'04 XLR Fob /Receiver Problems

Bought a beautiful XLR. It only came with one fob. I went online and found a second. I asked the mechanic to calibrate it. He blew up both. Now his friend who says he’s more experienced in the problem says I need a Remote door control lock receiver #25940664. It has to be that number. I can’t find one online. Any ideas where I can look? I’ve tried ebay, google search, etc. Also if you can give me any help with my Fob problem my email is above. (I’m 80 y/o. My daughter is typing this for me and can help with questions).
