Interference

The key fob has a small transmitter to send a short-range radio signal to a receiver within your car. Its function is to allow your vehicle to recognize the key fob, unlock its doors when you come close to it, and then start when you push the ignition button.

The issue is that interference can sometimes hinder the communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it could stop you from unlocking the vehicle.

Other electronic devices that utilize the same frequency as the fob may interfere with its signal. Garage door openers, or tire pressure monitoring devices could be affected. It's even possible that an RF receiver inside your home may be interfering with the fob's signals, but this would be difficult to diagnose without a professional test.

When the old battery is replaced, it is a good idea to test the fob's function before driving the car.
