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... :dunno:

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.

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.here is what i did

Actually my 2000 BMW 528I have no KEY hole to unlock so one must hire a mechanic to get in through the backseat which I found the middle part which has a hole but not being a mechanic I'm don't know how to open it. NOT all BMW's especially the older ones have a key hole one flaw you apparently didn't know 'bout so everything in the truck including my mailbox keys are locked away taking seven months to get new keys from USPS from Honolulu made.

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.

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

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.
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.

Working on a DIY. It's raining outside and I kept getting shocked while trying to cut my way in.
i'm wondering if you remove the switch at the foot pedal and give it a 12v jolt, will that trigger the lock to open?
Hi All,
Im new here .. and i've seen your thread which once happened to me.
But the thing is My car is 525i and when it happened to me i simply connected a battery to the Jump Start bolt that is in the engine..This One:

and by doing so .. the car electricity was back, and i simply opened the trunk
i tried to search the google for the 540 jump start point in the engine but i couldnt find it :dunno:
if you know where it is, just connect the positive side to the bolt and the negative to any place at the body that is connected to the chasis and i guess you'll have electricity back in the car..
by doing that you can simply open your trunk!

FYI..did you know that if you lock the trunk manually you cant use the key remote nor the button inside the car to open the boot..its for time like valet parking so they cant steal your stuff.. (similar to the glove box) for when you give them the valet key.. I found out when I thought my boot latch was broken when infact my dad randomly recided to lock my boot with the key.. just a little something people might not have realised
