Dip switch or rolling code garage door opener?
I'm pretty confident that it's of the "rolling code" variety with strong encryption, so replicating it isn't feasible.  

I suspect (based on the Microchip logo, pinout and TSSOP-14 package) that it uses this specific chip: "MCS3122 Advanced KEELOQ® Technology Encoder", just with a different part number on the manufacturer's request.
