An access code learning device of the receiver enables an access code type learning mode of operation in which the type of the first received access code identifies which of the two access code routines in executed until the next enabling of the access code learning mode. When the access code type learning mode is again entered and a rolling access routine is executed to control the opener and to learn new rolling access codes.
