A two-in-one wireless control kit is adapted to plug in a PCMCIA slot on a portable apparatus for storing and moving along with the portable apparatus and use at any time, and includes a transmitter and a receiver removably associated with each other to form one unit. The transmitter is provided at an upper side with related keys and at a lower side with at least a battery compartment for accommodating required batteries and a locating recess for receiving the receiver therein. The receiver includes a front connecting end for connecting to a related connecting port on the portable apparatus, and locating structures located at predetermined positions to removably engage the receiver with the locating recess below the transmitter, such that the associated transmitter and receiver can be plugged in the PCMCIA slot without projecting any part from the slot.
