In our 2024 LCFE the key will stop working. I need to put it up close to the switch to get it to start. I tested the spare key, works fine. I pulled the battery out of the non working key and tested it 3 volts, OK. I put the battery back in and it work like new with the same battery. I tried the spare for a while and had the same problem. I think it starts to work because I am rebooting the key. This has happened 4 or 5 times. Has anyone else have this problem? I know if I take it to the dealer it will work fine, No Problem found.
