I did a quick search but didn't find anything. My apologies if this has been covered elsewhere. I have a 2009 135cpe and decided to install the factory alarm. I left the trunk open after I disconnected the neg. battery terminal and proceeded to install the parts. When I finished, I reconnected the battery and buttoned everything back up. But when I went to shut the lid, it wouldn't latch. I manually engaged the latch and then used the key fob, the trunk release button inside the car, as well as the finger points above the license plate to disengage it. The actuator seems to be functioning but won't latch when lowering the trunk lid. Everything else with the car seems to be functioning properly (including the clown nose for the alarm). Thanks in advance for any ideas.
