Yesterday a lady in my guild warned us about using your remote to lock your car. Criminals have a device that can get your signal and unlock your car when you walk away.
It happened to her and her son (in a different state). She caught them when she came out to her car from the Dr's office before they stold anything.
She said if you lock it from the inside door, they can't get in.
Just thought I'd pass this info on.
