Keyless entry systems generate a signal to actuate a security system on a vehicle (22) when keyless entry system is outside of a range of the vehicle. The signal is transmitted to the vehicle once the keyless entry system is within range. In a first embodiment, the signal continues to be sent periodically over a period of time such that the operator can move within range of the vehicle. In a second embodiment, the request signal is stored at the keyless entry system until the keyless entry system receives a signal from the vehicle, which then indicates the keyless entry system is within range of the vehicle. At that time, the signal is sent to the vehicle. This invention facilitates the use of keyless entry systems for a person carrying a number of packages, such that the operator need not actuate the keyless entry system when approaching the vehicle. Further, the system would allow the operator to keep the keyless entry system concealed when approaching the vehicle so as not to provide an indication of which vehicle the operator is approaching.
