BMW Key Fob Battery Replacement (Comfort Access) 

Why would 173 people dislike this video? Nice work man clear and to the point. I was about to buy a whole key. I'm going to try this out today

Thanks for this Justin, really helpful. In case anyone else is interested, my old Duracell 2032 batteries (in both my key fobs) lasted less than 18 months each. I'm in the UK. My remote locking and comfort access stopped working and I thought the worse: I hadn't used my E93 that much and wasn't that familiar with its operation. I put new Duracell batteries in both keys when I bought the car about 2 years ago so I thought that was that. However in desperation I thought I'd check the batteries just in case. Yep, both were dead! Put in new Panasonics and all is working again. I must say I was getting cheesed off using the emergency key to unlock, then leaping in to cancel the alarm each time! Thanks again.

Hey great video,just got my 335xi as a first car and all your diy videos are definitely going to help!

You made my life so much easier! Thank you!

Keep it up dude your content really helps the younger crowd preform DYI's. I just bought a 2011 328i :D !!

Nice and simple video with a little extra knowledge on comfort access Thank you so much !!!!!

Legit perfect timing! I just got the message today for my key fob!

Thank you so much for this video!! I had just recently sent of my comfort access key along with my cas unit to be programmed to a new msd81 dme. Got it back and was super bummed out that the key wasn't working....... bmw was quoting $500 for another key........... you just saved me $495 😲💯

Thanks alot Bud. Short and effective video

Thank You! Been trying to figure it out for a couple weeks now. People tell you to break the fob open just to have to solder the battery back to the motherboard and super glue it back 2gether. I'm so broke I wouldn't be able to buy the glue let alone the soldering materials. But, I do have grey duct tape! Even the hamster in the wheel under the hood has grey tape on him. Your the best in the world.

Literally just like you said saved me a trip to the dealer 🤘🏻👍🏼 thanks for your vid lol

Thank you for taking the time for the video!

Worked perfectly. Thank you!

This is the first video about battery replacement. Nice one 😀

Yes this video saved me a trip...made my day.....nice one

Thanks sir. Did not know my bmw key was comfort one. Discovered that just now after watching your video. Pulled the old battery and tomorrow will replace it with new one. Thanks !

Very simple, thanks man !

You're always helpful..thanks.

Thank you! Thorough and brief.

Best video for this key fob. Thanks

I love this channel, so helpful! Thank you so much!!

Thank you!! I thought I was going to have to go all the way to the dealership.

Thx so much, was literally trying to pry open the plastic from the sides before i came across this!

thank you so much... really happy that i found ur video...

Thanks man!

works perfect. thank you!

Thank you!

Great informative video, thanks alot!

Great, You saved me a lot money, I was gonna get a new key!! your awesome, thanks

Thanks for the video--wasn't sure how to open it on my own. Extra tip for ultra-lazy people like me who can't be bothered to walk to the toolkit for a screwdriver--the narrow tip of the emergency key can also do the screwdriver part of prying up the cover.

Excellent video. Thank you

thank you!

Superb easy. Thanks alot for the video. Helped me alot..

Thanks bro...

Hey man love your videos. You should do one on how to program your key fob or car? To open your windows with the fob. Mine is not working for some reason. Keep up the good work. You got my sub!

Killer tip bruh

Do you have a video of you talking about the comfort access features on your BMW?

Thank you so much

thank u!!!! once my e90 comes body shop gonna change it.. was wondering why it won't unlock unless I'm really close to it

Nice works well on bmw e90 335i :)

Thx it helped

brill

Thanks ✊🏿✊🏿✊🏿

Cheers, easy-peasey!

Thank you big help! Question: one if the key pods were left in pants pocket and washed and dried. Now does not work. Answers?

Nice

Thankssssssssss❤

Thank you so much. My car starts showing this symbol this morning. I didn't know it's meaning

👍

how do i know if i have the comfort access or not?

maybe a silly question?? since the battery is being removed does the remote need to be reprogrammed? or is it just simple swap and go great video! You have so many that are quick helpful!!!!!!!!!!!!!!!!

def saved me a trip to the dealer

Great video, idk why im here, I can't afford a car, but I'd love to have a 335xi.

I have the E91 2006 with comfort acces. And we just replaced the battery but still no signal. Does it need to charge og be recodded ?

Link where did u get the battery from thanks

Killer

one of my car keys only locks the drivers door, what could be the problem?

A question is not deprogrammed the key? since I changed the control of a Jetta and the key was deprogrammed and didn't want to turn on

It is possible to transform a non-comfort into a comfort access?

I charge my comfort access key fob on my sonic care charger plate for the glass cup, works great!

So i got a 2006 bmw 325i and today i inserted the key and nothing happened ! it wouldnt turn on! :( any idea ?

Hey man, we got a "new" key from dealer when we bought our 2011 328xi. Intermittently the unlock button won't work, I try the lock and trunk button and both work. My other key then will also unlock the car when this is happening. Is this a low battery or does that button need replacing?

what you mean by this video won't do you any good what could happen? Asking because I do have comfort access(not working) however when I put the key in its place where it sits, it charges so uh unsure help pls

I have the same shape key on 2005 1 Series and I had to cut the plastic all around, replace the battery and glue it back on using some superglue.:))

Great vid.. hey my comfort access doesn't lock the car at times when walking away from the car. Is that due to battery being low?

Why can't I find the elusive little slot for prying it open?

This morning I couldn’t open my car to go to work I had to use the physical key lmao

replaced my battery and it didn't work, it sometimes works usually when car battery reprograms but recently no work at all. has anyone experienced this? i have a 08 3 series comfort access.

Justin, where can I find the coilovers or suspension like the one you have in your car.

How do you warm the engine of a BMW 320i E90??? Please help or do a video

why this one is different

Sir my key fob for e90 not same with your key. It is whole and cannot open the half.

Anyone recommend some good ob2 scanners to clear the codes when I replace something I don't like to drive all the way to the dealership just to reset a light

Should i code the key when i switch the battery or everything will be working „plug n play” ?

Hey brother. Are you still providing videos on BMWs? I'll subscribe if so as I own a BMW x series SUV and could do with a support line lol 🙃✌️

My windows and indicators don't work e92 bmw

I thought you were going to discuss regaining comfort settings AFTER replacing the battery.

Can one program a new key fob the self? And if so is there a video on this? Thanks .joe l

I put in three different batteries in my fob and sometimes the fob works and others it doesnt is there a sync i have to do ?

Just opened mine with my fingernail, things are never this easy.

CR 2032

Does that work with all E90 320i, 2011 models as well as my dashboard comes up with the fob logo showing battery Pic. How would I know if it's comfort access or not?
