The other thing people need to understand is that thieves can grab the code from your car’s key fob door lock if you use it at a rest stop or some other place where you can be observed, and while you’re in “relieving yourself,” they are in your car “relieving it” of all your valuables, then re-locking it so you have no idea how your $hit was taken.
ALWAYS use the button on your door if you are in a place where your car can be compromised, even the parking lot at Home Depot, etc.
To prevent this from happening to garage doors, they long ago went to rolling codes. Why don’t key fob codes roll too?
That’s why I travel with a BIG DOG in My car. Walk the Dog then put it back in the car and then I go.
