Noticed that when closing trunk a low ringing sound is emitted. It persists for about 10 seconds after the latch is closed. Does it have to do with key fob? Because I keep a spare smart key fob in my purse in the trunk and only when that purse with the extra fob is in the trunk then the trunk emits that noise, otherwise it doesn’t do it.

If you leave a key fob inside the trunk, especially a spare or second fob, the car will detect it and emit an audible warning tone to prevent you from locking the keys in the car. Let us know if you need anything else.
