A remote control (RC) device and base station of a security system communicate automatic passive remote control commands at a lower power level than the level used to transmit other information. Lowering the power level of the passive remote control transmissions from the RC device decreases energy consumption and improves battery life. Additionally, the range of the automatic commands is shortened, potentially avoiding some unwanted door lock activations, security system arming and disarming events, and similar occurrences. At the same time, the range of the user-entered commands does not suffer. In embodiments where the RC device sends passive remote control commands in response to periodic interrogatory transmissions from the base station, the power level of the interrogatory transmissions is lower than the power level of other transmissions. Thus, frequency of unwanted door lock activations and arming/disarming events is decreased, while the range of other transmissions from the base station is unchanged.
