My small key fob to enter my building and elevator doesn't work. The outer shell split open in two halves a while back, and yesterday the chip and coil inside fell out and was lost.
Today I found the chip and coil on the ground at work, but when I try to use it, it does not work. It just doesn't want to activate. The thing looks to be intact; the chip is in the middle, and there are two small copper wires leading from the back of the chip and wrap around the coil ring.
Is there anything I can do, or is it likely permenantly broken? I was excited when I found the insides, since a replacement costs $75, and no security places in town want to copy this for me (I could copy a room mates, they only activate to get in the building, not needed to egress, but again, shops wont duplicate it for me)
