2 KeylessOption Replacement Keyless Entry Remote Control Key Fob Clicker Transmitter 3 Button - Black

I purchased these replacement fobs for our F350 Super Duty Ford and while they look the same, we have tried every trick provided in the manual, online and with customer service and cannot get them to work. We have replaced the batteries and they still will not pair to our truck. While they seem to be made well on the outside, I am not an circuitry person so have no idea if they are made well inside. For now, I think I'll use them as decorations or something and find another set that will work.
