Hello Ladies and gentlemen,
I am trying to find the location on my key FOB for the antenna, so I can modify the range with a length of wire. Does anyone know where this point might be?

 

It’s likely printed into the card. If you did know which line it is, you would have to drill into it to solder a new lead. I’m not sure on this but adding wire may change the tuning on it and make the range worse. Antennas are tuned for the circuit it’s being ran off of similar to a CB/gmrs/etc.
