I think you can activate auto unlock when you stop and go into park. All you have to do if I remember correctly is go into Accessories mode (Push the start button without pushing the brake) and hold the unlock button for 5 seconds. Once you hear the beep you'll have it activated. Then you can start the car fully by pressing the brake and then the start button. If for whatever reason you decide you don't want it to unlock when you go into park, you can do the same steps, but hold the lock button instead of the unlock button for 5 seconds.
