Can the Master Lock Trailer Coupler Lock # 377DAT be Rekeyed


is part # 377DAT rekeyable?


Expert Reply:

The Master Lock Coupler Lock, # 377DAT, is not rekeyable. Master Lock does not offer replacement lock cores for this particular lock. If you know the key number that was stamped on the original keys, you can order replacement keys using the Replacement Key for Master Lock Coupler Locks, # MLK1.

If you do not have the original keys and the lock is stuck on your trailer, you can drill out the lock core to remove the lock, but you would need a new coupler lock to secure the trailer. If you purchase another Master Lock Coupler Lock, # 377DAT, I recommend writing down the key number so you can order replacement keys if needed.
