Interference
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 primary function is to allow your car to recognize the fob, and open its doors when you approach and start when you push the ignition button within.
Interference may sometimes hinder communication. For instance, if have your second-generation Apple Pencil charged while you're holding the fob, it might hinder you from unlocking your car (via iGeneration).
Other electronic devices that use the same frequency as the fob can interfere with the signal. Garage door openers or tire-pressure monitoring devices may be affected. Even a transmitter at your home could be causing interference with the tire pressure, but this is difficult for an expert to test.
Your key fob might need to be reprogrammed. The transmitter in your key fob has to be recognized by the Mini's receiver. A unique code is used for each pairing. The fobs will typically need to be programmed after being removed or replaced, if you purchase a new one and, in some instances, when a battery is changed. Follow the instructions in your owner's manual to change the programming of a key fob. You can also seek assistance from a dealer.
