The key fob is powered by a small transmitter that sends out an extremely short-range signal to a receiver inside your car. Its primary function is to permit your vehicle to recognize the key fob, then open its doors when you come close to it, and then start when you press the ignition button.
The problem is that interference can interfere with this communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it could block you from unlocking your vehicle.
Other electronic devices that utilize the same frequency as the fob might also interfere with its signal. Garage door openers and tire-pressure monitoring devices may be affected. Even a transmitter inside your home could be interfering with the tire pressure, but this isn't easy for a professional to test.
Your key fob could require reprogramming. This process requires the transmitter in your fob to become recognized by the receiver inside your Mini and a specific code is assigned to each pairing.
