There was a problem with the reader because sometimes we had to bring the fob 2 or 3 times to open the door. It turned out that the problem lay in cheap nameless keychains. (Slim gray ones that are blank on the back and have a 5-digit number on the front.) These HID fobs cost 10x the cheap ones, but they work the first time, every time. Spend your money and buy the right thing.
