This is an older C series key code that is a single sided version (cut on one side) for older Contico Tuff Boxes. Normally they are double sided and the two are not interchangeable. If in doubt, compare the line drawing of the keyway in the example key blank picture to the face of your lock and if it is correct, this should match. Key will be cut to code and ready to work in the lock.
