Electronic lock

An electronic lock is a type of lock that is opened by entering a code or by using a card that has a chip in it. It is very similar to the locks that you find on doors at businesses and in some homes. The code or card has to match the information stored inside the lock for the door to open. This type of lock is very secure, because it is harder to pick than the traditional locks.
