Abstract

A keyless system for controlling e.g. the doors of a car comprises an input station containing a keyboard, a signal processor, a signal amplifier and an electromechanical grouping which converts the electrical output from the amplifier to mechanical movement in control of a lock. The system is activated by touch control of the keyboard and with the power section of the system energized, the lock is controlled in response to a proper sequence of digital input signals. The keyboard may have five selectors, resulting in approximately three thousand possible combinations for a base code. The signal processor responds to correct combinations of digital inputs with a drive signal. The signal processor is also programmable with temporary convenience codes which are loaded into the logic portion of the system with access preconditioned on entry of the base code. <IMAGE>
