Hi rayncc....its pre- ownned car and its my 1st Bimmer. Therefore, not sure if it had similar issue....
Hi wideawake......I guess so long the comfort access key is within the radius, u should b able to unlock/ lock the car without physically touching the door holder ( in your case water hitting the door holder).... in my case I m unable to unlock/ lock using the the remote manually unless it s near to my car ( approx 1m)......strange!!
