Key remote/power door lock won't work???

[mk4r34]

I've done a search but,still haven't got a solid answer...first passenger side door won't open from inside..took it apart to find out the previous owner ghetto rigged and made a latch for the handle...long story short we took that piece out so now it won't open from the outside but,we got it to open from inside now...on top of that the power doors unlock but,don't lock!!.. my key won't lock and now the alarm doesn't seem to be on even when I manually lock it...I saw the sensor to the latch hanging but,it seemed to work before...any ideas??..can I glue the sensor back cause it seemed to broke off??
