The problem I had is that the LoPSTer board was shipped for 433, but in the States most of these use 315 mhz.
There is a place on the board where you will see a capacitor soldered at the frequency range. I tried moving it to the 315 slot, but it still did not work. I have minimal interest in the RKE function anyway, so I have not pursued rectifying the problem, nor am I sure how to do it. Are you sure the keys you have are working on 433 ?
