Question:
I would like to purchase 3 sets of this lock set, but if possible I would like all 3 sets to have the same key number. Would it be possible to request that the etrailer fulfillment staff send 3 sets with the same key number? It would be so nice to have all three of our trailers have the same key!

Expert Reply:
Hey Heather, unfortunately the Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set # 3794DAT is keyed unique so it's not available to be keyed alike.
Instead, you'd have to use something like the Master Lock Set # ML44VR which come with all three locks keyed alike. This kit also works with 1-7/8", 2", and 2-5/16" ball couplers and 1 1/4" and 2" trailer hitches.
If there is anything else I can do for you, please feel free to drop a comment and let me know!
