Replacement Key for Master Lock ML389DAT Trailer Coupler Lock


I found a previous reply to this query but when I search for the recommended part number I am not getting any results. Can you help?


Expert Reply:

To obtain a replacement key, you'll need to know the 4 digit code that was stamped on the key. You'd use part # MLK1. On the product page, near the 'add to cart' button, you'd need to type in the 4 digit key number.
