Craftsman Garage Door Opener Remote Repair

My Craftsman pocket size key chain garage door opener remote quit working.  In this video I take it apart, diagnose the problem, and repair the remote.  I also show how you can check if the remote is transmitting using a software defined radio dongle.

I found a bad solder joint, but the solder joint was not cracked, it looked more like the solder never properly flowed onto the part lead when it was soldered, so that was probably not the reason the remote quit working since it was likely manufactured that way and had been working for a couple years.  

Shortly after I bought it, the little plastic loop on the corner where you attach your key ring broke off, as I am sure happens to every single one of these things ever manufactured, so I replaced it with a small loop of large paper clip wire that I bent into a loop shape.  It turns out that one of the ends of the wire loop had been hitting the circuit board and wore through a trace.  I show how to repair the trace, resolder the bad joint, and fix the problem with the wire loop so it doesn't happen again.
