My car randomly won't unlock the door, but turning the key causes the window to go up and down. When it does this, I turn the key to lock and then it unlocks. This doesn't happen very often.
On a related note, fairly often the door opens, but the rest of the car stays locked (trunks, gas filler). This happens more often. If I start the car the red light on the lock switch lights up and I can use that to unlock everything.
I don't even have keyless entry.
I think Porsche made the locking system too German.
