DIY - How to replace remote fob battery in Audi A4, A5, Q7 and TT 

Energizer Battery - CR2032 - amzn.to/2DecUq6

3 years later this video is still a life saver

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

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.

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

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

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!

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.

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

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.

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.

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.

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.

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

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.

Short, clear and to the point unlike a lot of similar videos!

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

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

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

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.

Simply perfect explanation. Great video, changed my battery in a minute. Thanks!

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

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 👍🏼👍🏼

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

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.

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.

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

Short simple and perfect form of "how to" 👍

Your a rock star! TY TY TY, I destroyed my other fob cost me$646+ tax, Really appreciate your time. Gary P

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.

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

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.

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!

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 😅

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.

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.

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

Perfect demo Rob, many thanks, my battery tray was sticky though with 6 years of use!

Thanks to your tutorial I was able to do my key 🔑. Your Awesome bud!!!

oh my gosh your RU-vid name is perfect and I'm sure you just saved me hundreds of dollars from scheduling a service appointment at my local audi dealership, thank you so much sir! lol

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

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.

Thanks for sharing this. Saved me from breaking mine.

Thank you! You made my life much easier with this simple how to video!

Wahoo !!!! This video saves my day !!! Thank you for sharing!

Perfect for what I needed. Thanks a million!

Wow! So simple! Helpful video for my A4

Thank you! Straight to the point ! Love that !

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

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.

Thank you 😊 so helpful, I would never figure that out 😀

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

Thank you! 🙏🏻

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

I just replaced the battery on my 10 year old A5. I should say my daughter did God love her.

Thanks Robbie.. easy-breezy with your instructions..

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

Told my wife it’s easy she must figure it out, only to realize I can’t myself 😜 thank you so much

Thank you! I couldn't for the life of me figure out how to get the stupid thing open!

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

You don't need to push with the key. Just press the tabs in firmly and wiggle it out

you are the best in the west bro!

Just changed mine. 2021 A5 coupe. Thank you.

Thanks! I got a message to replace my battery, but did not know how to do it.

Thank you, easy to follow 👍

Worked like a charm. Thanks!

PERFFECTO!!!!!thanks a million!!!!

Thks do much saved me a lot of money 💰 no need to go to dealership

Thanks. I was definitely about to break mine trying to split it apart 😂

Thank you for saving me a trip to the dealer!

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...

I love your videos they are the best

Thanks for the video. It makes these tasks simple.

thanks for this. ive literally been using the emergency key for the car and get embarrassed as the alarm goes off almost every time i go in

Thank you, Mr.TwoScrapes

Hells Bells !!! Watching from Oak Cliff, TX ❤

Thank you! Worked perfectly!

Lifesaver thanks a lot. The audi dealership near me are douchebags, they charge 6 times the amount for changing the batteries and insisted only they can do it.

Hello from Croatia and Thanks you help me 🥂👌

D best how to video online ❤️

Saved me a trip to the dealership! TY

So simple...thank you!

Watching today, because Im a Man and Id be embarrassed if I took this to the dealership😂 thanks Key Fob Rob

Many thanks! Saved a few quid..

Perfect how to video!

Thanks! I used a fork to get the tray out. Why make this so complicated 😮

Result. Very helpful. Many thanks

Thanks for the video, managed to do it but it wasn't easy. Not the best design.

Perfect. Great help. Almost took the key to an Audi service centre. Lol

Thank you it helped me a lot 👍

Thank you !!

Thanks mate, saved the day

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.

Thanks a million, just figured this out before I decided to try and take it apart a different way, not the best idea tbh :(

This is how all “how too” videos should be

Thanks , no need to apply force. Do it gently as he did with your key.

Works on my 2016 UK A4 Avant V6 Quattro thanks.

Thank you. Very helpful

Thanks again...I always forget.
