I reversed out the IR codes for some devices when I wanted to control them using Alexa. While my Alexa control method is no longer supported the way to reverse the codes is still applicable.

I used an D1 mini board based on the ESP8266. You can get these for a few bucks from many sources. They program over a USB cable, and are very well supported when it comes to libraries. You can tack on an IR receiver such as a TSOP4838 and when you point an IR transmitter at it the transmitted codes will appear in your debug window.

Once you have the codes in your pocket you can reuse whatever micro you used to make a controller.

This kind of thing has been done so many times you can just Google a solution.
