The compact design of the TCL K2 smart door lock cuts down on the number of movable components it contains. Equipped with a conveniently large handle which houses the biometric fingerprint unlocking mechanism, this ergonomically well-thought-out design makes the opening and closing of doors quick and easy. The die-cast lock is made of high-quality aluminium as used in the aerospace industry. The operating panel employs IML technology which mimics the texture of metal.
