- It would have cost me 200 dollar for a new key, now I changed it myself for only 5 dollar...
Please subscribe for more videos and comment if you have any ideas!
Battery: bought on ebay for 5 dollar. Search for: Panasonic 2020 with legs or BMW key battery
Sound: I do not own any of these rights. Please let me know something if it's against any rules. - Авто та транспорт
BMW should be ashamed of themselves for giving people a key fob that’s impossible to change the battery on , smh
@J B battery doesn't last forever mate
@J B ,
Thanks for your comment.
Hopefully, you will see my reply and respond to it.
My wife got the key fob wet, and its battery discharged (despite putting it in dry rice, overnight).
My question is: Are you certain that the battery is rechargeable and is recharged by the car's ignition switch?
I don't want to "cut" my key fob apart, and replace a battery, if it can be recharged by the ignition.
If you could verify the "recharging feature" that would be helpful. Otherwise, I will probably find out, after using the key fob for a few days.
Thanks.
@J B gcvv
i agree with you. what did they expect for the battery not to go bad, ever...lol
@J B that is only Mostly for 7 series, not 3
I used a Dremel tool with circular cutting blade and it took me one minute to disassemble the two pieces. Then sealed it back up with black silicone. Thanks for the video and battery identification.
You should have tested your remote after you replaced the battery to show people the remote actually works with the new battery.
Thank you for the video, I didn’t know how to replace the battery for this type of key. Will save me money, thank you, I’ve liked and subscribed 😎
I'm so close to being done with bmw, period. Plastic parts, recalls , ridiculous key fobs .... I really don't have time to raise a car like a baby.
Add to that egr intake swirl flaps vacum lines dpf problems.
Does the key have to be reprogrammed after battery change? I only have one key on me so I'm hesitant to do this.
BRO i did the thing as you showed but key functions good but it can't go into the whole so i can't start my key the key anymore because it doesnt fit anymore...please you have advice to help..?

Great fix! worked for me, thanks!
Hi, there is any time until you must replace battery? I heard something to change until 3 minutes, right?
Sorry for my wrong reply to WheepyMAW ! The battery is really RECHARGEABLE. It recharges through the LC 125 kHz resonant tank on the same PCB side where the battery is mounted. But, as any rechargeable battery, it wears out as time passes and recharge number increases.
So a battery substitution becomes unavoidable after many years. You can try to fit a non-rechargeable battery, but it will suffer overheating and power drop if car is used (the key is in car immobilizer transponder range) for long times.
For door open / close there is a separate 315 / 433 MHz pure transmitter IC supplied by the battery with a separate, different antenna.
Nevertheless I cannot guarantee that you do not need a rolling code reset of the part by some specific SW, that is to say it could be you experience a fail in the substitution.
What yr & models does this video cover - thank you 🙏
I did the same thing, the car starts but the buttons dont work, what should I do to programm the buttons?
Could you have softened the already made solder and changed the battery?
Your a top man, thank you.
Thank you very much for the video!
Which battery should you order?
Worked ! Thanks
have you programmed your key?
thank you!
God bless you
Pde yg tengk video ni kalau xpandai buat jgn buat takut remote tu rosak😇 sekian terime kasih
Usefull!!
Thanx. Easy fix and everything works again.. also the open and lock buttons.. thanx for the video.
Does CR2025 fit in?
Wat voor batterij?
How do you remove the battery? It is soldered in so it can’t be removed.
No links to the battery like you said you would.
What is the battery size?
Bkn ke dia cas mase kte dh masuk kan kunci tu time nk bwk keto
Does anybody know my solution? I bought a new key transmitter at the dealership and it doesn’t work. The old and new don’t work. The car starts and runs with the key. The central locking system works fine. All Door lock actuators work. But the remote won’t open the doors. The dealer thinks it could be an $800 antenna job.
Jonathan Reed try to code it first? It would be weird if closing etc works but opening not. 800 looks btw way to much! Stealership😏
try checking fuses behind glove box
It may have lost the immobilizer code, and need reprogramming, which means taking your car & the remote to the dealership. Where I work at Hyundai, we charge £60 for reprogramming a key.
You mean *Stealership wants $800 for BS
Better check out another video, because it’s a lot easier than thus guy is saying!!
My kee vap did not work before replacing the battery and it did not work after . Any Help
They need to be programed if allowed to go completely dead.
HO ACQUISTATO IL GUSCIO PERO NON MI E' ARRIVATO IL FLEGINO BMW COME MAI SI POTEVA INCLUDERE PAGANDO QUALCOSA IN PIU.
IN Malta i just bought a new fob for €313.64 !!
and did it work? grtz
Okay, so I've followed this method. Opened the casing, desoldered, took off the old battery, soldered on a new 2025 rechargable battery.
The key still does not remotely lock or unlock the car.
Went to several key specialists who said to buy a new key which will cost around £120 and check if it works. If not, then it may be something else in relation to the car.
They have checked my key using a machine that checks the signal and it is giving out a strong signal every time it is pressed, even they are baffled to why it does not lock and unlock the car.
Is there another solution? Does the key need re-programming when a battery is replaced?
They told me if the key works inside the car to start then there is no point paying to have it re-programmed as it is fine. I'm not sure what to do now. Anyone?
I just saw a video on Nathan's DIY about replacing the multi antenna. It was causing odd problems like yours
I have the same problem on my spare key. Did you find a way around it?
@@ryanpotter8550 May sound silly but tie about 4 or 5 elastic bands around it tight. Mine worked this way and is still working.
I think tightening the plastic around the key may allow it to connect better inside.
I asked a shop that specializes in foreign cars and Grady said that reprogramming the key isn't needed after a swap. In case you are wondering the shop is Red Ink Racing Ltd. in Lawrence, KS.
Apparently, you can recharge the battery simply by placing it on a rechargeable toothbrush charger or any wireless charger. The bottom part must be over the charger.
I put mine in the microwave on high for 3 minutes and its good as new.
@@moy_moy85 Didn't work (on the toothbrush charger) Putting it in the Microwave is a stupid idea and some people may do that. DONT USE A MICROWAVE putting any metal in a microwave causes arcing and a battery will explode. BAD ADVICE
10 year old batteries are still 10 year old batteries
Iv tried wireless charger but couldnt get it to work. Will just do this an swap the battry out now though
Need to make Car Key and put 4 Scroo to open I'm not like this type of key
Couldn't you buy a fob with a blank key and just switch keys?
What the heck is this noise? Is this music or whatever it is, so disturbing.
I honestly think the motive of this entire car was to rob the owners of every single cent they had. I used to love my car and now it barely works bcuz I can't afford the software like it's really mind-blowing as to why BMW did this
True. It kicks 200€ per week from my pocket when its in good mood.
Wtf Is a B and V
deutsche qualitat
This is one of those BMW decisions that is quite frankly, utterly ridiculous.
What??? $200????? you have been rob dude. I paid £15 in UK
Where? My key fob just died and I can't seem to find anyone that has affordable prices.
Battery number plz
ul2020
2020 3 volts
CR2032 3v
Why are there three answers here ?
Panasonic VL2020 _ 3v rechargeable (made in Japan)
Proof that BMW intentionally employs anti-DIY designs in order to gouge their customers. (eg. car battery, key fob battery, front head lights, etc.)
Bro you already did the work before starting smh
you are confusing us
All that just to change a battery smh
Haha half the job was done before you started recording!
Absolutely so bad that's not how you hold it and do it
Wtf is this?it was like this,it was like this.Show how to replace step by step
This is bs.. hate we have to go through all that just to change fuckin battery..
Poor guide, a step by step video shouldn't have parts you have done already off camera.
Wat th fuk r yu saying
Be carful. Removing the battery seems to erase the frequency for lock and unlock. the car should still start. There is no way to reprogram these keys that I have found.
Yeah you can reprogram the keys but it’s a pain in the butt, gotta use INPA, or tool 32 and recode the cas
yep this is my issue right now... still no lock or unlock
I put the new VL2020 battery in and it required no reprogramming on my US 2012 BMW Z4.
All type of cars key like the which one open with blade Fuckan ass enginior how's make keys .
uhh... ?
Ridiculous video. You show us how to replace the battery that you already changed. Most of us have never changed ours. Not helpful.
He literally showed u exactly how to do it
These batteries are rechargeable so why confuse or make people panic about it?
Just insert the key & start driving it will be charged itself 🙄
it still dies eventually dummy it’s a battery
What a kak video. My herder.
I hate German technology for on single thing: they over-engineer everything. It seems their specialty is to transform the simple into complicated. Other than that, they are the best but I will NEVER buy another German car.
Scienzia', ...tanno spiegato che la PILA deve esse RICARICABILE e pure de VOLTS adeguato ???!!!!
pretty sure it's a bad thing to get skin oils on circuitry. some latex gloves wouldn't be a bad idea.
