Invisible Smart Cabinet Lock: No Visible Hardware, Just Keyless Access
Most cabinet locks are ugly — a padlock on the outside, a handle that breaks the clean look. The SK-TT21 hidden smart cabinet lock installs completely inside the cabinet, so nothing shows on the outside.
What Is an Invisible Cabinet Lock
An invisible cabinet lock mounts entirely inside the cabinet or drawer. No external padlock, no visible handle, no keyhole on the front. You unlock it with your phone (TTLock App) or an RFID card — right through the wood or metal door, no need to open anything first.
50mm Sensing Distance: Works Through Thick Doors
The SK-TT21 senses your phone or card through up to 50mm of wood or metal. That means it works on standard cabinet doors, thick wardrobes, metal lockers and sliding doors — without any cutouts, holes visible from the outside, or external hardware.
TTLock App: Remote Access and E-Keys
With the TTLock App, you can unlock with your phone, share e-keys to family or staff, and see who opened the cabinet and when. Perfect for office storage, hotel minibars, gym lockers, or home wardrobes with valuables.
