I live in an apartment building and was given a fob that opens my apartment garage door and doors in the building. The fob takes specific lithium coin batteries and lately has been acting worse, I practically have to replace the batteries every day to use it. I had my Flipper Zero read the signals (the fob does one for garage door, one for the other doors) and I now use that to get into my building. Instead of having to buy two new lithium coin batteries every day, I just have to charge my Flipper Zero every few weeks. I heard the Flipper Zero had other uses, and I did scan some other things with it, but I got it in the hopes that it could handle my garage door, and it does.
