My central locking defaults to lock all the time, even when i use the key fob and alarm / operate the door system from in side manually or use the key. It normally happens within a few secs of trying to open it but will mostly relock its self. (note i have to pull open the door very quickly to gain entery).

this fault is caused by a faulty door actuator you will have to replace

i had the same fault myself, its a door actuator fault, you will have to take a door pad off and disconect the actuator (one side at a time) to find which side is at fault! either try some wd40 into the actuator or replace it, hope this helps
