2004 range rover hse remote start issue

I've got the Remote Start in my Range Rover all set up and working properly, except for one instance. After a long period of time (like overnight, for example) the truck does not want to start unless the door opened first. It's like the immobilizer won't allow anything to happen unless the door opens first. Has anyone else experienced this? Anybody have any ideas to get around it?

If the remote start Has an alarm disarm wire try pulsing the door trigger wire before remote start and see if this helpstriniforever

At the time they were part of Ford, isn't Triniforever on the right track here? Aren't there similar issues with Fords?
