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!

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!

Hey Heather, did the keyed-alike Master Lock set work out for your trailers? Knowing how it fit your setup could help others looking for an easier way to manage multiple locks.
