Kidde Fire Safety Reviews 

Went off at random times

We bought 6 Kidde hardwired smoke & co detectors for our home. 3 were manufactured in April 2023 and 3 in June 2023. They were installed by an electrician November 2023. Kidde claims they last 7-10 years! Hundreds of dollars for these units. I moved in at the end of February 2024. From the first day these alarms would go off for no reason. I cleaned them weekly with a cloth by dusting and vacuumed them weekly to prevent dusty or insects from setting them off. Nothing helped! All hours of the day and night one by one each one got worse. I removed each one. I removed the batteries, changed them, drained the memory as stated on Kidde website! Nothing made a difference. I went online and discovered that the most nuisance alarms were from the 900-CUAR model which is what I had. I had them all removed on 8/31/26 and paid hundreds of dollars for the 30-CUAR! I called Kidde customer service yesterday 9/1/26. I reported all this. After almost an hour with them, the lady told me there was nothing they could do for me. They are LIARS! Don’t buy their products! I have wasted a good $1,000.00 on Kidde and they refused to send me replacements for the 900’s that they PROMISED are good for 7-10 years! I will never recommend them to anyone! They are not a good company!

1 star is a gift. These are junk. We have issues for years. Replaced all new batteries, etc. junk do not buy. No customer support.

I replaced 7 smoke detectors with new kidde detectors that were supposed to last 10 years. After just a year, the alarms started randomly going off usually at 2am. The alarms are not easy to reset or quiet leading to several early mornings where an alarm was thrown into the yard or crushed with a hammer.
There are much better options out there and I have replaced all of my kidde detectors with other brands.

Like many others, we were woken up in the middle of the night from this smoke detector for no reason. If the batteries are dying why can’t it just do the regular chirp?? Would not recommend unless you love waking up with a huge adrenaline rush at 3am

Absolute rubbish! Drains batteries so quickly that you need to replace batteries at least once a month!

I ordered smoke detectors for my house, replacing the exact ones that were originally installed. I paid $219.00 for two of them. What the seller sent me was a different version with the cost of just $58.00 each. I reached out to the seller and they never responded. Americamart and Kidde are a rip off and I would not recommend buying anything from them

False alarms! Three times in a month at the EXACT time of day (3:00 am!) I followed all instructions (like blowing compressed air in). DO NOT BUY. They will not admit there is a problem.

Kidde Electric Smoke/CO alarm 30CUA10

NEVER had a problem like this with any other smoke alarms and other alarms in other parts of the house do not do this.

So far 3 of the 4 smoke alarms I have purchased have malfunctioned within a year. Customer service has done nothing to fix it. Do not buy this product

Very poor product - K10SCO: Smoke & Carbon Monoxide Alarm states a warranty of 10 years but failed in less than 5 years. Tried cleaning & changing batteries with no luck as it just beeps continuously (faulty product). Customer support number available online just goes into a inbox that says no one is available to pick up...DO NOT BUY

Why don't you use rechargeable battery technology on certain detector since they are always plugged in its stupid to use AA batteries.

What a joke - I just had a "rookie" (it admitted it itself) trying to help. Customer service is outsourced to "RSVPComm" as I had to an email a pic and it went to a "spam" address. I provided a picture of a disabled alarm. Her manager says it doesn't look like it was completely disabled by the fire dept when they had to respond to my elderly mother's entire house going off in the middle of the night (no smoke). They said it went off due to dust. How do they know? Now I have to go buy one for her since they are not guaranteeing their product. This is on top of having to get all 6 units replaced 7 years ago as they do not last their 10-year warranty period.

Consumer reviews and forum discussions highlight several recurring issues with Kidde CO detectors:Frequent False Alarms: Users heavily report interconnected systems and stand-alone CO/smoke detectors going off in the middle of the night despite no smoke, fire, or detectable CO present.Premature Failure: Despite marketing a 10-year lifespan, many detectors begin showing "end of life" errors (e.g., chirping twice every 30 seconds) or battery faults within 3 to 5 years.Customer Service: Buyers consistently cite poor experiences with support, including extremely long hold times, unreturned emails, and delayed delivery of warranty replacement units.General Brand Consensus: Due to these persistent issues, many users in forums like Reddit advise switching to alternative brands known for greater reliability, such as First Alert or BRK.

What a shower of s…. Do not buy this brand, if you have ant issues it’s like contacting another planet.
Why do companies like this hide behind contact form, give people a phone number.
Absolutely disgusting company.

These alarms used to be great until Kiddie took over. I bought a four pack of smoke alarms and 3 out of 4 beep all the time. They are brand new and have new batteries as well as have been cleaned multiple times and still beep all the time. One of them won't stop at all and we cant even use it. Over $100.00 and don't work for crap. Nice😡

My alarm is malfunctioning. The company confirmed it is defective and said they would send a replacement in 7-10 business days via FedEx. After 14 business days and no replacement I called again. I was told the replacement is on back order and they do not know when it will arrive. You wait on the phone for 30 minutes for Customer Service to answer. Kidde makes DEFECTIVE safety products and there is no urgency from the company to replace a defective product!

I purchased a Kidde P4010ACSCO hardwired smoke and carbon monoxide alarm with a 10-year sealed battery from Home Depot in April 2022 for about $79. In June 2026, the alarm began going into false alarm mode approximately every 154 minutes, making it completely unreliable.

What has been even more disappointing than the product itself is Kidde's customer service. Home Depot directed me to the manufacturer because the unit is covered by a 10-year warranty. After three emails, one phone call, and an online chat, I still have no replacement and no meaningful resolution.

A smoke detector is a life safety device. If it constantly false alarms, people begin to ignore it or disconnect it, defeating its entire purpose.

Based on my experience, I cannot recommend this product or Kidde's warranty support. I expected a 10-year alarm to last much longer than four years and for the manufacturer to stand behind its warranty. Instead, I'm left with a $79 alarm that is unusable and a company that has not honored my expectations for customer service.

I will not be purchasing Kidde products again.

Do not buy this brand! They are nearly impossible to contact. Non existent customer service. When calling expect to get an extremely long wait. They do not respond to emails which leads me to believe all customers are having problems.
Go for another brand.

Wired smoke detectors that are supposed to last 10 years have failed three times so far in ten years. So basically at least every couple years they fail extraordinarily LOUDLY, screaming Fire and beeping at 3am, waking everyone up like a brutal torture device. I have to climb on chairs and spray them with compressed air and then a few nights later it starts all over again. I don’t think they care about this. They just send more crap units. They are sensitive to dust and spiders so i spray them regualary and they still fail, screaming in the night. I hate them. Now they are sending new units and saying i have to go buy adapters for the wiring harnesses!! They refuse to supply new adapters!!
