How do I open my trunk? No power.

So I took out my DME to send out to powerchip and locked the trunk with the negative cable unplugged, now I can't open it to connect the cable, the DME is not back yet but I don't think it will open even if it's connected... So, how do I open it? Key doesn't open it either...

Put the key in, turn it until it stops, and then continue to turn about 1/5 of a turn. It has some resistance, so you think you can't.

The key will be parallel to the ground, just like when you lock the trunk, but to the other side.

Read the owners' manual.

Whenever a remote doesn't unlock doors or trunks on a car I always suggest using the key. I know it's kinda caveman tactics to use keys on cars with remotes but sometimes you gotta go back to the basics when technology fails.

Yep,

When all else fails, ride a bicycle LOL.... (nothing to worry about, key, battery, belts, alternator, cooling system, LCM, struts, shocks, oil, clutch, insurance etc.)

here is what i did

i disconnected the battery as i was working on the car doors (which has airbags)
i then by accident closed the boot and for some reason i coudlnt open it with the key.

what i did was

1) took back seat out (yes the other doors were open)
2) made small slit with utility knife in fat red power cable...
2) connected this to another car battery,
3) used door catch as ground...

4) pressed remote to open boot.

problem solved

Exactly. Turning the key 45° will activate the electrical unlocking, fully 90° will unlock it. If it doesn't work one way, try the other way. You'll need a real key, not a valet key. Again, the owner's manual will be able to tell you which key you have.

You can not be serious.

There is a jump point under the hood, you could connect a quick jumper to which will give you power to the car. locks and remote will work.

I don't think so if the Negative cable is not hooked up to the battery.

Just stick the key in the keyhole in the trunk and turn... Anton, you gotta be kidding!

Instructions from the owners manual that's been posted many times on how to unlock the car when there's an electrical failure:

1. As others have previously mentioned...the door & trunk lock cylinders were designed to be opened manually by inserting the key and turning it COUNTER CLOCKWISE (to the left)...PAST the normal position that electrically unlocks the door or trunk.

2. You can use the jump start locations under the hood (if the doors aren't locked) to open the trunk...ONLY...if you have the trunk lock in the unsecured vertical position ( | )....if the trunk lock is turned to the SECURED horizontal ( -- )...then you're stuck because only another MASTER key will be able to unlock the trunk (that's any of the keys you have that don't have the GRAY head...that's the valet/service key which doesn't unlock the trunk or glovebox). The trunk release button and the central lock/unlock button will not open the trunk if it is in the secured position.

We need more opinions.

Easy:
1) Smash small rear triangle window on passenger side
2)Realize that you are too big to fit
3)Smash regular rear side window on passenger side
4)Realize that though you can fit now, the trunk release button is on driver side
5)Smash driver side rear window
6)Realize you cannot reach the front seat from the back seat
7)Smash driver side window
8)Reach down and press release button
9)Realize button is electrical and does not work
10) Smash passenger side window
11)Crawl through and open glove box
12) RTFM

This thread is funny because I ran into the same problem and had to just keep playing with things until I turned the key past the point I thought it should stop and it unlocked the trunk.

I lube and exercise the manual lock/unlock on the doors and trunk each time I change the oil. The manual feature is so seldom used that it may become very stiff when you need it.

There can always be a better way to open a trunk. We are still exploring the complex problem.

Can you please be more supporting?

Between this and the thread on E36 forum about how to open the hood, I am not sure which takes the cake!!! Everyone must have eaten one too many "stupid sandwiches" lately.

If your battery is dead, cut a hole through the trunk lid with a reciprocating saw. I've done that twice now. Works great!

It would help the OP more if you please post a DIY.

PS. Congrats on opening page #2

A crow bar solves most problems in the car hehe...

Do you need help?

Buy a Touring. Problem solved.

Working on a DIY. It's raining outside and I kept getting shocked while trying to cut my way in.
