...strange goings on.? the doors will refuse to centrally lock from the inside and the key has to be inserted in the lock and reset the thing, then it will work for it's own predetermined time then act up again. Then out of the blue, the remote refuses to open or close the doors (for about 2 months), then one day the thing just starts too work again...the battery was replaced during the time when it was not working. then one day the doors just wouldnt lock (with the keys nor remote), by the evening all was well.
