Is this true, or is it just a case of two keys on the same ring interfering with each other's signal when trying to start a vehicle? Thanks in advance...
there is NO way that is true
the "CODE" is PERMANENTLY encoded to that key and can't be altered by any proximity issue(s)
otherwise..... keys would become "useless" all the time
since almost every car/bike manufacturer uses coded keys now....
you can bet they are VERY STABLE
