Review on CAT4M Code Alarm 915MHz FCC H50T59 H5OT59 - 4-Button Replacement Transmitter Remote by Derrick Bellando

I selected this code alarm remote as instructed when looking for the FCC number on the back of my current remote. When I tried to program it according to the instructions that came with it, it didn't work. I found the number on my alarm module, looked it up and found that this remote does not work with this module, although my current remote does. I chose this one because of the price. My original remote is $70, this one is $29.
