im suffering big time at the mo with the same problem.......................
plus the added bonus of the central locking not working (frozen???)
everytime it freezes i have a right faff about.
this moring i managed to climb in through the passenger door(the only 1 i could open this morning)
then started the car up,thinking some warm might help... lol lol lol
went back out 5mins later and all the doors were locked, now on mine if you cant get the drivers side door open within a short peroid,it locks itself again
i take it ,all the central locking is via the drivers door??? or is that a feature of my full closure alarm?

either way its really starting to p**s me off.........then when the locking finally gives in the bloody doors are frozen solid anyway..ggrrrrrrrrrr
rant over
pat.
