3 years later this video is still a life saver

[@KeyFobRob]

Glad I the video could help you out! Take care!

[@JJ-zy3zv]

Thanks man. This is literally a perfect "how to" video. Simple, clear, to the point, but takes the time to actually show the steps. thanks

[@KeyFobRob]

I appreciate that!

[@hassanrahman6502]

Agree. No trying to over complicate things like some KZbinrs. Thanks again

[@amandadaering]

Agreed!

[@McNealyReilly]

Love this, thanks Key Fob Rob. Only thing I'd add is one mistake I was making -- I was squeezing the sides hard in when using just the key to drive the battery slot out. Wound up scratching up the key fob (still works). However, when you squeeze the sides AND push the slot out with the same hand in one motion, then only a minimal amount of key pressure needed. No needle nose pliers needed! Thanks again.

[@Sazyua]

You’re a life saver, thanks for the tip. It worked instantly in one go. The key method was a bit too hard and I also ended up scratching a little also.

[@abhiabhi5116]

This is the perfect addition the the video. Indeed doing it with just hand was much easier than trying with the key!

[@souljazzguitar]

Same. Couldn’t do it with the key. But worked instantly with @Sazyua one-hand suggestion. This video helped a lot though. Pointed me in the right direction. Thanks!

[@chemopia]

Good tip. The key is thicker than the space he’s poking the key into, and I broke it.

[@ripseeze_the_second5590]

Thank you! It wasn't working until I read this

[@mssmssmssmss]

Thanks! I bought a certified pre-owned Audi, and one fob failed almost immediately and the other about 8 months later. The technique you show is exactly how it works, but mine were not quite so easy to remove. Maybe my thumbs are too weak. But now I know how to do it rather than driving 20 miles to the dealership and embarrassing myself.

[@KeyFobRob]

Strong thumbs are a must! These things get really stuck. That's why I used the mechanical key to assist with sliding the tray out.

[@ChestnutProducts]

Clear, simple and to the point. Perfect 'how-to' video, thank you!

[@KeyFobRob]

Glad I could help ;)

[@desmondlew7244]

Thanks! Your trick to use the physical key to pry it out made it so much easier!

[@KeyFobRob]

Glad it helped!

[@stakaB]

Thiss was so useful! I’ve avoided the “your key battery is low” message to the point it barely works anymore haha, thank you lots

[@KeyFobRob]

Glad it helped! No more annoying message for a couple years

[@mssmssmssmss]

I didn't get a warning, and it failed in the parking lot when I was running errands. I read the owner's manual, struggled for a while, and drove back home.

[@AncientAussie]

Best video I have seen showing how to change the battery in the Audi key fob

[@KeyFobRob]

Great! Glad it was helpful

[@esapirttinen7116]

Thanks man! Just saved a lot of money as both keys were on low battery. Also liked that You went straight in to the business without any long intros and so on.

[@KeyFobRob]

Awesome! Glad I could help you out

[@MichaelStanwyck]

Thanks! I'd never have figured this out. My tray didn't pop out this easily, though. I had to use needle nose pliers

[@KeyFobRob]

No problem. I'm pretty certain they don't make it really straightforward to keep the customers coming back to the dealership for even simple fixes. The newest for Audi makes is even more ridiculous.

[@thefadden]

Good tip about the pliers. I couldn't get mine to budge just using fingers.

[@FayeIL]

Thank you so much for this! I've had my A4 for a few years and this is the first time I was able to change the batteries myself, without asking someone.

[@KeyFobRob]

Glad it helped!

[@mqadoc1]

It is an excellent and easy video to follow. The only problem is that you didn't tell us how difficult it can be to get that battery tray out. I had to have another person hold the fob while I manipulated the tray. I wasn't stron enough or dextrous enough to do it myself. You made it look easy!

[@KeyFobRob]

It can be pretty tough to get out. Glad you were able to get it sorted out

[@CDMVIDZ]

Hahaha, same! :) But yes, this video was excellent and just what I needed, thank you!

[@thesilenthero422]

When I got the low battery alert I thought I would have to send it in for some special battery replacement. What a relief to find I could do it myself with batteries I already had

[@KeyFobRob]

Absolutely! You got this

[@garypastore6246]

[@KeyFobRob]

Glad you found the video helpful

[@silversleeper484]

Hello Key Fob Rob, Bro thank-you very much for posting this up. I have a 2019 A4 Avant and I just could not have figured out how to remove/replace the battery without your help.

[@KeyFobRob]

Glad I could help you out!

[@chetw5372]

Thank you for posting this video. It was short, straight to the point and extremely helpful. I lucked out and had CR2032’s on hand. Same FOB as my 2018 A5.

[@KeyFobRob]

Glad I could make you're day just a little bit easier ;)

[@AllSingingAllDancing]

Thank you for posting this. I couldn’t figure out how the heck to replace the battery. You rule!

[@KeyFobRob]

Glad I could make your day just a little bit easier

[@neilfrost5630]

Great guide. Only thing I would add is try to avoid touching the faces of the new battery with your fingers as the oils on your fingers can affect the connection.

[@kimbobimbo1975]

Thanks for the vid.. saved me a few quid. I bought 6 of the batteries for a quid at my local pound shop. After chipping 3 finger nails used a hair grip to get the tray out it was pretty stuck in there.

[@KeyFobRob]

Glad it helped

[@maggie32summers60]

Thanks! If I hadn't seen this video I would have broken my key fob trying to open it ! So thanks again!

[@KeyFobRob]

You are welcome!

[@Lyra348]

Thank you so much for this video. Struggled a bit but thanks to your video I could do it finally !!

[@KeyFobRob]

Glad it helped!

[@charliejeane]

Hey, great video and well explained. Just changed my A4 key battery. Blessed and grateful for your content ❤

[@KeyFobRob]

Awesome! Thank you!

[@RoySmith-j8i]

We struggled with this until we read the comment about pressing in the release buttons “C” and at the same time pushing the thumbs forward to slide the battery tray forward and out. It helped to wiggle it from side to side a little . Then it slid out nicely.

[@asrikant7238]

Worked! Thanks. Getting the tray out was a bit more difficult than I thought it would be, but managed eventually.

[@KeyFobRob]

Nice work!

[@faizanrehman1688]

Literally a life saver dude! Thank you so much beats going to the dealer and getting ripped off 👌🏽👍🏽

[@KeyFobRob]

That is fantastic! Glad the video could make your day just a little bit easier!

[@jennettcrawley]

Done & dusted! Both keys, thanks Rob! I did need more help in the form of some spiky scissors to get the tray out though. Bonus I didn’t break a nail 😅

[@KeyFobRob]

Ha! Nice work

[@frederickmackay2234]

This tray release is unnecessarily difficult, trust AUDI to make it a pain to remove a battery, thanks to your video Rob, your tip to use the key solved the problem. My other car (BMW) is so much easier compared to this design.

[@KeyFobRob]

You bet! Glad I could help make your day a little bit easier!

[@Daniel_Bentley]

Use a fork when trying to get battery thingy

[@ricardomontanari2124]

Amazing, thanks so much. I was trying to figure it out for ten minutes prior to watching this lol I think the squeeze bit was a bit jammed on mine. Many thanks for the upload.

[@KeyFobRob]

You're welcome. The tray can definitely be difficult to slide out.

[@Boidboy]

Thx. I too had to use needle nose pliers for removal of battery pack. Video helpful. Went from dead fob to alive fob. Have not yet started the A4 yet, tho.

[@KeyFobRob]

[@daughterofthesun]

Thank you so much for this easy to follow video! Took me about two minutes from start to finish!

[@KeyFobRob]

Glad it helped!

[@tstrauss33]

Thanks! I did this, but found that squeezing while trying to pull out the battery actually PREVENTED the battery from coming out. Skip that and you're golden. Great video - thanks!

[@fresorger]

For those struggling to get the battery tray to slide out, I found it better to wiggle it firmly with my fingers while pushing the two buttons in. The wiggle action frees it quickly. I had a hard time using a metal instrument because i had to push so hard it damaged and scrapped the plastic.

[@KeyFobRob]

Great tip! These can get pretty stuck

[@sergioamador4729]

How cool that my car told me a heads up that the battery was running low. Thanks to the video just swapped out batteries.

[@KeyFobRob]

Is there a better how to video on this?? I think not! Thank you! Quick and easy!

[@KeyFobRob]

[@guangye]

Not necessary to use the key blade to pry out the tray. Though it might be slightly easier, but high risk of scratching the tray. Slowly wiggle out. Patience is the key.

[@dingdong2103]

slip some silicon grease to the sides and next time it will slide out nicely :)

[@katiescott7286]

Thank you!! They were going to charge me $40 at the Audi dealership 🤣

[@KeyFobRob]

Great! Glad you found the video helpful!

[@timbailey2521]

Hey, thanks for the video! Slight issue with it though, the car is still saying the battery is low? Any advise would be great! Thanks 👍🏻

[@KeyFobRob]

Try doing both fobs?

[@timbailey2521]

[@timbailey2521]

Hi, tried the spare key and that one doesn’t come up with the light anymore, it might just be a faulty battery so I will try another one, thanks 👍🏻

[@brandonfountain835]

Great video rob , id do a follow-up video eliminating that last step where you use your key to tear up the bAck of the remote lol . Once you squeeze the two tabs together, use about 3 pounds of pressure and you battery slides right out 👍🏼👍🏼

[@KeyFobRob]

Eh, they aren't all that easy to get out. I do have some videos with this same fob. For instance - kzbin.info/www/bejne/qoDIhoqbmLR1mq8si=xBsIVUTCXaD1R7JY

[@sarfz87]

Hi. Do you lose the configuration of the key fob to your car when replacing the battery?

[@KeyFobRob]

Nope

Muchas gracias 😊😊😊 hoy tuve que cambiarla y busque en KZbin y me salió usted muchas gracias por la explicación que es de lo mejor

[@KeyFobRob]

Muy feliz de poder ayudar a hacer tu día un poco más fácil

[@jdrukman]

The tray can be really hard to get out. I recommend using a jeweller's screwdriver - it fits in a lot easier than the edge of the key. Be careful: I ended up popping the tray out with such force that it went shooting across the room.

[@raquelclayton3287]

Not all heroes wear capes. Thank you!!

[@Getlost55]

Glad i watched this video because I was about to break my key fob in half not knowing any better.

[@KeyFobRob]

Ha! Glad you could get it sorted out

[@glennmelrose607]

This works exactly the same for a 2018/2019 S4. The only difference is cosmetic; the backside of the fob has the large "S" emblem on it. The internal stuff is the same.

[@KeyFobRob]

Awesome! Thanks for the info.

[@polehuggermusic]

Do you have to pair it or something cuz I put new batteries in and it's not working anymore

[@KeyFobRob]

No need to reprogram - Try some fresh batteries - CR2032 - amzn.to/2DecUq6

[@polehuggermusic]

@@KeyFobRob it finally worked lol thanks so much! It's too bad that Audi makes the Fobs out of thin plastic. Very easy to break but it works again for now! Thanks again

[@stanj1099]

For my 2023 A4, I had to really wiggle the slide with the battery to get it out. Using the key for leverage did not work. Another video said to wiggle the slide.

Using the key to lever out the battery cradle is risky, as you might damage the cradle. The cradle comes out readily if you simply jiggle the cradle while pulling it gently. No levering with the key

There is no need to use the key. Just squeeze the sides, that mechanism has 2 sets of latches, one for the metalic key and one for the battery, just squeeze a little more for the battery. Want to see how the mechanism works, play the video at 0.25 speed. That being said, thank you for the video, had no clue where is the battery and how to take it out.

[@bap2837]

I believe I broke my fob doing this. I was able to remove the battery compartment to change the battery, but now the side buttons won’t spring back open. They stay compressed. So when I try to put the hidden key back into it, the side buttons won’t catch/spring open anymore. Any way to fix this??

[@KeyFobRob]

The battery tray likely isn't pushed in far enough

[@bap2837]

Yes, unfortunately it is. Even when the tray is out, the side buttons stay depressed. It’s like there’s a spring missing or something.

[@tyhyancey]

This did not help me but I figured it out anyway. With this video, I struggled with where to put the key and which direction to apply pressure with the key while trying to access the battery. When I tried this, the "battery drawer" did not budge. Plus, I was risking hurting the plastic with the end of the key (multiple scratched) due to the two questions already mentioned about the key (placement and pressure direction). I then watched two other videos on the same subject with the same key fob. Neither of them referenced using the metal key at all when trying to open the "battery drawer." They both said to press the two buttons while trying to put out the drawer. They both also mentioned moving the drawer side to side while trying to pull it out. The second video did not make much of a fuss about rocking the drawer side to side, so that video did not solve my problem. However, the third did. It said one really needs to work at rocking the drawer side to side and said it was because the drawer can get stuck. I then tried more mussel and worked it out (without using a key). Lastly, I would like to mention that as the key fobs age in our pockets and purses (and get more and more dirt and fine particles that work their way into our key fobs) I suspect the wiggling side to side is going to become more and more difficult - and therefore, needs to be emphases even more than it was in the 3rd video. (If this post that took me 10 minute to write helps at least one person, it will be worth it. However, I wont be holding my breath!) ... there you go little posted buddy, off into the cosmic online intro-verse never to be heard again...
