So I took my 2011 to a stereo shop yesterday to have some work done. They were doing the final tuck and hide on wiring when it started to rain, and asked me to move the car under their carport. Tech pushed the button to close the trunk but it didn't fully close, so he finished closing it by hand. When I started the car the "Trunk Open" message was displayed for less than 5 seconds, then went away. However, after moving the car, there is zero response from neither the interior or exterior button, nor from the remote fob. Tried doing the electrical bypass behind the back seat without any response either. It seems as if the computer doesn't understand the truck actually is closed and won't activate the latch. Help! Is this something I can reset with my code reader, or do I have to suck it up and take it to a shop with the full computer ability? Thanks in advance for any help.

 

Don't know but on my 2014 model when this happens I can sort it by using the cars buttons. So no help to you. But I have seen where the car gets confused about the state of the trunk when I push the trunk closed with my hand. So I try to avoid that if possible.

If it was my car I would unhook the battery and touch the negative and positive terminals together for a minute and wait another 20 minutes or so to make sure everything is dead and unpowered. Then reconnect the battery and see if anything has changed. Yes you will lose some programmed features like the 1 button windows but they can be reset fairly quickly.

Surprised that the plug under the rear seat did not work? If you look at the diagrams and apply both 12 VDC and a ground to the right pins. That plug bypasses the entire car and is connected directly and only to the trunk latch. Did you only apply voltage and not the ground?

It seems like the trunk is not in locked state, because you got "trunk open" message. Thats why it dosent open by button.
Thre was propably someting in the way and thats why trunck stopped because it sense an obstacle. Then the tech pushed it against that obstacle and now trunck is stuck with obstacle half locked. One member had same situtation and they got trunck open by brutal force: 2-3 man put fingers on seam and lifted/nudged hard.

 

I wonder if he got into the trunk from the back seat and pulled the emergency release cable?

the battery is in the boot so not able to get to it

 

Im going to have to try using the connection behind the seat myself. The stereo shop were the ones that tried it, but I'm betting dollars to doughnuts they didn't get it right. I will have to pull the seat back and give it another go myself. It would be great if there was an actual video of which probes to which pins was correct.

 

Actually you can and it has been done many times? You have to remove some rear seat stuff and fish a wire into the trunk to catch the emergency release handle. Difficult but not impossible. One guy even thought ahead and ran a cable from the emergency handle up and under the rear seat. So if he gets locked out again he has a mechanical way to open the trunk.
Pretty smart thinking!

Have you done any searches? We have a massive sticky thread on how to do this and no video is needed? It's very simple once you look at that thread?
