open Toybox → Boombox. If it appears, you have the speaker. Full eligibility FAQ.
| Model | Years | Confidence | Install path | Notes | Sources |
|---|---|---|---|---|---|
| Model Y | 2025+ (Juniper) | Confirmed | Standard LockChime USB path. Test both front data ports if USB does not show first try. | Owner docs and Model Y install walkthrough agree on the same Boombox flow. | S3, S7 |
| Model Y | 2020-2024 | Confirmed | Standard LockChime USB path. | Boombox path documented; aligns with active install guides. | S2, S7 |
| Model 3 | 2024+ (Highland) | Confirmed | Standard LockChime USB path. Prefer glovebox/front data port. | Owner docs support Boombox on current Model 3 platform. | S1, S7 |
| Model 3 | 2018-2023 | Likely | Standard LockChime USB path; expect port-behavior variance by build date. | Older docs and field reports are mostly positive but not uniform across trims/markets. | S8, S7 |
| Model S | 2021+ (refresh) | Confirmed | Standard LockChime USB path. | Current docs and model-specific guidance align on Boombox support. | S4, S7 |
| Model X | 2021+ (refresh) | Confirmed | Standard LockChime USB path. | Boombox documented for current Model X generation; matches install guides. | S5, S7 |
| Model S / Model X | 2016-2020 | Likely | Standard LockChime USB path if Boombox and external speaker hardware are present. | Legacy docs note hardware caveats; results vary by configuration and region. | S4, S5 |
| Cybertruck | 2024+ | Confirmed | Standard LockChime USB path. | Owner docs include the same Boombox customization path. | S6, S7 |
| Model S / Model X | 2012-2015 | Unknown | Check Boombox in-car before USB prep. | Inconsistent evidence for earliest builds; confirm Boombox is visible first. | S4 |
| Roadster (original) | 2008-2012 | Unsupported | No LockChime USB path. | Roadster docs do not include the Boombox/Toybox lock sound workflow. | S9 |
Unknown is not a hard no. If your row is unknown, run the same USB checklist first, then use the troubleshooting sequence before you assume your car is unsupported.

Format a USB drive as FAT32 or exFAT, create a folder named Boombox, and place your WAV file inside named exactly LockChime.wav. Plug the USB into a front data port on your Tesla, then go to Toybox → Boombox → Lock Sound → USB.
For Model Y 2026, use a USB-C drive or USB-A-to-C adapter, place LockChime.wav at Boombox/LockChime.wav on a FAT32 or exFAT drive, insert it into a front data USB port such as the glovebox port, then go to Toybox → Boombox → Lock Sound → USB.
Model Y, Model 3, Model S, Model X, and Cybertruck are the primary supported lineup. Legacy years vary by hardware and firmware. Use the model/year install-confidence matrix on this page for confirmed, likely, unknown, and unsupported status before you prep your USB drive.
Unknown means we could not verify a model/year path with current primary documentation or consistent field reports. It does not mean 'impossible.' Start with the standard Boombox/LockChime.wav checklist, then use the troubleshooting flow if USB does not appear.
Tesla lock sounds must be WAV format (44.1kHz, 16-bit PCM), named exactly LockChime.wav, inside a Boombox folder on a FAT32 or exFAT USB drive. Keep files 1–5 seconds. All 1,053+ sounds on TeslaLockSound are pre-converted to this exact format.
In almost every case, one of four things is wrong: the USB format (must be FAT32 or exFAT), the folder path (must be Boombox/LockChime.wav), the filename capitalization (must be exactly LockChime.wav), or the USB port (must be a data port, not power-only).
Tesla usually falls back to Light Cycle when one setting or file detail is off. Confirm Boombox is set to USB, confirm the exact path is Boombox/LockChime.wav, confirm the filename is exactly LockChime.wav, then reinsert the USB drive and lock once to retest. For the Tron/Light Cycle fallback explainer, see /blog/tesla-tron-mode-sounds-lock-turn-signal.
