Can't lock my car :D

[willd]

And.....*drum-roll*......todays problem, IS:

I activate the remote, the car locks. Then about a second or two later, it unlocks everything again, and sounds the horn twice, like there's a door or trunk open or something.

Of course, I've checked all the trunks doors,.....they're all fine of course.

Where are the sensors that sense the trunks are shut......?

Would the car thinking the trunk being open, stop the roof working.......I'm suspecting the two might be linked.....or maybe my entire goddam car is a money-pit.....
