Dead battery

WAYS YOU’RE DRAINING CAR BATTERY THAT YOU MIGHT NOT REALIZE
3. Car Key
Once upon a time, car keys were metal things you put into a slot and turned to unlock the doors. Some cars still have traditional keys, but many have proximity keys. These let you walk up to the car to automatically unlock the doors. It’s a handy feature when your arms are full and your key is stuffed in your pocket, but one that can also cause battery issues.A receiver in your car is constantly searching for your proximity key’s frequency. Whenever it finds that frequency, it checks to see if it’s an exact match to your car. Any proximity key wakes things up. If you’re parked next to the entrance of a parking structure where everyone is walking by with proximity keys in their pockets and you happen to leave your car for an extended period, then your car battery can drain. It won’t be an issue for every car, but particularly in hybrids, it might be your problem.

The FOB communicates to the car:
1) When you push a button on the FOB (distance from car does not matter).
2) When you are standing within 3' of the door (P or D) and then press the Door Pad to open the door. The car talks to the FOB and the FOB answers back.
3) When you are within 3' of the trunk/hatch and press the open button under the trunk lip to open the trunk/hatch. The car talks to the FOB and the FOB answers back.
4) When you are sitting in the car ready to start the engine and press "Start". The car talks to the FOB and the FOB answers back.
5) When you leave the FOB in the car after shutting the engine off and you have the triple beep warning set to sound, the car talks to the FOB and the FOB answers back.
6) When the car is set to "Autolock", the car will lock 5 seconds after the last door/hatch/trunk is closed. The FOB distance from the car does not matter UNLESS the FOB is in the car and is detected by the car.
Otherwise, your FOB does not communicate with the car and is listening for the car and using a fantastically minuscule amount of power to "look" for a signal from the car.
The car does NOT constantly look for the FOB.
