My actuator failed locked, only realised when I came to need fuel. Car was still in warranty but I didn't have enough fuel to get to nearest dealer, Seat didn't want to know unless I could get it to them. Got it open at home in the end without damaging anything other than the faulty part, fitted a new one and all good. Needless to say I now carry a roll of masking tape, junior hacksaw blade and some plastic wedges in the car.......... Why the actuator opens every time you unlock is beyond me, you should be able to configure when like you can with doors.
