I did a trial of this on my 2010 and it worked pretty well. I recently upgraded my iphone app and now I cannot remotely lock my doors using the app. I called support and they are telling me that my G55 is not supported for remote door locking. I'm 95% sure that I've successfully tested this in the past. Anyone with a G500/G550/G55 (2010) able to confirm that they were able to remote lock their door using the iphone app?
