I don't think there is any location in my house that meets this.

Re: After 22 months, battery is toast
In comparison, my Sienna is going to be 5 yrs old next month, and both (conventional) fobs are still on the original battery. I went by the dealer to get the battery replaced since I figured these fobs are expensive and I didn't want to be responsible for wrecking it trying to pop it open. They didn't have any on hand. They have never seen a battery in one of these fobs go dead before...

Yes, thus the power saving mode
The vehicle battery may drain if the vehicle is not used for a long period of time.
To prevent battery drain, disconnect the battery negative (−) terminal or disable the smart key system. (For details about disable the smart key system, see “DISABLING THE SMART KEY SYSTEM” in this Section.)
To reactivate the smart key system, perform any of the following:
(a) Press the lock button on the front outside door handle or trunk open button while carrying the electronic key.
(b) Perform a wireless remote control operation.
(c) Insert and turn the mechanical key in the keyhole of the driver’s door.
BATTERY POWER SAVING
Both the vehicle and key transmitters are always sending signals to each other. To prevent battery drain, the smart key system is automatically deactivated in the following conditions:
Both the vehicle and key transmitters are always sending signals to each other. To prevent battery drain, the smart key system is automatically deactivated in the following conditions:
- If the electronic key is left outside of the vehicle and within the effective range of the entry function actuation area for more than 10 minutes.
- If the door lock or unlock operation is not performed more than 2 weeks.
The key and the vehicle are communicating even while the vehicle is not being driven. Do not leave the key near the vehicle (within 2 m [7 ft.]).

HINT: If your bedroom table is on a common wall with the garage that the car is in, I suggest you put your keys ACROSS the bedroom. If the fob is in range to the car, then it will not "sleep". It will sit there and respond to the cars interrogations all night long. My brother discharged his in only four months!

I believe the MFD has a warning message to warn you that the key fob battery is low. If you didn't get that you either didn't notice it or the battery just failed.
