Years ago I wrote a simple program that reads from a IR photo diode to a PC parport pin,
or any other thing you have, to record the IR commands from my cable modem.
https://panteltje.nl/panteltje/pic/ir_pic/
 scroll down to 'finding out your codes'.

it saves those as files, one for each commad (you type the code on a remote and record it).
The top of that site shows you how make a module to then transmit those codes, but that requires a micro.
If your PC is fast enoiugh it can do that too.

Hacking cars .. well you know...
I had a similar system for listening and recording RF codes and then re-transmitting those,
with tx and rx modules I bought,  basically a replay attack.
