1. A two way remote communication system for a vehicle, comprising:
- a key fob having an electrical power source;
a fob transceiver disposed in said key fob and electrically connected to said fob electrical power source, said fob transceiver operable to transmit and receive electrical signals;
at least one button disposed in said key fob and electrically connected to said fob transceiver and operable to initiate a transmission of a command by said fob transceiver;
a fob timer disposed in said key fob and electrically connected to said fob transceiver and said fob power source;
a vehicle having an electrical power source;
a vehicle transceiver disposed in said vehicle and electrically connected to said vehicle electrical power source, said vehicle transceiver operable to transmit and receive electrical signals;
at least one electrical component disposed in said vehicle and electrically connected to said vehicle transceiver and operable to receive signals from and transmit commands to said vehicle transceiver;
a vehicle timer disposed in said vehicle and electrically connected to said vehicle transceiver and said vehicle power source;
wherein said transceivers are operable to transmit and receive electrical signals in response to commands transmitted by said at least one button and said at least one electrical component, and wherein said timers are synchronized to simultaneously activate and deactivate said transceivers to establish periodic time intervals when said fob transceiver is open to transmission, thereby establishing idle time for said transceivers and reducing the amount of power consumed by said fob electrical power source.

Abstract
A two way remote communication system for a vehicle includes a fob portion and a vehicle portion. The fob portion includes a fob battery, a fob transceiver, at least one button and at least one display. The vehicle portion includes a vehicle battery, a vehicle transceiver, and at least one electrical component. The timers are synchronized to simultaneously activate and deactivate the transceivers to establish periodic time intervals when the fob transceiver is open to transmission, which establishes idle time for the fob transceiver and reduces the amount of power consumed by the fob battery.

15. A method for operating a two way remote communication system for a vehicle with low battery power consumption, comprising the steps of:
-
a) providing a key fob having a battery, said key fob including a fob transceiver disposed in said key fob and electrically connected to said fob battery, said fob transceiver being operable to transmit and receive electrical signals;
b) providing at least one button in said key fob, said at least one button being electrically connected to said fob transceiver and operable to initiate a transmission of a command by said fob transceiver;
c) providing a fob timer in said key fob, said fob timer being electrically connected to said fob transceiver and said fob battery;
d) providing a vehicle having a battery, said vehicle including a vehicle transceiver disposed in said vehicle and electrically connected to said vehicle battery, said vehicle transceiver being operable to transmit and receive electrical signals;
e) providing at least one electrical component in said vehicle, said at least one electrical component being electrically connected to said vehicle transceiver and operable to receive signals from and transmit commands to said vehicle transceiver;
f) providing a vehicle timer in said vehicle, said vehicle timer being electrically connected to said vehicle transceiver and said vehicle battery; and
g) synchronizing said timers to simultaneously activate and deactivate said transceivers to establish periodic time intervals when said transceivers are open to transmission, thereby establishing idle time for said transceivers and reducing the amount of power consumed by said fob battery.
-
- 16. The method according to claim 16 wherein step g) is performed by said timers simultaneously activating said transceivers for a first predetermined time interval after which said timers simultaneously deactivate said transceivers for a second predetermined time interval to complete an activation/deactivation sequence, thereby increasing the life of the fob battery.
-
17. The method according to claim 17 wherein said activation/deactivation sequence is continued for a predetermined number of sequences, after which said transceivers transmit synchronization data to ensure that said timers continue to simultaneously activate and deactivate said transceivers.
