Long story short.
Dad's dead, Mom's driving Dads car, battery dies, now the door combination doesn't work to the code Dad had set it to, now Mom's locked both sets of keys in the car. How does she figure out what the default code is?
Mom's an hour plus away from me :x I've told her to call a locksmith or a tow truck if she has to get in the car tonight. If not, then I told her to call the dealer in the morning.
