Hid extra "key" in Altoids tin in the First Aid Kit

That makes sense.
I might offer a small bit of advice. take the battery out of it, maybe store it in the glove box.
this will accomplish two things.
1. it will be sure that the fob doesn't activate at any point killing the battery or allowing the car to be started,
2. prevent someone from starting the car if they found it.
also this might be better for your wallet:
pretty sure you can have it cut to work on your car.

Look at it this way, you would know pretty quickly if you forgot/lost your wallet because the RX won't open or start Adding to what mjeds said, it's pretty risky leaving the key fob inside, especially after announcing where you keep it. And how do you lock it? Wait, don't answer that question.
The electronically shielded "B" key fob allows the vehicle to be locked.
Would "B's" electronic "registration" allow it to be locked in the vehicle using "A" key fob to lock the vehicle?

"Take the battery out."
Yes. Thank you. I wanted to hide the battery so "B" fob, if found, still would not work.
But wife does not want me to tear open its leather case.

There are lots of places you could hide a FOB in the car. In my SC430 I hid it in the trunk, out of site, under the jack. If a thief breaks into your car I doubt he/she would rummage under the rear deck looking for a key.

Yes, the procedure for a dead battery in the remote key fob to start the Lexus is to hold it touching the start button for at least two seconds and then foot on the brake and press START with the dead battery key fob.
I'm pretty sure that a FOB either without a battery or with a dead FOB battery can still be used to start the car. You just touch the START button with the FOB rather than your finger. It's designed that way as a fail safe.

Is it inducing a current in the FOB circuitry and detecting signal emission from the FOB?

It uses a passive RFID chip that is embedded into the smart key.
There are 2 coils involved in this process, one is wrapped around the start button of the vehicle and the other is in the key itself. Former activates the latter.
This is the same old tech used in transponders of mechanical keys.
Smart key operates differently by actually transmitting a signal, hence why it needs a battery to work and does not need to be in the same proximity as an RFID chip.
