Central Locking

Can someone please advise? I am finishing off restoring my 1991 Cabriolet. When purchased the central locking was disconnected I have sorted connections and it is working but when I lock car it keep OPENING itself immediatley again. I want to get door cards on and finish and drive but this is a pain.

Would like help from someone who's been here before! Thanks
