The manual says that the Comfort Access key cannot be charged by inserting in the slot. Instead, there's a battery that has to be replaced periodically. Such is the case with the key for my Lexus IS250, a 2006 model.
My key stays in my pocket....
Usually the slot is only there so you can insert it to start the car if the fob battery dies. It doesn't need to be in there any other time.
