That would be very appreciated to help me solution for my problem I got so far. (I have tried searching all threads relevant but I couldnt.)
I left my car for 3 months at the parking and found battery is completely dead or there was no indication on OBD when ignition turned on!!. What is worse was central locking could not be disactivated and couldnt access to battery location in the rear trunk because rear is still firmly locked even though battery hasnt responded anything!! no electricity came on.
I also tried jump starting but so far failed providing enough power (current) to neither motor nor central locking module....
I have already tried jump start cable locating the position in the engine room at passenger side. But unfortunately, it seemed already unhealthy dead battery though. For rear trunk, I had an immediate few attempt by putting the key in unlocked direction plus pushing the button for opening. BUT Still rear trunk were stuck and didnt let me open strangely. So I thought this seemed derived from central locking. (I might be wrong..)
Could anybody advise me to sort out opening rear trunk at least and give me direction how I can power on my E36 engine please??
What I dont understand for this problem is that I couldnt see any indication on OBD even though I connected jumper cable to other cars while boosting,,, Does that mean any electric immobilser management control was activated or smth??
I second that... my first guess would have been to bypass the central locking and use the key; but looks like you tried that (you'd be surprised how many people think you can't open a trunk without the key). So, see if you can fold down your seats and access it that way. If they don't fold, there's also a way to remove them entirely (temporarily, of course),
im sure the rear key lock should open it without the central locking system being active, matter of fact i think every door can. in any case, you do have a sedan so no fold downs, ive never actually attempted to remove the intire rear seat assembly on a sedan so maybe someone can walk you through it. or another idea you could try (what i would do) is pop the hood and see if a trickle charger will help you out (always good to have handy for times when you .............well store the car for more than a month hahaha) give it some time to charge than you should be good to go unless you have another overlaying issue.
I still don't understand why when he puts the key in the lock of the trunk and open it... this is really bugging me.
I do not think that the problem with your trunk has anything to do with your central locking. Here's why I think that. When I first got my car the battery was completely trash, I had to use a jump start pack to get the car to turn on but drove it and it seemed to hold a charge. Then I left the car alone for a few days and came back and the battery was dead. If when the battery is dead how is it that I could open the trunk and get to the battery to replace if it require electricity to open the trunk even while using the key?
Perhaps you are using the wrong key? If it's not a master key it will not open the trunk. Or perhaps the trunk lock is stuck.
^^^ agreed. Make sure you got the real deal - the smaller valet key will only open doors. As a privacy feature, it will not open the trunk... Good call!

First of all, many thanks all guys for all of your comments in this thread, really appreciated!
Then, I noticed two things after reading several postings here.
1) That was completely same situation as you had previously like I quote above. When I first got my car the battery was completely trash, I had to use a jump start pack to get the car to turn on but drove it and it seemed to hold a charge. Then I left the car alone for a few days and came back and the battery was dead. If when the battery is dead how is it that I could open the trunk and get to the battery to replace if it require electricity to open the trunk even while using the key?
So, probably I could think some of gentleman be able to help me hopefully. Still I cannot provide sufficient amperes to electrically unlock the vehicle.
2) None of keys (including master key) could not deal to unlock the rear trunk today sadly. I got 3 keys with me and carefully tried all keys but unsuccessful. According to service manual, E36 is supposed to have 4 keys but not 3. Would you think it came out to be problem in the end??
For the time being, I pruchased a new battery (55AH 600cca) for the sake of central unlocking deactivation. I am now really hoping to make true of it finally....
With the "double lock" engaged you cannot unlock the trunk with an outside key. You must open one of the front doors that then unlocks the trunk. SInce you have no power to do this the trunk stays in "double lock". The most locigal solution is to get the car power. THe jump start method will work. You must keep the jumper car connected for a while tho (10 minutes, 20 minutes.. whatever it takes). At certain intervals I would try to lock & unlock the doors untill there is enough power for the double lock to disengage. Most people assume that right away the car is jumped and good to go, but in extreme instances where the car is left for months you will need to keep em connected a while to build up enough juice..
Also i saw someone mention sedans dont have fold-down rear seats.. yes they do. Mine has got them..

Woops, didnt know anything about "double lock" stuff, really thanks your comments!! Then, please allow me to ask stupid questions. Do I have to keep idle condition for jumper car when I connect to my car? As I am living in Germany, I am not allowed to keep ignition at standstill for longer minutes by low. If sufficiently ok without ignition, I will try tomorrow.
yes, the jumper car should be at idle when connected- actually reving the jumper car should charge faster. You wouldnt need as much juice as you would to start it. You need just enough for the locks to work (i wouldnt even try to start it as it will waste power).. intermitently try to lock/unlock the drivers door. As soon as the other locks respond to the drivers lock you should then be able to disengage the double lock and get into the trunk.
Once you get enough power: close driver's door, lock and then unlock (all four door locks should then unlock). Now the trunk should be unlocked as well..
YAHOO!! HAPPY NEW YEAR!!
In the late yesterday evening at Eve, FINALLY, I managed to unlock my central locking at the both doors and rear trunk by boosting as recommended here!! THANK to all of my mates and I made it turning my 6 cyl motor ever since 3 months soon after battery replacement as well. Good ever news for 2006!! really feeling excited with firework celebration all through the town here! So many straggling stuffs I have experienced for that to tell you but anyway next time,,
Now, I start to think what I will upgrade my 320i this year in 2006, hehehe. Give me any suggestions and inputs please.
Happy 2006 to you!!
