Sounds like she needs a bigger purse.Kinda hard for my wife to keep the mirror in her purse.
We weighed my mom's purse once and it was 25lbs. She started carrying just a wallet after that.
It's weird to me that 1/2 of us have to use the key and 1/2 don't. Someone here said that both wires are there, one is acc and one is always hot.
