- It's not what you think. NO it's not a jump starter. Ok it is. But it's this SUPER cool item you HAVE to buy that costs $3 but can save you a ton of headache!
This ONLY works with an UNLOCKED TESLA (Via APP) or a completely DEAD 12v battery.
You CANNOT open the FRUNK with a battery when the car is LOCKED!!!!

Just to clarify: This method works only if the car is unlocked (via the app) and the 12v is completely dead. It WILL work if the car is unlocked the 12v is alive and working but at that point you can just open your frunk through the screen. The FRUNK will NOT OPEN if the car is LOCKED with a healthy 12v battery using the battery method shown!
Get the battery here if you can't get into your Tesla!

Thanks for that important clarification
Now I’m confused, if the battery is dead. The car won’t unlock so this will never work?
the tesla knows when the car battery is dead so it will work! @@pj4433
The tesla knows when the 12v is dead so you can open the frunk! @@pj4433
Phew! I was worried that a thief with a small battery could open any Frunk they wanted to!
One thing to note: you should set a calendar event to periodically take your jump start battery inside to recharge. The last thing you want is for it to be dead the day you need it.
Good call!
how do you do that
Yep 😊
These batteries are lithium, I had a few instances where the booster battery is weak especially during the cold season. Some of them includes an auxiliary adaptor, so I kept my ICE car booster connected to the “cigarette” lighter adapter that turns on when the car is and charges the booster. I haven’t figure out what to do with myself Tesla yet since it should be in the frunk. For now, I have AAA coverage for both of our Tesla and ICE car since they are both out of the road service / warranty and both has the original battery. 4+ for Tesla and 9 years for our BMW.
I not a tesla driver, but I have a jump starter in my car, I charge it maybe once a year, they should hold charge for up to 3 years or more depending on the brand. you don't need it to be charging the battery all the time, it will reach the cycle life and will be dead when you need it the most. Its like charging your ev battery everyday, even when its full, eventually you will reach the end of life sooner than the original timeframe
Chris, I've watched your channel for a number of years now and this one just prompted me to check my battery which is over 14 volts and order the A23. Thanks again for this information.
Chris, you are a mountain of knowledge! I learn a ton from your videos all the time! 🤯
Awesome! Thank you!
You also need to tell your viewers that the jump starter needs to be kept charged by charging it every other month or so. More frequent in extreme heat or cold. And they should always keep sentry mode on to keep criminals from accessing your frunk.
Tesla should really make that option a type of physical key so that only the owner can open it.
Agree I don’t know why they don’t. Or maybe an rfid for the key card for it to auto open.
You sont have to worry about a thief breaking into your frunk even if you leave the battery in there. The frunk release only works if the 12V battery is dead or the car doors are unlocked.
I can confirm this is indeed true!
I don't know how this guy does it, but he is always smiling even describing boring materials. It's also contagious as I find myself smiling along. 😄
😀
This seems like a giant engineering failure on Tesla
Super useful vid. Thanks man!
ELECTROCUTED! LOL, I like your humor. Well thought out video, thanks
Recently received the notification on my Tesla and had mobile service come out to change the 12v battery. $118, tech was in and out in 10 min. I know many young folks in the comment section are disappointed the 12v can fail but before Tesla's software warning and mobile service, automakers for decades didn't give a $hit if you're 12v died. And no mobile service or fancy mobile app was available, you just just hoped and prayed you were near an auto shop that could help in an emergency. And if you drive any American automaker brand you know brands like Ford and Chevy always have a check engine light on new or old or the indicator for the 12v battery was always lit up, and since it was always on because of bad censors you just eventually ignored it until one day the 12v was in fact no good.
This is really useful information! It just beats by WHY Tesla makes jump starting so user-unfriendly as compared to a gas engine where the battery is easily accessible.
I assume because it’s much easier and cheaper for them to design a system like this with virtual keycards than to integrate the creation and distribution of physical locks and keys into their production line.
Here is an EV sidebar; my Kia Niro BEV has the 12 volt battery right out in the open, where it can be reached. The 'frunk ' is smaller than the Tesla. If Tesla had consumer sense in mind, it would be in the rear of the EV. And use the same panic open feature
I had the misfortune of a terrible head on accident with my Model 3 on the driver side due to a red light runner. I thought I was so prepared at the tow yard with my battery and jump starter, but the front was so mangled I could not even find those two leads. I kept the cover as a reminder, the leads got ripped off and lost somewhere. Cut up my hands looking for them.
The only way I got into the car was that since the windows were vented after the airbags went off I found a long piece of junk with an angled end to pull the emergency release from inside while bending the window back. I got the trunk open by hitting the 'kidnap button,' which was hard since the Highway Patrol filled up the interior of my car with the junk from the other one, also got all cut up from this...
To try and make a positive out of it if you do get into an accident open the glovebox and GRAB THE USB/SDCard whatever has your dashcam footage. In my case there was a fight over who was at fault, and if I could not get the USB that day it would have been a massive pain to then try and get the video evidence later.
Also please just because you have a green light does not mean it is safe...
Nice vid, but as an Electrical Engineer I strongly advise: always connect Mass (negative/black) FIRST. This is for safety.
Amen
I heard there was an always start 12 volt battery system for ICE cars so the 12v will never die have you tried to use that system in a Tesla ?
It is that plastic bag safe to store in that area? I mean, doesn't that area get warm/hot that could cause the plastic bag to melt and could potentially start a spark/fire?
Six months later but as a Tow truck driver, I tow more Tesla's than any other car. 90% of them all had this problem happen without warning.
Just happened to me. Luckily it died in my garage. No warning. Darn car locked itself and the little battery trick didn't work so I had to use another car battery just to unlock it. Drove to the Tesla service center in another car and replaced the 12V battery for $89.
This is great! Cant wait to go try this on other Teslas and see what goods they have!
Much appreciated ✨️ definitely more than a thumbs up 👍 👍👍👍👍👍👍
Great video. Thanks Chris!
You're welcome!
what about the 16v has anyone had this die? the 12v is to be expected because it old technology that is in every car you will be lucky to get 3 years out of it.
I must be lucky as my 12v on 2018 Model 3 lasted 4.5 years (65k miles) before getting a warning to replace it.
Always thanks to you Chris. You are my Tesla guy. I think Tesla should pay you for making educational video like this one.
The 12v battery is the Achilles' heel for Tesla. Imagine being a week long road trip and it dies. Not sure why the entire system can't be powered by the large battery pack.
I have not run across any real geeky technical information on Tesla's yet. Seems the real interest is driving it. Yes, why doesn't the car have a step down converter that can use the big battery to provide "some" power to the 12v system. An example is like an electric golf cart where you can get a converter to step the 48v battery pack down to 12v for an accessory, like a radio, lights, etc. How can Tesla be so dumb to just let the accessory/electronics battery just go full flat?
@@curtchase3730 It doesn't just "go flat" - it charges the 12v all of the time. This is only a problem if the 12v battery is faulty.
Every car is dependent on a 12 volt battery…. ICE or EV…. No getting around that
the answer /cost and complexity
@@harriettanthony7352 Are you on the Tesla Engineering team or is that your guess?
Chris, how is it that those two frunk wires can be stored next to each other on the same little tab? Why don't they short?
No power to them I’m assuming
Using the same cigarette plug splitter than yours in another car :D The Tesla is freshly acquired though, so I don't wanna start installing sticky stuff everywhere (yet). Also, nice informative video. Sadly, I thought that the frunk was actually safer than the trunk, but now the bad guys (who previously broke the small windows to open the trunk), will start carrying this small battery with them as well, so they can also check the Frunk.
Does not work if the 12 volt battery is healthy..
Nice video, great info!
I'm homeless in my 24 year-old Toyota Sienna and now I know the secrets of the rich 😂
Basically we just got schooled on how a criminal and law abiding individual can open the frunk despite what he claims.
I had already done this with the same A23 battery. Well explained and informative video!
Mine died at the Baker superchargers on my way to Vegas. Tesla sent a tow truck and took us to the service center on Sahara.
I am shocked to learn that anyone can open my frunk
My doors are locked and battery is dead and the 12 volt battery trick did not work for me. I hear a click noise when I tried, but the fronk did not open. What am I doing wrong?
Hmm. You used that small battery ??
@@EverydayChrisI called Tesla and they are coming to replace the battery. I think it didn't open because the doors are locked.
@jeffstanner keep me updated! I’m curious to see why it wouldn’t open the frunk still since it should know the battery is dead
Tbh, this seems like to much for a guy looking into buying a EV. The ICE ones seems more user friendly
You can't jump start a battery. You must charge it if chargeable. My prius 12V battery powered the computer which allowed me to start the car. I'm not sure about my model 3.
with all that gear its just cheaper to take it to tesla to get replaced.
Oh he definitely got me on on that electrocution 😂
Me too. Good one !
@@chandansrajsame!😂😂😂
Tesla's 12 volt battery only lasts 3-4 years? That's pathetic. The battery in my 11 year old Toyota finally died after 11 years and I live in a cold climate. $54 billion bonus!. LOLOL . . .yeah, right .
Basically just showed how to break into a frunk lol
Only works if the 12 volt battery is dead… this won’t work if your battery is good…. So no you can break into a frunk
Can we work together? We Have New product launch requires test video.
A tie thing that you twist. Hmmmm twist tie? 😅
hahah
Even with that battery there they can't start the car can they? I didn't think so.
Note the newer Li-Ion batteries (vs Lead Acid) operate around 15-16v. The manual says you should still be able to jump start them with 12v packs, but I haven't had to try it yet.
yah that's why the higher amps with the jump starter matters based on people who's new 12v died
This video is great. The man literally covers every base possible with a dash of humor.
6:02 Btw, there’s a saying, only unlock your Tesla , then can open frunk by battery. So, still safe!
Ah...a 12V battery dying within 3-4 years doesn't sound right. On my old Diesel it lasted more than 10 years...
Highly depends on where you live. In Phoenix the hot weather eats up batteries on nearly a yearly basis
The frunk hack cables only work if the 12v is dead, or if a car door is open.
Now to remember to replace the little battery every 2-3 years so that it’s not dead when I need it. I can’t find a lithium-based 12v little battery like the a23, which would have a 10-year shelf life.
Someone said they just replace it every 3 years regardless. Mines coming up.
Isn't that kind of a waste and unnecessary pollution to replace components when there's no sign that they are bad? Especially a battery? Doesn't the car charge it like it is with ICEs? I was used to factory batteries lasting 6-8 years in normal cars. Looking into Teslas but confused tbh.
@@bencze465 My 12v on 2018 Model 3 lasted 4.5 years (65k miles) before getting a warning to replace it.
how on earth could a jump starter for an ICE car not have enough amps to "start" and EV???????
you should've told people that you can only open the Frunk using a battery this method ONLY:
1.) if the car is already unlocked
2.) If the 12v battery is already dead
So should definitely be safe against criminals : )
I think frunk won't open if your phone is not conneted.
But how do you unlock the car door, when the 12v battery is dead?
I hope you are right.
Secret is no longer a secret. :)
Is this screen mode available on model 3?
So don't store important stuff in your car. Generally a good idea anyway.
I was looking at the CB manual on line and there is a similar process for it. Located near front left side bumper. Maybe you could do a vid on it?
I meant CT Cybertruck
haha yeah I talk about it in everything you need to know about the CT video. But I do want to try it out soon prob with a short!
wait the frunk can be opened with 12V battery?!?!? without the 12V battery dead?!?!?!???
WTF??!? gonna empty my frunk!
Bump-frunk..bruh! Next to batter gonna store a mini twix or beef jerky, cuz ya never know.. hm. Maybe a mini fishin line an hook?!?!? Let's go
Thanks for the video, Chris. I had this happen on my 2019 SR+ Model 3 with no indication one lunch hour at work. Had to get it towed to a SC. I'm proactively replacing my 12v every three years going forward. I live in Canada so I'm sure all the cold starts wore it down quite quickly.
I've always called that "zip tie" thing a "twisty".
Does this work if I want to steal stuff from other Teslas frunk? 😂
Description says it will open only if the Tesla is unlocked. Will not work if it's locked.
Every 3 to 4 years!? 😂 just replaced a 13 years old lead acid battery from my Audi
I just had to replace my battery today and Tesla quoted me $110 for mobile service but it would take almost 20 days for my appointment. With the warnings in the car telling me that the car might not start again after being parked, I started shopping.
O'Reilly and Auto Zone don't carry anything for Tesla (outside of wipers) but Advance Auto Parts just started carrying these batteries in June 2024. I managed to get one shipped to store, but the price tag was steep at $300.
There are a lot of videos on UA-cam showing to to replace the battery yourself, and it was extremely easy. The only tool you'll need is a 10mm socket. Took me about 15 minutes and was very simple.
This is so necessary I’m gonna do it right away!!
I also am looking to order the EVJect product soon, very good for safety!
What about the newer Tesla's with the 16volts ?? The truck has 48v hehe
the 16v is 4 better. long live Spinal Tap.
We had a 23 mylr. Tried doing this and frunk doesn't open. Used 3 different brand of portable jump starter. Nothing happened, I used T8, dbpower, and noco. The only diference is with noco the vehicle was making a noise that it was responding to the jump starter. With T8 and dbpower nothing.
Great content!
Why would they not put in a device to convert the voltage down to 12v with the main battery then you would never need a 12v battery.
In two words--cost & complexity. You might add weight and where to put it.
My car just dead in my garage . I was so mad
Replace the battery before it dies - dude.
Great stuff, I have a battery jump bank, but couldn't figure out how/where to safely store a 9v battery... the little A123 batt in a baggie is a great idea! and remember: this is ALSO very useful not just if 12v dies after 3-4yrs+...
but also if your HIGH voltage battery goes completely dead when you ran out of range, since... the 12v batt runs out of juice very soon after, since no HV batt to recharge it, then... by time tow truck gets you to supercharger, it's dead, and ... you still can't supercharge, he has to jump your 12v... this can help if they don't know how.
As you pinned comment, this method won't let thieves into frunk in normal situations. Still the best place to securely store valuables. It only helps when batt is dead and car locked, eg emergency.
re the jump starter, I don't think the Tesla needs very high current/amps capacity, since there is no heavy starter motor current inrush...
just needs enough to get the low-voltage system bootstrapped enough, to let the HV contactors close, so the HV batt can run the DC:DC converters (like alternator) and provide 12v power to system, ... letting you supercharge, not just open doors / use touchscreen.
Hopefully more tow truck operators get savvy w/ EV low-voltage batt jumping...

Seeing your surroundings I immediately thought.... thats Irvine! lol
Yeah. I lived in Irvine back in the 90s, right off turtle rock
Tesla frunk should be able to open manually from inside the car like ICE car can do for centuries. Tesla needs to fix this. I preemptively replaced my 12v battery after 3 years due to this issue. With my ICE car, I'd go 4-5 years before replacing my 12v battery and I feel very safe with portable jump starter in my trunk.
My 12v on 2018 Model 3 lasted 4.5 years (65k miles) before getting a warning to replace it.
You can't get in the car, so that wouldn't help. This is a genius workaround for the massive convenience of no keys, for a situation that will never happen to the vast majority of people. All the people in here who don't own Tesla, stop complaining about what you don't understand.
I have a 2018 Model 3 now for 6 years without getting a warning to replace it. Which 12V battery did you buy as a replacement? I've read this blog several time and found no answer??? Amazon does not say Tesla in any descriptions. The battery(s) would probably work, but....
@@varcalli
OEM battery. Tesla mobile service came to my house and swapped with a new one for $125. It was quick and easy.
So basically anyone who has a A23 battery can walk around (at the mall) and open any Tesla's front truck relatively easily and take whatever is in the front trunk. Knowing this I won't be storing anything valuable in my front storage area now 🤔
Weird question, but does your model 3 inspection checklist cover 2021 Teslas or just the newer ones? Getting it because PICTURES!!!
there is also a USB-C to 12 V adapter👍
And I thought that Elon musk supports self maintenance and repair model.
How is this design convenient or takes a very common issue of dead 12 v battery into account, if you cannot even open the hood or access the battery for jump start.
funny edit haha
5:06 Twist Ties/Bags Cable Ties/ Bag Twist Ties/Cord Twist Bread Ties/ Reusable Black Plastic Coated Ties . You are welcome
Info item, I put in a soft close and the A23 doesn’t seem to pop it. I like the soft close though! (Also the car should tell you the 12v is dying. Mine did and they fixed it in the driveway no charge.
Can you do an updated video on newer Tesla’s that now come with 14 volt and 48 volt batteries instead of the old 12 volt batteries ???
Why a23? Any alternatives?
Question for anyone who can answermy wife does not like when she's driving. How the tesla shows all the cars in different lanes. ( I know one of the Biggest features of the car)
Is there a way To shut it off
How are you keeping all those batteries and jump starters in your car? With the difference in temperatures they are not going to last more than a few months before they expand or worse...
My 12v died with no warning this morning as I was leaving for work. Can’t even unlock the car.
There is no such thing as a cheap (under $300) jump starter that produces 2,000 Amps. They are lying.
23 and beyond has a 16V 10 Year Lithium Ion pack. Problem solved.
That jump stater works great!
The 12 volt battery has been replaced by lithium 12v battery last year and should last the lifetime of the car or so we hope.
Those jumper cables don’t work for my Tesla model S but however a big jump box will work for my Tesla
hi Chris great for share.
my question in case car is not thing wrong so the robbery use AA battery use your formula to open Trunk ?
thanks
No one can open your frunk because that doesn't work if your 12V is working correctly.
Wait but, by doing that that means people can just steal whatever I have in the front? 😅 By doing that no?
How about jump to another gas vehicle?
I heard that the front access port won’t work unless you have low12v battery. Thus theft can’t steal. Can you confirm?
I guarantee you once the battery is dead there will be no camera recording and someone will jumpstart the front and get into your damn car
My model S is four years old so recently I preempted any 12v failure - I hope by having a replacement fitted. Here in Australia we can be hundreds of miles from any of the few service centres and there are almost no mobile vans. Better safe than…….
This only works with A23 battery? How about double A?
The A23 battery is a dry battery consisting of eight LR932 cells, with a nominal voltage of 12 V.
sheesh. Correct AA wont work
Thanks for your videos. I have a question about cruise control. With all the current software updates, cruise control is no longer available like it was before. How do access this option?
Wonder why Tesla doesn’t display battery voltage.
Aren't you also teaching people how to open the car without key?😅😅😅
Most helpful. Thank you.
