New Owner have a question about new key programming

[cbjr]

I have a 2012 Yaris Sedan which I figured was only offered as fleet vehicle when it was new but pretty much the same with 2011 sedan. Only issue I have is it didn't have keyless entry. I have power locks, 2 keys but no remote. I don't have immobilizer since ignition tumbler is just metal. So I did some research and find a door control module for the car and got the appropriate key for it. model/part number for the module is 89741-52290 which is a FCC: MOZB21RG so I got myself a key (MOZB41TG). Plugged in the receiver to the connector behind the drivers side rear door and used the regular programming sequence. (door open, put key in/out close/open door etc usual steps). Problem is it seems like accepting the key program and confirms but then remote doesn't operate doors. The receiver module is from a 2008 sedan Yaris. I even went a head and pulled another remote unit from a scion TC from the junk yard that has same connector and FCC ID. it does the same thing.. Am I missing a step? or maybe the body control unit didn't like the receiver modules?? is there a way to reset it? or try techstream to make them talk each other? it is frustrating to program it and think its done and next moment doesn't work.. I know its a minor annoyance not to have keyless entry but here up in northeast Ohio I don't want to get stranded when my key hole freezes. It is really frustrating getting it so close to working but cant make it work..
Any advice would be appreciated!
