Thank you! My late husband was my fix it guy. I have to learn to do things by myself.

We are so happy that you shared this video. Took your instructions step by step, and the car now opens. Thank God; what a relief! Merry Christmas to you all!

This is the first KZfaq tutorial I’ve tried out that actually works lol. Saved me money and took about 5 mins to do. Thank you!

Yep, works like a charm. Found the battery at Walgreen, used a dime to open the fob, done in minutes. Thank you!

DUDE! you saved me hundreds of $$ at the dealership. Thank you!

Great video! Thanks so much! Btw, if you live near a Barnes and Noble, the cr2016 battery is only $1.99 ea.

I followed your instructions and inserted the new battery. I paid $7.88 for a dual battery pack. Did not have to go to the dealership for a key replacement. I'm back in business. Plus, it was easy peasy. Thank you for posting your video.

This video was awesome! So simple and informative, straight to the point. Thanks a million!!

First time changing my car remote battery myself. I love that this video was very simple to follow and straight to the point. Thanks for sharing.

Thank you so much !!! My battery died and I started using my spare key and that on died !! I went to my local jewelry and brought the battery!!! I use your vid and I change them both yesterday!!! The battery's were $5 bucks !! Did it in 2min!!! Thank you! Thank you!!!!

thanks a million. finally I can open the door without having to use the keyhole. great video

Thank you. I was wondering what to do until I decided to search on KZfaq and I found this video. It actually helped me to solve thus problem.

I was feeling a sense of Oh No!! My key won't open my door. What do I do now? During this shelter in place, Pandemic. The idea came to me KZfaq!!! And I found you. Had myl dad buy me the battery, as you suggested and Happy to report it works brilliantly. Thank you for your video. Hope millions will watch it and benefit as I have.

Never would have figured this out on my own but this video walked me through without a single snag to the process. Never to old to learn a new trick!

Thank you for posting this! I just changed the battery in the key fob for my 2015 Prius C and didn’t need any additional help. ☺️

Thank you for such a clear, easy-to-follow video. Everything worked exactly as shown.

Thanks so much. This is such a helpful video. Just like panic button in the video, the buttons in my fob popped out very easily so I recommend replacing the battery on a big table so that buttons don't fall on the floor

Very good video, right to the point, thanks. In just under 4 minutes I learned how to change the battery in my Corolla's key fob.

Thank you! You saved me lots of time and energy - physical, mental and emotional!

Thanks for this, my fob has been dead for years so it's nice to have it working again.

Theres actually directions on the inner part (that houses the battery) to just pop it open with a coin. Worked like a charm! And to think I was actually entertaining the idea of buying a new key fob smh....the batteries are $5! Making a trip to AutoZone today!

This is in fact a very simple and helpful video. I replaced my car key's battery using this video. Really, appreciate.

Best video on KZfaq thank you sooo much

toyota was trying to charge me $10 for this. thank you so much for showing us the way :)

Thank you...I was so "skeered" of trying to do this but it WORKED BEAUTIFULLY! thank you!

Thanks for the advise to replace the battery on my Camry toyota battery. I'm so glad I don't have to go to a dealer and be charged for it. Thanks again. That was so easy!

Badass. Thank you brother. Not sure what they would have charged me at the dealership but I imagine it be a pretty penny. You can definitely tell that they didnt want anyone trying this. Haha

Wow.. THANK YOU! I used a dime to open the fob and popped open in one second.

Thank you Jordan Peterson! You help out in many ways!

Thank you!! It was a struggle....I was afraid I would pull something apart and wreck it, but I did not, and fixed it myself instead of going to the auto parts. I found an extra battery and did it myself!

This was really really helpful and saved me a trip to the dealership bc I thought my key was broken lol. Very easy to follow!

I would have never guessed. Thanks.

Thank you for the video. Very easy to follow and easier than I thought. Definitely saved me some money from going to the dealership.

Superb video. Direct and to the point, unlike some others which go on and on.

loved it! you saved me 150 bucks!! i just need it a new battery! god bless!

Thank God for the keyhole when the battery dies!! Great video, including the panic button reinstall! I had to do that too! I commented before but had to come back to do this again!!well done video. Thank you! 🙏

I didn't realize you could just pry it open. Thank you!

thank you mr.peterson!

Amazing video thank you so much! I went to Autozone they accidetanlly sold me CR2032 for my 17 corolla, but I actually needed the CR2016. Love your video helpmed me so much!

Thankyou! Great Vid! I did not know this could so easily be fixed and I was able to do it on your instructions, I have been walking around for months using my key manually! I thought I needed a whole new key.

Awesome, was about to call up the dealer about this. Saved myself $$$

Bro video was perfect thank you

I like your efforts

Thanks for the upload video man. Probably saved me $200 or more for a battery. I went with an Energizer Lithium CR2016.

Thanks quite simple with some direction

Thank you for taking your time, well explained, gave me confidence to complete battery replacement task ! ! ! !

THANK YOU!! These instructions worked perfectly for me.

That was great! Thank you very much! God bless you!🙏

Thank you! Great video - easy to follow and no rabbling!

Thank you! Made changing the battery smooth.

And .. "just like that" THANK YOU lol

Thank you. You did not mention the writing on the inside that says "Use Coin to open" with an arrow. That was important, but I found that information on another video. Maybe update yours?

That was super easy!! Thank you!

@Helpful_DIY Great video, your screwdriver method helped me open the key fob quickly, Thanks! Edit: I'm an idiot nevermind lol the negative side is on the bottom I really appreciate the video, I just put a down payment on a 2017 Corolla LE this week and the Key Fob stopped working; this video helped me get it working in no time.

Thank you and God bless you sir... you're like a Messiah - a very present help in trouble

If I replace the battery and it doesn't work to lock/unlock the car. Will it be the small motherboard that will need to be replaced?

Just did it. And it works. 👌🏽Thank you

Thank you very much. Feels good to get something done in simple ways :)

Great video, Thanks

Thank you very much I save money

Excellent video, battery changed. Thank you!

It is actually very, very difficult to get the new CR2016 coin battery into the key fob unlike the video shows where it clicks in nicely, and I think Toyota's greedy ass intentionally designed it this way so customers need to go to the local Toyota dealership to spend like $100 for key fob replacement instead of replace the battery themselves. No, I didn't break anything while getting the dead battery out because in the end I eventually managed to insert the new battery, but it took a tremendous amount of effort and time to do so. You have to hold down on the battery hard and pry the battery holder towards it to actually be able to lock the battery into place. So if you want to replace the battery by yourself you have been warned.

This video was very helpful thanks a lot 🙏🏽

Thanks a bunch, great easy to follow directions !!

Thanks so much for this video! Right to the point and so simple. 🚗🔑

thank you for the help!!!

That was really helpful, thank you so much!

Excellent job 👏

Can you use a Duracell battery?

This works great! Thank you.

Thank you so much

Very simple, thanks for sharing!!!

This worked perfectly! Thank youuuuuu!

where can you buy the battery at ?

Very helpful, thank you 👊

I found cr 2032 will it fit ?

Thank you

holy shit you sound like badger from Breaking Bad xD thanks though! i wanted to try cr 2032 but it seems 2016 is only the one recommended for toyota key fobs

Thanks ❤

Make sure you get the PANASONIC brand batteries! You can get them on Amazon! I bought Energizer and Duracell CR 2016, and they did not work! When they say “exact same batteries”, that’s exactly what they mean!

Thank you Man 🙏

Life saver!!!!! 💯💯💯💯

You are a lifesaver thank you so much

Thanks for the video!

can I use CR 2032 ?

Thanks man. Really helpful!

The specific orientation you mention in the video isn't important. The only thing that matters is that you don't put the battery in upside down. The entire top of the battery is the positive side and the entire bottom is the negative side. Also, it's easier to pop open the outer housing with a coin than using a screwdriver.
