Interference

The key fob is powered by a tiny transmitter that transmits signals of a short range to a receiver in your car. Its goal is to enable your car to recognize the fob and open its doors when you come close to it and start when you push the ignition button within.

Interference can occasionally interfere with communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration), it could prevent you from unlocking your vehicle.

Even a transmitter in your home could be causing interference with the tire pressure, but this would be difficult for a professional to test.

Fobs need to be reprogrammed after they have been disconnected or replaced, after purchasing a new one and in certain cases when the battery is changed.
