Leaving Key fob in vehicle
 
I leave my fob in my cup holder in the jeep overnight as I have a attached garage. Does anyone know if this will accelerate key or Jeep battery drain?

I,m guessing most with home garages would leave their keys in the ignition. With the new key fob, not sure if the jeep continuos communicate with the key which would use battery.
When I go in for service, will ask the Tech and post an update.

I had a neighbor who left the key fob in the cup holder all the time, and one night they forget to close the garage door. Next morning the jeep was GONE!

Before your neighbors car was stolen! Did they have any problems with premature battery drain leaving the key fob in the car all the time?

I would believe the Fob battery will not drain any faster left sitting in the GC, than if stored inside the house.

The Fob is "active" in that it is "constantly" tranmitting a signal, albeit not a very strong signal (the range is approximatly 3-5 feet in active/passive mode - ie when not pushing a button).

But the battery life in these new active/passive Fobs is less than old style Fobs that only transmit when you are pressing a button.

I still recommend changing the Fob batteries annually, and keeping a spare battery at home and another in the glovebox. You can purchase a 5-pack of CR2032 batteries for under $15. Pretty cheap maintenance and insurance.

And I agree that leaving the keys in your GC, even in your garage, is not a good idea. Just ask your insurance agent for the percentage of vehicles that are stolen, that have the keys in them. Many owners with garages leave the keys in the vehicle or hanging on a hook next to the door into the house, and many thieves are well aware of that...

As for leaving keys in the car, battery operate fob or standard. Everyone situation and routine is different along with the risk which could be a topic for another theard. Thanks to all that commented and keep your Jeep safe as they are good looking vehicle :).

As I understand it, the keyfob only uses battery power when you press a button. If the fob is just sitting in the car, it will do nothing until the truck interrogates it, usually after you put your hand inside the door handle ... and the keyfob reply is an RFID chip that is powered by the interrogating signal. So keeping the fob in the truck should be fine until some unauthorized person decides to take your vehicle for a spin.
