Abstract
A unique system is provided for storing home security function signals such as garage door opener signals on a vehicle key/fob combination. The key/fob combination learns its coded signal from a control on the vehicle. In this way, the key/fob combination need not be provided with an expensive scanning receiver. The vehicle control preferably communicates to the key/fob combination through the LF receiver/transmitter that is already typically part of the vehicle immobilizer system. In further features, a coded key pad may be provided such that the system may be moved into a secure mode when the key/fob combination or vehicle is in the control of a valet. Further, the key/fob combination may be provided with a switch such that it can be moved into home or auto mode such that the number of switches on the key/fob combination may be reduced.
