What is a keyway, and what’s the difference between KW1 and SC1 keyways?

The keyway is the opening in the lock where you insert a key to operate the lock. If you have more than one keyed lock on your home, you may want to use the same keyway in all of the locks. This allows a locksmith to key all of your locks to the same key, which means the same key will operate all of the locks in your home.

KW1 represents a Kwikset KW1 keyway, and SC1 represents a Schlage SC1 keyway. If you would like your new Stone Harbor locks to match an existing key, it is important to select the same keyway for your locks. One way to determine your keyway is to compare your existing key to the images below.

If you are not matching an existing key, we recommend that you order all of your new locks (keyed knobs and levers, deadbolts and handlesets) with the same keyway.
