I doubt this is a smart key problem, the key uses a chip and its own battery. Something in the car is causing a drain, a light is staying on possibly. Trunk light, glove box light, under hood light... maybe you have a portable GPS unit plugging into the auxilary port? Just a thought. This is not a common problem that has been reported by Avalon owners as of yet.

Okay first of all do you have an eyeglass repair kit the on with a small tiny screw driver or tiny eyeglass kit that has a phillips type.look at the key and you will see a little slot to put the tiny scre driver in pop that out and the battery will be exposed.unscrew it and change battery. Wait a minute walmart when you buty the battery will replace it for free but you have to purchase the battery.Its at the jewelry area.
