Master Lock has always been confusing with the 379. They had a great little lock, available in either keyed different or keyed alike. Then they changed the style of the keyed different, but kept the keyed alike the same. Both still had the same model number. Now they have come out with a new model, the Master Lock #389, which is the old style 379 in keyed different and painted bright red. If you don't need keyed alike or rekeyable, give this lock a look. This style has always been a good lock and we are glad it is back!
