How do I use the key blank illustrations in the Ilco 60 catalog to identify a key?
A.The image of the key blank in the catalog is actual size. Laying the customer’s key on top of the image printed in the catalog will allow you to compare the two. First, look closely at the point where the keyway grooves blend into the bow (head) of the key. The ends of these millings there are referred to as “run-outs”. Second, look at the millings (grooves) in the blade of the key. Third, the silhouette (profile) of the keyway under the key blank image emulates the keyway of the lock. Place the tip of your sample key on the image as if you were intending to insert the key into the picture. That provides a method of comparing your sample key to the key blank being represented in the catalog.
