This a replacement key for SEEBURG JUKE BOXES that are using a YALE LOCK. You need to be sure you are ordering the right key because Yale also used this key code for other companies products and they are different. A quick way to know if this will even fit in your lock is to compare the line drawing picture of the keyway in the blank example pictured, to your lock entrance key shape. The view of the keyway is as if you were actually inserting the key. The two codes that Yale used for this have OPPOSITE keyways so it should be easier to tell which is which hopefully.
