ABSTRACT:
A key assembly is provided which includes a support and retainer for a coded electrical circuit which is responsive to short wave radiation for use in security systems which employ the key to open a lock or close a switch for controlling a machine or gaining access to a locked container or room. In one form, a plastic housing surrounds the head of the key and supports or contains an electrical circuit means which is operable for generating a coded short wave signal or affecting an energy field in a coded manner to enable the operation of a machine or motor vehicle. Two or more plastic components are shaped and constructed to not only hold and retain various electrical circuits but also to allow their simple and rapid assembly against and around the head of a key. Retention means for the plastic assembly in the form of ultrasonic welding, fusion bonding, solvent bonding or other means is provided for rapid and easy assembly of the key and electronic circuit. In one form, such assembly is easily disassembleable while in another form, an attempt to disassemble such assembly results in destruction of the electronic circuit so that it may not be easily duplicated or copied.
