On mine all it takes is to remove the 4 screws (2 at each end) that hold it to the door. I know because I installed it myself, but perhaps yours is installed with some adhesive as well.
As it happens mine stuck in the down position yesterday, so I took it off and was going to open it up to try to figure out the problem. However, after manipulating it a while it decided to start working again, so I re-installed it.
