Title: Can't program itself based on another transmitter
Review: I was hoping this thing would just be able to pick up the signal from another transmitter and learn it (like a universal VCR remote). Since I live in an apartment building I don't have access to the garage door base station, and the remotes we have don't have the security codes written on them (and, upon opening them up, don't have DIP switches). I suppose it would work if you did have access to your base station or you knew your security codes. In my case, I had neither.
