prolly locked it after he opened the trunk and then set the key down to grab sumthin and then forgot about it. i almost did it once lol

and how could you break into an a4/s4 with a screwdriver?

 

no, only way to get your car unlocked is if you go to the dealer give them your vin# with proof of ownership and they will order you a new key, then get the car towed some how to the dealership and they can program the key, then you can start your car. I know cuz it happened to me unlock button does not work when using a slim jim car locks down when alarm goes off. car cant get towed cuz hand brake was on and is allwheel drive. too expensive to replace the glass.
