This is the first comment I've left on a mechanical TH-cam video. You saved my butt, thank you so much for this information I would have been completely dead in the water
No problem! Appreciate the feedback, glad it helped!
Tried all three.... external battery worked..
Thanks
Glad it helped, thanks for the comment!
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
Great that it helped! Thanks for the comment. Appreciated
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!!
Thanks so much for the video! BMW's are a pain in the butt.
Hey, no problem glad to help!
Bruuuhhhhhh you just saved me!!! I couldn't get in my car for nothing. Tried to find so many videos and nothing then late at night this video popped up ...MY LORD! thanks bro!!!
No problem 👍 glad it helped. Thank you for the feedback I needed that!
This really helped. My trunk was locked out for 3 weeks and I just opened it. Thanks to this video
Glad it helped and thanks for the feedback!
All I got to say is it’s a good thing I’m not fat. This was almost a big problem.
I was going a way for quite a while so wanted to disconnect the battery. Did and shut the trunk. Then locked driver door with key blade. Realized the other 3 doors were open! Now I gotta reconnect the battery. Hmm. Can't open trunk. Plane leaving soon...
This video. Success !!!
PS. Nobody else in garage as I probably looked quite weird crawling out of my trunk lol
Awesome glad it helped! Thanks for the feedback.
Without power u won't have central locking. U will need to lock doors individually. Pull on outer door lock and press down lock button on the door inside that locks the car then close the door.
Thank you so much. i have successfully opened my trunk because of you!
Great to hear! and thank you for the feedback!!!
Thanks man 👍
No problem, thanks for the comment
Yes! Worked pulling the lever on my 2009 BMW series1 coupe thanks
Glad it helped
Thank you for sharing....it works with external battery...😊😊😊
Yes it does, thanks for commenting
The cable tricks worked well. Thank you
You're welcome!
Thank you! Now i can try to change my battery that's stuck in 3 inches of ice💪
Glad I could help! Good luck!
Informative video, thanks mate.
No problem 👍
I love your beach cruiser. Bro.
Thanks! 😃
Thank you, the jump worked!!
You're welcome!
Holy crap I didn’t know the key was IN the fab THANK YOU
Lol, No problem!
Thank youuuu
Sure, no problem
good video thanks
You're welcome!
Tnx bro
No problem!
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
Thanks
No problem
My E82 doesn’t have a key fob for the trunk and the battery is shot. I just have like a regular booster, nothing that big but not one that only mantains the power, I think you get what I mean.
Do you think the booster will work in the front just so that I can open the trunk to charge the battery? Or do I really need another battery/car to make it work?
Thank you!
You can try it? If not you will need a battery or charger
@@Motorcarnut I'm trying it in a few hours. I was just a bit concerned it could short the booster or something like that, I'm a bit scared when it comes to eletric stuff 😂
I'll leave a comment here afterwards, might help someone.
Definitely Thanks
@@Motorcarnut well it didn't work. The booster didn't let me choose the "12V AGM/Gel)" option because it would only recognize it as a 6V battery (it was reading 5V from my battery).
I'll try with jump-starting it with a running car.
I have an 07 328i that has a flat battery i need to replace. Do you recommend me leaving the car unlocked after removing the bad battery ? I want the same battery specs but not sure I’ll get it done the same day if they don’t have the specific battery I need… I’m scared ill lock myself out by locking up the car after removing the battery.
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.
The 07's usually have a key chamber to unlock the trunk. Right side to trunk pull.
can I use a battery charger instead of a jump starter ? thanks
Absolutely
Thank you saved my ass
No problem!
My girlfriend's 2019 330i xdrive didn't have a key insert in the rear. Had to squeeze between back seat to pull that lever. How dumb of a design for an overpriced non M car.
The 2 other methods should of worked?
There's no key hole on the outside trunk. Car was parked on a one lane driveway so couldn't get a car to jump the front. Plus don't have a portable jumper. They could had just kept the trunk mechanical instead of electrical. What were they thinking especially battery is in the rear.
@@bliatayhaving the same problem😑
How did u do it
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.
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.
The third options sounds a good alternative , but be very careful . I did it exactly the same way and my FRM was damaged .
Sorry to hear that but something must of been wrong with your electrical system because I jump vehicles all the time that way. This information is from BMW as well.
Any idea how to open the trunk of a 6 series F13 with not battery and no fuses installed?
No
Thank you bro 😎 open up my trunk 👍🏽👍🏽👍🏽
Glad to help! Thanks for the feedback!
The manual key that clicks out the fob is how I got in my 2010 bmw 750 li
Yep, that’s one of the ways
We have a 2011 328i. There’s no trunk key hole, no rear seat access, and we tried using jumper cables on the spots you suggested. Nothing happened. Any suggestions about what could be wrong? I’m desperate. :(
Is the battery in the trunk disconnected or not there at all?
@@Motorcarnut Thanks for replying! :)
My husband was able to use a battery and paperclips and go under the glovebox to open the trunk. There had been no battery bc we took it to get it checked. So now it’s back in. But now the car won’t start. :( It sounds like it’s trying to, but can’t get fully going. Any thoughts or suggestions? I really don’t want to have to get it towed to a shop if I can help it…
@christineladner965 Any codes ?
Hi..if there is no battery in the car..as I wrongly closed the truck after unplug the battery
You can still you these methods
What could be the reason the manual key won't open the door?
Try spraying some penetrating oil in key slot and wiggle it side to side. Can be from not using key.
@@Motorcarnut thank you. Turns out I wasn't applying enough pressure whilst turning the key. I finally managed to get it opened.
@TheNinjaDuchess great! Thanks for the reply!
We have a 2011 550i. Key fob battery is good but valet key, held inside, broke in the past & I cannot locate it. Car is locked. Car battery needs a jump to run.
Any ideas on what I can do??
I’m not sure what’s going on? You need a factory main key fob for the car to start. If the battery needs a jump to start it should be replaced first. These cars rely heavily on a good strong battery.
@@Motorcarnut thanks for the reply) The car battery is fairly new but it’s been parked for a while.
No worries. I’m calling a locksmith 2moro. Thanks again.
@kristymarshall no problem, good luck
I have a 2010 328i and had the battery in my truck when the grandkid slammed the trunk on the BMW. With no battery hooked up the jumper cable method does not work.
Then there is something wrong with the battery wiring that connects to the positive side.
The trunk button doesn’t work 2010 bmw 328i. Can’t find the fuse for it to see if fuse is out
Does it work from the remote or the button inside the car?
Can I start bmw 528i without the key fob
No
Hello, what can I do if I just disconnect the ground cable from the battery in the trunk and it closes, can I still do the last procedure with another battery and jumper cables? Because the red cable is still connected to the battery in the trunk that why my concern can u confirm o somebody help me please
Yes, you can jump from engine compartment on lugs shown in this video
And what happens if i use jumper cables car by car is dangerous?
@luiscarlosmontanosaenz7717 no just don’t mix up cables + to + and - to -
my car starts and still won't open. I popped it open with the trunk pull but it won't open after shutting again. any idea????
Electrical problem I suppose?
2011 328i battery isn’t in the trunk I closed it as I went to get a replacement, I don’t have a hole to squeeze through, no key hole in the back, and jumping doesn’t help. I’m out of options and extremely frustrated would love to hear some advice
What about jumping the lugs under the hood? Doesn’t need battery hooked up
I have the same car and I just bought a new battery while I’m locked out so hopefully I can do this method with the new battery?
@reezyc23 yes you can
It didn’t work for me :/
You tried all three? And even if the old battery is not in the trunk as long as you didn’t take the terminals apart and jump the car from the engine compartment it should work
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.
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.
I also found an ingenious solution. Don’t ever buy a BMW. 😂😂😂
Lol, their good vehicles but just like any other manufacturer they have their own problems as well.
What if pyro fuse is blown? Jump start won’t work
Probably not
I tried with jump starter with no car battery did not work at all:/
If you took apart the electronics that connect to the battery it will not work. But if you just disconnected the battery for removal it should work.
@@Motorcarnut oh shit I will have to crawl in there to connect the battery😩 well will be fun I never changed done it before
What if you locked the jumper cables in yhe trunk
Get a new pair
2 wires and a Dewalt 20v battery
well last one dsnt work for me. my battery is out. i connect it in front and nothing happens :(
If you disconnected any fuses or connections that go to the battery cable it won’t work if you didn’t then there is something wrong with your vehicle
Skip to 3:50 for #3 thank me later
All 3 work, but if the 3rd one worked for you, great!
What if the battery is dead and the key doesnt pop the lock on the door?
Then you need a locksmith. Why wouldn’t the physical key open the door?
@@Motorcarnut that's what I figured cars been sitting for about year due to engine problems and finally got a chance to work on it when I tried to unlock it with the key it turns in the tumbler but doesn't do anything
My 2012 bmw battery died on me and i cant seem to be able to open the car,i have tried everything possible and i still cant get into the car
According to BMW these are the ways to get in the vehicle. I don’t know why you can’t?
@Motorcarnut My trunk and bonnet(hood) are both locked and my mechanical key is spoilt
All doors are also locked
Damn that's rough. If you could get into the car at all then you would have a shot but idk how you will get in like this.
They dropped a bmw6401. Convertible , off here in the yard. I know in my heart that it is a gift thank Gigi. But up against these fellas who lie an claim the vehicle I even goty li0 busted attempting to enable it. It's going to be a difficult situation for me to get this to the wrightfull recipient. And they need it badly. The 0ower was on when I opened the door. The radio and screen was in working order but a push-start with no fob uelp me get it going to come to their aid in a timely manner. I would be forever endeaded. Thanks. Kcb
Do you have the key for the car?
The rear seats method does not work on bmw e60 525i 2006
That's why I gave three ways to try
I do have the key, the truck have some issues I wasn't able to repair, so the truck literally sat for over a year. It couldn't move, now I am able to repair and now it is totally dead. The will go in and it will not bulge at all. The truck dead dead.
Just jump it from the power lugs under the hood, should open the trunk that way
Even the battery is not in trunk how can you open via jump start
The battery doesn’t even have to be in the vehicle when hooking up external power to open the vehicle
@@Motorcarnut I hope you are 100% correct because I've been locked out of my trunk for 2 days after putting in my starter breaking in a mission hose looks like a (Y)
I am going for the trunk please tell me that this will work without the battery being connected in the trunk I have the positive on but not the negative please let this be
Yes, just put a jumper on the positive terminal in the engine compartment and the neg to the neg terminal
He is absolutely correct I let mention .
I was replacing starter with the negative battery terminal disconnected
I was going crazy and I was about to pull the back seat then I stumble across the I was amazed to see that the man was telling 100% truth
Yes you can unlock your trunk from popping the hood and connecting at the jumping cable terminals under-the-hood to release your trunk even when it's disconnected
Lol, thank you! Of course I tell the truth.
Does anyone here know how to close it from the inside? The button works to open but not close ?
What are you trying to do exactly?
BMW X5
.
I tried the jump start method it didn’t work
This is not the jump start the engine, only to get into the trunk.
@@Motorcarnut This also doesn't work for me? e90: They broken in and stole the battery, connecting another battery via the front jump tabs did nothing, ie car still electrically dead. Advice?
Idk, it’s supposed to. Maybe they ripped something out when they broke in?
@@Motorcarnut spot on, turns out there are 2 red high current wires coming from the positive terminal joint under a red plate, if they become disconnected, ie the two red wire aren't electrically joint there is nothing to do via the jump tabs to open the boot/trunk, the only way left is to cut a hole behind the seat or inject 12V into the loom to unlock the solenoid.
Yep, that’ll do it.
I tried this and it did not work, still lock out
Then you probably have other issues.
Nothing works. I can not get the terminals to get any contact. I have tried everything. I will never buy another BMW. How stupid are they?
Not one of those works? You may have a short somewhere which is not common at all
I agree
Not even a battery in the truck... wtf no way yes way
Lol. Yes!
Eventually , I just changed the battery. #1 and 2 didnt work. I dont have a jumper cable for #3 lol, because it's in the trunk.
I just want to say that this was really2 shoddy engineering from bmw. It really makes it hard to do things with this car.
If you had jumper cables you can open the trunk by hooking up to the 2 positive and negative lugs in the engine compartment.
No, certainly on an F10 model none of these work. The simple and only answer is to remove the rear seat. Yank up the seat base and remove it. Then, unbolt the three bolts holding the seat rear in place. You can then access the battery.
One of those should work unless there is something more than the battery wrong with your vehicle. These tips are from BMW
Yeah none of these methods work on an e90 328i 2011 either
Then something else is going on with your car
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.
What if the car is totally dead you can not open at all.
What year and model do you have?
@@Motorcarnut 2008
What model?
@@Motorcarnut BMWx5
I believe that vehicle has an external key slot. You don’t have the key?
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 👍
Thank you! Very much appreciated! Glad you got it opened!
Well those didn't work 😕
Probably something wrong with your vehicle then
So much for German engineering, bmw is terrible to not have a way to open the truck with a key, makes zero sense.
More and more manufacturers don’t want owners fixing their own vehicles, that’s where I come in :-)
