It will be very hard to unlock the car trunk, and you will have to put your bags down to unlock the trunk which might give someone an opportunity to run with your goods. But with keyless entry you will safely put your goods on the trunk by just press of the trunk button on your keyless remote.
Apart from that, it is mistake proof. At some point you may find yourself that you forget to lock the car door when you are using standard. With this somebody may interfere with your car, and you will have to go back and lock it even if it is raining cats and dogs. But with keyless entry system you will be in a position to shut the car door even from the house.
