You're welcome 🙂 Happy to assist

Lol still working on mine at 2 am

@@nick16652 You surely need that marital smoke, it's the only way to test the smoke detector to see if works.

Great, hope new ones works perfect. Just curious, why did you change Smoke Detectors with Smoke and Carbon Monoxide? Is there any reason?

Well the date said they need to be replaced in 2022

@@GFLProductionsGuy27 Yes, I understand. But I meant changing from Smoke to Smoke+CO. Why not change Smoke with smoke!

Hello, May be double check the direction of the batteries. Also, please press reset button, alarm will go off once and then it will reset. Not resetting is the most common issue why Detector keeps beeping. Also, on Smoke there is expiry date, which is 10 years from Manufacturing date. If that date is passed, then Smoke Detector need replacement.

Hello, May be try using bit of added force, also, make sure you are turning it on the clockwise direction to open. Latching system on these Smoke Detector is very simple and doesn't require any special tools. Sometimes if paint or paint touch up is done after smokes are installed, paint drips to the frame and dries off. Try cleaning that and open. Please also check if your Smoke is with a built-in battery, which doesn't open but need whole unit replaced. Check face of smoke detector to see which one is it. There might be manufacturing date, if Smoke mal-functions within 10 years, it has a limited warranty and Kidde can be contacted for a replacement unit. Hope this helps. Please let me know if you have any other question.

Bro, I am a 200lb dude with significant arm strength and I cannot get this cover off. I’m going to snap it in half if I try harder. It’s insane lol…and the low battery is beeping all night.

Hey, there is a small white pin. It looks like a white mail head, pull that out and it turns.

@@6Sierra Thanks for the update and the information. I have never seen this pin, but seems like newer or older version have this.

@@6Sierra Mine has a pin too, but I ended up just ripping the whole thing off because I couldn't figure out how it worked 😂 Either way my problem is solved, I only wanted to disconnect it because it constantly beeps for no reason whatsoever.

This is news to me. I am not sure if they changed it on newer models. But i can share a video with you to show how to replace Smoke Detectors in which i also show how to change the connectors. Please see attached link- kzfaq.info/get/bejne/grFgbNGS07KqZ2w.html
