Boxster S 2000 passenger door problem

[Mikluuutus]

Having problem with passenger's side door, door doesn't open.

Using remote to lock the doors, everything goes locked. Trying to open the doors, everything opens but passenger side door doesn't, car give 2 beeps.

Door won't open from inside or outside handle. It just refuses to open. When pressin opening button from the remote, you can hear something is moving there but door refuses to open. Been driving 3 weeks without getting passenger door open, then suddenly one day it opens normally. After driving locked the doors -> again same problem, passenger door won't open. Used car for two weeks and one beautiful morning it opened again. What's wrong with it, what do you suggest to do?

Here is the picture of Alarm input signals, when both doors closed: http://www.amigosracing.eu/wp-content/uploads/2013/10/021013_MLM991.jpg

I'm wondering why driver's side says door secured but passenger side don't?
