In this video, I show you how I unlock my BMW m3 trunk that I accidentally closed while the battery was disconnected. Usually, the key fob would be able to do this but not when the battery isn't connected. This video is for entertainment purposes only. If you are having issues with your vehicle please consult a mechanic or your dealer.
Thank you! My trunk was locked, battery dead and My seats don’t go down on my 2014 3 series so I had to jumpstart. I was connected properly but wasnt holding down the boost button to trigger power. You saved me from being stranded! 🙏🏽
Glad I could help! Subscribe if you don’t mind!
I’m doing the same thing and ran out of daylight and realized that if I close the trunk I’m screwed so I’m putting everything away and reconnecting the battery so I can open the trunk…a big mistake by BMW to not have a fail safe even though your idea does work!! People can panic in this situation!! Thanks for the video!!!
I don’t even have a BMW , I just love watching your videos lol. So informative
Thank you chica I appreciate the comment! 🙏🏾
Thank you bro, was connecting my subs with battery disconnected and closed the trunk on accident.
Life saver 🎉
Burgess - you are the man! This gas been driving me crazy and I was ready to get the z4 towed. I can’t tell you how much I appreciate your video!!!!
You’re welcome glad I could help
Okay now Mr. Willis! I called BMW and they confirmed that this works lol.
@@officialdevanee8155 for real 😮
Thank you thank you! Son disconnected the battery and accidentally shut the trunk. Thought he was SOL until watching this video
Few years late but, currently sitting in my wife's driveway late for a meeting cause I've done the exact same thing🤣🤣thank you bro your a legend might make it to my meeting now
Glad I could help 🙂
The tip with the red button just saved us. THANK YOU!
@@willfoster2712 yea sometimes it won’t automatically turn on
You saved my life i used the same jump starter as you on my 420i f32 that i had my battery disconnected in the back and after forcing it made a spark and managed to click on the trunk button to open.
Glad I could help mate
Thanks bro,I'm in South Africa,I accidentally closed the trunk after removing the battery,I didn't use the device you used.but I used the battery I removed and it worked.
Glad I could help! Greetings from the USA and Jamaica
Awesome idea nkosinathi... Avi here in durban... Same story
Clutch move I just finished up installing my pulley kit,
Belt and alternator on my e90 and this saved me thank you
You're a legend mate. Just locked mine out and this got it back open again.

Ayo I took my battery out and closed the trunk like a idiot on my 328ix will this device actually work? Please let me know
@@YoungMark318 did you ever get your trunk open? i took my battery out and the trunk closed.
@@jimmyzinter3822 nah, I towed it to the dealer and they did everything
You are the best !!! I was told to take apart the back seats, and belts to get in the trunk !!!! The little charger does the job !!!!! Thank you, Man👍👍🍾!!!!!!
Glad I could help !!!
Saved my life at auto zone took my battery for a check and charge and I closed the damn hood like a idiot thanks homie much love
Mr Willis, thank you! quoted >$330 to open locked boot and replace battery. your video negated this. i very much appreciate you taking the time to upload this content with the intent to assist others. thank you again, all the best
I’m glad I could help. Please consider subscribing to the channel it would mean alot
i’ve been searching for a genuine tutorial for so long, thank you so much this finally helped me
Thanks your video saved my day by showing the way to opening the trunk of my 1995 E38. Had already tried with a battery charger attached, but apparently that did not provide enough Amps. Inspired by your video I tried again with jumper cables and a battery - and it worked wonderfully. And this E38 has no other obvious alternative trunk opening options.
Glad I could help!!!
Thanks a lot. I have an 18 M2 and did the same thing. Your video is the only one that showed exactly what to do.
Glad I could help man!
Thanks it works on a 325i and I did it myself thanks to your instructions.
Thanks a lot.
You’re very welcome. I’m glad I could help!😌 Please like and subscribe to the channel for more content 🙂
A Life saver. This is the a much better solution than trying to get through the back seat that most other videos show. Thanks !!
can you do dis using a battery without genius booster
Had this prob 2day. Disnt have a booster so called recovery. Guy didnt have a clue so I showed him your video. He wired me up.... boom. Even he was chuffed to learn this trick. Nice one.
Ahhh man that’s awesome! Thanks for watching glad I could help
Thank you so much. My battery in my 328i convertible went dead with the top open...haha...you showed where the connector for recharging the battery was under the hood and save the day. ❤❤

Appreciate it bro my 650 batter died on me , This Really Helped!
Glad I could help man! Please consider subscribing to the channel 😌
What a great and helpful video. I stored my X6, disconnect the battery, left the bottom floor hatch that covers the battery and lower storage stuck in the open position and is locked up against the closed tailgate. And because of this I’m unable to access the emergency latch. Called numerous BMW service centers in California and got no answers. Will definitely this and crossing my fingers it will work. Thank you!
You’re very welcome! Keep me posted on how it works out. And if you love the content please consider subscribing to the channel 🙂
Thanks man, very helpful - thought I was going to find out how to tear the car apart.
Thank you for your video !!!!!!! 🎉🎉 I opened my car 👍🏽👍🏽
Lmao when you said “genuine boost” I died🤣 but Thank youu🫶🏼🫶🏼
Yo thanks a lot for this video man really helped unlike all the other videos
I realize this thread as hell or old but it's still relevant to this day my question is when using that function on that jump box because I have the same brand that gets rid of some of the failsafe and will it still be okay to I fear that the footwell device that operates all the lights and things like that will it damage that
Did you have the (+) still connected? I disconnected both to change the battery and closed the truck; do you think this would work if both were disconnected? Thanks in advance!
Bro I'm thinking about buying one of these today and trying, I've connected jumper cables and it didn't work. But apparently it has to give enough amps for it to open. I see that they sell them for like 100 to 150 bucks. My battery is fully disconnected and taking out the car it started to rain so I closed the trunk. So if this works I'll go ahead and send you a link to the exact model he's using
Thank you so much super helpful. Super easy to watch. Saved my bacon. Thank you.
Worked first time, excellent video thank you 👍🏻
You absolute life and money saver. Thank you!!
Thanks heaps…you got us in from Aus!! Good job
"Handy dandy". Interior light was on at the beginning. Wish my stupid car would do that with an unhooked battery. Or just carefully planned editing afterwards making sure the jump box idea had worked. Pretty sweet.
In the begining of the video I’m in my Prius that’s why the light is on lol.
Thanks, brother- hopefully it’s going to work out tonight- fingers crossed
Can you also connect it to another car to do this or do you have to use thay same device with an override button. I am trying to use a jump starter pack but it doesnt work. The one i have doesnt have an override button.
You are a Life saver, browsky
Thank you so much 😊 you helped me open my trunk 🥰
You’re welcome!!! Glad I could help
Would this work with a engine starter ?
I tried it and I'm still locked out....2015 659i conv
Saved my life thanks 🤘🏽
Great video! Just wanna ask that does it work for Cadillac ATS as well? Will there be a spark in the trunk when I try to jump start it at the front?
sg beat I’ve personally been locked out of an ats before and I personally used the same steps as in my video and was successful.
Burgess Willis thank you for your help🙏
@@connorgao8007 no problem glad I could help
I’m currently going through the same problem with my bmw ! But it’s not working, should I try using a more higher source of power such as my home boy truck via using power cables to send high currents into the car
Did you try using a power pack like what was used in the video?
@@burg2daworld my dad & brother have a halo booster! But it’s not the one you have in you video that has a button to amplify the power, im going to buy the booster you have though at Walmart
Does this still work if the battery is completely disconnected positive and negative?
Thanks Burgess. It worked perfectly.
I’m very glad to hear that!😌
For real 😮
I have 320i 2018 i disconnect my Bettary it gonna work ?
My battery is disconnected and glad I found this.I had a towel over the latch but someone removed it and closed my BMW hatch. I am working on the engine. My question is will fuel spit out of the car with this method of boosting the power in the front as I have the fuel rail off right now?
As long as you don’t attempt to start the car the fuel pump “usually” wouldnt just turn on like that. Also, please subscribe for future videos of similar topics🙂
Will this work even if my car battery is running low and car is starting but my 2017 m240 still won’t open I can hear it click but it won’t open
Will this help with 07 328i?
I disconnected the whole battery and connected jump leads to my friends car, should this of worked? Or do i need a battery pack like this🤦♂️
Finally 👍👍👍
Do yk if it works on a bmw 328i 2011?
I got a question how to fold down the rear seats from inside the car ,not from the trunk ?why wouldn’t they make a leaver or something to be able to pull down a seat from the inside 🤦🏻♀️I tried to figure it out but I guess no way :(
thank you so much your video saved us!!!!!
Yes Sir...thumbs up!
I had that issue, on my Escape, even if you can get the door handle with wire, it will not open door, finally, I used a long thick wire, bought an inflatable shim air bag for $18 at Home Depot, inserted between door from top of door, and reached the hood release, took about 20 minutes but was able to pop the hood, and then jump the battery for a minute, and then I could use the metal key or press unlock from key fob.
David sounds like it was a pain😬. Glad you got it in tho!
Hey how is it going
I want to make a hole but do you know anything else I could do ?
A hole where? In the door?
Hey bro can i do the same by applying jumper cables just so it has current to open the trunk, i closed it after taking the battery out.
Daniel I’ve had to that before and had success by doing it that way. Actually in the manual it states that another car can be used to jumpstart the battery. Hope this helps.
What brand is the charger ?
Great video. I am in the exact same spot, except my bmw doesn't get any power when I hook up jumper cables. I am still locked out of my trunk. I'm thinking maybe I blew a fuse? Any help is appreciated, thanks in advance
Sorry to hear that I hope you where able to fix the issue without too much cost.
What if I lost my key fob? I got a locksmith to open the car and I’m sitting in here but the trunk button won’t work inside the car. I think the keys are in the trunk
Smart man appreciate you I was in the same situation 💪🏽🙏🏽
No problem anytime
Oh man... Thank you so much for this bro
No problem . Consider subscribing to the channel and tune in for more content 🙂
Thank you. It worked perfectly.
thank you this helped.
Thank you sir! Very helpful!
No problem glad I could help!
I have a bmw 1m with the battery out , i tried connecting a battery to the front and couldn't open the trunk , but i didnt have the booster as the one you have on the video. Are you telling me that it will work even if i have the battery out , not connected?
In many cases I have seen success without the battery being in the car. Let me know how it worked out.
@@burg2daworld Nothing worked as you have to have a closed loop with the battery. Only thing that worked was a camera rod from Home Depot with a hook at the end, fish it in between the seats and pull the handle.
@@burg2daworld Im surprised it works for other BMWs but not mine.
@@dee1251 wow man I’ve never ran into any bmw where this procedure didn’t work. There’s a first for everything
@@burg2daworld i did it this way last year, did it again yesterday no dice . It’s because this time I disconnected the two thick red wires from the battery terminal in order to get the battery out I think and that broke the circuit on the hot side
great video very informative
Thank you Nayanne I’m glad I could help!🤟🏾😊
Hey Burgess it's me sophia 🙂
😁
This doesn't exactly explain if the battery is disconnected
Yes the battery was disconnected
Hey man I’m in this exact situation. Problem is my key won’t work no matter how I try it in the door. I have no access at all to the car can you help please? Any link or advice ❤️
The metal key 🔑 won’t open the door?
E60(08 528i) no battery in trunk,connected cables to underhood & still couldn't pop it..ugh
I have a 2006 and experiencing the same issue, sad thing is both of the keys don’t even work. Cannot open the trunk. There is no access to the trunk through the backseat. I’ll give this a try.
Let me know how it works out for you. Please consider subscribing to the channel🙂
I got the NOCO GB50 but it says I shouldn’t try jump start anything that isn’t a lead acid battery my Bmw m4 is Lithium ion. What do I do bro?
Gurpz Experiments from my experience with the f80 the battery pack hasn’t been an issue for the fact that our cars have a IBS intelligent battery sensor that aids in keeping the battery safe. It states right in the manual that we are able to apply 12 volts to the positive which in a way will “wake the lithium battery up” if it has fallen below a certain level.
Burgess Willis my battery has been dead for about 3 months now. I’ve put the NOCO GB50 on charge shall I just go for it? I don’t want to risk blowing anything or messing anything up.
Gurpz Experiments 3months? That’s a LONG time to have a lithium battery sitting there. Tbh you might have reached a level of low voltage where the battery itself is at the point of no return. If that was me I would check the voltage at the negative and positive points of the battery . Then if it has power I would apply the bmw lithium slow charge from ctek and let it charge that way.
Burgess Willis that’s what I done, but the ctek XS keeps coming up with an error code. I pressed the the reset button to try bypass the UVP but it didn’t work it wasn’t powerful enough?
Gurpz Experiments another way I have been successful in “waking up” the lithium ion battery in the past if the charger wasn’t successful..is to apply a jumper pack directly to the lithium battery for a few seconds so that the “breakers” In the battery itself will detect voltage and begin to take a charge. Once that was successful I proceeded to finish the charge with the ctek
I bought this exact one after this video for my bmw f10 5 series and this does not work on my car
Tried it and it didn't work on my 2011 F10. Maan I am sooo screwed! Even tried it with the jumper pack you have with the override. No luck.
That was great, thanks for the tip
thanks bro 😅
Anytime!
I plugged in a noco battery charger and it’s been like hours and still dead battery :( I was hoping I can recharge it with battery charger not a jump start 😢
2010 128i convertible, it didn’t work.
Ok so I'm in this SAME SPOT, I tried using jumper cables an it's STILL not responding, I don't see how that device is different then using actual jumper cables. But I'm gunna take your word for it my man. I'll be buying one of these
The question is how you open the trunk without jump ?
does someone know if u can open it from the inside instead of the controller
How much does the portable jump box cost?
You should be able to find one for abour $125. Atleast that’s what I paid for mine. It’s a good investment in my opinion. Please consider subscribing to the channel 🤗
It doesn’t matter if you battery is unplugged. Connect the jumper cables to the positive connection under the hood and ground the negative, and you’ll immediately get power to pop your trunk
What if both positive and negative aren’t connected? Lol
@@johnsondoeboy2772 I would try connecting the jumper cables to the front battery connections. I still think that it will give you enough power to pop the trunk. That said, I’m no engineer and know that it worked for me despite having the negative cable disconnected from the battery in the trunk. Good luck
@@algomez6629 My negative was only connected, and my trunk is opened thankfully. The creator of the video just recently said that even if the battery wasn't in the car, it would still work.
Good I do the same I’m going to try that
Thank you God bless you
what to do when that is not an option ?
You da man !
Thank you Gary I’m glad I could help🙏🏾
Dam bro I was having a panic attack thinking their was gonna be no way
My key wont open my door. I thought the same thing but NOPE! Wont freaking open 😂 idk what i am going to do. Maybe break a small window 😳 😬
Awesome, thanks
Just used it just now. BMW M6 it save me!!!
Glad I could help!!!
U save me 😂 thanks i almost 😢
Thank you!!!!!!!
No it doesnt work with bmw 520 d bcz there is some another Wire which is Mounted on Top of + Sign ,then afterwards car will get power
You da man
I tried this on my wifes 328i hooked up to my 19 titan with number 6 jumper cables. Car got no juice what so ever
Did you use this model with the button that sends power through the system? This model works because when you hook it up you have the option to send power through.
