Good to finally see a demonstration of this. Thanks!
Good info, thanks. I knew about this on a theoretical level, but I had never seen it done.
You can tape a 12v camera battery to the cables and be sure you have a battery accessible to use all the time Battery A123
Not an A123, but an A23 battery cell. I and a few others keep an A23 in a ziplock bag behind the tow hook cover. The A23 is a tiny 12v battery and about half the size of a AA battery. And it will open the frunk (I tested it a few times to make sure).
Only downside to a portable jumpstart kit is that it's probably in your trunk, which is locked until you get the frunk open and power to the 12v battery :P
That was exactly my question
I keep my portable jump starter in the frunk for that reason. I keep an A23 battery in a ziplock bag behind the tow hook cover. The A23 is a tiny 12v battery and about half the size of a AA battery. And it will open the frunk using the two wires behind the tow hook cover (I tested it a few times to make sure).
Thank you very much for sharing this video. As an enthusiast I had no idea about this.
Good and practical content. Thanks!
Great video! I needed to know this before I have to replace my battery.
Thank you for another informative and clear video on an important topic. You have convinced me to keep that 9v battery in my console or glovebox. again thanks
You should store the 9V behind the tow hook cover because if your 12V battery dies and your doors are locked, you won’t be able to get into your car. So leaving the battery inside your console makes it useless.
Another terrific video Mike. Thanks again.
Thanks for this video! Really convenient that it can be powered with a regular 9-volt battery!
One tip if using a NOCO booster as shown in the video -- it has polarity reversal protection so that it won't apply 12V unless it detects it's hooked up with the right polarity. So if your 12V battery is dead enough, the NOCO won't recognize that it's hooked up correctly and won't apply 12V, unless you press and hold the "!" button for about 5 seconds. Be sure its clamps are not touching each other if you do this.
You are the first one that mentions this of numerous videos that I have seen with the Noco pack. Saved me about a week of frustration. Thanks dude!!!
Does the NOCO actually charge the battery if the clamps are connected? I know that it will give it a jump so I can start the electronics or a normal car but what about if the clamps remain on does it charge for a certain pair of time or does it not charge continuously? Good tip otherwise on the dead battery and having to do it manually.
Again an other interesting video especially with the use of small smart charger. I have the Noco Genius G750 that I was using for my previous ICE car to keep the battery charge when I was on vacation in Europe. Thanks again for those nice videos
Life saver! Video was so helpful. Thank you!
Great video - very informative.
Well presented. Thank you.
Great video! I just purchased the HULKMAN Alpha85 Jump Starter 2000 Amp 20000mAh Car Starter for up to 8.5L Gas and 6L Diesel Engines with LED Display 12V Lithium Portable Car Battery Booster Pack on Amazon which had excellent ratings. I will also tape/store a CR style round battery in the lead terminal areas to get the frunk opened, and this pack inside the same arera.
Great video - learned something I didn’t know. Thanks!
I just tried it out with 12v battery (tested), careful contacts, proper polarities, doors unlocked. Trunk didn’t open at first, but I’ve realized you need to keep the contact on for two seconds, then it opens. Model 3, Dec 2018.
Project Farm did a really good in depth comparison on those charger packs. I suggest you watch that before deciding which to purchase.
I have the NOCO GB70 and it is great
Thanks Frugal..!
Got me out of a jamb!!!
Thanks. This really helped me out
Glad to see it works with power Frunk installed
No power frunk with a dead 12V battery but it should pop unlocked anyway.
Thanks. Everyone should try this in their garage because it can be hard to fish out the positive wire. On my 2020, the negative is attached to the access door with a zip tie. I put a 12V A23 in there.
Thanks Mike.
Awesome tip, 👌 thank you
Good video Mike! I like the way you explain things. Shortly after getting the car, I tried to be a little proactive and decided to pop off the round cover and open the frunk with a 9V battery. Guess what? There were no wires! I thought the factory forgot to install the wires. Tesla sent a mobile repair technician out. He said he had run into this a few times before. He somehow fished around and located the wires under the left fender, and moved them to the round access hole. He mentioned that if he was unable to snag the wires, the fender would have to be removed😖😖 Luckily it never came to that.
That’s crazy! I’m glad they were able to get access to the wires.
Damn Tesla quality control
@@FrugalTeslaGuy Does the Model Y come with the red lead already covered, or do we have to cover it with electrical tape?
😊😊
Thanks for the video. How do you get those Tesla commands/shortcuts on your watch?
While my 2019 M3 was parked for 37 days and plugged in to home charger, the 12v battery died. I thought it was my Tesla phone app so I updated my phone app and re-booted the phone still car would not 'start'. Called roadside assistance and then discovered how to open the port in the front bumper as I watched the Tesla RA tech. Connecting a battery to the two leads that pop out you are able to raise the 'frunk' lid and get to the 'little' battery. While his charger was connected drove the car out of condo garage where my Tesla was loaded onto a flat bed tow trunk and this was about 5pm Sunday evening. Next day Tesla repair replaced the defective battery free of charge and now my car is new again. Tesla even sent me a coupon for free UBER ride to pick up my car. This is the one and ONLY problem I have ever had with my Tesla. Tesla is a great car and a great car company.
Thank you. My car was flooded and now dead. This was helpful. Any way to open the trunk from the outside? And a door to get in to access interior? I found the video on how to unlock glovebox.
Great simple video.
Does the Model Y come with the red lead already covered, or do we have to cover it with electrical tape?
Very cool video, thank you!
Very educational.
You can also use a cheap hank crank generator to create the voltage to open the frunk.
Nice to see that a 9V battery will work to open the frunk! Those can be purchased almost anywhere and are easy to carry with you.
The a23 appears to be an even better choice. Way smaller and it’s 12 V
@@chezchezchezchez It is now reported that 9 volts won’t work anymore, it must be 12 volts. Maybe this is only true for newer cars, I don’t know. 12 volts is a good idea, in any case.
@@AlanDayley didn’t know that. Thx
@@AlanDayley can confirm this. Tried to open frunk with a 9V on a 2019 model 3 but didn't work.
Really helpful to hook up a 9-volt battery plug on to those wires
What does the yellow handle for the automatic opening and closing frunk do? You can't leave us hanging. It doesn't open the frunk manually?
Excellent.
Ryobi 18 V, or any other drill battery works if applied for a second to pop it open.
I know We’re talking about the battery but that’s also where the tow hook screws into as well. Figured it mention it for anyone wondering what else that hole is for
Where would I keep the power bank? I hope I won’t have to carry it around. Also, would I have to just carry around a 9v and a screwdriver?
thanks for this video! Personally I don't like to put the electric tape stick against the metal, so I wrap backward with the sticky side out for one revolution, then wrap the sticky side out with sticky side in. This keeps the metal free of nasty stickiness.
That has enough juice to charge to turn on the car and give it enough juice to drive to a charger? Saw another video where someone did that but I couldn't how it charges the main battery to drive it.
my battery jump started would be locked in my car...so how would I get inside to use if the car door is locked?
I love that this small 9V battery did the trick.
Note that if you have a portable booster and you are in this situation with a dead 12v, you won't be able to access the booster if it's kept ANYWHERE in your Tesla - cabin, glovebox, console, frunk and trunk will all be inaccessible. Keep something in your garage and have AAA service.
Maybe taping/hiding a round camera battery in that power lead area, and a portable battery charger in the frunk is a work-around?
I and a few others keep an A23 battery in a ziplock bag behind the tow hook cover. The A23 is a tiny 12v battery and about half the size of a AA battery. And it will open the frunk using the two wires behind the tow hook cover (I tested it a few times to make sure). I keep my portable jump starter in the frunk.
@@android04 is it safe to keep the portable battery chargers in the frunk? Do they risk getting too hot and causing potential fire issue? Curious because what you state is exactly what I’ve been considering doing.
what about the yellow hook cable what is that for??
It sure would be nice to have an actual key to unlock the doors, and then manually pop the frunk with a lever. I'm not that unusual in that I go to remote areas for backpacking, etc and kinda need to depend on getting access to the 12v and my jumper cables/jump starter without hoping my little battery I carry around with me/tape to car isn't dead, and that the 12v car battery is dead enough to allow the frunk to open. Too many ifs for that kind of situation.
@ 6:50 Attach the positive cable to the plastic cap and it will be insulated, but honestly, if it comes from the factory uninsulated then it's unlikely it need to be.
Yeah I have it, the Noco, and it’s amazing. Recommend it.
What about if the doors are locked? I can't use the app or access remotely?
I'd want to protect the positive lead with more than a little electrical tape that will get could fall off with heat and cold cycles. There should be a solid plastic case-like cover or zip tied sleeve.
Hey FYI. If your 12V battery is truely dead then this doesn’t work. At least not on a 2018 model 3. I had a situation this weekend where my 12 V battery died and I grabbed a brand new pack of 9 V batteries and it would not open. I ending up waiting for the tow guy to bring a 12v battery charger to open it up. If your battery is ok and unlocked then this may work.
12v Battery dead and frunk opening procedure also doesn't work. Happend to us today. No idea why we couldn't power the front latch motor. Removing the M3 from the garage now will be a huge problem...
I have the gb70 it’s a life saver
How do I access the 12v battery from the inside???
Yes…… just another pain in the ass, proudly presented to you, by the designers at Tesla. Have fun figuring out how to make your car work when it won’t work ! 😊
So forgive me if this is a dumb question but I do have one of those portable chargers but if I leave it in my car and the battery dies, how do I get into my car to get it out to open the frunk?
I and a few others keep an A23 battery in a ziplock bag behind the tow hook cover. The A23 is a tiny 12v battery and about half the size of a AA battery. And it will open the frunk using the two wires behind the tow hook cover (I tested it a few times to make sure).
What do I do when the battery trick does not open the frunk?
Does anyone else find it ironic that the first option is to find someone with an ICE car to rescue the electric car?
ALL cars would need a jump if their battery was dead 🙄
Where would I keep the jumper cable device? If the car is locked, I won’t be able to get in. Also, I don’t carry around a 9v and a flat screwdriver.

Use small a23 battery taped to inside if the little access door. This happened to me, all power lost, doors locked car in shut down , no access to anything. On the flatbed being towed, couldn’t get it off the truck. If I’d know this it would have helped.
What if my Tesla doesn’t have that compartment thing
upvoted
Is the 12v battery under the same warranty period as the big battery of Model 3?
No. It's under a 50,000 mile warranty.
@@FrugalTeslaGuy , too bad. Many model 3 seem to have 12v battery problem after 50k miles.
Is there any voltage shown from those wires if the 12v battery IS charged?
If there is, that means we can hook up a high amp draw to those wires til the battery dies, which disables the door lock function,which lets us into the frunk anyways
God bless this man somebody please feed him.
Nice! Do you have any idea of my health status? If not, then I suggest you keep comments like this to yourself.
But how do you unlock the doors if the 12V battery is dead so you will be able to pop open the Frunk with the 9V battery? Isn't the 12V battery responsible for providing power to unlock the doors?
I had the same question
@@paulleary2312 I'm guessing once you pop the frunk and replace the 12 volt battery then you'll be able to open the doors...
The frunk doesn’t open with the two wires on the front of car with the doors locked.
So back to the question How!!!
ok.. So about that watch? Where can I get one?
Yeah, I was wondering about that too. Which app are you using on your watch? I didn’t think the Tesla app has an Apple Watch companion.
im interested in the auto frunk... lets do talk about that if we can, in what ways does it change getting into the frunk with a good on bad 12v ? i hope your able to reply or message me
Upon installing the auto frunk a pull lever will be run through to the tow hook opening. By pulling it along with using a a power source (9V battery/jumper) will open the frunk latch.
ICE cars never thought of that. Cool for something really hot lol Live early would love to have electric vehicle for the 20 mile round-trip’s
Question. Can you unlock the doors with the 12 volt battery being dead? If your doors are locked, and the 12 volt battery is dead, can you open the frunk with this process?
According to Tesla, yes.
Yes, the 9v battery or other battery (I recommend an A23 battery instead) powers up the circuits and mechanism to release the frunk even if the car's 12v is dead. I keep my portable jump starter in the frunk for that reason. I keep an A23 battery in a ziplock bag behind the tow hook cover. The A23 is a tiny 12v battery and about half the size of a AA battery. And it will open the frunk using the two wires behind the tow hook cover (I tested it a few times to make sure).
@@android04 it didn’t for me
My 2019 doesn't have an electronic frunk.
I forget. Why can't you just pull the cable?
What’s the purpose of the yellow handle/cable?
That yellow manual release comes with the Hansshow power frunk add on.
czcams.com/video/h2aiTwg3Apk/video.html
The security on that is amazing...they really thought of everything didn't they?
Great video!
Sorry I'm clueless about electrical stuff but you made it simple.
Does it mean that you can open the car but just not the Frunk if your 12v battery is dead?
@paulbeaudette8788's comment threw me off. What good is a 9v battery in the glove compartment if you can't access it? Is the 12v used to just start the car?
WHAT HAPPENS IF THAT DOESN'T WORK ? HELP !!
Hate to burst everyone's bubble, but a 9V does not work when the 12V is dead. This has been changed to require 12V. It says it right in the owner's manual. "Locate an external 12V power supply (such as a portable jump starter)". I also know from personal experience. In 2018, a 9V would open the frunk, even when the 12V was fine and car locked. This triggered the alarm. After an OTA update between then and now, a 9V did not open the frunk with a dead 12V battery. I then used a portable jump starter and it opened right up. Also, you should get a warning that the 12V needs replacement about 1 month prior to it being completely dead. So you should almost never be in this situation. You can't just go to AutoZone and get a new 12V battery. Tesla had to send a ranger to replace it.
I'm not sure if it's true that a 9v battery will no longer work if your car's 12v is dead, but it's better to use an A23 battery instead of the 9v anyway. The A23 is a tiny 12v battery and about half the size of a AA battery. I keep the A23 battery in a ziplock bag behind the tow hook cover. And it will open the frunk using the two wires behind the tow hook cover (I tested it a few times to make sure). As for being able to find a replacement battery at AutoZone or any other parts store, you actually will be able to find one. The Tesla uses a Group Size 51R battery which is commonly used on Hondas. You will be able to find that anywhere that sells car batteries (barring any stock or supply issues, of course). You need to find or ask for "group size 51R" specifically, because their computer system will not find a compatible battery for a Tesla.
I got the 12V battery message and it was dead right away. Not much of a warning 😂
I locked my phone in the frunk and couldn't open the car and had to get a lockout request...
Tried to open the frunk this way but it wouldn't allow me. Now I know why lol.
By the way, we were in the mountains so the car had no internet connection.
Thanks for the DIY tutorial. Much needed as I was surprised how "unprepared" I was for my 2018 Model 3 dying 12v battery. Lol.
Also, side bar note: Moving forward, do NOT put any valuables in your frunk, now that it looks like everyone / anyone could now easily "break into" your frunk, simply with a 9V battery....
@Norm Toy :: Check the end of the video. It can not be broken into this way.
Mark, great video. I was hoping you would also comment on what happens to those of us (like you!) who have the automatic Frunk (eg Tesla Offer)?
I’m a little confused as to when you would use the battery method vs pulling on the provided loop cord to open?
My biggest fear with the automatic frunk is the horror stories I’ve read of some people being unable to get into their frunk and having Tesla pry it open for a lot of money.
If I had the battery backup in my car, but everything is locked and the battery is dead, I'm essentially SOL?
Unless you can find a 9 volt battery somewhere. I guess so. 🤷♂️
I keep my portable jump starter in the frunk. I keep an A23 battery in a ziplock bag behind the tow hook cover. The A23 is a tiny 12v battery and about half the size of a AA battery. And it will open the frunk using the two wires behind the tow hook cover (I tested it a few times to make sure).
can a thief drain the 12v til its dead off those wires, and then open it?
9V battery works fine
What amazes me when it comes to Tesla is their... divergence in design. Some parts are really cleverly designed and some parts, like this, is like something my seven year old would have designed better. It is like they, oh shit, we must solve this... ehm... well, just add a few cables we have lying around and drop them down where we have some kind of hole to reach them in.
I have a noco thing it is amazing. I used to have a large "jump box". The Noco is much smaller and lighter and holds charge better. I think it's even more powerful. Do not buy a big jump box anymore. That's ancient technology.
You do NOT have to electrical tape to insulate the positive terminal when finished. That's misinformation. My car didn't have that from the factory. They just use a simple 1 cent diode to protect this.
Didn’t work for 2022 M3
tesla has thought of everything
Except using a simple key
The question is, what happens if your cars battery is dead and its in locked state, you're unable to unlock the car.
It’s not working 😢
So dont keep valuables in the frunk. Got it!
It's like you didn't watch the video
How about just buy a gas car and throw that crap away😒
First Cement
100 percent USELESS
What the hell was this video for?
