Keyless access and engine control system

摘要

A keyless marine access and engine control system. The system is caused to change from a dormant state to an enabled state when a sequence of actuation signals entered through a keypad matches data representing either one of two access sequences stored in the system's memory. When the system is in its enabled state, the system responds only to signals representing a keypad actuation exceeding a first predetermined time interval. These signals are used to crank, choke, and stop a marine vehicle engine. The secondary access sequence can be changed by a person who knows either the primary access sequence or the secondary access sequence, while the primary access sequence can be changed only by a person having knowledge of the present primary access sequence. In order to reprogram either access sequence, a programming button must be actuated for a predetermined time interval exceeding the first time interval. The system can be used with either a single or dual engine installation.
