Recently my Genies Coupe Smart Key quit working. Good battery at 3.3v. But would do nothing and I had to use the fob holder to start the car. It seems to be a fairly common issue as the cars get older and the parts swapping then starts wit antennas and receivers.
Turns out mine and others was just corroded fuses that showed good but apparently had enough resistance to kill the smart key system. I too the fuses out and cleaned them and sprayed some cleaner in the slots. The put the fuses i and out a couple times.
Works like new.
The fix was from another Hyundai site.
