Passenger door locks dont always work on 2002 BMW 325i

When I use the driver door key lock or the inside switch the doors do not always lock/unlock. It takes several tries to get it to react. Obviously everything is working mechanically because they do work eventually. Any help is VERY appreciated.

Thanks but the same happens with the internal lock/unlock button. It has the exact same behavior. Any other suggestions? I appreciate your response.
