The Lexus RX330 Door Lock provides reliable security by preventing each door from opening and keeping unauthorized hands out of the cabin, as well as preventing doors from opening when the vehicle is in motion. Early RX330 editions had a simple key cylinder connected via rods to the latch so turning the key or pushing the interior knob disabled the exterior handle. As the lineup progressed, Lexus incorporated the techniques of power locking, in which the Door Lock has an electric actuator at each latch controlled by a master switch, eliminating the need for reaching for individual knobs. Subsequent RX330 years saw the acceptance of remote keyless entry, the key fob transmitting a coded radio signal to a receiver that directs every Door Lock motor to lock or unlock, with horn or light flashes indicating the action. Many vehicles in this family are now fitted with automatic locking to lock all the Door Lock units once Drive is selected or once a certain speed is reached and to release them in Park, providing Lexus drivers with seamless protection. Throughout these updates, there has been a core consistency in the layout of the Door Lock which utilizes a latch clasp and striker, applied on the RX330 within the Lexus range.
