Interference

The key fob is powered by a small transmitter that sends out the signal in a short distance to a receiver in your car. Its goal is to enable your car to recognize the key fob, unlock its doors as you approach it and start when you push the ignition button.

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

Other electronic devices that operate at the same frequency can also interfere with the fob's signal. Garage door openers or tire-pressure monitoring devices can be affected. Even a transmitter in your home could be interfering, but this would be difficult for professionals to test.
