I bought an RF Shield, it works perfectly, but I would need the unlatched version. Can I order it? (With PT2272-Mx instead of PT2272-Lx.)

The address of the keynob should be set the same as the shield's, did you change the address of the keynob? the one we have has the original address with all pins floating, unless you have change the address of the keynob, or you just need to unplug all the plugs on the shield.

I am thinking about buying this and a few key fobs because I would like to hook it up to my Arduino Uno and use 3 different key fobs that would each send their own signal to the Uno. I am thinking of a simple bean counter where my Arduino would know button 1 was pressed from one key fob, button 2 was pressed from another, and button 3 was or wasn’t (or whatever, you get the picture). Does this sound reasonable or will the incoming signals from each key fob be indistinguishable?
