## Lock Tess Description
Record your own voice as your car's lock sound, or choose from over 70 hand-picked sounds. 10 library sounds are free to try. Premium unlocks the full library, voice recording, and unlimited imports, plus iCloud sync across your devices. Lifetime unlock, no subscription, ever.

Lock Tess lets you customise your car's lock sound in seconds - all from your iPhone, iPad, or Mac.

Simply pick a sound from our built-in library, record your own, or import a file, then connect your USB drive to your iPhone, iPad, or Mac and tap Use. Lock Tess handles all the technical stuff automatically, creating the correctly named file your car needs. Plug the USB back into your glovebox USB port, enable USB as the sound in Boombox settings, and enjoy your new lock sound every time you walk away from your car.

--- SOUND LIBRARY ---
Over 70 hand-picked sounds ranging from funny to satisfying. Air horns, retro bleeps, dramatic stings, space missions, animal sounds, and more.

--- RECORD YOUR OWN ---
Say it yourself. Record straight into Lock Tess, watch the level as you go, and play it back before you keep it. Trim to the perfect moment and it's ready to use - no second app, no file converting, just you and your creativity.

--- IMPORT ANY SOUND ---
Found the perfect sound elsewhere? Import it! Lock Tess accepts MP3, WAV, M4A, AIFF, and FLAC files, automatically compressing, converting, and renaming to the exact format your car needs. Plus, for longer sounds, drag along the waveform to pick exactly which part you want to use.

--- ORGANISE YOUR SOUNDS ---
Store all your lock sounds in one place. Search, filter, rename, and categorise your sounds, mark your favourites for quick access, and share your sounds with friends via AirDrop, Messages, and more.

--- YOUR SOUNDS, EVERYWHERE ---
Lock Tess works beautifully on iPhone, iPad, and Mac. Unlock once and use everywhere. With iCloud Sync, your imported sounds automatically back up to iCloud and stay in sync across all your devices. Delete on one device and it disappears everywhere. Import on your iPhone and it appears on your Mac. Your sounds, always where you need them.

--- NO SUBSCRIPTION EVER ---
Lock Tess is free to try with 10 included sounds from the library. Unlock the full experience with a single payment. No monthly fees, no adverts, no subscriptions, no surprises.

--- HOW IT WORKS ---
Pick a sound from the library, record your own, or import a file
Connect your car's USB drive to your device (USB C or Lightning adapter may be required)
Tap Use - Lock Tess creates the LockChime.wav automatically
Save to the root of the USB, then plug back into the glovebox USB port
Enable in Toybox > Boombox > Lock Sound > USB
Enjoy your new lock sound!

--- COMPATIBLE CARS ---
Compatible with most Tesla cars equipped with the Boombox feature and Pedestrian Warning System PWS speaker (from September 2020 onwards) - if your car has Boombox in the Toybox menu, you should be good to go. Before you purchase there are 10 free sounds to test the full process.
