For example, a lock with a keyhole can only be opened with a key; a key combination lock controls the opening and closing of the door panel by a set of passwords. In order to make the lock more convenient to use, some locks are controlled with two different devices. For example, vehicles such as automobiles and locomotives not only have a key holder, but also can be unlocked or locked by remote control. The door panels of some buildings are controlled by keys in conjunction with other electronic induction devices.

Although the locks with the above two control methods can be unlocked or locked by remote control and sensing equipment, in order to avoid failure of electronic equipment to unlock or lock, this type of lock is generally equipped with a key holder that can be opened manually. So that the door can be opened or locked by the key when the electronic control equipment fails.
