Changing the battery in your key fob is one of the easiest solutions.

The key fob is powered by a tiny transmitter that sends out signals of a short range to a receiver located in your car. Its function is to allow your vehicle to recognize the key fob, unlock its doors as you approach it, and then 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 could prevent you from unlocking your vehicle.

Other electronic devices operating on the same frequency may also interfere with the fob's signal. Garage door openers or tire pressure monitoring devices could be affected. Even a transmitter inside your home could be causing interference however it is difficult for professionals to test.

It's also possible that your key fob just needs to be changed in its programming. The transmitter inside the key fob needs to be recognized by mini cooper spare key's receiver.
