Greetings, I stumbled upon this forum trying to find an answer to my question. The plastic casing on my car's key fob remote broke and I got the idea to practice my machining skills and fabricate a new housing for it out of metal. I found some scrap brass and was succesful in making said case. However, it came with some unintended side effects, namely where my remote once had decent range I now have to be literally two feet away from the car for the remote to work. I have made the case as thin as I can, but my theory is the metal case is blocking the RF signal. Is there anything I can do to improve the function of my remote? I can simply by a new plastic case granted, but I would really like to make the one I fabricated myself work. . .
