Interference can 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 that operate on the same frequency as the fob might interfere with its signal. This could include garage door openers and tire pressure monitoring systems. It is also possible that an RF transmitter in your home might interfere with the fob's signals, although this would be difficult to pinpoint without the assistance of a qualified test.

It's possible that your fob just needs to be modified. This will require the transmitter in your fob to be recognized by the receiver in your mini one key cover and a specific code is assigned to each pairing.
