Cause of Not Functioning Car's Remote Key

Car's remote key sometimes do not work even if the battery is still good . The problem generally arises when the vehicle is in a location that has such a strong electromagnetic field around the radio station or television .Technically , the remote is not necessarily the same vehicle with the frequency emitted by a radio or television station . But keep in mind that radio waves have a frequency harmonics .Frequency of ' wild ' is a multiple of the frequency generated by the primary frequency . Remote vehicle would be problematic if the harmonic frequency of the transmitter accidentally ' fall ' on the same frequency .Because the transmitting station has a great power to be able to emit its broadcast , it will automatically force generated harmonic frequencies are also strong enough to cause interference .The only solution is to keep the vehicle from a radio transmitter in order to reduce the harmonic wave interference .the Jaguar and Land Rover owners often complain about the non-functioning keyless entry feature by a very trivial problem . Usually remote ( keyfob ) bagged in a position stacked with other electronic devices such as cell phones .Mobile phones also emit radio signals at certain frequencies that are potentially interfering signals emitted by the remote . Therefore, he suggested to the owners of vehicles with features remote keyless entry for bagging it separately and not combined with equipment that emits electronic waves .
