Front Trunk Lid Open

I purchased a 2005 Carrera2 997 about three months ago and have experienced finding the front trunk lid open when going down to the garage. I am positive I left the lid shut when exiting the car, but on two separate occasions I found it ajar when I returned to the garage. Luckily the trunk light must have a timer that turns off the light after 15 or 20 minutes. My key remote activation button is not the sensitive type. When opening the lid I have to hold down the button with effort for a few seconds before the lid responds. I was wondering if anyone out there has had a similar experience. The first time it happened I didn't think much of it, figuring it was my error. After the second time it has me wondering if there is a flaw of some sort involved. Thank you for any help in this mysterious matter.

I have had something like that happen when driving. The lid latch would release and the trunk warning light would come on. I found that there was a little dirt under the sill switch holding it on the edge of opening. Driving it made enough vibration to activate it. Maybe yours has dirt under it that activates the switch when you close the door? Try holding the switch up and vacuuming under there.

Thank you for the response FPB111. I never had the latch release while driving. Sounds like that could be a dangerous situation. I will certainly give your suggestion a try. I am finding that the problem could also be in the sensitivity of the remote button, resulting in an unintended latch realease activation.

Thanks to everyone for all the responses. They helped me solve the mystery of the open trunk lid problem. I usually carry the key in my pocket because I do not have any special fobs or other keys attached to it which makes it easy to carry around, yet probably easier to lose. As I was sitting at my desk in my home office, I realized that with just the right motion of sitting, standing, or crossing ones legs, the trunk activation button could easily be pressed against anything in my pocket or even a fold in my jeans. I took the key from my pocket and depressed the trunk button as a test, immediately running downstairs to the attached garage. Sure enough, the trunk lid was open and the doors were unlocked with the courtesy lights illuminating. I was surprised that the trunk button also activated the doors, but after a minute or so the doors automatically re-lock, and the lights slowly dim to totally off. The real surprise was that the key button worked from a distance of about 60 feet away and the second floor of my condo. The key looks to be of the original 2005 MY vintage, but I do have a spare which appears to be from the latest generation of Porsche 997 stock since it is heavier and in perfect mint condition. Now the key stays out of my pocket while at home which is a good idea anyway. I found that the friction created from sliding it in and out of my pocket wears off the red color of the Porsche badge on the key. At least that was my past experience with my previous 2001 996 Porsche keys. Hope this information may help someone else that has experienced the mystery of the open trunk lid latch.
