Garage Remote or Key Entry

We have a building of 10 units. The chairman/treasurer of the body corporate – who has held both positions for over 20 years and is not on email, does not believe in remotes. When I moved in he advised me there was no remote access so we all use a key, therefore driving in and out on the RHS. In August I found from discussion with the technician servicing the garage door that there has always been remote access available so I bought a coded remote as did five other owners in the building.  The chairman/treasurer had this deactivated as he believes remote access is not secure and we must use the key. I have written advice from the service company that they advise remotes are safer than keys.  What action should we now take?
