Hey guys.....need some help. I’ll drive to the beach with my board on the rack. I get there, park, need to leave my phone in the car and lock it while I go for a surf. How do I lock the car with my phone inside? Will the key card lock it? If so, if someone comes to the driver’s door handle and tries to open it, will the door unlock because it senses the phone Bluetooth inside? If the door stays locked, then I just have to find a place to hide the key card while surfing, ehh??
