Hey Oliver, welcome back. The InfiniteRule Lock for Cast Demco eZ-Latch Trailer Couplers item # IR66FR can not be keyed alike.
To get multiple locks keyed alike that are compatible with the Demco EZ-Latch like item # 12660-97SP, you'll need to go with our etrailer Surge Brake Coupler Lock item # e98887 for a 2-1/2" span or item # e39PR for a 2-3/4" span.
Please note that you will need to purchase the locks at the same time and select the "keyed alike" option from the drop down above where it says add to cart.
What kind of trailers do you have?

So the etrailer Trailer Coupler Latch Lock - 2-3/4" Span - 1/4" Diameter - Chrome Part Number: e39PR will fit the Demco 2 5/16" cast coupler, right? If so, I'll buy two of them right now! Thanks, Oliver
