Please help! Trunk won't open

I need to figure out how to open my trunk. Please watch video:


My rear seats do not fold down. How can I get my trunk open without damaging my car? Is there any kind of cable I can pull to get it open? As you can see in the video, I already tried the valet key, but it only turns about 45 degrees and then gets stuck. Any other suggestions??

I do have a lot of stuff in there, but no issues before. I'll try pushing down while turning the key. The problem with the key is that it only rotates about 45 degrees (won't turn the full 90 degrees to open)

No luck pushing down. And no dead bodies either

I am getting desperate though. Is there no cable or something I can pull to unlatch the trunk? I know about the one on the inside, but that doesn't help, as my seats don't fold down.

What would the dealer do differently?

Check out youtube "BMW E36 trunk lock fix" it might help to keep it from happening again after the trunk gets open.

Thanks, found that video.... would try that fix, but first I have to get it opened. Called the dealer and they said $100 for "diagnostic". Asked if they would be able to get it opened, and they said they didn't know. So now I want to exhaust all options before paying $100 and having the dealer tell me they can't open it.

Have you tried a combination of pressing the trunk button just left of the steering wheel while someone else uses the key,as seen in that youtube video it seems like there is a part of the linkage that obstructs the movement,just a guess,let us know good buddy,peace.

You may think that this is a joke, but it's not.

It's possible that something in your trunk is jamming the mechanism.

The mechanism is at the back of the trunk. So, get the car up to 30mph and then stomp as hard as you can on the brakes. You want a full on ABS stop. The force of this might be enough to shift whatever is causing the problem.

Hard cornering or acceleration might do the trick too.

You may even want to try doing this while pressing the trunk release button, so long as you do it in a safe place. The combination of the g forces and the mechanism trying to move may free whatever is obstructing the mechanism. Find an empty parking lot somewhere and see what you can accomplish.

Here's another idea. The trunk on that car has an escape handle on the inside. It's item 7 in this microfiche.

http://realoem.com/bmw/showparts.do?...77&hg=41&fg=60

Maybe you can get a coat hanger in and snag that handle? I'm not hopeful, though, because you've already tried to activate the mechanism three other ways. I doubt if the handle will have any more success.

Here's the last option. Your seats don't fold, but your car has the same frame as the cars that do have folding seats. That means that once the seats are out of the way, there will be an access hole.

It'll be a big job, but you could unbolt and remove the rear seats.

I am guessing you don't realize this, but the trunk release button is disabled if the car is moving more than a 1 or 2 mph.

Every day I let out one of my passengers to grab something out of his car. I can't tell how many times I have hit the trunk release while slightly costing forward to a stop. Nope, it doesn't do a thing unless you are stopped.

I'll give this a try today, if only because it sounds fun
I do have golf clubs in the trunk of my car, so perhaps something did get jammed in the mechanism.

As mossman mentioned, the trunk release won't operate if the vehicle is moving, so I'll have to wait until after I'm stopped to try again.

Thanks everyone for your help. Will report after lunch today.

Aha! That is a source of desperation.

But....guessing vehicle was at rest when you tried the valet key. So how to remove the rear seat back. Bolsters out, are mounting bolts accessible?

It is good to work with one's hands. It is a pisser to find there is no pass-through. TXFred, how do you know all seat back frames are the same?

Here's what I found on Realoem for the back seats. This is the model of seat that doesn't have a passthrough or folddown option, so I think it's the right one.

http://realoem.com/bmw/showparts.do?...91&hg=52&fg=20

Item 2, Supporting part, backrest, looks like a plastic insert that covers the hole and supports the seat.

Whatever bulkhead lies between the trunk and seats would be part of the vehicle's unibody. It doesn't make sense to build one unibody with a full bulkhead for the non-folding seats, and build a different unibody for cars that have a passthrough between the trunk and cabin. Ergo, all E90's have the passthrough, but some of them cover it with a big plastic panel.

Hopefully the mounting bolts are accessable from the cabin, and not from the trunk.

My only other suggestion is "outside the box." Get a friend on a skateboard with the valet key. Tow him behind the car at 30mph. On the count of three, have him turn the key in the trunk lock while you stomp on the brakes.

Be sure to film this for YouTube.

Assuming he survives the experience, you might get your trunk open.

Frederic

This is what I would try. Def worth a shot, and free

Bottom usually come out very easy, just pull up then out.
Back will be more work, but worth it if it works.

Figured I'd give an update... So took it to the dealer. Charged me the standard "$99.99 diagnostic". I asked if that would guarantee anything, he said no. So... after a few hours, he calls me back and said that I would need new cabling as well as a new lock actuator. About $1,000. Asked him if he got the trunk open, he said no.

Then I asked him... well, how do you need I need new wiring, and he told me that his mechanic was able to take out the back seats and see something was up. Called him a liar, since I have a sub and had a TON of stuff in the trunk (golf clubs, towels, backpacks, etc), which would have made it impossible for him to see the locking mechanism. He said he would call me back.

After about an hour, he calls me back and says: "you won't believe it, but the guys were able to open it, and it's now working. Doesn't mean that it will keep working, but if you want to get some stuff out of the trunk, now is a good chance.

So picked up my car and sure enough, trunk was working. HOWEVER, I looked at the lock and saw it was cracked on the side (my guess is this is the issue). Bought a new lock actuator for $60 shipped and voila!

Here's a picture:
