It sounds like you have a MasterLock Trailer Coupler Lock # 377DAT and a Master Lock Adjustable Trailer Coupler Lock # 2847DAT . In order to determine which keys you need, you are going to need the number that was stamped on the original keys and not the numbers from the locks. Unfortunately that is the only way to get replacement keys for these two locks. If you wanted to replace them with new locks, you could go with the exact same models as replacements.

If you have the numbers off of the original keys, you can order replacement keys from the Replacement Key for MasterLock # MLK1 . You will need to put those key numbers into the field on the right hand side where it says Key Number and we will send you the appropriate replacement keys.
