Replacing the batteries in a Kidde carbon monoxide alarm 

12/20/2023. Thank you so much for posting this video. My daughter and I were trying to pry if off the wall. Saved by your video 😅

Your efforts 5 years ago have come to the rescue yet again! Thank you very much for posting this information about the Kidde Carbon Monoxide Detector. Mine was attached to a wall and had been plastered in place so that the mounting bracket was covered. Thanks to your video I was able to loosen it enough to slide it off the bracket and change the batteries without damaging the unit or the wall. Whew! Many thanks, you may never know how the least little thing can help others!

I cannot even express to you how much your video helped me understand what to do with this thing! I truly thank you so much for this.

Thank you so much...single female living alone, could not for the life of me figure out how to get to the batteries or how to get it off the wall short of smashing it with the knife I was using to pry it open I decided to look on RU-vid and found this!!! Who knew it would just slide off. Replaced batteries and no more annoying loud beep you've saved my sanity. THANK YOU SO MUCH

I am so glad you had this tutorial! I couldn't find anything on how to remove this alarm and change the batteries.

OMG I was the only one who woke up by this sound. I searched around the house to find out what this sound was. When I found it I saw the batteries had been corroded (white stuff on the ends) so I most definitely replaced the whole thing the next day. Thanks for this I was panicking

Thank you SO much! This was first time ever changing the batteries all by myself and I was thinking I had to pry it open, too. You saved me a lot time time and effort. I appreciate you!

This unit saved my life when I was living in an RV. Today I have 2 of them as backups.

Man... thank you so much! I could not figure out how to take the alarm off the wall. I didn't realize how easily you could just slide it up lol.

My housemate and I have spent the last 3 hours trying to work out why our CO alarm was going off despite having a reading of 0 ppm. We eventually found a second CO above the cabinets in our kitchen which was this model of Kidde alarm. After changing the batteries and watching your video, we can now finally go to bed at 2am without panicking. Thank you so much.

I know this comment is eons late and you won't see this message because of that, but THANK YOU SO SO MUCH! I just moved into my own apartment and the landlord didn't come check on my beeping apartment. It was only beeping 1ce every minute so that's good news. Now I know to change the batteries. And HOW ON EARTH to SLIDE IT OFF THE WALL. Please keep this video up for future people needing advice. You saved the day! :)

Thank you for this video, my alarm starting beeping like this 2 days ago in my LQ horse trailer. Had no idea how in the world to get it off the wall, much less how to get to the batteries. So appreciate your video. :)

Thank you so much for this video. The apartment complex never showed us how these worked. Turns out a battery was leaking in it and set it off at 1am, scaring my entire family. I spent 30 mins trying to figure out how to open it to check the batteries.

I found this very helpful as we were not given any instructions on this so I've just changed them myself so fingers crossed it was just the batteries

Thank you, Thank you so much for making this video on how to change the Carbon Monoxide battery🙏🏽 when our home alarm went off this morning, l honestly did not know what to do and how to slid out the entire compartment, it was very frustrating and confusing. And the sound was so annoying too. I had to come to RU-vid looking for a video that can help. Your video showed me everything l needed to know and do. Thanks again and God Bless You🙏🏽

Thanks for making this video. It is two days to Christmas and that would have driven us crazy trying to get it to stop! Your video was easy to understand and saved our sanity! Merry Christmas!

Thank you so Much. I had a knife trying to pry off the front. I have the exact model. I was going to call the fire department. You just saved me alot of hassle.

Thank you for this, mine did this so early in the morning and I was the only one who looked up a video to do this.

So grateful for this video when mine started chirping at 1am waking me up! lol!! Glad you showed me how to get it off the wall so I didn’t have to resort to a hammer!

Your a godsend my family was visiting the remote home and did not know what to do as this same unit had constant blaring alarm and I found your video. Thank You!!

Thanks! I was pulling every which way trying to open it up to replace the batteries in order to stop that maddening chirping! You made it so simple.

Thank you sooooo much! I tried EVERYTHING to get it off the wall and even sliding didn't work, after seeing this video I persisted and sure enough it DID slide off! Saved my sanity! THANKYOU!!!!

there is another intermittent chirp every 30 seconts.. if it is 2 chirps evry 30 seconds it means the unit has expried (end of life - after 10 years of inutial use). and a single chirp every 30 seconds means one or more of batteries are low in charge, according to manual i read.

Thank you for making this video, it helps me to figure out how to remove this detector on the wall coz it needs a new battery to stop this annoying chirping.

Thank you so much, I've been trying to get that unit off my wall for the past 2 days

Thank you for sharing. I replaced the batteries in my Kidde carbon monoxide alarm with ease after watching and following your instructions here. 😃

Thank you so much!!! I didn’t think it worked until the beeping started and had no clue how to replace until this video!

Thank you for this video. I looked it up because I wanted to check if the beeping just as you put the last battery in is normal even on a new model and it seems to be.

Thanks so much, i couldn't figure out how to take it off in the first place , first time home owner, this video was so helpful after waking up 5 in the morning with that beeping noise

Thank you! Wish I would’ve come to your video first. I wasted so much time watching others. thank you being short and to the point. You are awesome!. You got a new subscriber 😊

Thank you so much! That was very helpful, just what I needed to know.

Thanks for the video. My CO monitor started the low battery beeping at 3am (of course) and I just followed your instructions and replaced the batteries - without ripping the whole thing off the wall.

Thank you so much. I had no idea what was going on and thought we needed the fire department. It's called a Battery Operated Carbon Monoxide Alarm 9CO5 for anyone who needs it!!

Thank you so much. Recently lost my husband and had no idea how to do this.

Great info! I nearly broke the one I have trying to pry from the wall.

Thanks for this. I’ve just nearly ripped mine off the wall in our motorhome. Frustratingly there are no instructions in the booklet that came with the unit and ours was fitted by the motorhome manufacturer. 👍👍

Thank you for saving me the time I would have spent trying to figure out how to open it.

Omg this is the Exact kind I’ve been looking for

Thank you!! I couldn't for the life of me figure out how to get it off the ceiling... :)

Thanks, was having trouble removing, then saw your super video

I was getting crazy , my dog was shivering 🙏 Thank You so much !

Thank you for making that video ! It really helped me

This was so helpful! Thanks so much!

Thank you so much for your video. Was I happy to see a video with CM alarm that looks just like the one I have. So glad I looked at your video Before I took it down because I'm sure I would have made it more difficult than it was. Two thumbs up! Thanks again!

Thank you!! I was going crazy trying to figure out how to do this!

Very helpful video thank you so very much 🙏👏👋

Thank you for this video! Very helpful.

Thank you this video is still relevant.

Thanks for keeping me from breaking the plastic cover!

Thank you so much for this video!!! You’re the best

Thank you for saving my sheetrock!

Thank you so much you helped me today I had no Idea how to remove it from the wall

Thank you for this video! I literally have a headache from that beeping and your video showed me how to remove it and replace the batteries so I don't hear any more "low battery" beeping. *sigh😊

Life saver man. Apartment had this unit, couldnt tell how the hell it came off. Thanks for saving me the pain of coordinating with maintenance (Night shift, I get no respect, am I right?).

Saved my eardrums, thanks

Thank you so so so much. It’s the weekend and the HOA super isn’t available. This thing was driving me bonkers for 27 hrs. Done ✅

Thank you soo Very much....the beeping was causing lack of sleep!!

This was hanging on the wall when I moved in, so I just assumed it was hooked up somehow like the thermostat. Mind blown.

Thank you. You saved my day

Thank You for this, Mine was being soooo annoying Your a Life saver!

Thanks to you, almighty one! Almost broke mine 😂

Thanks this is the exact alarm i have

Thank you! THAT WAS EASY!

I think I love you! Thanks for this!

Thanks for the help ours was chirping a lot

Excellent, thank you

Perfect, thank you!

same one i'm using, thank you

highly recommend this purchase!

Thank you. Very helpful

Thanks for saving my life lol!

Thank you sooo Much!!

The alarm beeps 2 or 3 times in a while ? Wasn't before anything, could be the battery or something serious?

Hello, in normal operation do any lights illuminate to indicate that the unit is operational.

Thank you! Yes, I too was having a hard time figuring out how to remove the battery cover on these "rectangular" models. I was letting my inability to figure it out affect my manliness 😁. There are a few slots, etc. that are tempting to try to get at the batteries, but theynare not the way. How did you figure it out - trial and error?

So very glad !

Thank you very much!!!!!!!!

The one thing I forgot when I took out batteries is to see which way each pointed. Not clear in your video. I thought I put in right way but ever 30 seconds it would chirp. And my new batteres were NEW.

You saved my ears

Thanks for posting

Great Video!!

Mine still beeps every 30 seconds even though i have replaced the batteries with brand new Duracell ones. Ive tried resetting but still it continues. Any explanation for this?

I know this was 6 years ago now, and it may be different as it doesn’t have the Kidde logo on it so it may be slightly different but: - A constant tone like heard at the start of the video indicates the alarm is malfunctioning and needs to be replaced immediately. - A chirp every *30 seconds* means the alarm has a fault, and should be investigated or replaced. - A chirp every *60 seconds* means the batteres are low and need replacing. - 2 quick beeps every 30 seconds means the alarm has reached End Of Life and needs to be replaced. As I said, it may vary on this model but it appears to me (and I appreciate it was 6 years ago and the unit is probably replaced by now) that the device was malfunctioning then gave a fault chirp so I think it needed replacing. My alarm looks the exact same however it has a Kidde logo on it and says the model number 7CO, so it’s the same model but it has a lack of logos on it.

Thank you !

thanks it was my first time so :P

Thank you

MINE ONLY HAS 2 BATTERY SLOTS. IS THAT RIGHT?

Thank you for your video. As you said, I tried to pull out, but it won't work. I said to myself, I am better going to RU-vid to see how I can reach the battery compartment, Now that is what is my answer. I think after removing the battery, you should press the reset button for 15 to 20 seconds to drain the electric charge out in the capacitor. Plus, use the air can or blow by the mouth in the hole where the sensor is to blow out the dirt, insect or spider web out before putting it back.
