A method for use in relation to a security system includes receiving one or more items of information that each identify things or users associated with the security system, and forming a fixed portion of a security code using the one or more items of information. The fixed portion of the security code is stored in an apparatus that is configured to transmit the security code. A method and apparatus involving the receipt of such a security code are also disclosed. A method for use in relation to a security system includes generating a fixed portion of a security code, and setting a value of the fixed portion of the security code to a value that has a relationship to a fixed portion of a previously learned security code. The relationship indicates that the fixed portion of the security code is a replacement for the fixed portion of the previously learned security code. The fixed portion of the security code is stored in an apparatus that is configured to transmit the security code. A method and apparatus involving the receipt of such a security code are also disclosed.
