So many situations can happen that will let you out of your keys. You can lose them somewhere around the house, forget where you put them, maybe your children took them to play with them, and the worst scenario is someone stealing them. Sometimes, you may get lucky and remember where you put them, or find them in unexpected places, but in the last scenario, you will not be able to use your car unless you have a spare key or you ask the help of a car key locksmith to enter your car.
