Unlock-by-touch, which is standard on Q50, enhances the convenience of Intelligent Key by eliminating the need to press a request switch when unlocking the driver or front-passenger door. Instead, users can simply slide their hand inside the door handle to unlock that door if a registered Intelligent Key is within range. Pressing the request switch then unlocks all the doors. To lock the doors, simply touch any outside request switch once.
