Expert Reply:

If you know the key number that came with your Master Lock Trailer Coupler Lock # ML389DAT then all you need to do is order the Replacement Key for MasterLock Coupler Locks # MLK1, and be sure to input the correct key number on the page prior to ordering.

If you don't have a record of your key number then you'll either need to call a locksmith to make a copy for you, or you'll need to order a completely new coupler lock, and you'll want to record the key numbers once you get it.
