So I'm replacing the oil engine hoses and drive belt. My dad and I disconnected the battery and closed the trunk 😅 today we wanted to reconnect the battery but could not open up the trunk because no power. I used the key from the fob on the trunk but still it didn't open. I watched this video, I was able to pop the trunk by opening the middle of the back seat. The latch for the trunk to pull was wayyyy too far for me to reach and I don't fit through the small space in the middle soooo I used a longggg flat head and was able to push the latch for the back seat to come down. I had to crawl to the trunk to reach the latch and boooom it opened. Thanks for the video. If anyone else has questions I can post a video of how I was able to open mine. I have a 2009 535i xdrive

Hello I have a 2008 BMW 5 series 535i. My battery was disconnected due to theft so I didn’t want anyone messing with it. If my battery is disconnect and I don’t have no key fob yet.. what is my best luck to do in order to open the trunk? Would the battery need to be on in order for me to use the actually key from the fob to open the trunk? Need help please. My seats in the back are made to not take off the seats. I’m just figuring out what’s my best luck to open the trunk in order to turn the battery one.. please help!!

If you’re not worried about anybody messing with your car then leave it unlocked to be certain. But the car can be energized the way I showed in the video without any battery in the trunk.

I pulled the battery out and left it in my trunk and left it in there to to get a new one in the morning, I’ve tried the cable option, but didn’t work cause battery is no longer connected. Now the backseat option I tried, but there’s this 3rd flap plastic flap in there that covers it avoiding me from getting into trunk. Can this be removed?

Yes, but even with battery out of vehicle jumping it externally should work with the lugs under the hood

@justiceforall007 Год назад

I have a parasitic drain, and i jumped my BMW from the front to be able to open the trunk; however, i cannot open it with the key, only the button near the driver's door. Does this mean the lock/switch is bad or stuck and could that cause my battery to drain overnight? Also, not only does the key not work to open the trunk but the buttons on the trunk don't work either.

@Motorcarnut Год назад

If you can open the trunk with at least one button I would think the latch electronics are fine but could be the control module and if its bad can cause a parasitic draw.

@user-ov3pb3wg5w Год назад

I question if the "jump start" method (using the positive/red terminal under the hood combined with a ground) will work if there is no battery in the car. I believe the BMW's electrical system requires a battery to be installed in order to complete the circuit which energizes the accessories. I am not saying the battery must have any juice....just that it be hooked up so that when you employ the jump start technique the circuit is completed/closed and the trunk opener will work. By my theory, you also can not jump start a BMW is there is not a battery installed/properly connected. I base my theory on recent practical experience....my 2007 Z4M battery would not hold a charge/five years old.....I remove and close trunk.....go purchase new battery....come home ready to install.....opps. Trunk is locked and no key hole. I raise the hood and hook up jump starter box....I knew I was in trouble when the interior lights did not come on! My car is a coupe so I was eventually able to actuate the manual release "rip cord" to open the trunk. If I had not been able to do that......I would not be writing this post; I would still be trying to figure out how to open the trunk. Lesson learned: don't fully close trunk after removing battery.

@Motorcarnut Год назад

I never had a problem with opening the trunk with no battery using the front lugs. Although I never tried it on vehicles lower than 2011.

If you had jumper cables you can open the trunk by hooking up to the 2 positive and negative lugs in the engine compartment.

The boot will not open if you try to jump start without a battery inside nor will any electronics come on. Bit of misinformation there.

Information is accurate or it wouldn’t be on my channel. Either your car has problems or you’re not paying attention

@@Motorcarnut hey, yep apologies seems I misunderstood. Yes, your right you can start it 👍. The issue I had was my jump starter doesn't have an override button. So had to buy a new one and it worked. Thanks for your video, much appreciated. Liked and Subscribed 👍

My wife has a 2015 bmw x1 XDRIVE 28i, in my opinion it's a complete pos...constantly needs repairs I'm sick of it. All but the driver door will open and shut correctly. If you open the other doors they will not shut, then you have to spend time smacking the door around the actuators with a ball peen hammer to get them to finally close. Now the trunk won't open, the car has a brand new battery and positive cable due to it failing a few months after getting it form the dealer. The key fob won't charge at all when put in the ignition during the drive cycles. She can't unlock or lock the car with the fob, or start it without putting the fob in the slot. Idk what else to do at this point. She's still making payments on it, and it's a pain to put our child in the car seat when you can't open 3 or the 4 doors. We have to roll the window down, and buckle her in that way.

Well definitely sounds like electrical problems to me, and probably from the battery and cable change. All the codes in the entire car should be cleared then re scanned and see what comes up then. Because anything that is not working should set a code so it can be diagnosed from there.
