How to tell which key you need

 Look at the bow (The head) if it's shaped like a house you probably have a KW1 key-way. If the key is diamond-shaped narrower at the top and bottom and wide in the middle you probably have a SC1 key-way. Some aftermarket keys use the same bow (head) shape regardless of the key-way. In this case, you can also check the key for a stamp. most of the time the keys will be stamped with Kwikset, KW1 or SC1.
