My mom is showing signs of early dementia and at times she knows it. Still, she wants to be independent but it's clear she's in over her head. At the early warning signs I hid her keys to prevent her from driving but for the past month she asks me at least 3 times a day for her fob. I explain the situation to her as calm as possible but sometimes I grow tired. I've been thinking I could giver her her keys but remove the batteries.
She's paying for a 2016 Nissan Altima that can only operate with a fob. I remember before the dementia her fob died once and would only allow her to unlock the doors. Fixing the fob is hard to do so I wouldn't have to worry about her doing anything irrational and besides I have friends watch her during the day until her disability begins. They don't mind taking her places either.
So anyway, should I give her a dead key? Does that sound like a good plan or is that mean?
