There are several types of keys, but they all fall into one of two types: low-tech keys for mechanical locks and high-tech key cards for electronic locks. If the key looks like one you might find on your own key ring at home, it's for a low-tech lock. If the key looks like a brightly colored flat plate or card, it's for a high-tech electronic lock. Electronically locked doors are often color coded so that you can figure out which color key card goes with which door.
A key will open a particular lock.
