Abstract
A security system uses an ordinary switch, which may be an existing switch such as a parking light switch, to enter digits of a security code, with the beginning of a digit being indicated by turning on the ignition switch and the end of a digit being signified by turning off the ignition switch. Entry of the security code can be used to perform an emergency system disarm when the remote control transmitter is lost, to change the security code when the transmitter is in the possession of the owner, and to teach a new transmitter.
